110mm Unilin XT/PR Thin-R is a PIR pitched roof insulation board with rigid foam core sandwiched between aluminium foil facings used for under rafter or between and over joist applications.

XT/PR is a high performance foil faced insulation foam board with a certified thermal conductivity of 0.022W/mK which helps to reduce thermal stress and condensation risk.

Roof construction is a fast, systematic method that results in high performing buildings with regard to energy efficiency in environmental terms.

Unilin’s Roofing Systems XT/PR bring roof insulation performance to new levels, surpassing the default values asked for in current building regulations.

Building Regulations now concentrate on ‘Whole House Performance’, when using Unilin XT/PR will improve the efficiency of the building fabric, delivering excellent U-Values.

Good detailing and attention to air tightness will also contribute to highly efficient constructions.

The low emissivity foil facing on Unilin XT/PR board improves the thermal performance of the roof.

Unilin XT/PR can help you achieve U-Values as low as 0.14 W/m2K within a roof construction.

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.
