The Kingspan Kooltherm range is an extensive range of high performance rigid thermoset phenolic insulation for roofs, walls and floors.

Kingspan Kooltherm offers among the most thermally efficient conductivity and thermal performance values available, which means you can minimise the thickness of your insulation compared to other conventional insulation to achieve the same performance.

Kingspan Kooltherm also has exceptional fire performance characteristics. As it is a thermoset material, it hardens and chars in fire situations, giving off very little smoke; unlike thermoplastics, such as polystyrene which melt, soften, and give off thick black smoke.

Phenolic insulation, like our Kooltherm range of products, is the most thermally efficient insulation commonly used. It is made through a manufacturing process where a rigid thermoset foam forms an insulating core between two facing elements, for example, a low emissivity composite foil.

Choosing a phenolic insulation will make it easier to reach those high target R-values with a minimal thickness of insulation.

Our Kooltherm and Therma ranges are closed-cell types of insulation. This type of insulation is resilient to the occasional light sprinkle of water but should always be kept and stored in dry conditions to maximise its thermal performance.

In cases where insulation is expected to get wet or where it is to be installed outside any tanking membrane, we recommend using Kingspan GreenGuard, which isn’t negatively affected by groundwater or moisture.

The masonry standard AS 3700 states “in cavity walls and masonry veneer walls, cavities with a minimum width of 40mm, which are properly detailed and constructed, shall be regarded as being resistant to the passage of moisture”.
Kingspan recommends a maintained 40 mm cavity in all cavity walls to reduce the risk of moisture penetration that can lead to structural damage, poor thermal performance, and health hazards.

Kooltherm is a range of advanced phenolic insulation. It is the thinnest commonly used insulation board for any specific R-value. This means that you can benefit from reduced heating or cooling demand or use thinner boards to gain more space in your building.

Therma is a range of PIR insulation boards.
