Natural, Sheep’s Wool and Itch-Free Loft Insulation: What IWD Stocks
Search interest in sheep’s wool, “eco” loft insulation and itch-free alternatives is high. Here is an honest stock position from Insulation Warehouse Direct, plus the mineral-wool and PIR options we do sell for lofts.
Quick answer
We do not currently stock sheep’s wool, hemp, wood-fibre or branded “itch-free” polyester loft rolls such as some specialist natural ranges. What we do sell for lofts is glass mineral wool loft roll (including Knauf Insulation Loft Roll 44), stone wool options in our Rockwool and related ranges, and PIR boards where a boarded loft or rafter detail needs rigid insulation. If you specifically need sheep’s wool, you will need another supplier; we will not pretend otherwise.
Why people ask for natural or itch-free loft insulation
- Comfort when handling (less skin irritation than some glass wools).
- Preference for renewable or bio-based fibres.
- Breathability claims in older or solid-wall homes (always check the whole build-up).
Glass mineral wool remains the most common UK loft top-up because it is widely available and cost-effective at the thicknesses used for cold lofts (see 270mm loft insulation guidance). Wearing gloves, long sleeves and a dust mask makes standard loft roll manageable for most DIY jobs — see how to insulate a loft.

If itch is your main concern
Use PPE with standard loft roll, or choose a product marketed as low-itch from a specialist supplier if that is essential to you. We would rather send you to the right place than sell you the wrong story.
Frequently asked questions
Do you sell Thermafleece or similar sheep’s wool?
Not at the time of writing. Check our loft insulation collection for current mineral-wool stock.
Is Knauf loft roll itch-free?
It is glass mineral wool — use gloves and long sleeves. See the product datasheet for handling advice.
Can PIR replace loft roll?
In a cold loft, mineral wool over joists is the usual route. PIR is more common between rafters or under boarding — different detail.
Do you install insulation, do surveys or help with grants?
No. Insulation Warehouse Direct sells insulation materials online. We do not install insulation, carry out surveys or handle grant applications. If you want it fitted, use a qualified installer, and for grants check the official GOV.UK energy schemes. We are happy to supply the materials your installer specifies.
