The purpose of waterproofing applied on facade should be to prevent the penetration of rain waters and the water vapor that might occur inside. The type of the facade cladding material, existence of eaves and the type of joinery are among the other factors that affect the chosen waterproofing techniques. TrioTex Facade Underlays protect the building surface from the effects of rain waters before the completion of facade cladding; as a second layer apart from the curtain wall, it serves as a shield against penetration of water during the lifetime of the building. It allows for the water vapor to be discharged from the building. Also, it prevents heat losses that might occur due to ventilation.

İstanbul Teknik presents solutions with TrioTex Facade Underlays that are used in this field.
