Questions about sheep's wool or natural loft insulation in Derry/Londonderry

How do I pay for work in Derry/Londonderry?

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.

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.
