The new Monocouche Best Practice Guide by Saint-Gobain Weber provides technical information on the management of movement in new build housing which ultimately can be the cause of cracking in render.<br> <br> Although cracks in render are not hazardous to the integrity of the building, they reflect poorly on site workmanship. By following the best practice detailed in this guide, designers, site agents and contractors can achieve and maintain a flawless finish, Weber says.<br> <br> Saint-Gobain Weber Monocouche renders, which are manufactured at UK production facilities in Bedfordshire, Shropshire and Ballyclare, Northern Ireland, use carefully selected and graded aggregates to minimise drying shrinkage of the applied render.<br> <br> Weber says that it is the only manufacturer to produce BRE A+ Green Guide-rated through-coloured Monocouche renders, weber.pral D and weber.pral M which contain One-Coat Technology. Specification of these low maintenance, durable and highly weather resistant renders will help designers to meet mandatory requirements and achieve more materials credits in a Code for Sustainable Homes assessment, Weber explains.
