I have a very small loft (4sqm) that is part of an extension that sits above a utility room between my home and garage. I would like to turn the loft space into a small server closet due to a lack of suitable location in the house. Due to this, I would like to somewhat insulate the loft space to keep it warm in winter and cooler in summer to stop my equipment going kaput.
I have attached some images that hopefully give you an idea of what's going on.
As you can see, the three walls in the loft are not external, so I am hoping there won't need to be any work done there. It is mostly the roof I am concerned about. To make clear, I don't intend for this to look like a nice space, my hope is to put simple loft boards down on the joists, insulated and plywood the roof area, and start screwing into the wall to hold equipment. I guess my questions are as follows;
- Can I safely insulate between the rafters, or will this cause damp issues? Do I need to leave a gap? I have attached pictures of the membrane below the tiles, is this breathable?
- If I insulated between the rafters, how do I close up the gap towards where the rafters meet the wall plate?
- Do I then need to apply a moisture barrier over the insulation?
- Do I need to put anything on the brick walls, or can they stay as-is?
- Is there anything I have overlooked?
Many thanks in advance :)
