Is it beneficial to have secondary double glazing or would single glazed units be sufficient?
Does the gap between the panes matter (when its more than 16mm), say as much as 100mm?]]> Secondary glazing/double glazing http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=60&Focus=608#Comment_608 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=60&Focus=608#Comment_608 Thu, 22 Feb 2007 08:45:36 +0000 biffvernon
If the important thing is maintaing external appearance, then secondary glazing can be sufficiently discrete not to detract from that appearance. Gaps beyond around 20 mm allow convection which significantly reduce the thermal resistance of the window, though may improve sound insulation.

In a building whose interior is of special historic significance, the internal appearance of secondary glazing may be unacceptable. In such a case the use of other energy saving measures may be given a higher priority.]]> Secondary glazing/double glazing http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=60&Focus=625#Comment_625 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=60&Focus=625#Comment_625 Fri, 23 Feb 2007 12:13:56 +0000 fostertom http://www.greenbuildingforum.co.uk/forum/index2.php?DATEIN=tpc_hnovqhocr_1163970597&LP=true]]> Secondary glazing/double glazing http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=60&Focus=626#Comment_626 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=60&Focus=626#Comment_626 Fri, 23 Feb 2007 12:46:14 +0000 tony Secondary glazing/double glazing http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=60&Focus=627#Comment_627 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=60&Focus=627#Comment_627 Fri, 23 Feb 2007 13:05:09 +0000 fostertom Secondary glazing/double glazing http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=60&Focus=629#Comment_629 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=60&Focus=629#Comment_629 Fri, 23 Feb 2007 16:59:48 +0000 tony
