Thin-R Partial Fill Cavity Wall XT/CW (T&G) builds to a system thanks to its engineered tongue and groove joints and pre-formed corners, ensuring insulation continuity and minimisation of thermal bridging.
XT/CW (T&G) for use in traditional masonry walls, builds to the highest thermal standards whilst maintaining a residual cavity, offering protection from wind driven rain.
- Thermal Conductivity is 0.022 W/m²·k (BS EN 13165:2008)
- Thermal Resistance for this 100mm T&G is 4.50 W/m²·k

The Unilin (previously Xtratherm) Cavity Wall System includes an optional pre-formed corner panel (XT/CRN) that folds to 90 degrees to effectively insulate a corner junction that is normally vulnerable to thermal bridging and cold spots.
The XT/CW (T&G) tongue and groove jointing offer a practical on-site solution that results in a more robust continuous layer of insulation, minimising the threat of thermal bridging and improving the overall U-Value of the wall.
The low emissivity foil facing on XT/CW (T&G) improves the thermal performance of the wall.
The residual cavity is the most effective method of preventing wind-driven rain from penetrating a wall from the outside.
A residual cavity is the air space that remains when XT/CW (T&G) is placed against the inner leaf of the cavity of a wall.
The recommended residual cavity width required is 50mm in accordance with agrément certification, however, a reduced cavity may be permissible in certain circumstances.
Handling, Cutting and Storage
Xtratherm insulation should be stored off the ground, on a clean flat surface and must be stored undercover.
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.
Please refer to Health & Safety data sheets on the manufacturer website.
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.
