Thin-R

XT/TL

Thin-R Thermal Liner (Dot & Dab) is a composite insulated panel of Unilin PIR insulation core with a composite kraft facing bonded to 12.5mm tapered edge plasterboard for internal applications, fixed with proprietary adhesive bonding.

The composite kraft facing on both sides incorporates an integral vapour control layer, which helps to reduce the risk of condensation. Thin-R Thermal Liners are designed to provide high levels of thermal insulation and drylining in one operation, providing the solution of choice in new build and renovation. Whether building new or upgrading, due consideration towards the energy efficiency of your home can have many benefits, including reduced energy costs and improved living conditions.

Specification Clause

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

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

Refer to NBS clause K10 205, K10 15, K10 245, K10 35, K10 155, K45 45. Uniclass 25 71 63 66.

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 kraft 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 continuous ribbons of adhesive and prevent fire penetrating behind the insulation layer. These continuous ribbons of adhesive also help to prevent thermal looping, leading to an overall improved U-Value for the wall element.
