GTEC Moisture Board is a plasterboard with moisture-resistant additives in the core and liner to provide protection in humid areas such as kitchens, bathrooms, and utility rooms.
Plasterboard
Plasterboard, often referred to as drywall, is made up of two layers that are wedged together with gypsum. Plasterboard is a popular choice due to how lightweight and affordable it is.
Modern plasterboards are suitable for use in a wide variety of projects, including:
- To control moisture: Ideal for use in areas that are likely to experience moisture such as steam on a regular basis. For example, bathrooms, kitchens, etc. This is because we can specifically offer moisture-resistant plasterboard, which essentially will not absorb any moisture at all.
- Thermal heating in buildings: Often used in buildings with solid walls that have not been built with the same amount of insulation as cavity walls.
- Restricting sound: We offer soundproof plasterboard, as they have a higher density and can be used as part of a larger soundproofing system, which will ultimately help reduce noise transmissions through the ceilings.
- Fire resistance: Their sole purpose is to help increase the fire resistance of the area. Fire resistant plasterboards are manufactured from a variety of materials, including fire-resistant fillers and fibres.
- Soundproofing: Acoustic plasterboard is a great product designed for use in ceiling and wall lining. They offer higher sound insulation by absorbing and blocking soundwaves.
Plasterboards are designed to provide durability with a high-quality lining for walls and ceilings, as well as lift shafts and stairwells, and corridors and auditoria.
Our range of plasterboard products also includes coving, which is a strip-type of moulding that is typically used decoratively. Coving has a smooth surface and can be used to hide the join between the different coloured wall and ceiling, adding character to your rooms.
