Each panel is a sandwich design utilizing 26 gauge steel on both sides with a layer of baked on, high density polyurethane foam which is CFC free, environmentally friendly and contains a built in fire retardant making the panels extremely durable, strong, fire resistant and their light weight design (2.5 – 3 lb. per sq. ft.) vs traditional lumber homes (20 lbs. per sq. ft.) ideal for fast, easy construction.

  • Mold Resistant
  • Termite Resistant (nothing for them to eat)
  • 90% - 100% wood free construction (our homes using about 6 scrap cars vs 1 – 2 acres of trees)
  • Light weight
  • Cost effective (less than conventional methods)
Why use your SIP?  
It provides a superior energy envelope that will save you money in heating and cooling costs.  The panel is mold, fire, rodent and water resistant.

Is the panel structural?
 When the panel is combined with our steel connectors to form walls and roof attachment it is extremely strong and structural.  In commercial applications the panel is applied as a cladding.

What is required when building?
When building with our panel method, panels are erected joining one another and the roof all together.  We recommend that a stud wall be erected to provide wiring and plumbing access however they are not necessary to the build.   No insulation, vapor barrier, ty-par or plywood exterior sheeting is required, also, when using the panel on the roof, no trusses are required and the panel itself forms a superior roof that requires no shingles.  Many homeowners leave the panel exterior as it comes in various colors direct from the factory.  Others choose to add brick, siding stone or stucco…the panel will accept any finish, both interior and exterior.

What are the advantages to building with the panel?
Initially the roof goes up fast, usually in a day or two.  This provides you a complete, secure building, free from theft, weather etc.    The panels are about 15% the weight of conventional building methods…so a couple of men in a work crew can assemble a whole home in a matter of hours.
Doors, windows and service openings are cut out after the walls and roof are erected, any size windows or doors will work when building with the panel.

What is the weight and R-Value of the panels?
Panels weigh about 2.75 lbs per sq.ft.  The come in lengths 5’ to 52’ long and widths 36” to 42”.  Panels connect in a male/female method and are secured both top and bottom with steel tracking.
Panels are 2, 3, 4, 5 and 6” thick and for every one inch there is an R-value of 7+.   A typical 3” panel would have an R-value of + R22

What is the filling of the panel?
Each panel is typically 26 gauge galvanized steel on either side, with a baked on painted finish.  The filling is high density poly-urethane foam that is baked into the panel at the factory.  Glues and adhesives are added to the foam along with fire retardants.  The adhesion is extremely strong. 
Panels will not expand or contract due to their design and they provide a thermal barrier.

Can panels be used below grade?
Yes.  We are currently installing basements using the panels and supporting stud walls.  This provides a superior basement, heights to 9’+ is no problem as well, using a 5” panel would give you an R35+ basement wall.
Typical concrete poured basement walls are R-2.   We recommend that if you are planning on using the panels below grade that you speak with us for all the engineer and design requirements.
