20mm Kingspan Kooltherm K5 Wall Board is a high-performance masonry wall insulation board, with a fibre-free rigid thermoset phenolic core used for external wall insulation behind traditional, lightweight thin coat rendering and dry cladding systems.

Kooltherm K5 External Wall Board 20mm is a premium performance insulating material faced on both sides with mineral glass coatings bonded to the insulation core during the manufacturing process and thermal conductivity (lambda) of 0.022W/mK.

The core of Kingspan Kooltherm K5 Board is a highly efficient thermal phenolic insulation manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

The external wall insulation (EWI) system made using Kingspan K5 boards are durable and maintain its functional properties throughout the entire life of the building providing Euroclass C-s2,d0 fire rating.

Kingspan Kooltherm K5 Board for external wall insulation is compliant with Building Regulations and comes in handy to reduce insulation thickness while delivering outstanding thermal performance.

Using Kooltherm Kingspan K5 a higher insulation value is achieved with a thinner board thickness than with other insulation materials (such as EPS, XPS and mineral wool).

Kingspan K5 external wall insulation board is an easy to handle and install 1200mm x 600mm panel.

K5 is not cheap, but it is worth using because better insulation material means lower heating bills.

Gluing Kingspan Kooltherm K5:

We recommend Ceresit CT87 White Flexible Adhesive or Ceresit CT84 Express PU Foam Adhesive.

Experience shows that if we buy a really good insulation adhesive, it will work!

It is worth recalling that each panel should be glued with the circumferential-point method. 

After applying the glue, it should be on at least 40% of the board surface.
