Frost King products: prices and price history
Questions and answers
- When does Frost King go on sale?
- Frost King discounts cluster in fall and early winter, when stores push weatherstripping and window kits, and again in spring for window and door sealing. Hardware chains also clear it out at the end of the heating season. There are no live deals on this page right now.
- Where is Frost King cheapest?
- Home centers and hardware stores usually beat hardware-store online listings on Frost King foam, and multi-packs lower the per-foot cost. Compare the roll length and thickness, since Frost King sells similar-looking foam at different densities and prices.
- What is Frost King best known for?
- Weatherstripping and window insulation kits are its core. The self-adhesive foam products here suit draft sealing around windows, doors, outlets and pipes; the foil-faced version adds a radiant barrier, and the closed-cell sheet resists moisture better than open-cell foam.
- Can I return Frost King insulation?
- Returns follow the store's policy, not Frost King's, so check the retailer's window and whether opened rolls qualify. Unopened packages are the safest to return; cut or installed foam usually is not accepted.
