What is Perlite Board?
Perlite board is a lightweight insulation material made from expanded perlite, a volcanic glass that, when heated, expands to form a porous structure. This unique property makes perlite an excellent insulator, as it provides thermal resistance while being easy to handle and install. Its fire-resistant characteristics and eco-friendly nature contribute to its increasing popularity in the roofing industry.
Benefits of Using Perlite Board in Roofing
1. Thermal Insulation
Perlite boards provide significant thermal insulation, keeping buildings cool in summer and warm in winter. This leads to reduced energy consumption and lower utility bills, making perlite an environmentally friendly choice.
2. Fire Resistance
One of the standout features of perlite board is its Class A fire resistance. This makes it an ideal choice for roofing applications where fire safety is paramount, giving homeowners and builders peace of mind.
3. Lightweight and Easy to Handle
The lightweight nature of perlite boards simplifies the installation process. This not only reduces labor costs but also minimizes the structural load on buildings, making it suitable for various applications.
