NOTE: In order to make a claim under the upont Weatherization Products 10-Year Limited Product and Labor Warranty, you must have met all of the terms and conditions of the warranty, including use of the applicable upont Installation Guidelines. In the event that a specific detail or installation technique is not covered in the upont Installation Guidelines at the time you are building, then the Key Installation Requirements outlined in this document must have been followed in order to make a claim under the warranty. It is in the sole discretion of upont to determine if full compliance with the Key Installation Requirements exists. Please contact upont or a upont Tyvek Specialist if you have any questions regarding any upont Installation Guideline. General Instructions These installation guidelines are intended for buildings less than 5 Stories and low-rise multi-family residential buildings less than 6 stories when performance requirements do not exceed STM E1677 (65 mph equivalent structural load and 15 mph equivalent wind-driven rain water infiltration), and window/door design ratings that do not exceed P45. upont self-adhered flashing systems products should be installed on clean, dry surfaces that are free of frost.

Remove all wrinkles and bubbles that may allow for water intrusion by smoothing surface and repositioning as necessary. When flashing the sill area for windows and doors, upont recommends the use of 6 wide upont FlexWrap NF for 2 x 4 framing and 9 wide upont FlexWrap NF for 2 x 6 framing. s an option, if a rigid back dam is desired, cut the corner back dam the length of the sill and nail into place on the interior edge of the sill prior to installation of upont FlexWrap NF. Then install upont FlexWrap NF over sill and corner guard back dam. If using 6 upont FlexWrap NF with optional rigid back dam, seal ends of corner guard with upont Residential Sealant or recommended sealant. oor and window rough sill framing must be level or slightly sloped to the exterior to ensure proper drainage to the exterior. This best practice ensures continuous support with positive slope to the exterior. upont self-adhered flashing systems products are not intended for throughwall flashing applications. In lieu of temporarily taping, upont Tyvek flaps at window head and jambs can be tucked under the upont Tyvek air and water barrier. upont Residential Sealant should be tooled flat to allow the natural curing process to create a concave joint.

Key Installation Requirements for rainable Window / oor Installation Under the Limited Product and Labor Warranty When flashing windows or doors, the following principles must be followed: When installed properly, upont StraightFlash, upont FlexWrap NF, and upont Flashing Tape provide nail sealability at window/door openings to help protect critical window-wall interfaces. Metal sill pan flashing may be used, but must not replace flexible sill flashing that provides nail sealability. upont self-adhered flashing systems products comply with M 711-13, Voluntary Specification for Self dhering Flashing Used for Installation of Exterior Wall Fenestration Products, which has a modified version of STM 1970 that is more representative for vertical wall applications. irect water onto an acceptable air and water barrier drainage plane with an unobstructed path to the exterior of the wall. Provide a drainage path for any water intrusion through the window/door attachment system that collects at the sill. Properly integrate flashing with acceptable upont Tyvek WR in accordance with the details in this installation guideline. upont self-adhered flashing systems products must be applied with a minimum 2 lap onto the WR. upont requires that upont FlexWrap NF and StraightFlash be covered within nine months (270 days) of installation. upont requires that upont Flashing Tape be covered within four months (120 days) of installation. Ensure that window / door and flashing system design takes into account common factors that will impact performance, such as: limate considerations: Rainfall, Wind, Temperature (hot / cold cycles), Humidity uilding design: Window / Wall esign (overhangs, recessed openings, bumpouts), Wall ssembly (wood frame or masonry), Window System (wood or vinyl), New onstruction or Replacement Window drainage path UV exposure prior to the construction of the exterior facade Field testing the window / door and wall installation as a complete system is a recommended best practice.
