Certificate type
Loadbearing timber stud partition system with 30–60 minutes fire resistance.
Application
Loadbearing timber stud partition system.
Description
Loadbearing timber stud partition 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 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.
- High performance building board that when installed offers the speed of dry-wall with the robustness of blockwork saving in space, time and money.
