120mm Kingspan Thermaroof TR24 Flat Roof Board (600mm x 1200mm) is an insulation sheet compatible with the majority of torch on applied waterproofing systems, an ideal solution for both new build and refurbishment projects.

The core of Kingspan Thermaroof® TR24 is manufactured with Nilflam® technology, an advanced insulant manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

The upper facing of Thermaroof TR24 Kingspan is bitumen coated glass tissue finished with a thermofusible polypropylene fleece, autohesively bonded to the insulation core during manufacture. 

The lower facing of Kingspan Thermaroof TR24 is a mineralised glass tissue autohesively bonded to the insulation core during the manufacturing process.

120mm x 600mm x 1200mm Kingspan Thermaroof TR24 Flat Roof Insulation Boards achieve a thermal conductivity (lambda-value) of 0.024 W/mK.

Thermaroof TR24 compressive strength typically exceeds 150 kPa at 10% compression to maintain its structural integrity when compressed.

The higher the compressive strength the better the material is at maintaining its structural integrity.

Kingspan Thermaroof TR24 achieves a resistivity greater than 300 MNs/gm, when tested in accordance with BS EN 12086: 2013.

Flat Roof Insulation Board TR24 should always be installed over a vapour control layer or sealed metal deck.

If correctly installed, Kingspan Thermaroof® TR24 can have an indefinite life.

Its durability depends on the supporting structure and the conditions of its use.

Alternatively, you can work it out yourself quickly and easily: to get cost per meter square please divide price shown in orange area by ''Required area (m2)'' Example price of £28.80 divided by board coverage 2.88m2 = cost of £10.00 per m2.


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.
