What is sheep's wool or natural loft insulation?
Sheep's wool and wood fibre are vapour-open and can take up and release moisture. The trade-off is cost: natural materials usually cost two to three times as much as mineral wool for the same performance. More about sheep's wool or natural loft insulation.

How much does sheep's wool or natural loft insulation cost in Potters Bar?

Questions about sheep's wool or natural loft insulation in Potters Bar
Can a landlord in Potters Bar book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Do you take on jobs outside Potters Bar?
Yes. We also work in Borehamwood and Hatfield and elsewhere in Hertfordshire.
Can you visit Potters Bar outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
How deep does natural insulation need to be?
It depends on the product's thermal conductivity. Some need slightly more depth than mineral wool to reach the same U-value, which we allow for on the quote.
Is sheep's wool insulation worth the extra cost?
In an older breathable house, or if you care about the material, often yes. In a modern semi with plasterboard ceilings the extra cost buys little performance.
