Why should we use Glass Mat with good alkali resistance in thermal insulation construction?

Glass Mat is mainly used in polymer-based thin ash building exterior wall insulation layers such as expanded polystyrene, rubber powder polystyrene particles, etc. It plays an anti-crack protection role for the building's insulation layer, preventing it from being damaged by the external wall mortar. fall off and destroy the insulation layer. Therefore, the quality of Glass Mat is crucial to building insulation.

A good Glass Mat has three main indicators, namely alkali resistance, tensile strength, and breaking strain. The most important one is alkali resistance. Because the Glass Mat used in the polystyrene board thin plaster exterior wall insulation system is buried in cement mortar, it is required to have excellent alkali resistance. Good chemical stability. It can resist acid, alkali, water, cement corrosion and other chemical corrosion.
There are many manufacturers and sellers of Fiber Glass on the market now, and the quality varies from good to bad. When faced with the market being flooded with fake and shoddy products, how to distinguish the alkali resistance of Fiber Glass? The surface of better quality Glass Mat is coated with a layer of polymer coating, which smells like latex and is not pungent.
Most of the fake and inferior Fiber Glass use urine glue, PVC emulsion and vinyl acetate emulsion, which have a pungent smell. A good Glass Mat has better toughness, relatively stable chemical properties, resistance to alkali, acid, water, cement erosion, and other chemical corrosion, and is relatively safe to use. The polystyrene board exterior wall insulation system can have a service life of 40-50 years.
If a Glass Mat that is not resistant to alkali is used, it will pulverize and break in the alkaline environment of the cement, which will greatly shorten the service life of the entire system, so alkali-resistant Glass Mat must be used.
