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
  • Area under the cold water tank left clear so it cannot freeze
  • Eaves kept clear, with ventilation trays where air could be blocked

Questions about loft insulation in Dunbartonshire

Are your prices the same across Dunbartonshire?

Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.

Which council covers my address in Dunbartonshire?

Councils in Dunbartonshire include East Dunbartonshire and West Dunbartonshire. Your council matters for building control questions and some funding schemes.

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.

Will loft insulation make my loft colder?

Yes, and that is expected. The insulation keeps the heat in the rooms below, so the loft above runs closer to the outdoor temperature. That is why pipes and the tank are lagged as part of the job.
