FAQs

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

150mm using a single layer of 12.5mm Gyproc WallBoard.

Gyproc WallBoard Duplex and Gyproc FireLine Duplex have a water vapour resistance factor (μ) 1400 EN 14190: 2014. Condensation is common where cold meets warm in areas like roof spaces and external walls. The board's vapour control backing stops condensation entering in these areas, preventing it from affecting the structure of the building.

We recommend to stagger standard sized boards by 600mm vertically and horizontally.

We have specific guidance for using our products in both ceilings and wall lining constructions in these special wet environments where attention to detail around the specification is critical.

Gyproc plasterboard does not have stand alone sound insulation performance. However, data can be found in the White Book Specification Selector for its performance as part of a system.

We offer a range of cavity barrier systems based on Gyproc Plasterboards or Glasroc F MultiBoard mounted on Gypframe metal or timber framework.

Generally for domestic applications use Moisture Resistant (MR) grade Gyproc plasterboards and for heavier use applications our Glasroc H TileBacker

Our Gyproc ThermaLine laminates comprise of Gyproc WallBoard (thermal conductivity 0.19 W/mK) and rigid foam insulation (thermal conductivity ranges from 0.02 to 0.04 W/mK depending on type). Therefore we do not quote a composite thermal conductivity value but do quote a composite thermal resistance value (m2 K/W).
