I am insulating the walls and ceiling of a 6m x 3m breezeblock construction outbuilding for my father in law in Scotland that has a flat roof with previously no insulation and no soffits. The roof just covers the width if the walls with no overhang. It has double glazed windows and door. We...

1st valve lasted 7 or 8 years. Second one 2 years. Now another one on a different zone is opening but not sending a live switch signal out. Worked around it by sending the thermostat -on live signal to the boiler so dont need valve microswitchbto work. Any advice on getting valves to last...

In support of elevonic. Bought a new mixer tap at IKEA. Pipe tails and the rest were exactly the same AND had flexible tap connectors so no need to move anything. The IKEA instructions DIDNT say you needed a box spanner. After an unpleasant WTF half an hour under the sink I found this...

Thanks for all the replies. I am using spanish new slate 14 x 8's. They seem to be going on easily enough Local authority are totally fine with the roof - it is not a requirement just a custom! You havent answered my main question though so I will try and rephrase? How do you repair...

hi I have put up a cold unvented unsarked roof in scotland ie no boarding or sheeting but battens and counter battens over breathable membrane. The slaters who have looked at it up here all complain cos they say it is much harder roof to work on as they cant drive their supports for planks...

yes they have give a warrant to the plans. mind you many people just assume there are sarking boards on it - ity is only when you look closely that you realise there aren't. I don't see why scottish building control would insist in it? tommy b.
