FAQs

Are your Kingspan prices ex VAT?

Yes. All prices are ex-VAT trade prices. Thermapitch TP10 is priced per 2400 × 1200mm sheet; most other Kingspan boards are sold in full manufacturer packs, with the pack size shown on each product.

Should I choose Kooltherm phenolic or Kingspan PIR?

Kooltherm phenolic boards are thinner for the same U-value, which helps where headroom or rafter depth is tight. PIR boards such as Thermapitch TP10 are usually the cheaper option per square metre. Our K103 vs PIR guide compares the two.

Do you deliver Kingspan boards free?

Delivery is free to England on insulation orders over £400 ex VAT, which is also our minimum order. Delivery is by Moffett lorry with forklift offload.
