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 Porthmadog
Is loft work in Porthmadog 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 take on jobs outside Porthmadog?
Yes. We also work in Pwllheli and Caernarfon and elsewhere in Gwynedd.
What do I need to do before you arrive in Porthmadog?
Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.
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.
Do moths eat sheep's wool insulation?
Insulation-grade sheep's wool is treated against insects. We use products sold for loft insulation, not raw fleece.
