WILMINGTON, Del. – DuPont Protection Solutions announces three shorter roll lengths of the DuPont™ Flashing Systems products, part of the DuPont™ Tyvek® Building Envelope business. The new size options are DuPont™ Flashing Tape in a 4-inch wide x 33-foot roll, DuPont™ FlexWrap™ NF in a 9-inch wide x 15-foot roll, and DuPont™ StraightFlash™ VF in a 6-inch width x 25-foot roll. These convenient roll lengths compliment the current longer rolls of DuPont™ Flashing Systems that are available in 75 or 125 foot options.

These new sizes are for single-use projects or smaller applications when flashing doors, windows and exterior penetrations such as HVAC, electrical and plumbing materials. “DuPont did interviews with installers, builders and contractors that showed that many times excess flashing products from a job does not always get taken to the next job, causing added construction expense,” said Alan Hubbell, Tyvek® global marketing manager. “The shorter roll lengths allow remodelers, builders and contractors to use DuPont quality flashing products without the investment of larger bulk quantities.”

The new roll lengths are designed for the most common dimensions of standard sized windows and doors. The three products with new size options are:

• DuPont™ Flashing Tape – a durable, self-adhering flashing tape and the 4” x 33’ roll is ideal for flashing either a standard flanged door up to 6’ 8” high x 5’ wide, or a flanged window up to 6’ high x 7’ wide, excluding the sill flashing.
• DuPont™ FlexWrap™ NF – the original flexible, extendable self-adhesive flashing and the new 9”x15’ roll is suitable for flashing two 6’ wide window or door sills, or flashing an arched window top and sill, as well as exterior wall penetrations such as electrical, HVAC and plumbing areas.
• DuPont™ StraightFlash™ VF – a unique double-sided flashing for a durable seal around non-flanged or brick-mold doors and windows. The 6”x 25’ rolls contains enough to flash one 6’8” tall x 5’8” wide standard door, or one tall door up to 8’ tall x 4’4’ wide, or windows up to 6’ tall x 7’ wide, excluding the sill flashings.

Like the full line of DuPont™ Flashing Systems products, these products work together with the complete line of DuPont™ Tyvek® weather resistive barriers to allow for superior building envelope protection, and are made with 100 percent butyl-based adhesive that meets or exceeds AAMA 711-13.
