Get Numerous Benefits

Structural Insulated Panels (SIPs) have become popular in the construction industry due to their numerous benefits. They are a cost-effective and energy-efficient construction system that can save labor, time, and cost. Our SIPs offer superior insulation and air sealing capabilities, which can lead to significant energy savings over time.

Various Applications

SIPs suit various residential and commercial building applications, including walls, roofs and floors. These high-quality foam core panels are solid, one-piece structural components with exceptional strength and durability. Each panel is made of an Expanded Polystyrene (EPS) core, bonded between two outer layers of rugged Oriented Strand Board (OSB), creating a robust and reliable building material. You can visit the 'Best Application for SIP's' page for more details.

Expanded Polystyrene Foam Core

EPS is an inert, stable cellular plastic with superior insulating qualities. Unlike many other foam products, EPS is "ozone-friendly" - no CFCs or HCFCs are used to produce panels. Other characteristics of EPS include:

  • Structural Integrity: EPS retains its shape indefinitely. It will not shrink, decompose or disintegrate due to age or weather.
  • Thermal Stability: The insulating value of EPS does not decrease with age.
  • Toxicity: EPS is formaldehyde-free.
  • Low Water Absorption: EPS has a closed-cell structure. Its water absorption level is so low that moisture and the elements will not significantly affect its insulation values.

Exterior and Interior Skins

The oriented strand board skins on structural panels are exterior-rated Exposure I, certified by the American Plywood Association (APA).

Energy Efficiency & Comfort

At American Structural Insulated Panels Systems, we know that Structural Insulated Panels (SIPs) are highly effective in reducing heating and cooling costs. Our SIPs form a solid thermal envelope around the structure, which is uninterrupted by typical studs, sills, or headers, substantially reducing air infiltration compared to conventional construction techniques.

Moreover, the solid insulation core in our SIPs eliminates the convection looping that can occur in gaps and spaces typical in batt insulation. Our SIPs provide even more significant energy savings than the high R-rating suggests.

Nailbase Panels (Timber Frame and Retrofit Panels)

Nailbase panels offer a simple and effective way to enhance the energy efficiency of older homes. These composite panels consist of rigid insulating foam bonded to a single sheet of oriented strand board (OSB) structural sheathing. They can be installed over timber frame posts and beams, cut to size on-site, and installed directly over existing wall and roof sheathing for retrofit projects. This provides additional insulation without disturbing the home's interior.

Once installed, new cladding can be attached directly to the OSB face, serving as the fastening surface for siding or roofing. Nailbase panels are an excellent option for homeowners looking to incorporate energy conservation measures into their home renovation projects.

Advantages of Using Nailbase Panels

  • Various sizes to match design needs
  • Multiple options for substrate and foam
  • Select core type and thickness to match your performance needs
  • The outside installation allows better performance, faster installation, and no disruption of existing wall assemblies, insulation, or mechanical
  • Detailed in minimizing thermal bridges and air infiltration
  • Assembly details that require minimal training

Calculate the Total Wall Area:

Accurate measurement of the length and height of each wall is essential to determine the total wall area. Multiply the length and height of each wall to obtain the individual wall area. Sum up the areas of all the walls to calculate the total wall area.

Calculate the Total Roof Area:

Calculate the total roof area by multiplying the diagonal distance times the ridge length and adding all roof areas together.

  • Include all overhangs in your calculation
  • Round all dimensions up to the nearest even foot

Wall Area + Roof Area = Total Panel Square Feet:

Once you have calculated the total wall area and total roof area separately, combine them by adding the wall area to the roof area. This calculation will provide you with the total panel square footage required for your project. It serves as a valuable guide in determining the appropriate quantity of Structural Insulated Panels needed for installation.

Please ensure precise measurements for accurate calculations, allowing us to deliver the ideal SIP solutions tailored to your project's specifications.

Our cost estimate formula provides a quick and easy way to calculate a rough estimate during the planning phase of your project. These calculations are based on averages, and individual designs will vary depending on style, location, and panel usage.

This calculation below is based on an average size structure (1,800 - 3,000 sq. ft. of living space). It is important to note that these figures should not be used for additions as project costs can vary significantly due to site location, access, proximity to equipment and lumberyards, time of year, and project complexity.

1. Calculate the total wall area by multiplying the length of the wall times its height and adding all wall groups together.

  • Do not subtract for window or door openings
  • Round all dimensions up to the nearest foot

2. Calculate the total roof area by multiplying the diagonal distance times the ridge length and adding all roof areas together.

  • Include all overhangs in your calculation
  • Round all dimensions up to the nearest even foot

3. Wall area + Roof area = Total Panel Square Feet

For the material cost, multiply the total panel area by $15.00(due to volatility in the building materials market, this price can vary based on current commodity pricing).

This calculation provides 4 1/2" wall panels and 8 1/4" roof panels. For thicker panels add $1.00 per square foot for each increase in thickness; for example, 6 1/2" walls and 10 1/4" roofs would be $16.00 per square foot.

This price is only for quick estimating purposes. The cost may be less based on the design of the structure and the optimization of the panel cutting. The panels can be as large as 8ft x 24ft.
