Product watch

By

Pecora’s XL-Perm Air, Vapor and Water Barrier System consists of products that work together to provide complete protection for a building envelope.

The four-step solution promotes continuity of weatherproofing barrier systems.

Step 1: Pecora XL-Flash STPU Fast Curing Liquid Flashing and Joint Filler
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 elastomeric weatherproofing membrane provides two- to three-times the coverage of other fluid applied products. XL- Perm ULTRA VP has elasticity and crack-bridging capabilities contributing to a seamless, durable and airtight building envelope. It also can 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, offering superior green strength.

Step 4: Pecora XL-Span 100% Silicone Extruded Transition Membrane
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 percent compatibility, wet or dry. Complete system testing was done using an assortment of air, vapor and water barrier materials to ensure quality. Now available, Pecora XL-Perm is a professional system that must be used in conformity with manufacturer's instructions.
