Bucket membranes – High-density polyethylene pressed films are widely used in the installation of heavy insulation (the so-called. bucket ones), which, thanks to the embossing, do not fully adhere to the substrate. So free space created – air ventilation gap - allows moisture to escape from the substrate. Such a foil is used for vertical insulation of external walls, under the floor and on the inside on damp surfaces.
Liquid mastic, bituminous emulsions and coatings
Liquid adhesives and emulsions are used as independent waterproofing coatings or for gluing roofing paper and foil and impregnating the substrate. Mastic, made of various types of bituminous materials, can be used cold or hot. In the first case, the coating dries after the solvent evaporates, and in the second, when his temperature drops. The binders can be an independent coating for vertical insulation in dry soils on previously plastered walls. Water-soluble asphalt emulsions are used to reduce water absorption and as a base for other insulation. They can be used on moist substrates.
Putty asphalt and asphalt-rubber compounds, is a material that replaces roofing felt in rolls, recommended for irregularly shaped insulated parts of the building. Bitumen insulating coatings can be used in conjunction with fleece stuck to the bitumen coating, which acts as a reinforcing matrix.
