Why Therma-Dome® Products?

#

The Therma-Dome line of products are designed to help keep your home as energy-efficient and as comfortable as possible throughout the entire year.

In the cold weather, your energy dollars go to heat the living space of your home, yet gaps in the thermal barrier between your home and your attic can allow that heated air to escape. This warm air passing through the attic can contribute to damaging conditions such as condensation buildup in your attic as the escaping conditioned air meets unconditioned air, or the formation of ice dams on your roof in the winter as heat escapes from your living space through the attic.

All of our products are proudly

Made in the USA
using
US-Made components

As the heated air rises, it pulls unconditioned (cold) air into the living space from the outside. This is known as the "stack" or "chimney" effect. In the summer, the effect is reversed, as hot air from the attic forces its way down through gaps in your thermal barrier, pushing your cooler (conditioned) air out.

Insulation, by itself, does not constitute an effective thermal barrier. The boundary between the conditioned living space and any unconditioned space must also be sealed to prevent airflow.

Therma-Dome products are designed to close gaps in that thermal barrier, not just insulating these voids in your home's insulation envelope, but sealing them. Each Therma-Dome kit is constructed of polyisocyanurate foam board, sandwiched between layers of reflective foil. The polyiso material is a lightweight yet very efficient insulator. Therma-Dome products are the only products on the market to offer both significant insulation and an air-tight seal, using continuous Q-Lon® brand* foam-core gasket and VELCRO® brand fasteners.
