How High-Perm Exterior Tape Completes a Vapour-Permeable WRB System
A vapour-permeable WRB cannot perform as a continuous weather and air-control layer unless its laps, board joints, penetrations and transitions are properly sealed. Learn how high-perm exterior acrylic tape helps complete the system while supporting outward drying.

Self-Adhered WRB vs Mechanically Fastened Housewrap: How to Choose
Self-adhered WRB and mechanically fastened housewrap can both provide effective water-resistive protection, but they differ in installation method, substrate requirements, air-control continuity, drainage strategy and total installed cost. This guide explains where each system makes sense and what buyers should evaluate before selecting a product.

How to Choose Building Envelope Tapes: Acrylic, Butyl, Vapor-Open and Vapor-Control Options
Building envelope tapes should not be selected by adhesive chemistry alone. Acrylic, butyl, vapor-open and vapor-control tapes may serve different functions depending on the substrate, wall assembly, moisture direction, exposure condition and installation sequence. This article explains how to think about tape selection for WRB seams, membrane laps, window openings, interior air and vapor-control layers, deck joists and critical waterproofing details.
