External Wall Applications
EWI-System is a high performance external wall insulation system protected by meshcloth reinforced polymer renders, when applied to a masonry substrate have BBA approval covering various types of insulation and many render finishes.
The mechanical suspension method allows easy adjustment in depth for the distance between the supporting wall and the fixing point. This regulation is achieved through a rivet that is stuck in the mechanical suspension, which will rotate the bolt and bring closer or move away the stone.
Hardwearing and weatherproof, it is achieved by repeated spraying using a spatter machine, building-up to a minimum coat thickness of 4mm applied onto a smooth, coloured, polymer-rendered layer.It can be used on most substrates of commercial and residential buildings, including brickwork, blocks, concrete and most masonry backgrounds.
Silicone technology imparts a high degree of water repellency to the render surface whilst allowing water vapour to pass through the render allowing the substrate to breathe. The water repellent surface ensures a freshly rendered appearance for longer. The finish is dryer, which makes it more resistant to algae growth.
