Because the foil is highly vapor-retarding, you protect other insulation materials that need to remain dry from moisture. By trapping some air on one or both sides of the foil, you further increase the insulation value. The foil blocks up to 95% of heat radiation. Vapor-retarding: Good vapor-retarding properties are crucial to prevent water vapor from penetrating a structure and causing unwanted condensation on the cold side when it cools down. A layer of vapor-retarding insulation foil has a moisture resistance (µd) of no less than 180 meters. This makes this foil a good alternative to the foils normally used as standard in construction. Insulating effect: The insulating effect is created because the foil prevents almost all heat flow through radiation. It can be used to reduce heat radiance from warm objects or even to reflect heat. The foil is ideal for use in false walls, where it is combined with an air cavity. In some cases, it can improve the insulation value of the material by up to 40%, especially with thinner insulation. There are also numerous applications for this foil, including radiator foil, bathroom insulation, and sun protection. Fastening: The foil has a very high tensile strength, but can tear. When fastening mechanically (staples, plugs, etc.), it is therefore recommended to reinforce the foil at the mounting point, for example, with a special foil strengthener. Furthermore, the foil is incredibly thin and light. For this reason, the foil can also be secured by clamping it in place, for example, with magnets. Other fastening options include glue or tape. The advantage of these methods is that they ensure an airtight seal.
