Structural insulated panels have the ability to insulate as
well as SUPPORT WEIGHT.
Explanation:
- Structural insulated panels (SIPs) are a high performance building system for residential and light commercial construction.
- SIPs are engineered panels used to construct walls, floors, and ceilings.
- SIPs provide an extremely durable, strong, and energy-efficient building option. This is a replacement for construction methods using traditional framing lumber and insulation,
- The panels consist of an insulating foam core sandwiched between two structural facings, typically oriented strand board. The panels also have the capacity to support heavy weights as well as light weights.
- SIPs are manufactured under factory controlled conditions and can be fabricated to fit nearly any building design. The result is a building system that is extremely strong, energy efficient and cost effective.
- Building with SIPs will save you time, money and labor.
