Thin-R

XT/TL-MF

Thin-R Thermal Liner (Mechanically Fixed) is a composite insulated panel of Unilin PIR insulation core with a composite foil facing bonded to 12.5mm tapered edge plasterboard for internal walls, sloped roofs and ceilings. It is only suitable for mechanically fixed applications.

The composite foil facing on both sides of this board incorporates an integral vapour control layer, which helps to reduce the risk of condensation. This Mechanically fixed Thermal Liner is designed to provide high levels of thermal insulation and drylining in one operation, providing the solution of choice in new build and renovation.

Benefits

Specification Clause

The insulated dry lining wall insulation shall be Thin-R XT/TL-MF manufactured to EN 13165 by Unilin Insulation, comprising a rigid Polyisocyanurate (PIR) core between low emissivity foil facings. The Thin-R XT/TL-MF _ _ mm with an Agrément declared Lambda value of 0.022 W/mK (PIR only) bonded to 12.5mm plasterboard to EN 13950, achieving a U-Value of _ _ _W/m2 K for the wall element. The insulated drylining plasterboard XT/TL-MF shall be mechanically fixed to battens, or proprietary system in accordance with instructions issued by Unilin Insulation.

An Environmental Product Declaration (EPD), certified by IGBC is available for this product. Please contact technical support for further details.

Refer to NBS clause K10 205, K10 15, K10 245.

Resistance ‘R’ Values

The resistance value of any thickness of material can be ascertained by dividing the thickness (in metres) by its lambda value, for example: Lambda 0.022 W/mK and PIR thickness 50mm -> 0.050/ 0.022 -> R-Value = 2.27. This is then added to the 12.5mm plasterboard resistance (0.066) to calculate the overall resistance of the composite board (2.27 + 0.066 ) = 2.336. In accordance with EN 13950, R-Values should be rounded down to the nearest 0.05 (m2 K/W).

Integral vapour control layer

The composite foil facing on this board provides a gas and vapour tight barrier, reducing the condensation risk. A continuous vapour control layer is created when the boards’ joints are sealed and taped in accordance with drylining good practice.

Fire Stops

An important factor when drylining a wall is to provide fire stops along the top and bottom of each board and around all openings (doors, windows, etc.). These are provided by the battens/studs and prevent fire penetrating behind the insulation layer. This also helps to prevent thermal looping, leading to an overall improved U-Value for the wall element.

Service Void

The void created between the battens/studs can be used for accommodating services.

Note: Improved Overall U-Value

Thanks to its low emissivity foil facings, this board facing into an unventilated air void between battens, will improve the U-Value of the wall.
