DFC-101A
Double sided aluminum foil insulation is a type of insulation material that consists of two layers of aluminum foil with a layer of insulation material sandwiched in between. It is commonly used in construction and building applications to provide thermal insulation and moisture barrier properties.
Double sided aluminum foil insulation is made of two layers of aluminum foil bonded together with a heat-resistant adhesive. The two layers of aluminum foil act as reflective surfaces, reflecting radiant heat away from the insulated space. This helps to reduce heat transfer through radiation, keeping the interior space cooler in hot climates or warmer in cold climates, which can significantly reduce cooling and heating costs.
The aluminum foil also acts as a vapor barrier, preventing moisture from penetrating the insulation and causing damage to the building structure. This helps in preventing condensation, which can be detrimental to structural elements and can lead to mold growth.
Double sided aluminum foil insulation is lightweight, easy to install, and offers good thermal performance. It is an effective solution for improving energy efficiency and creating a comfortable indoor environment.
1. Attic insulation: It can be installed in the attic to prevent heat gain or loss, improving energy efficiency and reducing heating and cooling costs.
2. Wall insulation: It can be used in wall cavities to provide thermal insulation and moisture protection.
3. Roof insulation: It can be installed under the roof to reflect radiant heat and reduce the transfer of heat into the building.
4. HVAC duct insulation: It can be used to insulate HVAC ducts, preventing heat loss or gain during the distribution of conditioned air.
