Industry Knowledge of Perlite Insulation Bricks

Perlite insulation bricks, also known as expanded perlite insulation bricks, are an incredibly popular type of building material that is widely used in the construction industry. This type of insulation brick is made from perlite, which is a volcanic rock that expands when heated to high temperatures.

One of the key technical parameters of perlite insulation bricks is their thermal conductivity. This parameter indicates the rate at which heat is transferred through the material, and is measured in W/mK (watts per meter kelvin). Perlite insulation bricks typically have a thermal conductivity of around 0.10 to 0.15 W/mK, which is quite low compared to other types of insulation materials.

Another important technical parameter of perlite insulation bricks is their compressive strength. This parameter indicates how much weight the bricks can bear before they start to deform or break. Perlite insulation bricks typically have a compressive strength of around 2.0 to 2.5 MPa (megapascals), which is more than sufficient for most building applications.

The production process for perlite insulation bricks is fairly straightforward. First, raw perlite ore is crushed and screened to remove impurities. The purified perlite is then mixed with a binding agent, typically cement or a lime-based material, to form a slurry. This slurry is poured into molds and allowed to dry and harden.

Once the perlite insulation bricks have been formed, they can be used in a variety of construction applications. They are commonly used as insulation for walls, roofs, and floors, and can also be used as fire protection material. Perlite insulation bricks are lightweight, easy to handle, and have good sound absorption properties as well.

Overall, perlite insulation bricks are a versatile and effective building material that offers a range of technical benefits. Their low thermal conductivity and high compressive strength make them an ideal choice for insulation in a wide range of construction applications. Additionally, their ease of production and handling make them a cost-effective and efficient choice for builders and contractors.
