Kingspan K7 Pitched Roof Board

Kingspan Kooltherm K7 Pitched Roof Board has a fibre-free rigid thermoset phenolic core which is faced on both sides with a low emissivity composite foil, which is bonded to the insulation core during manufacture. K7 is designed for tiled or slated pitched warm roof spaces, effectively helping to prevent heat loss due to its excellent thermal conductivity of 0.020-0.023W/m2K. The insulation core itself is very durable, long-lasting and resistant to short-term contact with solvents, fungi and rodents.

Kingspan K7 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 insulation boards are easy to handle and install and are resistant to the passage of water vapour, keeping your roof space warm and dry.
