Loft Insulation and Boarding in Nottingham: Raised Deck Over New Wool
Old insulation out, new wool in, and the loft boarded out on raised legs so the deck sits clear of the insulation instead of flattening it. The same approach as our Leeds job, in an older roof with less room to work in.
Old insulation cleared before anything new went down.
New mineral wool laid across the joists, then raised legs set into it.
OSB boarding fixed on top of the legs, leaving the insulation uncompressed beneath.

The problem with boarding straight onto joists
Most lofts that already have boards have the same fault: the boards went straight onto the joists, which squashes whatever insulation is underneath them down to the depth of the timber. The homeowner gets storage and quietly loses insulation performance in the rooms below.
If the insulation is going to be at current depth, the deck has to sit above it.
What we did
The old insulation came out first, and new mineral wool went down across the joists. Raised legs were then set through the wool onto the joists, and the boarding fixed on top of those.
That leaves a gap between the underside of the boards and the top of the insulation, so nothing is pressed flat. The second photograph shows it clearly: the boarded deck sitting proud with the full depth of wool intact underneath.
The result
A flat, walkable storage deck with the hatch and the walkway left clear, and the insulation doing its job underneath rather than being crushed by the floor above it.
What we do
Three jobs, done properly, by the same team
No subcontractors sent out in our name. The surveyor who quotes it sets out the work, and the lads who turn up are ours.
Spray Foam Removal
The most common reason people call us: a mortgage lender or surveyor has flagged spray foam in the loft and the sale has stalled.
