How many do I need?
Divide the area to be covered (m²) by 60.48m² and round up, then allow around 10% extra for cutting and waste.
What are the delivery charges?
Free delivery to England & Wales on every order; minimum order £400 + VAT. Delivered by Moffett lorry (forklift offload); someone must be present to receive it. We deliver to England and Wales only; we cannot deliver to Scotland, Northern Ireland or the islands.

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.
