Questions about sheep's wool or natural loft insulation in St Austell
Is loft work in St Austell 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.
Do you cover all of PL25?
Yes, we cover the PL25 postcode district and the districts around St Austell.
Do you take on jobs outside St Austell?
Yes. We also work in Bodmin and Truro and elsewhere in Cornwall.
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.
