Light one-component mortar with very low thermal conductivity, based on cement, light fillers and special additives, recommended for thermal insulation of facades and internal walls. It is waterproof, resistant to weather conditions and does not require additional finishing and protective coatings.

Features

• very low thermal conductivity (0.162 W / m K), lower than perforated bricks (0.33 W / m K) and cellular concrete block (0.35 W / m K)
• as thermal insulation against extreme temperature changes, it prevents the cold wall effect and surface condensation on internal walls
• allows you to save energy in houses and buildings equipped with air conditioning and heating systems
• as a water vapor permeable material, it allows the substrate to breathe without creating a water vapor barrier
• good adhesion to most of the most popular materials in construction: concrete, bricks, cement mortars, blocks, parts in kno-cement fibers, etc.
• easy to mix and use, just add water and apply by hand with a trowel or spray, thanks to its high efficiency saving man-hours

Application

• thermal insulation of walls, ceiling, pillar, etc. in indoor spaces
• thermal insulation of building facades in residential buildings, hotels, offices, etc.
• base layer or first coat under thermal insulation boards (polystyrene or polyurethane) or acoustic insulation
• waterproofing layer of walls increasing their thermal insulation
