24 Airtightness and Moisture Management Vario XtraSafe is one of the most advanced airtightness and moisture management systems currently on the market. It helps to enhance the thermal performance of the building by removing unwanted draughts whilst protecting the building structure from damage caused by moisture. Key benefits Provides a total building airtightness solution, which can go above and beyond current regulations for both airtightness and moisture control. Prevents unintended air leakage through the building fabric, keeping the warm air in and the cold air out. Smart Vapour Control Layer adapts to relative humidity to help protect the building structure from moisture accumulation and allow it to dry out. In Summer - as the structure warms in summer, the membrane s micro pores open, allowing vapour to escape from the structure. In Winter - the membrane forms a barrier, preventing water vapour from the warm interior diffusing into the structure. One man installation reduces the total installed cost and makes the system exceptionally quick and easy to fit. Easy to adjust when fitting - simply remove and refit with no wastage, damage or hassle. Vario XtraSafe can be used in a diverse range of applications: Timber Frame Buildings On roofs, walls and around windows and doors, sealing up any openings or penetrations in the building envelope where heat might be lost. Masonry Buildings On roofs, around windows and doors and also to seal up any opening or penetrations in the building (such as vents for tumble dryers) where heat can be lost. Steel Frame Buildings In steel frame structures such as commercial and retail buildings, Vario XtraSafe can be used in the same applications as on timber frame structures Isover Technical Advice Tel:
