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