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 Cobham
Is loft work in Cobham 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.
How do I pay for work in Cobham?
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 Cobham?
Not normally. Our guide prices include normal travel to Cobham. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
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.
