Glass Wool

Glass wool, also known as fiberglass insulation, is made by melting glass and other minerals with a significant percentage of recycled content. This melt is then converted to resilient fiber form. The glass wool insulation is lightweight and can be used upto a service temperature of 230oC. It can be used in all general-purpose applications such as pre-engineered building, commercial building, drywall partition, HVAC and automobile.

Where can you use Glass Wool?

Due to its properties, glass wool is a preferred product for all major applications.

With a service temperature ranging from sub-zero to +230oC, glass wool can be used for cryogenic applications, pre-engineered buildings (PEB), commercial buildings, HVAC, mobility and transportation, infrastructure and more.

With multiple benefits to offer, glass wool is used in ceiling (underdeck, overdeck), wall, partition, façade, duct, acoustic walls, auditoriums, theatres to name a few.

How Glass
Wool Works?

Fiberglass insulation has a laminar structure with interconnected air pockets. This creates adequate resistance to the air flow path, thereby reducing heat
and sound transmission.


How is Glass Wool Made?

Glass wool, also known as fiberglass insulation or resin bonded glass wool, is made of fused borosilicate glass which is inorganic in nature. This is melted at very high temperature and fibers of long lengths are spun from it.

The uniformly distributed fibers are cured in an oven with a binder and converted to boards and rolls of required  density, and dimensions. Factory applied facings on one side or both sides of the insulation are then applied to suit the application requirements.


Sand, soda ash, limestone and recycled glass are stored in silos, weighed, mixed and poured into a furnace.


The mixture is melted at high temperature in an electric or gas furnace. 


The liquid glass is propelled by a centrifugal spinner to create the fibers. These are sprayed with a binder and shaped into a blanket.


The blanket passes through a curing oven where it is compressed to achieve its final thickness.


The blanket is cut to the required width. Off-cuts are recycled. A facing can eventually be glued to the blanket. 


The end of the line is equipped with a rolling machine for mats and a stacking machine for boards.


The glass wool can be compressed to up to a tenth of its volume. Multiple rolls of glass wool can be packed onto a single pallet.
