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 finished depth sits at 270 mm or more, the depth the Energy Saving Trust recommends. More about loft insulation.

  • Eaves kept clear, with ventilation trays where air could be blocked
  • Area under the cold water tank left clear so it cannot freeze
  • Tank jacket and pipe lagging in the loft

Questions about loft insulation in Antrim

How soon can you visit a home in Antrim?

We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.

Do you cover all of BT41?

Yes, we cover the BT41 postcode district and the districts around Antrim.

Do you take on jobs outside Antrim?

Yes. We also work in Ballymena and Newtownabbey and elsewhere in County Antrim.

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.

Does loft insulation need building control approval?

On its own it usually does not, but the work still has to meet the energy standard. The rules differ across England, Wales, Scotland and Northern Ireland, so we confirm the position for your address on the quote.
