<b><b>When it comes to complying with new thermal regs, don't dismiss the idea of external wall insulation. Gillian Allder, chairman of the Insulated Render &amp;&amp; Cladding Association, explains </b></b><br><b><b></b></b><br> To satisfy the needs of the new Part L, the Insulated Render &amp;&amp; Cladding Association is promoting construction designs which achieve the &amp;"heat sink&amp;" 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. <p></p><p><b><b><b>Insulated render </b></b></b><br> 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. </p><p><b><b>Change in thinking</b></b><br> New build design using insulated renders and claddings may necessitate …
