Composite foils as insulation and vapor barrier for building insulation
Modern foils used as a composite for building insulation act as a vapor barrier and thermal insulator. Composite means several layers of different foils. Different types of foil are bonded mechanically or chemically.
Building insulation through functional composites
Builders can easily achieve one goal with composite foil: more living space thanks to thinner walls. Aluminum foil is often used in combination with other materials.
Metallized films are sandwiched between two protective films. Care should be taken during installation to ensure that the outer skin is not damaged. Any damage, however slight, will considerably reduce the insulation.
Sound insulation, thermal insulation with plastic scrims
Composite foils are used to reduce noise and heat loss from buildings. Building owners can apply for state subsidies for building insulation. Such foil laminates can be installed in a space-saving manner and offer efficient values in terms of sound insulation and heat radiation. In thermal insulation, efficiencies of 96 % are common at moderate costs.
Roof insulation and installation
Modern roof insulation materials can replace thicker mineral or rock wool. Where conventional insulation materials use 12 cm thick sheets to achieve an insulation value, composite materials can sometimes achieve comparable insulation values with much lower thicknesses.
The combination of mineral wool and metallized foil laminates can be used for the insulation of roofs, walls and floors. They are equally suitable for new buildings, extensions or any type of renovation. When it comes to dismantling, the foil composite has an advantage because it is easier to dispose of due to its smaller volume. They are extremely flexible, which is a further advantage when used for complicated building elements such as dormers.
The processing of the sheets of laminated film is usually carried out with special adhesive tape. When used in this way, the individual sheets are joined together to form a continuous bond that saves a lot of space.
Plastic scrims are increasingly developing into an insulating material in the construction industry that is replacing conventional volumetric insulating materials due to its versatile use.
