Ideal for use under metal including copper, zinc and COR-TEN® (consult technical department for installation instructions), WIP 300HT can also be used under synthetic, concrete and clay tiles and asphalt shingles. This strong, skid-resistant membrane is available in either black or white and provides superior protection from water penetration caused by wind-driven rain and ice dams. Features and Beneﬁ ts • Protects the roof structure from water seepage caused by ice dams and wind-driven rains • Resists temperatures up to 250°F without degradation of the adhesive • Seals around rooﬁ ng nails, staples and screws • Split-release ﬁ lm provides easier, faster installation • Resists cracking, drying and rotting, providing long-term waterprooﬁ ng performance and low lifecycle cost • Concealed waterprooﬁ ng system will not detract from the architectural aesthetics of the primary rooﬁ ng system • Exposed rubberized asphalt bead along the membrane edge ensures watertightness of lap seams • 180 days exposure time Standards • UL Classiﬁ ed • ICC-ES ESR #2206 • 2009, 2012, and 2015 International Building Code™ • Florida Building Code Approved Product #6785 • Meets ASTM D1970 • Miami-Dade County Product Control Approved • ASTM E108/UL 790 Class A Fire Resistance • 2016 California Green Building Standards, Title 24 • 2015, 2012, and 2008 ICC 700 National Green Building Standard Storage WIP 300HT rooﬁ ng underlayment rolls should be stored on their side, under cover and in areas where the temperature is between 40° and 100°F (4.4° and 38°C). Do not double-stack pallets. Warranty Carlisle WIP products are backed by Carlisle’s industry-leading warranty. Carlisle WIP Products will display optimal performance when stored under recommended conditions and used within one year of date of manufacture. Product installed after one year of date of manufacture is not covered under defect warranty. Visit our website for warranty details. Installation WIP 300HT underlayment is applied when the roof deck is dry and the substrate temperature is 40°F (4.4°C) or higher. At temperatures below 40°F, nailing or priming should be used to temporarily hold the membrane in place while adhesion develops. WIP 300HT is designed to be covered with the primary rooﬁ ng system and should not be exposed to sunlight for more than 60 days (black ﬁ lm only). White underlayment offers exposure time of 180 days. Substrate must be free of any moisture. If moisture is present, it may inhibit adhesion. Prepare the roof deck by removing all loose objects, dirt, dust and debris. For re-rooﬁ ng applications, remove all old materials from the roof deck in the area to be covered with WIP 300HT underlayment. Replace water-damaged sheathing and sweep roof deck thoroughly. 05/19/2020 Priming Priming is not required on clean, dry wood, metal or most polyisocyanurate surfaces (polyiso paper facer does require priming). Masonry and exterior gypsum boards (such as DensDeck®) should be primed using an appropriate primer or adhesive. Some rigid insulation boards with porous or dusty surfaces may require priming to promote initial adhesion. Priming is required on all substrates when air or substrate temperatures are below 40°F (4.4°C). Adhesives such as CCW-702, CCW-702WB, CAV-GRIP™ and CCW-AWP are approved for use with WIP products. Refer to your local building codes to determine acceptable product for use in your region. Selection of roof deck or insulation substrate and/or use of a primer or adhesive are the responsibility of the architect, speciﬁ er or rooﬁ ng contractor to determine based on the roof assembly and environmental conditions. Valleys, Hips & Ridges Cut WIP 300HT rooﬁ ng underlayment into manageable lengths. Align over the center of the valley, hip or ridge. Remove release ﬁ lm. Press the middle of the membrane ﬁ rst before working toward the edges. For open valleys, cover WIP 300HT rooﬁ ng underlayment with metal valley liners. Eaves & Rakes Cut WIP 300HT underlayment into 10–15' pieces. Remove 2–3' of release ﬁ lm and align the edge of the membrane, sticky side down, so it overhangs the drip edge by 3⁄8" (10 mm). Continue to remove release ﬁ lm and press as you move across the roof. Use a hand roller and/or hand pressure to press into place. Overlap end laps a minimum of 6". WIP rooﬁ ng underlayment should reach a point 2' inside the interior wall line. Local codes may require additional courses. If additional courses are required, the top lap must be at least 3½". Drip Edges At the rake edge, apply WIP 300HT underlayment ﬁ rst and place drip edge on top. At the eave, apply drip edge ﬁ rst and place WIP underlayment on top of the drip edge so that it overhangs drip edge by 3⁄8" (10 mm). For standard installation details, follow the WIP detail drawings. For non-standard installation instructions, contact your local Carlisle WIP representative. Metal Roof Underlayment Under water-shedding metal roof systems or low-slope metal roofs with a minimum ½" slope, start at the low point and apply WIP 300HT over the full surface of the roof deck. Review the metal rooﬁ ng manufacturer’s instructions for limitations and precautions. Beginning at the eaves, apply underlayment from the low point to the high point of the roof, running the roll horizontally. Lap Edges Lap edge seams should be hand rolled to ensure maximum adhesion.
