KRS Perlite board energy-saving insulation material

Perlite insulation board, also known as waterproof perlite insulation board, is made of expanded perlite block material as aggregate, adding waterproofing agent and binder, by preparation, screening, pressure molding, drying and other processes.

Expanded perlite is a white ultra-lightweight aggregate that ranges from very fine powders to aggregates with a particle size of up to 6 mm. It is inorganic, inert, pH neutral, biostable and asbestos-free. It provides excellent thermal insulation over an extremely wide temperature range.

It also has a highly adsorbent surface and very low packing density, which makes it an ideal carrier or low-cost filler for many compound formulations.

The advantage of perlite insulation products is that they contain rust inhibitors, which are activated if the insulation comes into contact with moisture. This inhibitor neutralizes any chloride present, thus greatly reducing, if not completely eliminating, underinsulation corrosion.


    Light weight, very low packing density.

    High water resistance and high hydrophobicity.

    Low thermal conductivity.

    High temperature insulation up to 650 °C.

    Fire, corrosion, moisture, sound insulation.

    Roof and wall construction is safe and easy.

    Environmental protection.

    Waterproof, non-flammable, loose insulation improves the thermal performance of masonry walls and floors.

    Insulation corrosion resistance (CUI).

    product usage

    High temperature insulation and thermal protection.

    Low temperature applications: non-combustible ultra-light mineral aggregates with excellent thermal insulation and adsorption properties.

    Fire and sound insulation.

    Swimming pool, cold storage, boiler and some insulation works with special waterproof requirements.

    Perlite insulation is used in high temperature applications in the steel and casting industries, such as ladle toppings, hot toppings and risers.

    Expanded perlite is suitable for a range of landscaping applications, such as green roof construction, golf green renovation and construction, flower POTS, drainage systems.

    Expanded perlite powder and board is a hydrophobic insulating aggregate.
