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.

  • Eaves kept clear, with ventilation trays where air could be blocked
  • Tank jacket and pipe lagging in the loft
  • Cables lifted clear of the insulation where possible

Questions about loft insulation in Ruthin

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

Do you charge extra to travel to Ruthin?

Not normally. Our guide prices include normal travel to Ruthin. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

Can you visit Ruthin 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.

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.
