Why Vertibreak®?

Vertibreak® rainscreen insulation is an exterior wall insulation panel system that provides both insulation and an air/drainage rainscreen cavity in one product, eliminating the need in many cases for the use of furring strips as your rainscreen cavity. 2'x4' (610mm x 1220mm), 4'x4', or 4'x8' panels are recommended for application on above grade walls.

Vertibreak® provides a drainable, continuous insulation panel which not only contributes to the energy efficiency of the wall expected of an exterior insulation and to the durability of the wall system expected from a rainscreen cavity, but it also reduces thermal bridging through the studs, resulting in a superior thermal performance to the building envelope when compared to many traditional wall systems.

For stucco and lightweight thin veneer stone applications, Vertibreak 4-S, 6-S, and VC-S come with an exterior 'sacrificial layer' covering the front of the insulation in order to block stucco and mortar from filling the cavity.
