Thought I'd post some photos of my loft "conversion", might fill you with a bit of inspiration and to share some ideas. Moved into this place in January, loft had old steel c/w tank (disconnected) and an concrete asbestos tank, both have been removed and a 75 gall poly tank installed. New loft ladder shown in another post. Bulk of the work has been in boarding and insulation this space, its going to be used just for storage as head height is limited, roof pitch is 30 degrees. Joists and rafters are 3"x2", so I battened these out with 45mm x 45mm treated timber and fixed using No.10 3.5" screws. 100mm of Knauf Earthwool is going between the joists, 70mm Quinn Therm between the rafters (sitting against 19x38 battens to provide 50mm air gap) and then covered with Airtec double to provide a VCL. So the loft space pretty much becomes part of the house. I reckon these 3 types of insulation combined brings the total value to around modern days specs. Work in progress a short while back, you can see the QuinnTherm and battening in the roof, floor has been battened and boarded, cold water tank in place. I made up these airetc "pockets" to go into the eaves for extra insulation and better seal this area from the outside, as the QuinnTherm was difficult to cut/shape so low down. Pop them in place, later they get stapled and foil tape over the joins Here you can see the pocket in place and there's another layer over it from the airtec on the rafters, Knauf Earthwool being laid. All nice and airtight, super cosy. One half is now all done, flooring is screwed down. Now working on the airtec pockets on the other side, the area behind the water tank is inaccessible, will need to remove the tank for this, as a last step.
