The aluminum foil layers act as a barrier, reflecting radiant heat back to its source. This helps reduce heat gain in summer and heat loss in winter. The thermal insulation material provides additional thermal resistance, further enhancing its effectiveness.
Reflective insulation double sided foil often have a protective coating to increase their lifespan, and relatively easy to install. By reducing heat transfer through radiation, reflective insulation can help reduce the work load on air conditioning systems in summer, and minimize heat loss in winter, leading to lower energy bills. Thse aluminum foil insulations have a fire-resistant coating, making them suitable for use in fire-prone areas or in the construction of fire-rated walls and ceilings.
double-sided foil insulation is an effective tool for managing heat flow in building structures, making it a valuable component in constructing energy-efficient homes and commercial buildings. This type of insulation is ideally used as sarking and insulation under roofs, in walls behind cladding or under timber floors, for residential and commercial building. Combining with glass-wool /rockwool/ mineral wool/ foam insulation, it is excellent as a vapor barrier and reflective foil insulation for air-conditioning ducts, pipes and vessels.
