Browse Forums Windows & Doors 1 Jul 14, 2010 2:15 pm Due to budget constraints when building, double glazing wasn't possible. Some might say short sighted and I might agree to a point but you can only spend so much. Anyway, I'm not overly impressed with the performance of the ducted heating downstairs. This is mainly due to ceiling mounted vents not being in optimum positions (ie in front of the windows!) The main problem room is the lounge, where the vents are approx 2m from the wall with the windows. This was due to having steel beams supporting the upper floor and preventing any ductwork being run to the appropriate location. Adding to the issue is the room being a drop down step so the top half of the room is nice and warm but the bottom half is average. I have combating this as best as I can by reducing vent openings in the back half of the lower floor and adjusting angles etc so it forces a bit more air into the lounge and reaches pepple sitting on the couch. But unless the unit is running constantly the room feels cold fairly quickly. It also gets no afternoon sun so I can't leave blinds open during the day to assist there. I was wondering if there was some film I can put on the glass to assist. While the roller blinds offer a noticeable difference with heat loss (opening the one at my slide door results in the room cooling quite quickly), there is still a gap around the sides so I'm thinking there is more gain to be had? Re: Low E or similar window film to reduce heat loss? 2Jul 16, 2010 8:25 am Double glazing and Low-E work differently. You really needed double glazing as it would stop conducted heat. Right now, other than changing your windows you can only shield the windows with curtains and blinds. Changeover I think maybe three times the cost of good curtains and blinds (guess) Ed "ECOECO" At 'EcoEco', we design windows, we design the best windows, we do it for you, so that when you’re happy we are happy.

If not block off stairs - with curtains or doors. There are secondary glazing systems out there - magnetite and ecoglaze etc - as alternative to double glazing but still quite expensive. You could also consider a ceiling fan to distribute the heat more evenly, especially to the lower level part of the room. Cooling benefits in summer as well.

Dearer than replacement double glazing IMO, and add less value. Ed "ECOECO" At 'EcoEco', we design windows, we design the best windows, we do it for you, so that when you’re happy we are happy.

Suppose it depends on the type and condition of your frames? With timber maybe a chance, with aluminium almost zero.

I know this one will help heaps as the lounge is opp the stairs and can feel significant heat being drawn past when standing in front of the balustrade. I'd have to hang some type of curtain and pull it down when not required. I did think about how to block the area off but never thought of a curtain or blind. I haven't come up with a temporary measure to test it out though. Eccles You could also consider a ceiling fan to distribute the heat more evenly, especially to the lower level part of the room.
