The production of glass wool involves mixture of borosilicate glass containing recycled glass, fixing agents and silica sand. In the beginning, the appearance of glass wool is similar to raw materials along with a mixture of insulation materials. This type of insulation is known to come in 2 types loose and superfine wool. Among these, the most popular choice is the loose wool used in the production of glass wool board and bonded glass blanket. Loose wool also has a characteristic of heat preservation entering into the pipelines.
How is it Produced? – Let’s check the steps that goes behind the production of glass wool insulation.
- At 200 degrees Celsius, thick layer of glass is curated inside an oven in order to bind the strands. The strands allow to become into thin sheets.
- Inside an electrical furnace, melting of the strands take place at 100 degree Celsius. During this step, the strands spin fast and quick with high-speed similar to the process of making cotton candy.
- Due to the high-speed rotation, formation of CFCs and HCFCs take place since the fiber starts to blend with the glass wool.
- In the end, the formed fibers would be transferred into an oven again for the purpose of curing. This last step is done to achieve density and thickness with accurate levels.
Before this production work starts, the employee or worker needs to remain dry without letting any moisture to come in contact. Glass wool insulation may be used for roof insulation in Canberra however, you will need to consult with a professional insulation contractor.
