Effect of Adding Thermal Insulation on Frost Damage of Masonry Walls
Numerous studies have been conducted on the retrofitting of brick masonry walls with thermal insulation. However, these studies did not explore the concurrent aspects of increasing internal insulation, wind-driven rain levels, brick durability, and varying brick properties. This work therefore investigates the impact of adding thermal insulation on frost damage by using the hygrothermal simulation program WUFI 6.5 Pro. The properties of five different types of bricks were used in the hygrothermal simulations, and the proposed walls were subjected to two levels of wind-driven rain exposure. The results showed that the effect of adding thermal insulation on frost damage risk is influenced by several factors, the most significant of which are the bricks’ properties and the moisture exposure level. Adding interior insulation lowers the temperature in brick, increases moisture content significantly in that interior layer, and increases freeze–thaw cycles and frost damage cycles mainly in the second and middle layers.
