by Brianna Crandall — May 19, 2014—Facilities managers who are involved in a construction or renovation project may be interested to hear that weatherproofing product manufacturer Pecora has just introduced the XL-Perm Air, Vapor, and Water Barrier System consisting of fully engineered and compatible products that work in tandem to provide complete protection for a facility’s building envelope.
The easy, four-step solution assures continuity of weatherproofing barrier systems, says the company.
Step 1: Pecora XL-Flash STPU Fast Curing Liquid Flashing and Joint Filler
This product is a one-part, fast-curing, non-sag elastomeric STPU gun grade, trowelable liquid flashing and joint sealant specially formulated for the air and vapor barrier industry.
Step 2: Pecora XL-Perm ULTRA VP Fluid Applied STPU
Applied in a single coat via airless sprayer or roller, this durable elastomeric weatherproofing membrane reportedly provides two to three times the coverage of other fluid applied products. XL- Perm ULTRA VP has excellent elasticity and crack bridging capabilities contributing to a seamless, durable, and airtight building envelope, says Pecora. It can also be used on damp substrates and green concrete.
Step 3: Pecora AVB Silicone Sealant/Adhesive
Designed as an integral component for transition seals between dissimilar materials in air and vapor barrier systems, this sealant/adhesive reportedly offers superior green strength.
Step 4: Pecora XL-Span 100% Silicone Extruded Transition Membrane
This product is designed to offer an airtight and watertight barrier at transitions between building façade components.
All the products in the Pecora XL Perm system, when used together according to manufacturer’s guidelines, achieve 100% compatibility, wet or dry, says the company.
Complete system testing was done using an assortment of air, vapor and water barrier materials to ensure quality. According to Alan Johnson from Streamline Waterproofing and Caulking, contractors will be pleased with the results. “We’ve used Pecora on a number of projects over the years and are confident in the quality of their products. When we were able to use the new XL-Perm for the first time, I was impressed with how easy the system was to work with to provide a complete weather barrier. We will definitely recommend using it on future projects.”
Now available, Pecora XL-Perm is a professional system that must be used in conformity with the manufacturer’s instructions, reminds the company.
Founded in 1862, Pecora is an American manufacturer of architectural weatherproofing products offering a full line of silicone, urethane and latex sealants specifically formulated to provide superior quality, and a wide range of sealant properties for the commercial construction market.
