Aluminum roofing foil can be special thermal insulation material in roofing system while laminated with other material. Such as aluminum foil rubber plastic thermal insulation material. This type of thermal insulation material is more suitable for use in cement roofs, greenhouse roofs and sun room roofs for thermal insulation, and the effect is good.
Aluminum roofing foil can be used for thermal isolation in high temperature environments. Mainly to block high temperature heat radiation. Taking advantage of the high reflectivity of the aluminum surface, the multi-layer aluminum surface reflection can achieve the purpose of completely blocking thermal radiation. However, there will still be a small amount of convection heat transfer through the air between the aluminum foil surfaces. If complete thermal insulation is required, a multi-layer vacuum aluminum reflective thermal insulation structure can be used. So we suggest that you use aluminum foil honeycomb panels as the roof, which is moisture-proof and heat-insulating, environmentally friendly and economical and has strong compression resistance.
The thermal insulation principle of aluminum roofing foil film is to reflect light, so it has a certain thermal insulation effect. If you want a good effect, it is recommended to use professional thermal insulation materials (such as phenolic board, rock wool, EPS and XPS, etc.) to choose suitable materials according to different needs. Decorative aluminum foil for roofing is one of the aluminum foils application, it has the advantages of heat insulation, moisture resistance, sound insulation, fire prevention and easy cleaning, and has a luxurious appearance, convenient processing, and fast construction and installation. The aluminum foil reflects the sunlight, thereby diverting the radiation to other places, rather than insulating it, it just acts as a thermal insulation. The brighter the roof foil, the more reflective it is. So when using it, wrap some insulation cotton inside and then wrap it in aluminum foil. The aluminum foil is actually the conduction of the outside temperature to protect the inside temperature from being affected by the outside world.
