EWI (External Wall Insulation) system for providing thermal insulation and additional thermal insulation of previously EPS-insulated buildings with silicone, polysilicate and acrylic external render and wood/board eff ect, as well as renders for spray application from the AKORD line

The KABE THERM RENO EWI system is the most popular system of thermal insulation for external walls and for providing additional thermal insulation to walls with an existing EPS-based system*. It is applied in single-and multi-family housing construction industry, public utility and industrial buildings, to the height of up to 25 m (for the buildings erected before 1 April 1995 to the height of eleventh story, inclusive) and in frame buildings. Because of its simple installation technology and low implementation costs, it is most frequently used for the thermal upgrade of buildings constructed using old energy-consuming technologies (non-compliant with applicable thermal insulation requirements). The system can be applied on walls made of small-sized masonry elements (such as e.g.: bricks, blocks, stone, etc.) or of concrete (poured on site or in the form of prefabricated slabs) or in the form of OSBs (wood-based oriented strand boards) according to PN 300 standard, with a density of not less than 780 kg/m3 and bending strength not less than 16 MPa. The OSBs are fi xed with the use of KOMBI RAPID polyurethane adhesive and mechanical fi xings. The system can be used on new walls, as well as for renovation of the existing ones. It is also possible to use it on horizontal or inclined surfaces, that are not exposed to precipitation. The external system layer can be made using PERMURO and PERMURO AKORD acrylic renders, NOVALIT T and NOVALIT T AKORD polysilicate renders or ARMASIL T and ARMASIL T AKORD silicon renders, available in a wide range of colours and textures, as well as with the wood/board eff ect. After wetting the ARMASIL T silicone render, the eff ect of water molecules “being repelled” by silicone resin is observed on its surface. This eff ect protects façades against precipitation and reduces soiling deposition.

• Reduction of building heating costs
• Improved microclimate inside the building
• Wall protection against adverse weather conditions
• Protection against the growth of algae and fungi
• A wide range of types, colours and decorative eff ects of renders
• Opportunity to provide additional external wall insulation for buildings with existing EPS-based insulation
