70mm K15 Kingspan Kooltherm Rainscreen Cladding Insulation (pack of 5) is a fiber–free rigid thermoset phenolic insulation board faced on both sides with a low emissivity composite foil facing.

Rainscreen Cladding Insulation K15 70mm provides the highest R–value per inch when compared to commonly available equivalent insulation products in the UK, allowing U-values to be met with minimal thickness.

Kooltherm K15 is commonly used as insulation for rainscreen cladding systems with non-proprietary external finish, rainscreen cladding systems with terracotta clay tile external finish and rainscreen cladding systems on steel frames.

K15 Rainscreen Cladding Façade Board 2400x1200x70mm is a lightweight insulation that is easy to transport, handle and install, and an ideal solution for new build and refurbishment projects.

Using K15 you can get thinner walls that can allow more natural daylight into your building with lowest reported ASTM E84 smoke developed index rating for foam insulations and minimal flame spread.

Rainscreen Board Kingspan Kooltherm K15 achieves Euroclass C-s2,d0 Reaction to Fire when classified to EN 13501-1: 2018.

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.
