Kingspan Kooltherm

The preference for Kingspan Kooltherm is well deserved, as the material has a thermal conductivity of 0.019 W/m.K, offering some of the best wholesale prices for high-performance insulation. That makes Kingspan insulation one of the most thermally efficient insulation materials available to buy online.

It does not matter the application; you can be assured of reliability and quality if you choose Kingspan sheets. This makes it a favourite for trade and DIY customers across the UK.

What is Kingspan Kooltherm?

Kingspan Kooltherm is a phenolic board designed for walls, floors, and roofs. The Kingspan boards and sheets are manufactured very thin, minimising the depth required for insulation, and are supplied in project-ready stock. These boards give you more floor and loft space and ceiling height.

Because they do not contain fibre in their cores, they are easy and safe to install and can be supplied at volume discounts for large projects. Combine that with the low thermal conductivity, and we have a winner.

Kingspan Kooltherm Product Range

Kooltherm boards are made using a fibre-free thermoset phenolic core and exceptionally low thermal conductivity (approx. 0.019 W/m·K), making them outstanding for thermal applications in a compact package and easy to order as phenolic products online.

K103 – Floorboard

Designed to perform for both solid concrete and suspended timber floors. The rigid phenolic core and glass tissue facings make it perfect for buildings with underfloor heating installed.

K106 – Full-fill Cavity Board

This board is designed for full-fill cavity walls with residual cavities of about 10mm. It comes with a vapour-open polypropylene fleece facing that keeps out moisture, delivering high performance with a thin profile.

K107 – Pitched Roof Board

Ideal for pitched roof applications with a thin profile, low-emissivity foil facing. It works perfectly for tiled or slated roofs as well as loft conversions.

K108 – Partial-fill Cavity Board

This lightweight and easy-to-install board is ideal for partial-fill cavity walls. It has the same slender format as the rest of the series and is particularly favored for applications where the highest performance is critical.

K110 – Soffit Board

As the name implies, this is designed for soffits (thin structural ceilings). The PLUS version adds impact resistance, enhancing durability and finish.

K112 – Framing Board

For framing applications, this foil-faced board design ensures a tight fit and superior insulation in stud-and-frame applications.

K118 – Insulated Plasterboard

Combining dry lining, insulation, and vapor control, the K118 board is perfect for internal walls when external insulation isn’t feasible. It delivers efficient performance with minimal thickness.

K15 – Rainscreen Board

Designed specifically for rainscreen cladding systems. It offers a high insulation value behind a ventilated facade, especially where thickness is a key consideration.

K5 – External Wall Board

Made for external masonry walls and compatible with render systems, the K5 provides excellent thermal performance with a slim profile, making it ideal for retrofits. It is available with wholesale pricing options for large orders.

Thermoset And Fire Performance Characteristics

The fire performance characteristics of Kingspan Kooltherm are exceptional. Because it is a thermoset material, it hardens and chars when burned, producing minimal smoke. This is a favourable characteristic for users because the alternative involves thermoplastics like Polystyrene, which melt, become soft, and emit thick black smoke clouds when burned.
