A popular EWI (External Wall Insulation) system, Fassatherm’s main function is to keep a building warm, saving energy and reducing the risk of damp through condensation. Made up of an insulation board base, reinforcing mesh coats and a finishing render, the insulation is often either mineral wool or expanded polystyrene (EPS). Different thickness of insulation can be used depending on the u-value required on the project.
The Fassatherm system can be fixed to multitude of substrates, making it versatile within most housebuild projects. Choosing the correct system is a decision made during the design process and Fassa specialists are on hand to offer expert advice on which system should be used, including insulation and finish thickness. Medium high rises may choose to apply the system onto steel frame, while a smaller project may allow the system to be fixed to masonry. Fassatherm can also be used to build a passive house. In the UK, it is common to add insulation via the cavity wall of an existing building, or through installing panels internally, however to avoid eating into living space, Fassatherm is applied to the building exterior to maximise the area.
