What is loft insulation?

We lay the first layer to the depth of the joists, usually 100 mm, so it fills each bay edge to edge with no gaps. The second layer goes across the joists at right angles, which covers the timber and stops it acting as a cold bridge. More about loft insulation.

  • Cables lifted clear of the insulation where possible
  • Mineral wool to 270 to 300 mm across the whole loft floor
  • Tank jacket and pipe lagging in the loft

Questions about loft insulation in Portslade

Do you take on jobs outside Portslade?

Yes. We also work in Brighton and Rottingdean and elsewhere in East Sussex.

How do I pay for work in Portslade?

Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.

Do you cover all of BN41?

Yes, we cover the BN41 postcode district and the districts around Portslade.

Can you insulate around downlights?

Recessed downlights need clearance or a fire-rated cover so they do not overheat. We fit covers where needed and leave a clear zone around fittings that cannot be covered.

How long does it take to insulate a loft?

Most lofts in houses take a single day. A large bungalow loft, a loft that needs clearing first or one with awkward access can run into a second day.
