Aluma-Foil is made of two layers of a 100% pure aluminum, laminated with a non-toxic adhesive, to both sides of a heavyweight , natural kraft paper. Aluma-Foil is a very durable product and yet about the same thickness as the cover of a phone book. BecauseAluma-Foil is a vapor retarder, it should be installed like any other vapor retarder ( consult manufacturer or contractor for further details) and all seams and penetrations should be taped ( we recommend Polyken 337 foil tape).

Aluma-Foil is available in two widths:

  1. 25.5" x 235.29 lineal feet (500 sq. ft. rolls)

Where else can I use Aluma-Foil?

You can use Aluma-Foil as an underlayment or in an exposed installation if necessary. It can be used virtually anywhere there is a need to block out toxic vapors from offgassing products, such as insulating materials polystyrene, polybutylene, polyethylene, particle board, plywood, OSB board, laminates, paint finishes, etc..

How do I know that this product will work?

As you know, the degree of chemical sensitivity varies from individual to individual. However, in over ten years and over one million sq. ft. sold, of both Insul-Foil and Aluma-Foil (Same-Product), we have yet to have a complaint or material returned for non-performance.

Is this a product I can install myself?

The answer is yes. Our Aluma-Foil product comes in very manageable size rolls but, when taking on a large job you might want to consider using a licensed contractor. When building a new home or remodeling, remember to have your architect specify AFSAluma-Foil.

Is this a durable product?

Aluma-Foil is very durable and is made with only high quality materials, but because it is made with aluminum foil it may wear rather quickly when used in high traffic areas.
