Applications Air barrier, smart vapor retarder, and dense-pack reinforcement all in one. INTELLO Plus® is the keystone to long-lasting airtightness and intelligent vapor control in walls and roofs. Advantages Vapor Variable: Low Class II vapor retarder in winter (<0.13 Perm), protects against condensation, and maximum vapor openness in summer (13.2 Perm) to facilitate rapid drying to the interior in summer. Protects the assembly during construction high humidity periods (>70% RH) with a DIN 68800-2 compliant, Hydrosafe value of 1.6 perms Works with wide range of insulation materials, including Gutex wood fiber and cellulose dense-pack, Havelock wool, stone wool, fiberglass, and many others. The semi-translucent material allows dense packed blown-in insulation to be inspected after installation PHI Certified Class A Passive House Component Living Building Challenge Compliant — Red List Free 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: Vapor-variable polyethylene copolymer protected by Polypropylene microfiber fleece Tensile strength: has mesh reinforcement for durable blown-in insulation Permeability: VAPOR VARIABLE from 0.13 to over 13 perm – best in class (factor 100) Class A material per ASTM E84 test (0 FS, 35 SDI) Air permeance per ASTM E2178 0.00005cfm/ft2 (0.0025 L/s*m2) UV/weather Resistance: if direct UV/weather exposure is expected - use INTELLO X
