Insulating an outbuilding

Adrian · 2014-04-12T13:38:25+00:00

We've finally got a new roof on the studio building - corrugated metal sheet replacing asbestos cement. It's a reasonably large outbuilding, about 5m x 9m, and split into two rooms internally. The roof is currently plasterboarded on the inside of the slope, roughly 2.5m to eaves, 4m to apex. The walls are all block construction, and it probably dates back to the '60s. There's power and water, and a woodburning stove at one end. The roof's insulated with the usual fluffy stuff, fairly well-packed but not absolutely rammed in. It's probably contemporary with the rest of the building. We'll be replacing the plasterboard currently forming the ceiling, probably with wood t'n'g. The new roof has four translucent sheets, full length from apex to eaves, for light. So... what would you do to insulate it all? We'd like it to be fairly usable all year round, but won't be living in there. The render on the front wall (south facing) needs patching, the others are still in scratch-coat, but we'd ruled out external cladding anyway, and now the roof's done, there's not really enough overlap. The walls on the inside need plenty of TLC, so everything's in play there. The woodburner's flue is fairly close to that wall - not much space to put anything behind it. Budget is not unlimited, obviously.

Great content and information sharing by you as always. But i want to know about the insulation process of Liquid Roof Coatings? Do you have any knowledge regarding this?

Nope not much - never used it.

However I would suggest avoiding that particular supplier since:

1) They are US based and hence of no relevance here. 2) They have a reputation for posting spam to newsgroups using planted questions 3) Their marketing folks apparently don't know what the installation process is for their own product.

Surely insulation and roof finish are 2 separate things?
