As part of our technical services, we proudly offer a consultancy service to the National House Building Council (NHBC). We can draw on our vast knowledge of the rendering, plastering and construction industry, with experience in render and plaster application, bricklaying, house building, building control and site inspection. It is this experience and knowledge that the NHBC claims department have called upon time and time again when they require they require assistance with render claims.
Blue Mills render failure
Once a magnificent building in the heart of Fowey, Blue Mills fell foul of poor design features and a lack of consideration for the movement of the timber frame structure. The NHBC claims department once again sought the expert advice, consultancy service and technical knowledge of SAS in order to identify the cause and rectify the issues with the Blue Mills failing render system. Following minor exploratory work, it soon became clear that movement, an integral part of any design consideration for timber frame construction, had become an afterthought, along with inadequate size, layout and fixing of the timber battens.
Replaced with ProWall
A schedule of works was agreed between SAS and the NHBC to replace the failed system with ProWall our rendered rainscreen cladding system. This project emphasises the importance of considering all aspects of movement, shrinkage and detailing at the design stage and during application when choosing a rendered rainscreen cladding system. ProWall achieves this with a complete system backed with expert technical advice and site visits from initial design to project completion. A case study regarding the claim can be downloaded here.
