ESS has 2 different kits that fit virtually over any side wall panel (sometimes also called knee wall doors). Each has a lid that creates a tension based air tight seal. Each kit has an R-24 insulating value, tight air seal and 20 year warranty. Kits come with a handle for use when opening and closing the lid.

For a side wall panel, take the following measurement:

A) Length and width of opening

If A) is less than 36 x 36 inches, then you need a standard side wall kit
