Upgrade Your Building’s Efficiency with Kingspan PIR Insulation
Good insulation is one of the most effective upgrades you can make to a building, whether it is a new build, an extension or a renovation. Kingspan PIR (polyisocyanurate) boards give a high thermal resistance for their thickness, so you can reach your target U-value without losing more space than you need to. We stock a wide range of Kingspan boards at trade prices, delivered across England. Browse the full Kingspan insulation range.
Why choose Kingspan PIR insulation?
- Thermal performance: Kingspan Thermapitch TP10 declares a thermal conductivity of 0.022 W/mK, so a 100mm board has a thermal resistance of 4.50 m²K/W, according to Kingspan's datasheet.
- Foil-faced boards: TP10 has composite foil facings on both sides.
- Standard sheet size: TP10 comes in 2400 × 1200mm (8ft × 4ft) sheets covering 2.88m², easy to cut to fit between rafters, joists and studs.
- A board for each job: pitched roofs, floors, walls, cavities and flat roofs each have a dedicated Kingspan product.
Which Kingspan board do you need?
| Application | Kingspan board | Example |
|---|---|---|
| Pitched roofs, floors and walls | Thermapitch TP10 (PIR) | TP10 50mm (R 2.25), TP10 100mm (R 4.50) |
| Partial-fill cavity walls | Thermawall TW50 (PIR) | TW50 100mm (R 4.50) |
| Flat roofs | Thermaroof TR24, TR26, TR27 (PIR) | TR26 100mm |
| Tight spaces (phenolic) | Kooltherm K103, K106, K107, K108, K112, K118 | K106 90mm (R 4.70) |
R-values are in m²K/W, from Kingspan's datasheets as shown on each product page. Our guide to buying Kingspan insulation online goes through each board in more detail.
Installation
PIR boards are light and cut cleanly with a fine-toothed saw or a sharp knife. Cut boards to fit tightly, tape joints with foil tape where the design calls for it and follow Kingspan's installation guidance for your application. See how to cut PIR insulation board for tools and tips, and what thickness of PIR insulation you need for typical thicknesses.
Kingspan or Celotex?
We also stock Celotex (now Sopratherm) boards. Celotex GA4000 and Kingspan TP10 both declare 0.022 W/mK, so they give the same R-value at the same thickness. Read Kingspan TP10 vs Celotex XR4000 and our Celotex vs Kingspan vs Recticel comparison.
