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
- 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 Denbigh
How do I pay for work in Denbigh?
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 Denbigh?
Not normally. Our guide prices include normal travel to Denbigh. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Is loft work in Denbigh different from anywhere else?
The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.
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.
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.
