Footings & Foundations Phase1 Performance plasterboard Etex Building Performance UK 25 Performance plasterboard: Spring 2018 the secret to a comfortable home Robert Cridford, technical manager at Etex Building Performance UK, explains the importance of performance plasterboard for creating the perfect home, and the key things you need to know to pick the right board for you Choosing building products is always a challenge: you want your first pick to be the right one. The cost of selecting the wrong material for the job can be significant, leading to costly repairs or alterations down the line, as well as causing homeowners to miss out on the potential performance benefits that the right material would bring. As the main component of walls, ceilings and sometimes external façades, drylining materials such as plasterboard are a prime example in this regard. Plasterboard can significantly improve a building’s longevity and performance in terms of thermal efficiency, acoustic performance and resistance to humidity – helping you to create a comfortable home, which will stand the test of time. So where should you start your search? First of all, it’s vital to understand the range of different products on offer, and why some boards are better placed than others, depending on what room you’re looking to use them for, and the performance criteria you need to meet. Here are the key technical differences and applications that you should be aware of: Thermal boards High-quality thermal boards are key to keeping your home warm and reducing your energy spend. Thermal boards are ideal for insulating areas, which traditionally are a major source of heat loss such as garages and cellars, as well as lofts to prevent heat escape from the top of a property. Up to 46 times more efficient than standard plasterboards, they can dramatically reduce a home’s energy use, bringing both environmental and financial savings. They are also important for meeting U-value requirements specified under Building Regulations, which differ depending on whether your project is a newbuild, change of use, or renovation scheme. Water resistance Standard plasterboard absorbs water at a rate of over 20%, making it unsuitable for high-humidity environments like bathrooms, wetrooms or kitchens. For these areas, specialist waterresistant boards are available. They have a non-paper liner and include additives such as silicone to repel water and biocide additives to help prevent mould growth. Thanks to these additions, they have a water absorption rate of less than 3%, helping to minimise expansion cracks and prolonging the durability of a wall or ceiling. Acoustic performance Whether you want to block out the sound of noisy neighbours, or turn your music up loud, acoustic plasterboard is vital for improving a home’s sound insulation. Denser than normal boards, acoustic boards can help to cut out 30% more noise than standard products. Achieving maximum acoustic insulation relies as much on the performance of an overall system as on the board itself, so it is also important to use the right tracks, studs, cavity insulation and sealants. www.etex-bp.co.uk
