Insulated building panels, sometimes called structural insulated panels or SIPs, are made up of a rigid foam core that is then surrounded by outer skins, usually strand board or another such material. They can be used in place of standard stick-built frames and roofs for homes and can usually be installed faster than standard frames so your construction time is much shorter when you use SIPs. 

If you're thinking about using insulated building panels, either for a new home construction or just for a remodeling, note a few questions you might have about SIPS. Discuss the option with a contractor to see if it's right for your home.

Why is the HVAC system different with SIPs?

If you choose structural insulated panels or insulated roof panels, you may note that your contractor recommends a smaller HVAC system for your home, meaning the furnace, air conditioning, and ductwork. This is because these panels usually do a much better job of insulating your home than standard fiberglass insulation or blown foam set between a stick frame. In turn, you can use a smaller HVAC system and not need to have such large ductwork in the home for blowing hot or cold air through the structure. This can save you money on the HVAC system and on your utility bills throughout the year. 

Are SIPs compatible with other building materials?

You can install SIPs with a concrete foundation or add insulated roof panels to your existing stick frame home. They are made so that a contractor or builder can attach them to the outer frame of an existing home with the right bolts and connectors. This allows you to add insulated panels to the roof of your home without worrying about the material of your home's frame or thinking that you need some type of special foundation for using SIPs for your home's entire construction. 

Can SIPs be installed with any construction materials?

While these panels are compatible with other building materials, they do require their own materials for construction. The joints need to be sealed with compounds made especially for these panels so they don't detach from one another. Expanding foam sealant can be used as well as this will fill in those areas and keep them secure. If you have some experience in construction and want to consider installing your own insulated roofing panels, be sure you understand how to seal the joints of the panels so you get an airtight fit.
