Can I buy single boards?
No. This product is sold in full manufacturer packs only. One pack contains 15 boards (43.2m²) and the price shown is for the whole pack.
How many do I need?
Divide the area to be covered (m²) by 43.2m² and round up, then allow around 10% extra for cutting and waste.
What are the delivery charges?
Free delivery to England on every order; minimum order £400 + VAT. Delivered by Moffett lorry (forklift offload); someone must be present to receive it. Delivered in England only. We do not deliver to Northern Ireland or the Scottish islands.
Where can I find U-values and installation guidance?

R-value = thickness (m) ÷ thermal conductivity λ, using the λ declared for each product, rounded down to the nearest 0.05 m²K/W. For insulated plasterboard the R-value shown is for the insulation layer only; the plasterboard adds a little extra. Always check the manufacturer's declaration of performance and your U-value calculation for Building Regulations.
