New RainDroplM- the advanced moisture-management housewrap that not only functions as an air and moisture barrier but also has unique drainage channels built into the surface of the housewrap. When water penetrates the siding, RainDrop's unique drainage channels provide space for the moisture to drain to the base of the walls.. .and allow air movement between the exterior siding and the face of the housewrap.

Contact Pactiv Building Products jOr special installation details, such as housewrap and flashing integration, penetrations. and sealing techniques. 07270 - 3 e '=' PACTIV Buikli1gProdlKts ; < . I. Install housewrap over structural sheathing board or insulation board. 2. Begin by aligning the bottom edge of the roll with the base of the wall, approximately 2 feet (610 mm) from a corner, with the print side facing out and the black strands ronnin!! verticallv down the wall. Fold several inches (mm) of material under itself and fasten securely to a structural sheathing or through insulation board to an underlying framing member. 3. Unroll the housewrap with the printed side out, wrapping the entire building, including door and window openings. Common roofing nails, plastic cap nails, or staples with a minimum I inch (25 mm) crown may be used for attachment of the housewrap to structural sheathing or through insulation to framing members. If smaller crown staples are used, then more fasteners must be used. When installing housewrap over non- structural sheathing such as insulation board, fas1eners should penetrate the underlying stud a minimum of 1/2 inch (13 mm). Fasteners should be spaced every 12 inches (305 mm) along every other stud location and every 6 inches (152 mrn) around door and window openings. 4. For best results, a modified "I" pattern should be made through the housewrap at window openings. Fold excess material inside the rough opening and fasten securely through all layers to a framing member. If doors and windows are already in place when installing the housewrap, trim as close to them as possible and tape housewrap edges. Use Pactiv Contractor Tape (Enhanced Adhesion) or equivalent tape to seal housewrap seams and around openings, window flanges, door jambs, sill plates, pipes, ducts, etc. Use of window flashing materials is encouraged. Refer to the Pactiv Building Products Housewrap Installation Guide for detailed information. 5. When the end ofa roll is reached, fold the edge of the housewrap under itself and attach to the structural sheathing or through insulation board to an underlying framing member. Vertical and horizontal seams must be overlapped a minimum of6 inches (152 mm) unless other wise specified for a particular application. Upper courses of housewrap must overlap lower courses (in water shedding fashion). All vertical and horizontal seams must be taped using Pactiv Contractor Tape (Enhanced Adhesion) or equivalent tape. 3.4 PROTECTION A. Protect installed housewrap from damage until covered by exterior wall material. END OF SECTION 07270 - 5 as.RD 3103 ~ e PACTIV '=" lkaldingProducts
