Lightweight BD-30 outer wall insulated with EUROPERL PERLITE
The walls inner surfaces complies with the requirements for a Class 1 cladding and outer wall surfaces can be used in places where at least a Class 2 cladding may be required, if necessary vertical. Joints between the plasterboard must be supported by 25 x 50 mm
For load-bearing walls, the load-bearing capacity of the posts must be 45 x 170 cc – 600 mm verified for the purpose of fire impact (load combination 4 according to DS 409). Alternatively, a further layer of 13 mm plaster can be installed under the wind gypsum or the ventilation gap can be omitted. In addition, an additional layer of 13 mm plaster must be installed on the inside of the wall. Since Europerl Perlite is nonflammable
a more lenient construction may be approved at the Danish Institute of Fire Technology.
The construction with two 13 mm plasterboard with staggered joints, padding and surface treatment provides sufficient air and vapor permeability. The plasterboard can be substituted with a 15 mm fire-resistant plasterboard such as Gyproc F and a vapor barrier.
If two plasterboard is used, the inner layer must be fixed with 10 screws per m2.
Pinetree is a very durable type of wood for exterior cladding, especially if the roof has an overhang and the cladding is kept free of the ground. Galvanized nails work their way out the construction, therefore, shiny divers are chosen, which is also more environmentally friendly!
