Foil insulation used under galvanized roof sheets helps greatly limit heat transmission, making interiors cooler in hot weather and warmer in cold situations by reflecting radiant heat away from the building. It enhances overall energy efficiency by reducing the demand for air conditioning and heating, which decreases power expenditures.
The foil layer also works as a moisture barrier, helping to decrease condensation buildup on metal roofs that can otherwise lead to rust, corrosion, and dripping inside the structure. it promotes home comfort by eliminating temperature changes and can provide some sound insulation by lowering noise from rain or other disturbances. Overall, it extends roof life, increases durability, and offers a more comfortable inside atmosphere.The functioning principle of foil insulation under galvanized roof sheets is based on radiant heat reflection and thermal resistance.
The aluminum foil surface has great reflectivity, thus it reflects a considerable part of incoming solar radiation out from the roof instead of allowing it to enter into the building. At the same time, the air gap or foam layer beneath the foil functions as an insulating barrier that slows down heat conduction and minimizes heat transfer from the hot metal roof to the interior space. In addition, the foil surface has low emissivity, meaning it does not easily absorb or re-radiate heat, which further restricts heat gain inside the building.
