FIBRANxps 700-L s a thermal insulation board made of extruded polystyrene, having a smooth surface and edges in the shape of letter “L” to prevent the formation of thermal bridges.
Application
Thermal insulation gives unconditional protection in humid environment and/or under extremely heavy mechanical load.
- Thermal protection under foundation slabs.
Instalation
All construction requirements should be taken into account during the application of FIBRANxps panels. FIBRANxps panels should be placed on flat and clean surfaces. They can easily be cutusing a sharp knife or heated wire. Most FIBRANxps product edges are L or D shaped. The panels are usually installed in a single layer. The application of double layer is desirable for I shaped panels, to avoid the consequent formation of thermal bridges at the joints. Thermal insulation in the inverted roof application should be installed in a single layer. No naked flames should be used during the installation of FIBRANxps extruded polystyrene panels. Whenever FIBRANxps panels are to be applied over waterproofing film on basement walls, adhesives tape should also be used. In the event of basements with ahigh water table, the damp proofing product should be applied to the entire wall surface. When using FIBRANxps on larger surfaces, especially on warm flat roofs, the dilation or contraction of the panels due to temperature must be taken into account. The construction of expansion joins with stonewool is recommended in such cases.
FIBRANxps panels are resistant to cold weather, rain and snow, but not to long-term exposure to ultraviolet radiation from direct exposure to sunlight. Therefore the packaging must only be removed immediately prior to application of the material. In the event that the packaging is torn, the material must be protected from direct sunlight. Although FIBRANxps panels are arnong the most durable materials on the market, contact with sharp objects can destroy or warp their surface. FIBRANxps panels can be used up to a temperature of 75 oC. However, if stored outdoors and exposed to direct sunlight, or covered with dark-coloured material, they may deform due to high temperatures. FIBRANxps panels must not come into contact with organic solvents such as acetone, petrol ortar. If the panels are to be cleaned, a test of the material’s tolerance is recommended. Please consult out technical department, if necessary. They are generally resistant to soap and detergents, but not to bleach. FIBRANxps panels are partially resistant to substances such as vegetable oils and fats, paraffin, phenol, which means that long-term exposure too such substances can affect the appearance or structure of their surface. FIBRANxps panels are particularly resistant to water-soluble asphalt materials, lime, cement, lime mortar, seawater, as well as thin dilute acids and silicones. A preliminary test is recommended in case of doubt.
