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.
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.
Kraft-faced and unfaced batts in standard and high-density grades. Available in R-11 through R-49 across all widths. ASTM C665-compliant.
AFB and SAFB mineral wool for walls, floors, and sound-party assemblies. Non-combustible, moisture-resistant, and dimensionally stable.
Wholesale pricing on every order. What you see on the quote is what's on the invoice — no retail upcharges or hidden fees.
Submit a request and we respond the same business day with availability, pricing, and a confirmed delivery window to Illinois.
Direct contact with the supplier. No call centers, no ticket systems — a direct line to the people managing your order.
