Kits are made of rigid foam panels that fit into a foam frame to form an air-tight seal.
Shown here is the kit for attic space accessed by a pull-down ladder. Kits for push-up hatches, stairway and knee-wall entrances are also available.
When you want to get into the attic, the light-weight panels can be easily lifted. The heaviest kit component weighs just 10 pounds.
Ceiling kits have an R-39 insulating value, while side panels are R-24. R-value is a measurement of resistance to air-flow; the higher the R-value, the greater the insulation.
The kit is backed by a 20-year warranty. The company's website has detailed measuring and ordering instructions.
