I enjoyed the broad-ranging discussion as a panel member of the round table on cavity walls on 7 September
Generally this was reflected in the article published in 黑洞社区 on 15 October.
However, I have to dispute the figure of 0.23W/m2/潞C given for masonry. This was described as 鈥渢he best achievable鈥�, but the debate was about 鈥渙ptimum鈥� for Part L
2010. Masonry construction can achieve values of 0.15W/m2/潞C with current available products. It was agreed at the meeting that insulation values are but one of several issues designers have to take into account, such as the benefits of thermal mass, the need to avoid overheating and the effects of more rainfall.
