Glass wool and its uses:
The resin bonded glass wool comes as a “blanket” which is rolled and put in a large plastic bag or as a "rigid board". 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 10,12 16, 24, 32, 40 and 48 kg/m3. There are also non-standard density products - such as 22 and 27 kg/m3.
2. Thickness: normally 25mm and 50mm
3. Length- depends on the use
4. Width: is standard of 120 cm
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”
