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.

Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.

We measure before we quote

Existing depth, joist spacing, wiring and the tank are checked, not guessed.

Eaves kept clear

Insulation is held back from the eaves so the loft can still ventilate.

Questions about loft insulation in Southampton

Do you take on jobs outside Southampton?

Yes. We also work in Hythe and Totton and elsewhere in Hampshire.

Will I get a written quote for work in Southampton?

Can you visit Southampton outside working hours?

How deep should loft insulation be?

The Energy Saving Trust recommends at least 270 mm of mineral wool, and that is the depth we install as standard. Building regulations also set an energy standard for the roof when a loft is insulated. It differs between England, Wales, Scotland and Northern Ireland, so we confirm the target for your address on the quote.

Do I need to empty my loft first?

The floor needs to be clear for the insulation to go down. If moving things yourself is difficult, tell us at the survey and we can price clearing and putting items back on raised boarding.
