During installation of British Gypsum products dust may be generated.  Any dust (regardless of chemical composition) is considered to be a substance hazardous to health under COSHH if it is present at a concentration in air equal or greater than 10mg/m3 (for inhalable dust) or 4mg/m3 (for respirable dust).

For all Gyproc plasterboards, the coloured paper face should face outwards and is the side suitable for plastering or direct decoration.

BS EN 1363-1 better replicates the way a dry lining system is installed on site. In a BS 476-20 fire test, partitions are generally constructed to no more than 3m in height. The standard allows for maximum partition heights above 3m to be based on a ‘cold-state’, without the need to test at the heights they could be installed at on site.

For partitions where no fire rating is required, or where specified to BS 476: Part 22, the maximum system height is limited to the cold state height (L/240@200Pa.) Refer to the following Technical Guidance Note.

Where moisture resistance is required in a British Gypsum partition, lining or ceiling, the moisture-resistant version of a board, in the same thickness as the original specification, can be used without impacting the system performance.

If services are required to penetrate a British Gypsum system, the system performances must be maintained. This includes fire resistance, acoustic separation and structural integrity.

British Gypsum have never used asbestos in our board or plaster products.

The natural Gypsum that makes up our Thistle plaster range varies slightly in composition from site to site due to natural impurities in the surrounding rock, one of these impurities is quartz, a form of crystalline silica.

Thistle GypPrime should be diluted before use. You can dilute it up to (1:5) 1 part Thistle GypPrime to 5 parts fresh water. One tub covers up to 440 sqm when diluted at 1:5
