An insulation merchant without the branch

We trade online only. There is no trade counter and no collections from our unit in Sileby, Leicestershire, which is open to visitors by appointment. Our team has over 20 years’ experience in the specification, manufacture and distribution of insulation and dry lining. We work with some of the UK’s largest manufacturers and suppliers, with more than 100 distribution points to supply from. Our aim is to be the cheapest insulation and dry lining supplier without cutting the service: we don’t sell cheap insulation, we sell quality insulation at low prices.

Delivery

Delivery is kerbside, Monday to Friday, on 26 to 32 tonne lorries, so someone over 18 needs to be there to sign and the load needs flat, even ground to come off on. It is free on orders of £500 or more ex VAT. Each product page shows its own delivery time. Parts of Scotland, Wales and Cumbria, Northern Ireland and the islands are outside our standard area, so check the delivery information before you order.
