INTRODUCTION

Over the past 50 years, there have been many attempts to design and bring to market EPS wall systems that address all the requirements within the building code, as well as being affordable, structurally sound and functional. There was and is a need for a building system that is energy efficient, that is Impervious to moisture and air Infiltration issues.

A successful wall system, which is an important part of a functional building system needs to be designed that is appreciated by all the sub trades in the construction industry that work on assembly of building units, single family residential, multi-family, high-rise, institutional, commercial, industrial and other forms of construction.

Approximately thirty-five years ago I developed a wall system that addressed all those requirements and more. I was close to making submissions to the building code of Canada that could have revolutionized construction methods. That was back in the day when R2000 (super energy efficient low air infiltration) programs were being developed, and allowances could have been made to submit a design of a wall systems that had structural, air and vapour barrier integral within the system. I had worked with a company in the lower mainland of BC, called Sheltair Scientific, who I think were taken over by the Stantec group. They performed a fan door test on a rancher styled home. The test house was built using my EPS wall system, no exterior wrap or interior vapour barrier was installed. The wood-to-wood contact points were sealed with glue/caulking, the same at the contact points to subfloors. We did install a ceiling vapour barrier to facilitate the installation of the sheetrock on the ceiling to be able to depressurize the shell and rate the walls. Each stud space represented an airtight cavity. I witnessed smoke tests performed around the perimeter of a multitude of stud wall panels, this test house was built using 16” OC construction. The results of that test showed that we were within an eyelash of a full R2000 air seal rating. We are confident that with a few modifications we could have achieved a certification. Given the disastrous results over the past 100 years of the billions of dollars of damages because of moisture damaged buildings in British Columbia and other global locations where weather and humidity are issues.

There is now opportunity for a new approach to construction methods.

Many of the past and current panelized EPS wall systems didn't address the problems, they are more expensive and complex. This new Prefab system exemplifies the most simplistic and cost-effective design processes. Many of those who attempted to develop a wall system pursued an erroneous concept, that was to create thermal breaks, most of those systems have failed, or have limited success because of complexity and costs. The Nascor Wall system and Pacific Homes Smart Walls are two examples. Contact us for more information on problems with these two systems.

Wood for example, a 2x6 on edge has cellular properties that provides an excellent low conductive device with good insulating properties. The problem when viewing a thermal photographic shot of a wall, where the wood components showed up as a weak spot, where those walls were insulated with fiberglass. Typically, this allowed air and moisture movement within the wall cavity. Wood when exposed to the elements of moisture, and temperature variables, absorbs the moisture and due to lowering dew points, those studs soaked with moisture froze up and showed as being thermally problematic devices. We will be eliminating air and moisture movement within a wall cavity, which will solve that problem. I’m highly confident that our wall system design when tested for thermal issues, won’t show any difference at a stud location or on the portions of the wall covered with R20 EPS insulation. Science and history have proved that wood left in a dry environment will last for 100’s of years.

Historical problem areas in wood frame typical construction in the world were caused because of air and moisture conditions which are described in this submission.

BOTTOM PLATE PROBLEMS:

An area of major concern for portions of a wall system that rotted or decayed early typically involved wood bottom plate construction components that got damp and were the first part of most construction system failures. This applied to walls built on concrete slabs, and or wood frame subfloors. The design of a wall system as described in these writings, will include the use of a manufactured plate system that will be designed from structurally sound denser plastic components and or will provide a plastic covering or wrap for the bottom plate.

EXTERIOR DESIGN FUNDAMENTAL PROBLEMS ADDRESSED:

Additional areas of concern have been identified where moisture penetrates past the exterior finish (whether it was a siding construction or stucco design) moisture would build up on the back side of the exterior finish causing moisture problems with substrates, plywood, OSB deterioration and or allowing moisture to enter the building envelope. The design of this proposed wall system would eliminate those problems. We can make an allowance for a small set back suggested at 2-4 cm from the exterior of the wall cavity. This would create a separation from the backside of the exterior finish products. Most stucco wire and siding applications are supposed to be nailed or secured to the studs. Those promoting plywood, OSB and other rigid boards as a nailing surface are outside of the building code and will ultimately cause application failure. A dry air space between the exterior finish and the structure of the building envelope would help in providing an air/moisture barrier, as well as provide some additional insulating value. Ventilation holes and or methods may be designed to allow for air and moisture to escape out of the cavity, thereby keeping the building materials from deteriorating from exposure to moisture.

THE DRAWING PICTURED BELOW SHOWS A TYPICAL 2X6 STUD CAVITY.

IT SHOWS THE VARIOUS R VALUES APPLIED TO AIR, EPS BOARD AND GLASS FIBRE

IT SHOWS THE SPLINE LOCATIONS AND SPACES DESIGNED TO CREATE

AIR TIGHT CAVITIES IN EACH STUD CAVITY.

This drawings above show a typical 2x6 wall cavity.

The EPS is set in by ¼” from the exterior, creating a dry air cavity with an R value of 0.9

Exterior finish may not require typical Tyvek wraps. Black building paper may suffice.

Typical 2x6 wall cavity with glass fibre insulation has a R value estimated at R20

This EPS Wall cavity assembled as described using EPS board with an R per inch of thickness of 4.7 Total R value will be.

R-0.9 Dry air ¼” gap from exterior layer to back set the insulation to eliminate any moisture contact with the insulation.
R-15.275 EPS Board, most EPS board manufacturers have developed new boards with higher density up to 40 psi. They also have boards that register a R value of 4.7 per inch of thickness. With the board installed in the cavity projected to be 3.25” produces an R-of 15.275
R8 glass fibre 2”, This glass fibre is installed around the electrical wires, electrical boxes and any plumbing installed in the exterior wall cavity. With the cavity being warm and dry this may present some additional opportunities for plumbing design that saves costs.
The 2" cavity when filled with Foamed in place insulation will have an R value of between 12. and 13, for this presentation we have used 13.

Total R value R-24.175 with Glass fiber, or R 29.175 with Foamed insulation.

These drawings show the location of the cut out for the spline locations of the studs and the top and bottom plates. It is showing a separation of ¾” between the spline locations. The spline and the cut out on the bottom plate will be continuous. the locking splines, which will be glued, and friction fitted in place providing structural values and an airtight cavity.

In an assembled wall there are wood to wood connections, they will be caulked and glued. The plates when the panels are being installed on the construction site will be caulked and glued in place.

PROTECTION FOR BUILDINGS BUILT IN SEISMICALLY ACTIVE AREAS:

Historical problem areas in locations globally that are affected by earthquake or seismic activity.

Besides the structural integrity of a building system being impacted by this kind of shaking activity, it causes settling of loose fill or batt type insulation, which leads to energy losses. A wall system that could withstand minor tremor activity and not be impacted by a loss of insulation and or structural values, would be a desired design criterion. A wall system designed utilizing a building system as described in these specifications would be a preferred design criterion. When developing the wall system 35 years ago we performed shear wall tests to establish values for a 8’x8’ wall panel 16” and 24” on centre construction and to compare to the industry standard. We did have a structural engineer witness and take part in the testing program. At the conclusion of the testing, he was willing to put his engineering stamp on walls designed with our system.

With the new EPS boards available in the industry, we should be able to create a shear wall design that is superior to what we created 35 years ago when we utilized standard EPS block with our system. Many of these new EPS boards have higher R values, which have addressed a multitude of concerns not available 35 years ago. These new boards offer a denser product that can perform better in structural, insulating, and moisture resistance parameters.

PROPRIETARY KNOWLEDGE AND DESIGN.

Portions of that old system did have a patent registered; a copy of the filing is attached to this submission. Any work that will be done to promote this wall system will likely end up being open source. There might be patents (see my comments regarding patents at the end of this presentation) potentially applicable to modified systems, for instance a wall panel system that demonstrates shear wall capacity, or products that will be developed, like dimensional plate components with a flange with fingers designed into it from a molded or extruded manufacturing process, which would be an integral part of a new system helping to lock the EPS in place might be possibilities. Companies like EPS Manufacturers whose main interest is selling EPS, or other plastic design boards or products used in the construction industry, would benefit in a massive way from the development of a wall system as described in this presentation.

SPLINE DESIGN:

My original spline design was an extrusion molded PVC device of a density suitable for the application. It was an intersecting cross design, with flexible angular fingers created on the top and bottom sections that locked into the stud and board insulation locations.

The length of the bottom spline that was pushed and glued into the stud was approximately one quarter of an inch long with the flexible fingers on each side being of sufficient length and thickness and strength to provide stability.

The length of the top spline that was inserted into the EPS was approximately three eighth of an inch in length with flexible angular splines that would contact the EPS board and hold it in place as the glues set up. The horizontal cross section was approximately Three eighth of an inch wide and of sufficient thickness designed to stabilize the spline once it was installed. The forgoing design description size and or use of PVC and or other appropriate components will need to be assessed when designing splines to be used with the various board types. Sizes of the PVC Splines and the saw kerf in wood components to be determined.

EPS BOARD SIZES AND STUD SPACING CONSIDERATIONS:

Once the board sizes are established for standard stud infill, inventories may be created for sixteen- and twenty-four-inch centre construction processes, with standard heights eight-, nine- and ten-foot lengths.

While 16” OC gained in popularity because of problems with exterior applications and or structural concerns, there is a costly waste of wood components that a properly designed 24” spacing would address.

These panels would be prepared with the cutouts created for spline insertion. Inventory of all standard components would facilitate a quick order fill ability.
To offer a bottom plate piece of EPS dimensional material to replace the two by six wood bottom plate pieces. This would present an opportunity to develop a building code allocation for a product designed to replace the traditional dimensional lumber. I described the rational earlier in this presentation. There is a demonstrated need for a durable bottom plate component that won’t be impacted by long term exposure to moisture, there may also be some termite or other bug protection offered with these products.

ADDITIONAL REVENUES COULD BE EARNED BY IMPLEMENTING THE FOLLOWING PRODUCT DESIGNS

Sales of finger jointed 2x6 studs with the saw-kerfs installed.
Sales of various lengths of 2x6 finger jointed wood with saw-kerf installed for cutting to size for top and bottom wall plates.
Sales of EPS with the cutouts for the installation of the vinyl attachment splines. Sizes will be to fit in 16” and 24”OC x standard stud height.
Sales of vinyl splines precut for Stud length.
Sales of vinyl spline in roll for cutting to size for top and bottom plates.
Sales of Glue for treating the EPS for spline insert.
Sales of cases of screws and fasteners
Sales of equipment systems for prefabrication of wall systems, listed below.
Sales of rolls of metal banding for cross bracing of walls if and when required.

ELECTRICAL SYSTEM DESIGN AND WIRING LABOUR ADVANTAGES:

Once the air and vapor integrity of the wall system has been proven, application can be made to the building code for an exception to eliminate the poly-pan product and the tedious installation processes. The labor and material cost savings will be substantial. The purpose of those poly-pans installed around electrical fixtures was to slow down or prevent air and moisture flowing into the interior of the wall system. Our wall system will eliminate that problem.
Other savings will be realized with a simple process of predrilling holes in the studs right from the lumber mills, to accommodate electrical wires. This will have the effect of reducing the cost of wiring and would be well received by the electrical installation trades.
Even a simple thing like the cleanup of the shaving drilling mess created from on site drilling will offer a saving. Those shaving from the drilling being performed at the mills will be used to create other products like OSB, and or other products that can be created from those shavings.

INSULATION TRADE ADVANTAGES:

Additional savings will be realized by the Fiberglass installation contractors.
With the return to 24” OC construction, there may be advantages to utilizing blow-in insulation products and processes that provide a rigid backing once those products solidify and stabilize.
This system utilized three- and one-half inches of EPS or manufactured boards, leaving a two-inch cavity for R8 fiberglass to be installed. That addition of two inches of fiberglass contributed to the bring the R20 rating required at that time. Newer systems of denser EPS boards combined with foamed in place finishes could produce wall systems of R30 or higher.
With some of these newer, denser EPS wall boards providing a R value of 4.7 per inch of thickness, A new wall system inside of that 2x6 stud cavity utilizing three- and one-half inches of the new board at R16.45 and add the R8 glass fiber, could produce or deliver a R24.45 in that same 2x6 cavity. Or as mentioned in the previous paragraph, a wall system of R30. Those systems would represent a huge improvement in energy consumption savings, in either a heating or cooling requirement.
Whether a batted ceiling installation was used, or a blow in type to maximize the insulation in the attic, would be a choice. The labor component of installation of the batt type insulation would be the same, or even less than before, thereby keeping the insulation trade on side.
This is the skilled trade that performs the installation of high grade of poly air/vapour barriers that are still required at those ceiling locations which require insulation, as well as air/vapour barrier protection.
These ceiling locations may provide an opportunity for development of new EPS boards and installation procedures that could replace the poly products and processes that are offered today. While those current products and processes are good, if we are going to last for millennia new products and systems will need to be created.
My original drawing from my patent application is pictured below. Descriptions are provided in the attached patent document.

FRAMERS AND CONSTRUCTION ADVANTAGES:

Speed of construction is the big plus using a prefabricated wall system.

There is a probability of achieving substantial savings on construction labor. The walls for a typical 1,400 square foot rancher can be erected and or stood up in little more than an hour with a four-man crew.
Wall systems delivered with a hoist lift delivery system would also add to labor cost savings.
The exterior wall system with a 2” cavity allows for easy installation of backing where interior walls need to be connected to exterior walls.
There were advantages for the framers in using light weight panel systems. This helped protect workers from injuries generated when attempting to set up heavier prefabricated systems.
We also designed a simple angular wall design for bay windows and other locations requiring angular construction.
These angular insulated sections for bay and bow windows might be an opportunity for design of molded EPS components to suit a variety of angles.
Flanges might also be developed as part of these moldings to accommodate the installation of windows.
Typically, most framers apply the exterior building wraps, like Tyvek and or other types of exterior wraps. The purpose of those wraps is to control air and vapor from impacting the wall system. With our new design which eliminates air and vapour movement into the building environment, applications will be made to building codes for exceptions to the requirements of building wraps. The labor and materials to install those wraps, which are expensive will be eliminated and dramatically reduce costs.
With all of these savings coming from a multitude of areas, it isn’t difficult to see that this prefabricated EPS wall system could end up being cheaper that conventional construction methods.

PLUMBING TRADE ADVANTAGES:

Thirty-five years ago, the plumbers were also OK with installing their vents in exterior locations, with the 2“space available. With the Air/Vapor and insulation integrity on the exterior of where their plumbing was installed, this provided extra protection that their plumbing would never be affected by weather or moisture conditions. By providing a two-inch cavity, which would be warm and dry on the inside of the exterior walls where they may choose to run air vent or fluid filled lines, this option may provide design savings when plumbing is planned.

STRUCTURAL ADVANTAGES:

Even though part nine of the Canadian building code doesn’t call for structural strength in the exterior design of the building envelope, we had demonstrated that our wall system has structural strength with the utilization of my vinyl finger grip designed attachment splines, which were glued, and friction fitted into both the stud and insulation contact points. We had engineered tests showing that we had structural strength, that would stand up to normal earthquake shaking. Our system would fare better in a moderate earthquake response, as the insulation wouldn’t settle, and our wall system was flexible and easily returned to its main location without damage. We had installed our wall system in a 3 ½ story wood frame apartment in Richmond BC. Our engineer certified many buildings designed with our walls.

STRUCTURAL INTEGRITY OF AN EPS WALL SYSTEM WILL BE UPGRADED:

With advances made in the production of EPS boards with improved density increasing its structural integrity, combined with our glued and friction fitted locking splines, will create a wall system that can be measured in a shear wall testing process that will demonstrate that wall panels created with this system will not require a rigid exterior framing. No shiplap, OSB board, plywood, cross bracing or hard board applications will be required to deliver a structurally sound panel, or a completely structurally sound building envelope. Once these structural values have been determined, they will be shared with the consortium.

MOLD AND MOISTURE DAMAGE ISSUES HAVE BEEN SOLVED:

AIR TIGHT - AIR INFILTRATION ALONG WITH MOISTURE ENTERING BUILDING ENVELOPES HAS LED TO A MULTITIUDE OF PROBLEMS GLOBALLY. THE BATTLE FOR ENERGY EFFICIENCY, LED TO MOLD PROBLEMS, WITH THE ATTENDANT HEALTH PROBLEMS AND BUILDING DETERIORATION. WE HAVE CREATED A WALL SYSTEM THAT WILL ELIMINATE AIR INFILTRATION, ELIMINATE MOLD PROBLEMS AND GUARANTEE A SUPER ENERGY EFFICIENT DESIGN. WITHIN EACH STUD CAVITY THERE WILL BE AIR TIGHT INTEGRITY - NO AIR FLOW:

It has been conservatively estimated that in excess of 60% of the buildings in North America and a high percentage of buildings globally have mold problems and have experienced a multitude of problems, including building component deterioration. With the design of our system, each stud cavity provides vapour and airtight integrity. The attachment strips were located at a centre point approximately 2 ¾” on the plate and head structures, and the strips on the studs were located 1 ½” (or a suitable distance) in from the outside location providing 1 ¼” (or a suitable distance) space for the insulation to make full contact at those joints. Refer to the system drawing to help understand how our system is constructed.

RAIN SCREEN EFFECT

For detailed information on how this wall system will create a rain screen effect, contact Dave through contact information below.

Also information will be provided on how our building system will meet or exceed the new building code proposals for both United States and Canada.

WOOD COMPONENTS FOR CONSTRUCTION:

It is recommended to use finger jointed lumber for all standard stud height, ie 8’, 9’ and 10’ high construction requirements. The manufacturing of a better piece of wood that has strength and wouldn’t warp is an huge advantage. The wood could be ordered from the mill with saw kerfs created in both stud and plate materials for the reception of the fingers on the connecting locking strips (typically produced from PVC or other suitable materials). There will probably be advances in plastics that will allow manufactured products to replace wood as durable and affordable alternates.

ADDITIONAL COST SAVINGS GENERATED USING PREFABRICATED SYSTEMS.

FOR ELECTRICAL TRADES:

There will be cost savings passed on from electrical contractors, for a number of reasons.

Not having to drill holes for wire runs in exterior stud locations. Having the studs predrilled for wiring requirements. Two or three horizontally located positions would allow the electricians to find the most efficient and economical path to follow with their wires.
Reduced site cleaning costs.
The future cost savings for not having to install Poly-Pans, and or trying to stop airflow into the building envelope, would represent both a material and labor savings.

INSULATION INSTALLATION SAVINGS:

The time saving of installation of R8 instead of R20 will have to be measured, but there will be a labor savings.
The fiberglass still needs to be tucked in around electrical and plumbing locations, as well as other areas that insulation installers are aware of.
Insulation trades many times also install the interior poly barriers. Once the air and vapor integrity of the wall system is established, application can be made to the building code to modify, change or eliminate the need for interior poly barriers, or at least eliminate the need to glue or chalk them in place. They could go back to using a T5 tacker to install the poly, whose primary function might now be to keep the fiberglass insulation in place while sheet rock/Gyproc is installed.
There should be a reduction in labor and materials when installing two mil barriers instead of the heavier six mil barriers.
The installation of the two-mil barrier will have its performance requirement reduced to a product that will be holding the R8 fiberglass in place while sheetrock is being installed.
Another option to eliminate poly barrier, might be to foam the two inch space with modern foam insulations. Cost versus performance evaluations will need to be made.
The two-mil barrier won’t have to be caulked in place as the air barrier is integral within the wall panel.
Ceiling protection and design is mentioned elsewhere in this presentation.

SHEET ROCK/GYPROC INSTALLATION SAVINGS:

There have been a variety of installation procedures for sheetrock that required gluing or chalking the board to the studs. This process will no longer be required, as the need to stop air flow will have been dealt with by our exterior insulated wall system with air/vapour barrier in place.
There may be an opportunity to develop an EPS board system to replace sheetrock on ceiling applications that would require air/vapour/insulation properties. This would be different from the recommendations regarding replacement of the poly barrier.

CONSTRUCTION WASTE REMOVAL COST SAVINGS:

It is a proven concept that prefabricate systems reduce waste removal costs. Defining that number in terms of a % of costs, should be able to be identified.

SPEED OF CONSTRUCTION FINANCE COST SAVINGS:

Each day saved for a contractor builder who is delivering 100’s of houses a year represents major financial savings. Five to six days saved on a typical house multiplied by 100 houses could represent, thousand of dollars in finance or borrowing costs.

EQUIPMENT SYSTEMS FOR ASSEMBLY OF WALLS:

Framing tables will be designed with both wood and metal materials in mind. Sizes to be determined. Our original system thirty-five years ago utilized a hydraulic compression system on a full-sized steel table set up for that assembly process. That table and process was expensive and will be replaced by a simplified overhead air over hydraulic screw threaded device. One of these devices at the header and one at the plate location will only need to expand to a thirty-inch maximum. There will be an operator at both positions. Once each stud has been compressed onto the locking spline, the top and bottom plates can be partially screwed in place to hold them loosely secure as the next stud and EPS sheet is set loosely in place for the next compression action. The final process for installers on the head and foot locations will be to tighten the top and bottom plates to the stud locations to finalize the wall assembly. It may prove to be more advantageous to assemble the total length of the wall assembly before applying the top and bottom plates.

Prefabricating companies already in business may be able to utilize some of their existing equipment.
Companies already offering prefab systems my be interested in a low-cost energy efficient option.
High speed hydraulic screw type devise will provide the compression strength to set the locking splines in the studs in place forcing the EPS sections to lock in place.
The attachment of the top and bottom plates will likely be performed with manually operate screw guns securing the plates at all stud locations.
With the light weight of the wall sections, most will be manually moved without overhead hoists required.
If diagonal metal banding is required for structural reasons, the walls could easily be stood in place off the table, checked for square and the banding could be installed with either nail or screw attachments as required.
There is a potential for sophisticated design and assembly tools and processes. Ultimately CAD and Semi or Fully automated assembly systems will be developed. Our imaginations are our only limitations.

EQUIPMENT FOR WALL ASSEMBLY:

EPS will be sold with the standard cut out or burn outs or cavities preprepared for the inserting of the locking splines. For the locations that require custom widths, Mobile EPS wire burning stations. A heated wire 8’ in length will be used to burn out or remove a section of the EPS panel where it will provide a receiving location for the vinyl joining strip. There will be a standard height location for setting the wire for the stud lengths.
There will be a second wire 30” wide for the removal of WPS for the plate and header strips to fit into. This machine will be capable of servicing 16”– 24” OC panels
There will be a glue wheel bath or glue application system for applying a bead of glue to the EPS locations where the attachment strips will make contact.
Glue guns with hoses, pressured with glue will be available to provide a bead of glue for remote applications of glue where required.
Standard air nailing guns and screw guns will be required. Low root screws of various lengths will be specified for the different applications.
A Table saw for running saw kerfs in various lengths of studs and plate materials.
Radial arm saws for cutting wood components to length.
Hand trucks and floor jacks for moving pallets of materials, as well as to move wall panels.

LONG TERM BUSINESS PLANING TO MAXIMIZE EPS PLANT CAPACITIES:

There may be products and or processes produced as described in other location in this presentation. Those devices or processes may replace or be identified as equivalent to existing products or processes. Like manufacturing a product that could replace dimensional lumber for use as bottom plate materials in wall system design. The background of deterioration of wall systems over the years has shown one of the weaker components of any wall system is the bottom plate of the wall that rests on a concrete slab or other floor or subfloor construction methodologies. Contact us to see how we envision a plate material to replace wood.

NEW STRUCTURAL EPS BOARD WILL BE TESTED TO SHOW HOW THEY COMPARE TO PLYWOOD SHEETED WALL SYSTEMS:

Utilizing standard EPS board 35 years ago we were able to establish shear-wall values sufficient to have a structural engineer agree to stamp plans that utilized our wall system. We built a three- and one-half story wood framed apartment that our engineer was willing to stamp as structurally sound. We also sold several townhouse projects that utilized our system. In addition, we were able to sell and produce hundreds of single-family structures, as well as some commercial warehouses, and some poultry growing structures. These areas of the construction industry could certainly use a wall system with structural and air/vapor strengths, also a system with vapour resistance designed into the system.

It would be desirable for interested companies to have a structural engineer under contract or on retainer in the design stages. It would be critical for the long-term planning to work a liaison with the construction industry as well as the building code governing bodies. It is our plan to have one of our team members dedicated to coordinating working with those bodies.

Our team can help co-ordinating these processes and regulation approvals globally. What will be good for one can be developed for the benefit of all. A dynamic process of sharing and co-operating will prove to be the best and most desired process.

With the advancement of new generation of wall board with additional structural values built into your panels, would when used in conjunction with this wall design with the spline system glued and or friction fitted in place, should provide a shear-wall design that could generate a building code allowance or modification for use of the board as part of an engineered wall system.

There will likely be room for developing exterior wall finish products like lap or horizontal sidings produced from EPS components. The same opportunity will be available for design of roofing products and systems that will last for millennia.

Prior to our company closing, we were close to making applications to the building code in Canada for approval of our wall system with both structural and air-vapor barrier integral within the design. That aspect combined with the structural integrity of a designed system would put an EPS manufacturer in a prime position in the market, allowing them to obtain premium values for their products.
