Gyproc ThermaLine PLUS

Gypsum plasterboard bonded to an extruded polystyrene foam insulant providing a vapour control layer for an intermediate level of thermal insulation.

9.5mm1 Gyproc WallBoard factory-bonded to an extruded polystyrene insulant that is both CFC and HCFC-free, meaning zero ODP (Ozone Depletion Potential), and less than 5 GWP (Global Warming Potential). The closed cell structure of the foam provides integral vapour control. Designed to be used in both refurbishment and new build for walls, ceilings and reveals where a medium level of thermal insulation is required to reduce heat loss from buildings.

What is the thermal conductivity of Gyproc ThermaLine laminates?

Our Gyproc ThermaLine laminates comprise of plasterboard (thermal conductivity 0.19 W/mK) and rigid foam insulation (thermal conductivity of the foam ranges from 0.02 to 0.04 W/mK depending on type).

How do you upgrade existing walls thermally?

This can be achieved either externally (EWI) using an insulated render system such as Weber, alternatively this can be achieved internally (IWI) using a frame system (such as our GypLyner UNIVERSAL) comprising of insulation within the cavity or through the use of an insulation backed plasterboard (installed in one of our DriLyner systems). Please refer to WHITE BOOK Chapter 07 Section 01 Page 02 for an overview of our British Gypsum wall linings range.
