Products Description
External wall insulation (EWI) systems are an effective way to improve the energy efficiency of buildings by reducing heat loss. They typically consist of a layer of insulation material, such as polystyrene board (EPS), a reinforcing layer of alkali-resistant glass fiber mesh cloth, and a protective layer of mortar.
The fiberglass mesh is an important component of the EWI system, as it provides additional strength and durability to the insulation layer. It helps to prevent cracking and delamination of the protective layer, which can occur due to thermal stress, moisture, or impact from external forces. The mesh is embedded in the mortar layer and serves to distribute the load evenly across the surface of the insulation, enhancing its overall stability and longevity.
During installation, the External wall insulation fiberglass mesh is laid over the insulation board and held in place with special anchors or adhesive. It is then coated with a layer of mortar to create a smooth, finished surface. The mesh should be laid horizontally, with overlaps of at least 100mm to ensure a strong and continuous bond. In areas subject to greater impact, such as the bottom two meters from the ground, additional mesh reinforcement may be required.
The use of fiberglass mesh in EWI systems is widely recognized as a best practice for ensuring the long-term performance and durability of the insulation. It is particularly important in areas with extreme temperature fluctuations or high humidity, where the risk of thermal stress and moisture damage is greater. By properly installing a External wall insulation fiberglass mesh reinforcement layer, building owners can significantly reduce their energy costs while also protecting the structural integrity of their buildings.
