Thermal Bridging

Moisture can cause major damage to a building’s structure and is often times due to thermal bridging. As moisture builds up between the interior and exterior of a building, it can cause the its wooden frame to rot and deteriorate, which may ultimately lead the frame to collapse. To help correct the problem of thermal bridging, MagBoard’s™ MgOut™ positions insulation outside of the wooden frame, protecting it from potential moisture damage.

Because MgOut™ places a building’s insulation outside of the frame, condensation will be moved outside of the wall cavity, reducing the probability that moisture and mold damage will occur. In other words, the insulation eliminates thermal bridging and allows the insulation to work at its optimal point. Because of this major benefit, exterior insulation is becoming more prevalent in the building industry and building codes and standards are beginning to require it for construction.

Flameproof Companies is a top national provider of MagBoard™ products and will work with you to make sure you have the products you need for responsible construction.
