About this service
We lay the first layer between the ceiling joists and a second across them, so the floor of the loft is evenly covered to full depth. Eaves kept clear, pipes and tank lagged, cables on top, hatch insulated.
What’s included
- Loft measured and checked before we start
- First layer between the joists
- Second layer across the joists
- Eaves trays so air keeps moving
- Pipes and tank lagged, cables lifted on top
- Hatch insulated and draught-sealed
We price the job after looking at your loft. You get a written quotation before any work is agreed.
Two layers, laid crossways
Joists are usually around 100 mm deep, so one layer between them is never enough on its own. The second layer goes at right angles across the top, covering the timber and bringing the whole loft floor up to depth. For mineral wool, around 270 mm in total is what’s commonly recommended.
The bits that get missed
Insulation pushed into the eaves stops air moving under the roof, so we fit trays to hold it back. Pipes and the tank sit in a colder loft afterwards, so they’re lagged. Cables are lifted to sit on top. And the hatch is insulated and sealed, because it’s a hole in the middle of everything else.
Want storage too?
Boards laid straight on the joists squash insulation flat. If you want to keep using the loft, we’ll quote for a raised floor on legs at the same time.
