Unilin Thin-R Insulated Plasterboard 2400 x 1200 x 62.5mm

Thin-R Thermal Liner Dot & Dab XT/TL 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 of XT/TL incorporates an integral vapour control layer, which helps to reduce the risk of condensation. XT/TL is designed to provide high levels of thermal insulation and drylining in one operation, providing the solution of choice in newbuild 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.

Unilin Thin-R Range

Unilin Thin-R range is a high performance foil faced Polyisocyanurate (PIR) insulation with a certified thermal conductivity as Low as 0.022 W/mK. Thin-R is also available with engineered jointing to provide improved continuity and thermal bridging performance.

Key Benefits

• Insulation & Drylining in one Application.
• Provides Effective Vapour Control Layer.
• Reduced Insulation Thickness.
• Suitable for a Variety of Wall Types.
• Cost Effective Solution in Refurbishment and New Build.

Integral Vapour Control Layer

The composite kraft facing on XT/TL provides a gas and vapour-tight barrier, reducing the condensation risk. A continuous vapour control layer is created when the XT/TL 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.

Thermal Resistances

Property & Units

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 = 2.272. 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) = 2.338. In accordance with EN 13950, R-Values should be rounded down to the nearest 0.05 (m2K/W).

Durability

Unilin 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.

Handling, Cutting & Storage

Unilin 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.
