The attic stair opening is the largest gap in home insulation, increasing heat loss in the winter and heat gain in the summer. Made of durable dust-free expanded polystyrene foam, the Draft Cap will reduce heat loss and heat gain and help you save on your heating and cooling bills.
Lightweight and easily installed in less than 5 minutes, the Draft Cap attic stair insulator satisfies all current energy building codes for insulation over the attic access panel with an R-value of +11.
DraftCap can now be compatible with the new R-38 code requirement. More information Coming Soon

R-value: R means resistance to heat flow. The higher the R-value, the greater the insulating value.
