Basement Insulation

Installing EcoFoil Bubble Insulation as a basement wall insulation will keep your basement warmer by insulating the walls and ceilings from radiant heat transfer. EcoFoil Bubble Insulation is also an impermeable vapor barrier that will keep your basement dry and prevent condensation when all seams are taped. 

Without a separate vapor barrier, the warm moist air in your basement will migrate to the cold concrete wall surface and moisture will condense. A much better option for insulation of basement walls is to install a layer of extruded polystyrene (XPS) or some other rigid foam directly to the concrete wall. However, even with XPS rigid foam board insulation for basement walls, you may still have a moisture problem because any polystyrene under 1-1/2" thickness is not considered impermeable enough to be a vapor barrier. The exact perm ratings for any insulation product will vary so you should consult with the insulation manufacturer before purchasing a basement wall vapor barrier.

A "perm", also referred to as a permeability rating is the unit of measurement used to characterize the water vapor permeance of any building material, like insulation. There are several classes of vapor retarders, but according to ASTM E-96, a Class 1 Vapor Retarder has a perm rating of 0.1 or less. All EcoFoil Bubble Insulation products have a permeability rating of 0.02 - thus making them superior Class 1 Vapor Retarders and an approved basement wall vapor barrier.

Insulation for basement walls can differ depending on your climate zone. EcoFoil Bubble Insulation is excellent for insulating concrete basement walls and works especially well when combined with a foam insulation and a dead air space on one side of the product.
