40mm Celotex TB4000 PIR Insulation Board (TB4040) is an easy to cut and install multi-purpose polyisocyanurate (PIR) rigid foam insulation board featuring a low emissivity foil facings that is suitable for floor, wall, ceiling and roof cut-to-fit applications.
Celotex Insulation Board is an excellent high-performance thermal insulation material with a thermal conductivity as low as 0.022 W/m.K which helps to reduce the thickness of insulation required to hit the target U-values.
TB4040 Celotex Insulation has been assessed by the BBA for its defined applications and compliance with the relevant Building Regulations.
PIR boards by Celotex enhance space in the construction design and help to reduce the heating and cooling costs within the building.
Celotex boards are versatile and available in a wide range of thicknesses from 12mm to 200mm (TB4000, GA4000 and XR4000).
TB4000 will help you to meet the requirements of UK thermal building regulations.
Celotex PIR rigid insulation boards can be readily cut using a sharp knife.

We can help to calculate price per m2 or linear meter (one meter in length) cost, please just contact us via phone 02081910776, email or live chat. 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.
4 TIPS FOR CHOOSING THE BEST INSULATION INSTALLER
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.
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.
