Questions and answers
- When does Johns Manville insulation go on sale?
- Johns Manville does not run its own consumer sales; pricing is set by retailers. Insulation discounts cluster around spring and fall weatherization promotions and store contractor events. Watch the price history on each product page for the real low.
- Where is Johns Manville insulation cheapest?
- Home centers and lumber yards usually beat hardware stores on R-13 rolls, and multi-pack or pallet pricing lowers the per-square-foot cost. Compare the price per square foot, not the pack price, since roll coverage varies.
- What are Johns Manville's best-known products?
- Fiberglass building insulation, especially kraft faced rolls for walls and batts for attics, plus commercial roofing and mechanical insulation. R-13 kraft faced is the standard choice for 2x4 exterior walls.
- What is the return policy on Johns Manville products?
- Returns are handled by the store that sold the insulation, not by Johns Manville. Keep the receipt and check the retailer's window, since opened insulation packs are often non-returnable.
