Browse Forums Eco Living Re: Heat loss through window problems 4Aug 06, 2010 9:55 pm Double glazing will cut down on direct solar gains compared to single glazing - perhaps up to 10%. However it will cut down conduction / convection heat losses by 33 to 50%. Therefore a net gain in winter and even better in summer to prevent heat gain. Heavy curtains with pelmets are a good additional heat flow retarder. Don't like pelmets - if you only have 2.4 metre ceilings could consider floor to ceiling curtains - the pelmet then is not so prominent incorporated into the cornice line. Otherwise I have heard suggestions of cellular blinds being good or else lined roman blinds where the top of the blind is flush against the wall and also the sides of the blind when down. (Care needs to be taken not to block winter solar heat gains with the blinds.) Must keep sun off glass in summer - eaves or other shading structure to North.

Re: Heat loss through window problems 9Oct 19, 2011 9:10 pm I have recently been to the Dowell factory in Bayswater where they have released the ThermLine range in both awning and sliding window formats. I met the designer and not only does the new profile look great but WERS have rated them as the best on the market. GJ Gardner are researching them very closely for some of their more upmarket homes in Mebourne Eastern suburbs. Re: Heat loss through window problems 10Oct 26, 2011 1:51 pm Local hardwood timber frames on double glazed windows provide no thermal bridging issues and are a far more environmentally sensitive choice compared to the all other options (such as PVC and Al), this is about sustainable building after all.....As Eccles rightly pointed out, it is most important to get your eve/solar pergoal design right to allow full solar access in winter and full shading in summer. Also allow for plenty of cross flow ventilation options in summer too. Steve There may be answers here but can't find anything. I have a closed in veranda, four windows.
