Brest Strong Method

This is an exterior wall construction method for wooden single-family houses using pre-mixed lightweight cement mortar that complies with deterioration prevention grade 3 and thermal insulation performance grade 4, without using ventilation battens.

To enhance the durability of wet-type exterior walls in wooden single-family homes, a ventilation structure using ventilated battens is common. However, compared to traditional direct bonding methods (non-ventilated), the thickness of the wall increases due to the thickness of the battens, necessitating changes to specifications such as windows and water drainage metal. Additionally, there are negative factors such as the cost of installing vapor-permeable waterproof sheets and battens. The Breastlong method addresses this by placing countless dots, 1.2 mm in height, on the back of the waterproof sheet instead of using battens, creating a ventilation pathway between the substrate material and maintaining a low moisture content in the substrate material, comparable to the ventilated batten method. The construction process is similar to traditional direct bonding: applying the waterproof sheet → attaching the lath → applying the mortar.
