    UFH pipe brands and controls, any to avoid?

    have a look at www.ufhtradedirect.co.uk to compare prices. Pert Al Pert are much easier to lay as they hold their form. i've used the manifold from the above site and they are of very good quality.

    Could this house be extended?

    lol @ the gas pipe that overhang does look quite scary, can't quite work out what's holding it up (the plastic windows??). i wonder if it would hold if there's a few inches of snow on there.

    Sound proofing - Double or Triple and what type of glass?

    most of the external noise is transfered through the frame rather than through the sealed glass units. go for wooden frames instead of pvc. the quality of the installation is just a important. large gaps filled with silicon between the frame and the wall lets quite a bit of noise through...

    bi fold patio doors support...?

    sliding doors are bottom hunged agreed but bi-fold doors are top hung. bi-fold doors are a lot heavier than sliding. being top hung makes them a lot easier/smoother to open/close. i've had 2 installed - a 12 and 6 ft.

    Underfloor heating without the heat

    Maximum door opening width - french door options!

    i must also point out that those doors are 'top hung' which means you have to factor the weight in when speccing your lintel.
