Information on Glass Wool Insulation


Glass wool is made up of borosilicate glass comprising of constituents such as fixing agents, recycled glass and silica sand. Therefore, glass wool is usually in the form of raw material when mixed with insulating materials. It comes in 2 categories; superfine wool and loose wool. The loose wool is the most popular choice as it is used for the production of asphalt-bonded glass blanket and glass wool board. Moreover, loose wool also helps in preservation of heat to the pipelines and exterior-protected construction.

Production of Glass Wool

During the production of glass wool, thick layer of glass fibers is cured at 200 degree inside an oven. The curation allows binding of the strands which later helps in reducing the sheet’s thickness. Afterwards, it is then melted inside an electrical furnace at 1100 degree Celsius and then transferred inside gas-fired furnace for conditioning. This is done in order for the fibers to spun. The process of glass wool production is similar to the production of candy that requires high-speed rotation. The rotation or spinning helps the binding agent to blend with the glass wool. Moreover, the process of glass wool production does not involve development of HCFCs and CFCs.

The produced fibers are then transferred to a collection chamber in the form of a mat which is then later transferred to an oven for curing. The curation is done in controlled conditions that help in achieving density and thickness.

During the time of glass wool installation, it is important to keep it dry at all times from moisture.
