In this post, I’m not blogging about conservatories, but windows – A Rated Windows and the condensation problem they cause.
I have seen quite a few comments scattered around the double glazing blogs and forums from consumers complaining about condensation on A Rated Windows and Doors.
Apparently, the condensation forms on the outside of the glass due to the fact that the double glazing units that now have to be installed in all windows have greater thermal properties to comply with the new building regulations that came in to force on 1st October 2010.
The glass specification is basically soft coat, argon filled double glazed units fitted with a warm edge spacer bar.
On a positive note, A Rated Windows are doing the job that they were specified to do, which means warm air is prevented from getting through to the outer pane of the glass unit, but consequently this leads to condensation on the outside of the glass.
I think this is a real problem for the customers in that it creates an unpleasant environment within their homes, especially in the mornings. It seems to me that it is a major unforeseen problem that has taken the double glazing industry somewhat by surprise.
Condensation on A Rated windows is not the fault of the window industry in any way, it has been forced up on them by strict new building regulations which are governed by law.
However, no matter what, the external condensation on A Rated windows, which may even occur on lower energy rated windows is still a problem for the householder. This is a real problem that needs to be addressed by the building regulations, and urgently.
The problem won’t go away and the longer it is ignored, the more A Rated windows will be installed and the more condensation problems will arise.
I welcome all comments on this subject.
