    Insulation - heat transfer

    For maximum insulation in a small thickness go for a mutilayer material. It has several layers of aluminium foil separated by thin layers foam. It's quite expensive to insulate large roofs but a little piece for your job wouldn't cost much.

    glasses specific evaluation Help

    Thankyou, Breezer, for brightening my day. I carve a hole in the wood and then stick a piece of glass in to keep the elephants out. It works. I can see out and there are no elephants in my house.

    misty windows

    Getting the mastic off the glass will be a very difficult job. You will probably decide to fork out for a new unit before you finish the job. Sadly, stuffing Prescott and replacing with single glazing are both illegal actions. :-)

    glasses specific evaluation Help

    >100% Virgin Vinyl - Will never peel, chip, flake, crack or fade 'never' is a rather grand claim for anything plastic. Even the 'Lifetime Material Warranty' is suspicious. I wonder whose lifetime they are referring to? Wooden windows are so much better.

    Wooden window treatment

    It depends a bit on what sort of wood it is and if it has been treated before. If it's oak you don't need to do anything except enjoy the appearance of weathering oak. Or you could coat it with linseed oil if you prefer that sort of look. If it's larch or Douglas fir then linseed oil paint is...

    Tung Oil on stained windows

    I find there is a subtle difference between linseed and tung oils. The tung soaks in leaving the surface of the wood more 'natural' whilst the linseed, at least after the third thin coat, forms more of a varnish like layer on the surface. So I tend to use linseed on the outside of my oak...

    Screed Floor - Quantities of Sharp sand and Cement

    Just step back a moment and ask, Why use cement? You can make a perfectly good floor with a sand and lime. Lime takes less energy to make than Portland cement and absorbes carbon dioxide from the atmosphere as it sets. It is less damaging the to the planet than cement. Cement's greater...

    Replacing Wooden windows with UPVC double-glazed

    I usually use linseed oil on the outside and tung oil on the inside of oak windows but leaving it bare is fine too. The surface goes silvery-grey and a bit rough but that is very superficial. If the wood has crumbled there must be something else amiss. Larch is the most easily obtainable...

    Replacing Wooden windows with UPVC double-glazed

    My oak windows are a little more expensive to buy than a plastic one but I would expect them to last 250 years rather than 25. _____________________ moderator please note 9

    Sealing DG window units.

    If the dg unit is bedded in silicone then when the silicone-wood and the silicone-glass junctions fail, water can get in and be trapped. This increases the danger of the dg unit's seal failing with resulting misting up. If the unit is held into the wooden frame with double sided glazing tape...

    Installing double glazed panes into old frames?

    Remember that the old glass, complete with its distortions, is a historic fabric. Please don't destroy it. It is very valuable. You could be seriously reducing the value of your property if you remove it. If it were a listed building you would be committing a criminal offence. The 'P1'...

    wood window frame DG rebate size?

    The ideal air gap from the heat insulation point of view is about 16mm. With two sheets of 4mm glass that makes a 24mm unit. Allow 2mm either side for glazing tape and a 12mm bead to hold it all in and you find you need 40mm. In the other direction you need about 12mm to cover up the spacer...

    Replacing Wooden windows with UPVC double-glazed

    The paint that Holkham sell is actually manufactured by a Sweedish company called Allback. It is excellent paint. The binder is linseed oil and the pigment is titanium dioxide, not lead carbonate as that is too poisonous. The real beauty of linseed paintis that it remains 'breathable' alowinf...
