Traditional framing makes buildings vulnerable to energy loss. Walls and ceilings of a conventionally constructed building can contain thousands of cavities, and each must be adequately insulated to stop air flow. Any imperfection and energy loss is sure to occur.

A building's wood frame also conducts heat readily, from its interior to exterior and vice versa, via thermal bridging. Studs and rafters act like a heat pump, slowly but surely robbing the building of energy.

SIPs solve the air leakage, infiltration and thermal bridging issues that plague traditional wood-frame construction. The cavity is filled with solid EPS that's permanently adhered to the OSB facing. Because there is no wood member between the inner and outer OSB, a SIP offers little to no surface area for heat conduction.

Through testing and real world experience, SIPs have been consistently proven to reduce heating and cooling requirements by 50% or more.

When properly installed and sealed, R-Control SIPs substantially reduce air infiltration into a building or home. Tests by the DOE's Oak Ridge National Laboratory indicate that a room with four-inch SIP walls had 90% less air leakage than an identical room with 2x6 studs.

This reduces energy consumption over the life of the building. Since air exchange rate is an important determinant of HVAC loads, there's also an opportunity to save money up front by reducing the size of HVAC systems.

To capture the full value that SIPs provide, it's important to use a data-based, analytical approach to HVAC sizing. The tendency is to oversize the system "just in case." Not only does this cost the owner more at the outset, it picks their pocket with every heat bill, because an oversized system is less efficient than one that's sized "just right."

R-Control SIPs are made from high-quality, engineered OSB and rigid EPS insulation cut to close tolerances.

They're manufactured under controlled conditions, and inspected for compliance to standards and job specs before they leave the plant. Every panel is marked with the PFS quality seal.

Using R-Control SIPs introduces a level of consistency and reliability that cannot be achieved when framing with dimensional lumber and building onsite. They're straighter when installed and, unlike dimensional lumber, will not warp or buckle over time and under load.
