Insulation supply for Illinois contractors, direct and wholesale.

Illinois winters are unforgiving. Prestige Insulation delivers specification-grade fiberglass batts and mineral wool across Illinois — from Chicago metro to downstate projects — with confirmed lead times and no retail markups.

What Illinois projects need.

Illinois is in IECC Climate Zones 5–6. Chicago-area projects commonly specify R-20 to R-21 in exterior walls and R-49 in attic assemblies. Our SAFB mineral wool is a preferred choice for Chicago multi-family sound and fire assemblies.
