Application
Independent dry linings.
Description
Metal stud lining system based on fermacell® gypsum-fibreboard linings. Homogeneous dry lining board made from recycled gypsum, recycled cellulose fibres from post consumer waste paper and recycled water.
Features and benefits:
- The board is light grey in colour.
- Available as square edged.
- Marked on the rear face with the product name and identification.
- fermacell® fibre gypsum boards offer a wealth of advantages compared to conventional interior dry lining such as plasterboard.
