Double Sided Aluminum Foil Insulation consists of two layers of durable aluminum foil, bonded together with a heat-resistant adhesive. The reflective properties of the aluminum foil work by reflecting radiant heat away from the insulated space, preventing excessive heat transfer. In hot climates, it helps keep interiors cool, while in colder environments, it retains heat, creating a more comfortable indoor climate and reducing the need for heating and cooling systems.
This insulation aluminum foil also serves as an effective vapor barrier. It prevents moisture from penetrating the insulation, reducing the risk of condensation and mold growth, which can damage the structure and degrade indoor air quality. As a result, this insulation material not only enhances thermal performance but also protects building structures from moisture-related issues.
