When construction began on the Monarch at Waugh Chapel multifamily development in Gambrills, Maryland, protecting the building from the elements was a primary concern. A water- and air-tight wall assembly is vitally important for controlling issues such as mold growth, protecting indoor air quality and maximizing energy efficiency and occupant comfort.
Water can find its way into a wall in numerous ways. High humidity and extreme temperatures can cause vapor diffusion when warm indoor air causes condensation on colder outside surfaces. Wind-driven rain can be forced into small openings in the exterior cladding at joints, laps, and utility cutouts, and wind blowing around the building can create a negative pressure within the wall assembly which siphons water into the wall. A high-performance weather barrier is an important tool in guarding against these elements.
Drawing on previous experience with what had proven to be a high-performing option, the projectās weatherproofing contractor specified the TYPARĀ® Weather Protection System. They ultimately installed 175 rolls (175,000 sq. ft.) of TYPAR MetroWrapā¢, 1,000 flashing panels, 600 rolls of 4ā straight Butyl Flashing, 140 rolls of 9ā Flexible Flashing and 525 rolls of construction tapeāall designed to work together to create a water- and air-tight building envelope.Ā

Ben Gilstein, assistant project manager for Bozzuto Constructionāthe general contractor on the project, said this project was the first time he had worked with TYPAR and he came away impressed in the productās performance and ease of installation.
Because the development is four stories, the team needed a commercial-grade building wrap that could withstand high wind loads. TYPAR MetroWrap has a tear strength five times greater than other commercial building wraps, ensuring it would hold tight for the duration of the project. And because it is available in larger rolls, the installation crew was able to cover more square footage per pass without having to come down out of the lift bucket. In addition, TYPAR MetroWrap is rated for up to 12 months of UV light exposure without any degradation, so longer commercial project timelines wouldnāt be an issue.
āItās just a heavier-duty product that really holds up to the elements,ā Gilstein said. āIn terms of commercial construction where you have a lot of moving parts, itās certainly a pleasure to see a product that is durable, that can stand up to a construction site and is super easy to install.ā
