70mm Kingspan Kooltherm K103 Floorboard premium performance rigid phenolic insulation sheets

The perfect choice for new build and refurbishment projects when a high specification of insulation is required for solid concrete and suspended ground floors. Replacing the previous K3 version, these boards now have a lower lambda value which means the same thickness of insulation is now more thermally efficient than its predecessor

Only available in full packs consisting of 4 sheets 2400 x 1200 x 70mm which have a total coverage of 11.52m2.

Benefits of using Rigid Phenolic K103 Insulation

  • Premium performance rigid 70mm phenolic insulation–
    thermal conductivity as low as 0.019 W/m.K
  • Resists moisture penetration
  • Can reduce the cost of related items – soil removal, service connections
  • Non deleterious material
  • Unaffected by air infiltration
  • Easy to cut and handle

Environmentally friendly:

70mm Kooltherm K103 is manufactured with a blowing agent that has zero ozone depletion potential (ODP) and low global warming potential (GWP). This makes it a more sustainable choice than some other types of insulation.

Kooltherm K103 70mm is suitable for a wide range of floor applications, including:

Solid concrete floors: Kingspan Kooltherm K103 can be laid directly onto a prepared concrete subfloor, before being covered with a screed or other floor finish.
Suspended timber floors: Kooltherm K103 can be laid between the joists of a suspended timber floor, before being covered with floorboards or other floor finish.
Beam and block floors: Kingspan K103 can be laid between the beams of a beam and block floor, before being covered with a screed or other floor finish.
Underfloor heating: Kooltherm K103 Floorboard can be used as an insulation layer beneath underfloor heating systems.

Overall, K103 Floorboard offers a superior thermal performance when compared with other insulation materials.

Here are some additional benefits of using 70mm Kingspan Kooltherm K103:

Improved indoor air quality: Kooltherm K103 is a non-deleterious material, which means that it does not release any harmful chemicals or toxins into the air. This can help to improve indoor air quality and create a healthier environment for occupants.

Increased property value: A well-insulated property is more energy-efficient and comfortable to live in, which can make it more attractive to potential buyers and increase its value.

If you are looking for a high-performance insulation solution for your floor, Kingspan Kooltherm K103 is an excellent option to consider.
