Rigid Insulation Resources

Insulation is a critical feature of any structure. It’s impact ranges from overall comfort to maintaining a uniform temperature. At Insulation Supply we provide builders and buyers with a great variety of rigid insulation solutions to meet those needs. As we all know, every building is different. Circumstances such as architecture, regional climate and building codes combine to create a a unique set of factors for every situation. We meet that demand with an impressive range of high-performance insulation board solutions.

Choosing an R Value

Choosing the right amount of insulation for your home is paramount. By creating an effective barrier between internal and external you can save big on energy bills. Use our suggested R Value Zone Map, provided by the U.S. Department of Energy, to see what’s necessary for maintaining a comfortable house.


Redeem Your Tax Credit

Thanks to the Federal Government you can receive an energy tax credit for adding insulation to pre-existing structures like your house! Reducing the exchange of heat means a smaller heating/cooling bill, as well as few extra bills from Uncle Sam. Find out how to receive your rebate below.

**R-value means resistance to heat flow. The higher the R-value the greater the insulating power.
†As manufactured, Fiberglass insulation is resistant to mold growth. However, mold growth can occur on building materials, including insulation, when it becomes contaminated with organic material and when water is present. To avoid mold growth on Fiberglas™ insulation, remove any water that has accumulated and correct or repair the source of the water as soon as possible. Insulation that has become wet should be inspected for evidence of residual moisture and contamination, and any insulation that is contaminated should be promptly removed and replaced.
