To satisfy the needs of the new Part L, the Insulated Render & Cladding Association is promoting construction designs which achieve the "heat sink" benefits of insulated renders and claddings. These place the insulation in the most effective position within the outer skin, so maximising energy retention and resistance to external temperature extremes.
In readiness for the new requirements, forward-looking builders will undoubtedly be looking at the most economical and energy efficient construction methods. Solid block construction using insulated render or cladding as a simple energy efficient new build method is already well proven and demand continues to increase. It is a simple process that, added to concrete block or framed construction to form a solid wall, can go up faster than traditional building - yet still retain the traditional external appearance. It can lead to prestigious-looking buildings, with high energy efficiency, low running costs, and a comparatively short construction time, with attendant cost savings.
