How delivery works

We work with a nationwide network of trusted suppliers. Items in your basket may be supplied by different suppliers and delivered separately. Where this applies, you will see delivery charges shown at checkout for each part of your order. We always aim to group products from the same supplier to keep delivery costs as low as possible.

Delivery areas

Delivery charges apply to mainland UK, excluding: AB, CA, CF, DD, DG, EH, EX, FK, KA, KW, KY, IV, LA, LD, LL, ML, NP, PA, PH, PL, SA, SY, TR, TQ and TD.

If your address is in one of these areas, we will contact you before processing your order to confirm any additional costs. We do not currently offer delivery outside the UK mainland.

What to expect on delivery day

  • Deliveries are typically kerbside.
  • Please ensure someone is on-site to accept delivery. For heavier items, help with offloading may be required.
  • Many building materials arrive on large vehicles. If access is restricted, a specialist vehicle such as a HIAB may be required and could incur an additional charge.

Why delivery can cost more than typical parcel delivery

Building materials often travel on larger vehicles and usually carry fewer drops per run than parcel networks. That is why delivery charges can be higher than standard e-commerce shipping.

Returns

Returns depend on what you have bought and whether there is anything wrong with it. For full details on eligibility, timeframes, and exclusions, please see our full policy.

What Is Ecotherm 100mm Cavity Insulation? 

100mm EcoTherm Eco-Cavity Wall Insulation Board is a partial fill cavity wall insulation solution designed for brick and block masonry walls. 

With a thermal conductivity of just 0.022 W/mK, it brings the thermal benefit of PIR insulation as well as aluminium foil facings on either side that prevent radiated heat from being passed through the air space.

Ecotherm 100mm Cavity Insulation boards are specifically designed to work in conjunction with traditional wall tie spacing and can be used both in new builds and extensions of existing properties. Like other UK-manufactured PIR insulation, they also carry BBA certification.

What's more, 100mm Eco-Cavity boards are manufactured with a CFC/HCFC free blowing agent, making them environmentally friendly. 

The boards are sized at 1200mm x 450mm, and come in plastic wrapped packs with multiple boards in each.
