British Gypsum Gyproc ThermaLine Basic is a Gyproc WallBoard bonded with polystyrene foam to create the ultimate insulation combo.  ThermaLine Basic is a perfect thermal wall insulation solution to regulate the heat flow in any house or building. It features a closed shell structure which essentially works as an effective insulator due to a stable R-value. This characteristic reduces heat loss by almost three times  as any standard product would, eventually reducing your heating bills as well. 

Gyproc ThermaLine is lightweight and may be cut using a plasterboard saw. Available with tapered edges, Gyproc ThermaLine Basic provides a smooth and crack-free finish. This British Gypsum insulation product is famous for its high-quality moisture resistance. However, it must be noted that ThermaLine Basic is not suitable for areas that are perpetually damp and humid, or placed in areas where temperature will consistently reach above  49 degrees. Thanks to the polystyrene and ivory WallBoard combo it has excellent resistance to freezing temperatures and can withstand the cold without being damaged easily. This insulation board doesn't support the growth of any bacteria, fungi, or other microorganisms.

As mentioned before, ThermaLine Basic is a factory-bonded expanded polystyrene insulation product that is a sustainable alternative to your standard insulation boards. Gyproc WallBoard doesn't incorporate the use of harmful gases like CFCs and HCFCs. Gyproc ThermaLine Basic does not have an Ozone Depletion Potential (ODP) and has a meagre Global Warming Potential of less than 5.
