I'm planning to insulate my brick workshop outbuilding so I can use it in the winter.
The workshop is brick built with a flat roof and concrete slab floor. It has a damp course in the wall and possibly under the concrete, though I'm not 100% on that. A friend has a load of 25mm thick polystyrene insulation, so my plan is to do this.
Floor: DPM up to damp course line on walls, followed by polystyrene, then a floating chipboard floor on top of that.
Walls: Batten with 47mmx50mm and use the poly insulation between the battens, then foil backed plasterboard over the top:
Ceiling: Polystyrene or rockwool, then plasterboard.
Though I have a couple of questions.
1) What do you do first, the floor and ceiling, or the walls? Does it matter?
2) On the battens, do I just run them vertically, or do I have to do 'noggins' at the bottom and top?
