Loft insulation between the joists under trussed rafters

Loft Insulation · Kent

Loft insulation,kept warm and kept full depth.

Heat rises, and a thin or worn-out layer of loft insulation lets it straight out through the roof. We replace old insulation and top up what’s there, and if you’re boarding the loft we’ll make sure the two work together.

Top-ups and replacement

Old insulation can settle, get dirty or get pulled about over the years. We’ll look at what you’ve got and either add to it or take it out and start again.

Done with boarding in mind

Boarding straight over insulation squashes it. If you want storage too, we fit raised timbers so the boards sit above the insulation rather than on it.

Ventilation looked after

A loft still needs air moving through it, or you risk condensation. We keep the eaves clear so the roof can breathe.

Other services

How deep should loft insulation be?

270mm is the recommended depth for mineral wool. Many older homes have far less, so it’s worth checking.

Can I board over my insulation?

Yes, as long as the floor is raised above it. We use raised timbers so the insulation keeps its depth.

Can you take old insulation away?

Yes. If yours is worn out, we’ll remove it and replace it.
