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.

Questions about sheep's wool or natural loft insulation in Barnet
Do you charge extra to travel to Barnet?
Not normally. Our guide prices include normal travel to Barnet. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Will I get a written quote for work in Barnet?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Can you visit Barnet 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.
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.
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.
