If I want to fit new glass to a frame and don’t want to go for double glazing, what glass is going to be the best insulation?

 

Google mainly returns loads of results for secondary glazing, double glazing etc.  I did find a company called histoglass who have a special glass which is meant to be an improvement on standard glass, but cost for supply only of five panes was about a thousand pounds plus £800 delivery (from Germany).

 

 Any suggestions (other than go for double glazing)?

What do you mean a frame?

No I am asking about different types of glass.  Are there types of glass which give better thermal performance without being double glazed?

Not really, whilst coatings may reduce solar gains or losses etc.

 

A single pane of glass is just that, looking at the histoglas is it mono version ?.

Glass isn't a brilliant conductor, if you don't go for double glazing then without consulting any tables I think the best you can do is the thickest you can find.

Yes the product is mono rt+ which is claimed to have a thermal conductivity of 3.6 compared to standard 4mm glass of 5.6.

Appears to be a plastic film bonded to glass, not sure if it's just on one side or laminated like a windscreen.

 

Obviously it's a halfway between single pane and double or triple glazing.

 

If it was me I'd just go double or triple, probably a lot cheaper in the long term as the frame also forms an integral part of the thermal insulation.

Thank you for your replies.  I could go down the double glazed route I know.  It is only a porch and I don’t really feel it is necessary.  I just wondered if there is something single glazed which is a bit better than just plain glass.

 

I regard double glazing as a necessary evil for the rest of the house but to be avoided where possible.

My wife's aunt got some windows fitted recently in her utility room, she is what you might call extremely frugal so didn't want to run to the expense of double glazing but actually found double glazing was cheaper due to mass production.

 

I guess unless you're going to make the frames from logs and glaze with putty then your material cost will be lower than the finished items.

My detached non-heated garage has double glazing as it was way cheaper than trying to put single glazed frames in.
