Applications INTELLO X® is a robust exterior grade vapor variable air barrier. It offers the highest level of protection for insulated assemblies against moisture induced damages in enclosures - even for challenging constructions such as vapor closed flat roofs or highly insulated walls. It can act as a temporary roof or WRB, ideal for roof renovations from the exterior. INTELLO X is the choice for many commercial builders as well as prefab panel manufacturers. It can be applied on the interior or, when temporarily exposed, applied on the exterior of buildings. Advantages Can be a temporary WRB or roof underlayment Permeability: VAPOR VARIABLE from 0.13 to over 13 perm - best in class (factor 100) Protective fleeces on both sides of smart retarder protect it from damages and UV exposure, and allow for durable tape bonds on both faces of the membrane Suitable for all types of insulation ( fiberglass, mineral wool, cotton, sheepswool, woodfiber etc) Pro Clima Intelligent Airtight system (TESCON VANA tape, ROFLEX gaskets etc) allows for fast, reliable installation Certified to ICC-AC528-Humidity dependent Vapor Retarders  - ICC ESR 4854 Properties Material:  polyethelyene copolymer protected by robust PP covers Waterproof, resists water column of 8’2″ (2.5m) UV/weather Resistance: 2 months of exposure With recommended installation details can be used as dense pack insulation netting Class A material per ASTM E84 test (0 FS, 105 SDI) Hydrosave value of 1.6 perms, protects enclosure from construction humidity
