Glass Wool

Glass wool and its uses

Glass wool is used as an insulation material in buildings, air conditioning, and industrial applications. . It simply keeps warm equipment warm and cold equipment cold.

The product comes either as "loose" or as a value added - Resin Bonded Glasswool.

Resin Bonded Glasswool is more pospula in markets outside India and is sold as a “blanket” which is rolled and put in a large plastic bag. Each roll (glasswool blanket) would have a defined density, thickness, length and width.
The key dimensions for a (glass wool blanket or roll) are:

1. Density- normally 16, 24, 32 and 40 kg/m3. There are also non-standard density products - such as 12 and 14 kg/m3.

2. Thickness: normally 25mm and 50mm

3. Length- depends on the manufacturer and is not a key factor

4. Width: is normally standard of 120 cm5. You can then derive the weight of the roll (from density, and other 3 dimensions)

Another factor to consider is whether the “roll” has a aluminum sheet on one side of the roll. If it has an aluminum roll on 1 side, it is called “faced” or “FSK”
