As part of the Barricade System, Thermo-Brace exterior wall sheathing is a vital component, protecting the wall envelope and preserving the integrity of what’s inside, i.e. cavity insulation, studs, drywall, etc.
Fiberboard sheathings tend to be spongy because of their composition. This makes it difficult to fasten the edges tightly to the wall frame, creating gaps and cracks for water to enter.
Because of Thermo-Brace’s 1/8″ thickness, a tight seal is formed to the framing members, producing excellent protection against water and air infiltration.
All grades of Thermo-Brace have been evaluated and permitted as a water-resistive barrier (WRB) noted in IRC Section R703.2 and IBC Section 1404.2.
