I'm almost ready to lodge Town Planning.
I would like double glazed windows throughout the house to sustain a reasonable heating and cooling bill. To suit the Neo Georgian style of the house what sort of windows frames and openings should I be looking at, casement, awning ? I notice a lot of these style houses have timber on the facade and alum elsewhere. On this the site, the advise is, ask for 12mm gaps. Is it a lot more expensive to have arched windows?, I would like to have them on the 1st floor facade.Window size is 90cm x210cm
