some cases this could be over 100 kg/m2 that gives a freedom of design without drawbacks – e.g. no need to choose between a large, fl oating washstand and the natural stone fi nish of the wall. In 2025, compliance with the Future Homes Standard will also become mandatory; all new homes built from this year are to be future-proofed with world-leading levels of energy effi ciency. Low carbon heating encouraged to reduce emissions to 70-80% less than previously accepted.
While directly tileable waterproof building boards may not directly tackle such challenges, thanks to the low U-value, they also contribute to the thermal insulation of the room from the inside, and therefore to the energy effi ciency of the home – this makes them perfect to use beneath under-tile- heating (UTH) systems of all kinds. It is also worth mentioning, that some manufacturers offer these boards with factory-cut, precise grooves that not only greatly reduce the risk of the pipe runs being accidentally damaged but also ensure the even placement as close to the surface as possible – ideal to use with heat pump operated water-heating systems under the fl oor or behind the wall. Directly tileable XPS boards and shower formers hold all required certifi cates to
comply with NHBC’s new guidance; from Environmental Product Declarations (EPD) and an A+ VOC label, through BBA certifi cates and a European Technical Approval (ETA) marked to EAD 030437- 00-0503, to CE, UKCA and UKNI marks. It is also worth noting, that using waterproof building boards together with clever accessories and interlocking components – such as fl oor-level shower elements, benches, niches and ready-to-use partition walls – provides a fl oor-to-ceiling, systemised waterproofi ng solution that, when installed correctly, lasts the lifetime of the building. Finding a manufacturer who, besides directly tileable waterproof elements, can also provide compatible grouts and adhesives that fulfi l the above discussed
requirements, is not at all impossible. Imagine; everything beneath the tiles from a single source – one manufacturer means one responsibility and of course, one point of contact for planning, construction and for any issues. So, ultimately, there are two distinctive routes to comply with NHBC’s new technical guidance. One takes you on a journey of complex research during planning, then requires careful time and personnel management during the construction phase if the project is to be completed on time. While the other offers a quick and straightforward installation with signifi cantly less personnel and installation steps being required, and can minimise the risk of failure; simply put, it creates the conditions under which other solutions can be adopted easier and faster. The focus is on energy effi cient future-proof bathrooms, the importance of which our industry is only just beginning to realise. Now more than ever, it is crucial that we implement complementary innovations together; it can provide far more signifi cant outcomes than implementing them in isolation. Streamline the construction process and stay focused on the design.
