K107 Pitched Roof Insulation Board Kingspan Kooltherm 75mm is an advanced pitched roof insulation board with an excellent thermal performance and thermal conductivity of 0.019 W/mK.

Pitched Roof Insulation Boards are easy to cut and handle, ensuring an efficient installation process, and can be trimmed to size to suit rafter spacings.

Kingspan Kooltherm K107 Insulation Boards are an ideal solution for insulating your roof and can be simply retrofitted when converting an attic where re-roofing is not needed.

K107 Pitched Roof Phenolic Insulation Board has low emissivity foil facings on both sides that greatly reduces heat loss through the roof and helps save on energy costs.

Kingspan Kooltherm K107 is one of the thinnest commonly used insulation for pitched roofs, allowing U-values to be reached with minimal thickness.

This product is a perfect choice for new build and refurbishment projects to create a usable attic or loft space.

K107 Kingspan Kooltherm Pitched Roof Insulation is an improved and upgraded version of previously supplied Kingspan K7 Insulation Board, the main advantage of the K107 product range is improved thermal conductivity.

When comparing K7 vs K107, it means the lower the thermal conductivity, the better the insulating material.

Currently, there isn't any direct equivalent to K107 Insulation Board that performs as good as Kingspan Kooltherm product range.

No matter whether you choose a local installer or a national company, there’s a few tips to help you find the right installer for your home insulation improvements, such as asking for recommendations and making sure that they’re part of a certification scheme. This makes sure that they have the right skills and standards of workmanship to carry out the installation, and you can be sure that they know exactly what they are doing.


1. Thermal inspection picture in portfolio

It’s worth seeing a installer’s previous work. There’s no harm asking if you can see any properties nearby that they’ve installed insulation in. Best way would be to see Infrared Thermal Imaging Inspections. Thermal cameras spot small, but key changes in temperature in different areas of a house, identifying problematic areas that the human eye never could and some that a visual inspection could only hypothesize.

2. Reviews

Along with checking recommendations and previous work, finding reviews online can often be a great way to find out if they provide a good service or not. However, it’s best not to solely rely on reviews you may find or review websites, as there’s no controlling who writes them.

3. Compare prices

Comparing prices will also ensure companies can’t take advantage of you and give you a fair price. 

4. Word of Mouth

The best way to find a great insulation installer is through recommendations. Make sure you ask friends and family. They will most likely give you their honest opinion and can tell you from first hand experience.


Whether you require a wall, cladding, external wall, loft or floor insulation fitted, you can find and hire your local insulation installers from popular UK web pages. A simple internet search will return thousands of potential installers near your area.
