KEWI (Kilsaran External Wall Insulation) can be applied to LGS walls, for both infill and modular loadbearing structures. The system is a mechanically fixed, external insulated render system, with a non-ventilated drained cavity. It is designed for use with NSAI certified LGS systems that are certified for infill and structural LGS up to 30m in height. The track record proven renders used on the KEWI system are supplied by Henkel Polska. The new innovative system can be used for cost-effective offsite modular construction which has many benefits including reduced labour cost, less weather delays, better Health & Safety control, rapid construction techniques and better quality. Infill panel construction in conjunction with reinforced concrete frames is a rapid build method that can be used in several situations with variable finishes including render, brick, stone and other cladding solutions.
