Kingspan K107 Kooltherm (9 Products)

Kingspan Kooltherm K107 Pitched Roof Board is a premium performance insulation used to insulate warm roof spaces in both ventilated or unventilated pitched roofs, under both tiles and slates. K107 insulation delivers unparalleled protection against heat loss with minimal thickness. With the lowest thermal conductivity value on the market (0.018 W/mK), K107 is one of the industry's highest-performing insulants. Unaffected by air infiltration, the boards are water-resistant and resist both moisture and water vapour.

Kingspan K107 Kooltherm Applications


Kingspan Kooltherm K107 Pitched Roof Boards are the perfect thermal solution for insulating warm roof spaces. Their reflective, low-emissivity surface improves the thermal resistance of unventilated cavities adjoining the board.


If you're looking to insulate your roof without needing to re-roof, K107 pitched roof insulation is just right for the job.


The boards can be used in the following applications:

  • Tiled or slated pitched roofs

  • Dwarf wall stud insulation

  • Attic floors

  • Dormer windows

  • Flat ceilings

Frequently Asked Kingspan K107 Questions

Frequently Asked Questions About Kingspan Kooltherm K107 Boards

What Is Phenolic Insulation?

Phenolic foam is comprised of phenolic resin, a blowing agent, and an acid catalyst. It is used to make a range of products, one of the most popular being insulation boards which are faced by elements such as a low emissivity composite foil.


It has over 90% closed-cell formation with a fine cell structure, making it extremely rigid and easy to handle. The rigid thermoset insulation core is protected by two facings, which act as another barrier against the elements. 

What is The Difference Between PIR and Phenolic Insulation? 

Both PIR and phenolic are rigid thermoset foams that function as insulating cores between two facings. The main difference between them is the materials and the manufacturing process.

Whilst PIR has good thermal insulating properties, phenolic excels in thermal performance, reaching lows of 0.018 W/mK compared to the 0.022 W/mK of PIR. Despite the many rigid thermoset insulation materials on the market, you will not find a lower thermal resistance figure than phenolic insulation. 

Both phenolic and PIR foam have combustible properties. However, they do deliver excellent protection against moisture and are ideal for areas with high rainfalls. Rot or fungi growth won't be an issue when you invest in phenolic insulation.
