Structural or steel insulated panels (SIPs) are used in the construction of commercial and residential structures and buildings. They can be used in roofs, walls, floors and other structures. SIPs are typically made of oriented strand board (OSB) panels with Polyurethane foam or rigid foam plastic insulation sandwiched between them. They’re high performance and known for their energy efficiency, lightweight, durability and cost-effectiveness.
Below are answers to some common questions about SIPs and their many benefits:
Are the Panels Mold and Mildew-Resistant?
Structural insulated panels are mold and mildew-resistant by design, and can be used to build structures with the same properties. SIPs are free of cavities, so there’s nowhere for moisture to build up on the panels. This essentially makes them mold and mildew-resistant. When constructed properly, SIPs create airtight seals and structures that prevent moisture infiltration and build up. Without a moist environment, mold and mildew can’t grow.
Are SIPs Fire-Resistant?
SIPs have a high fire rating, but they’re not completely fire-resistant, especially when applied to wood frame buildings. However, the application of a fire-resistant thermal barrier can make them more fire-resistant than any other building material. Fire-resistant barriers are typically gypsum board applied to the interior of SIP structures, including walls, roofs and temporary commercial structures.
Do SIPs Improve Indoor Air Quality (IAQ)?
Since steel insulated panels form airtight seals, they prevent air from entering and exiting a building. This makes it easier to create a controlled indoor environment. A controlled environment allows you to manage the humidity and amount of air entering and leaving your home. This can create the highest IAQ and healthiest indoor environment. SIPs also limit air exchange to ventilation systems, filtering and dehumidifying incoming air. The process eliminates dust mites, mold spores and other allergens, which can improve IAQ even more.
Do SIPs Work with other Types of Building Systems?
Most builders use SIPs with different building systems because they’re very compatible. For example, SIP wall or roof panels can be applied to wood, insulated or poured concrete foundations. SIPs are also sized to fit seamlessly to dimensional lumber and stick framing. High energy-efficiency properties also make them perfect for insulating timber-framed buildings.
