Structural Insulated Panels

ProWall supplies professional grade EPS products to manufacturers of SIPs -- structural insulated panels -- used to build some of the most environmentally sound structures being constructed today.

As a supplier to the industry, we are pleased to be part of an innovative solution to creating dwellings with low energy consumption.

A panel comes off the assembly line at a Phoenix-area manufacturer of SIP products. The sandwich of OSB and EPS foam creates a strong wall structure with a high insulating value. Wire chases are pre-engineered into the product.

SIPs are used to build walls, floors and roofs. Each tongue-and-groove panel is designed to be assembled with grabber screws or ringshanks nails on site. The result is extremely strong structure with extraordinary insulation values.

Energy Stars

Using structural insulated panels (SIPs) in residential building can easily qualify a home as Energy Star. A SIP building envelope has an extremely high whole wall R-Value and low levels of air infiltration, reducing the overall loads for heating or air conditioning equipment in the home

Workers prepare to bond OSB to a sheet of EPS foam produced by ProWall.

SIPs are manufactured to tight tolerances with factory precision, which allows for fast assembly on job sites. Building with structural insulated panels (SIPs) can cut home energy consumption by up to 50%, making it easy to reach Energy Star qualifications with SIP homes.

Green Building

SIPs provide high density foam insulation consistently and flawlessly, without the voids, gaps, and compression of insulation in stud walls. Studies done by Oak Ridge National Laboratory (ORNL) show that when whole wall R-Value is measured, SIPs far outperform wood framed walls. By eliminating the loss of heating and cooling energy through gaps in the insulation, SIPs dramatically reduce the amount of energy used to heat and cool a home.

This 6,000 square foot house was constructed entirely of structural insulated panels that were assembled on the job site. Not only are the walls superinsulated, they reduce construction labor costs and speed up building timetables.
