Kingspan Kooltherm K5 external wall board is a premium phenolic insulation board for external wall insulation systems. The insulation boards have a rigid phenolic core, which offers excellent thermal capabilities, and is ideal for use with our thin coat renders to create a highly effective insulation system.
Part of the EWI Pro space-saving system, the Kingspan Kooltherm K5 insulation board is ideal for applications where space is at a premium, for example for narrow passageways between buildings and for under window sills that cannot be extended. Although more expensive than EPS, the Kooltherm K5 external wall boards offer a higher level of thermal performance and therefore are ideal for maximising on performance without sacrificing too much external space.
A further advantage of Kingspan K5 insulation is that it has high compressive strength and is therefore ideal for applications where there is a higher risk of mechanical impact. This is especially useful if your building/property has external walls that are close to public footpaths/roads.
Kingspan K5 insulation is made of high-quality phenolic foam. It’s CFC and HCFC free and has an ozone depletion potential of zero. Its environmental impact is therefore very low for a foam insulation material. The boards should be installed using the EWI-225 Premium Basecoat for maximum structural stability, and then finished with a decorative thin coat render such as EWI-075. The result is a superior external insulation system with excellent thermal comfort for end-users.
Kooltherm K5 insulation boards should be installed in accordance with the manufacturer’s installation guidelines – these should cover design and all aspects of the application of the insulation. The boards are initially fixed to the substrate (masonry or timber) using our Premium Basecoat and metal screw mechanical fixings.
After having been fixed to an external wall, the Kingspan K5 boards should be covered with an outer layer, either by the mortar basecoat or simply by a netting covering to protect from excessive heat, moisture and UV exposure. A protective render topcoat should then be applied. For further information, please download our full installation guide.
Shelf life: please see the manufacturer’s date of expiry. Keep in a dry place, in the original packaging. Avoid excess heat or UV light exposure.
