45mm Xtratherm XT/CW Partial Fill Cavity Wall is a high-quality, BBA certified, tongue and groove PIR insulation board with certified thermal conductivity of 0.022 W/mK designed for use in traditional masonry partial fill cavity walls.
Xtratherm Cavity Wall is a highly-durable, rot proof insulation board and will remain effective for the life span of the building.
XT/CW is a lightweight, easy to handle and install material which can be readily cut by bricklayer using a sharp knife.
Thin-R XT/CW offering highest thermal standards whilst maintaining a residual cavity - protection from wind driven rain.
Xtratherm Partial Fill Cavity Walls XT/CW (T&G) range is a top-class polyisocyanurate (PIR) insulation with composite foil facings and certified thermal conductivity as low as 0.022 W/mK.
High-efficiency foil faced polyisocyanurate (PIR) rigid foam insulation is commonly used in construction industry.
This product is an improvement of previously used PUR boards (polyurethane), typically produced as a foam and used as rigid thermal insulation.
XT/CW insulation core and composite foil facings resist attack by mould, fungi, bacteria and microbial growth.
PIR foam is not only safe but also beneficial to the health of building users and installers.

Handling, Cutting and Storage
Xtratherm insulation should be stored off the ground, on a clean flat surface and must be stored under cover.
The polythene wrapping is not considered adequate protection for outside exposure.
Care should be taken to protect the insulation in storage and during the build process.
The insulation boards can be readily cut using a sharp knife or fine toothed saw.
Ensure tight fitting of the insulation boards to achieve continuity of insulation as asked for within the ACDs.
Appropriate PPE should be worn when handling insulation.
The boards are wrapped in polythene packs and each pack is labelled with details of grade/type, size and number of pieces per pack.
Durability
Xtratherm products are stable, rot proof and will remain effective for the life span of the building, dependent on specification and installation.
Care should be taken to avoid contact with acids, petrol, alkalis and mineral oil, when contact is made, clean materials in a safe manner before installation.

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.
INSTALLERS
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.
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.
