All-in-One Mega Panels

The Next Generation of Construction.
Sheeting, joists, studs, trusses are combined in one solid panel, up to 4’ x 24’ widths. With everything built right in, panels are ready to use, with no pre-framing required, making installation simple and faster. Electrical raceways are also conveniently integrated.

Superior Value

Panels are built in a state-of-the-art manufacturing facility which controls quality and costs. Although per-panel costs are higher than conventional materials, overall job costs are significantly reduced by eliminating multiple construction steps and the additional labor to complete them.

Good for the Environment

Made of wood products and high-density expanded polystyrene, all materials can be recycled. Sustainable practices are used in manufacturing OSB that include renewing wood resources, respecting forestry through maintaining water quality, wildlife habitats and soil productivity and minimizing and recycling waste. EPS is recognized for its low impact on the environment in areas such as climate change, stratospheric ozone depletion, ecotoxicity and fossil fuel depletion.

Good for your Health

Compared to standard insulation materials such as fiberglass, ISO foam and cellulose, expanded polystyrene (EPS) is the Health Smart choice. It is solid, nonporous and moisture resistant, preventing mold and insect infestation. Unlike fiberglass, EPS will not release carcinogens through fiber emissions that carry the risk of potentially serious respiratory and other health conditions. Compared to ISO foam, EPS also will not out gas toxins, such as formaldehyde. EPS provides no danger to humans during manufacturing or in handling during construction.

Green – Saves Energy

The panel’s integrated EPS insulation core creates a 100% thermal barrier, effectively blocking cold-air infiltration into the home and heat transfer. From the inside, your conditioned air is blocked from escaping. Both functions provide significant energy savings without reduction of performance over time.

A coffee cup is only 1/16″ thick and you can hold water in it that is over 200 degrees. Imagine the thermal protection from a wall 96x thicker!

Energy Star Performance

As one of the best performing insulators known, EPS is made of material similar to a Styrofoam cup – at just 1/16” your hand is protected from 200-degree coffee. Our standard 6” panel contains EPS that is 96 times thicker than a coffee cup for a 100% thermal barrier, meeting stringent Energy Star standards. Our 8“ panel is 128 times thicker!

Excellent R-Values.

8” roof panel: R-value 31.6 with a 100% thermal barrier; 6” wall and deck panel: R-value 24.3 with a 100% thermal barrier. Unlike fiberglass, ISO foam and cellulose, EPS won’t shrink, absorb or retain moisture which reduces R-values and thermal performance.
