Gusty are you sure about the windows? I was at the point of giving up too, but Russell Timbertech DG worked out very similar in cost to my local uPVC supplier. And jeld-wen's basic "sovereign" range from the builders merchant is about half that, albeit a bit old fashioned looking.

Ah, fair enough. I've only had a limited number of quotes and require only half a dozen windows so the difference in overall bill is much smaller too.

Sorry, carry on!

I had a chat with the blokes at Albo today who reckon that using 3g on their windows only adds 4% to the cost. I ask them to give me a comparison with a normal 2g spec. We'll see the price difference when it comes but their prices do seem to be very reasonable.

They do good doors too.

There is a door thread about insulated doors on here. I found that IG doors in wales do steel and fibreglass doors with foam cores at relatively reasonable prices. Still about twice as much a basic UPVC door GBP 600-700 vs 300, but the most cost-effective of the well-insulated ones. If you don't need a lot of glass in your door they seems like good gear.

Slight hi-jack - anyone know of any companies providing 3g doors (we need the light!).

Many of the European window manufacturers do high spec (e.g. PassivHaus) fully glazed doors based on their window designs. The prices look pretty reasonable, even for someone like Internorm, especially compared to a solid PassivHaus door.

Might also be worth talking to Greensteps. They seem to have a good quality (PassivHaus) window product at a good price and can do glazed or custom doors to your design.
