Where to Purchase Therma-Dome


Therma-Dome cover


The One and Only

Therma-Dome® has become a benchmark in the insulating and weatherization industry in the almost 30 years since the Pull-Down Attic stair Cover has been introduced. We recognize that, in some areas, “Therma-Dome” and “T-Dome” have turned into a generic reference to attic stair insulating covers, including many products that do not perform to the level to which we have designed our products to perform. We use only top-quality brand-name components in the construction of our products. It is our desire to keep the Therma-Dome brand synonymous with the quality that we strive for.

Please be sure to ask your insulation contractor or distributor for the original  Therma-Dome brand insulating covers
by Yankee Insulation Products.
Therma-Dome products are available through various insulation and weatherization products distributors nationwide.
