Glass wool

Glass wool

Glass wool Insulation is one of the most widely used forms of insulatino world-wide because of its thermal and acoustic insulation properties, light weight, hogh tensile strength and exceptional resilience. Glass wool is the most dominant type of insulation used in applications with service temperatures between -50 oC to +250 oC, with a world-wide market size of approx. US $7 billion.

Glass wool consist of fine, long, inorganic fibers bonded together by high temperature binder. Ther fibers (each of approx. 6 – 7 microns diameter) are distributed in such a way as to trap millions of tiny pockets of air in the product, thereby creating its excellent thermal and acoustic insulation properties. the product is light gold in colour and its superior tensile strength and resilience makes the product ideal for applications in which there will be vibration, jolting or high compression. The light weight and handleability of Glass wool also offers significant advantages during transport and installation. In addition, Glass wool is chemically inert and has no impurities such as iron shots, sulphur and chloride. The product is non corrosive to metal and does not support mold grow.

Resin Bonded Fibre Glass wool

The use of Glass wool for the thermal insulation of external walls and ceiling has been shown to reduce energy consumption by 20% to 30%. Glass wool is manufactured from widely available and renewable raw materials and provides environmental benefits in terms of resource saving and energy saving in every stage from pre-manufacturing to end use.

  • Thickness: 25 to 100 mm | Width: 1220 mm | Length: 1 to 1.2 mtr
  • Available Densities: 24 to 120 kg /m3

Glass wool Slabs

Glass wool is an insulating material made from fibres of glass arranged using a binder into a texture similar to wool. Glass wool is available as a “rigid slab” which can be used in various underdeck insulation applications, wall panelling, filling dry wall partition cavities.

  • Thickness: 25 to 100 mm | Width: 1220 mm | Length: 1 to 1.2 mtr
  • Available Densities: 24 to 120 kg /m3

Fiber Glass & Black Glass Tissue

Fiber Glass tissue is a non woven felt made of randomly oriented glass fiber distributed In a special binder by a wet-lay process. Available in a variety of densities, it serves as a wrap for both underground and overground pipeline systems to counter natural and artificial corrosion.

Black Glass Tissue is a black non-Woven felt made of randomly oriented glass fibers distributed in a special binder By a wet-lay process. It minimizes fibre fall – out from insulation materials in various applications. Improves finish quality and look and ease handling of insulation material.
