H+H Celcon claims its aircrete blocks have highly insulating properties
H+H Celcon’s aircrete blocks were chosen for a new-build development of energy-efficient homes in Ratby, Leicestershire, which meet level four of the Code for Sustainable Homes. The firm claims H+H Celcon Plus Blocks were specified for their highly insulating properties. Cavity walls with traditional mortar using 3.6N/mm2 H+H Celcon Plus Blocks (610mm x 215mm face size and 100mm thick) were used for the external walls, with a 200mm-wide filled cavity wall achieving a U value of 0.13m2K/W. The company says the traditional two-coat wet plaster to external walls has helped achieve air-pressure test results of below 5m3/hr/m2.
