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
- Mineral wool to 270 to 300 mm across the whole loft floor

Questions about loft insulation in Penarth
Do you charge extra to travel to Penarth?
Not normally. Our guide prices include normal travel to Penarth. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
How do I pay for work in Penarth?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
How soon can you visit a home in Penarth?
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.
How long does it take to insulate a loft?
Most lofts in houses take a single day. A large bungalow loft, a loft that needs clearing first or one with awkward access can run into a second day.
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.
