PIN BOARD / SOFT BOARD
Bagasse is reduced to fibres which are then felted to form a continuous sheet. After cutting to approximate size, the sheets are passed through a drying oven. These sheets are trimmed to board sizes.
Improved acoustic properties are obtained by grooving insulating boards to part of their depth in various patterns.
Sizes generally available are:
Sheets: 1220mm x 2440mm (4′ x 8′) and 1220mm x 1220mm (4′ x 4′) Thickness available are 8mm, 10mm, 16mm, 22mm.
