Features and Benefits

Fire Protection: The Unilin XT/TL-FR delivers 30 minutes of fire protection via its distinctive pink paper face, making it an excellent choice for kitchens, bathrooms, toilets, walls, and ceiling insulation. Double-layer installation can achieve up to 60 minutes of fire resistance, offering superior safety performance in high-risk environments.

Thermal Performance: Featuring a PIR foam core with thermal conductivity of 0.022 W/mK and a fire-protective plasterboard layer rated at 0.24 W/mK, this board maximises thermal efficiency across your building envelope.

Vapour Control: An integral composite kraft facing on both sides incorporates a built-in vapour barrier, effectively minimising condensation risk and delivering long-lasting insulation performance.

Versatility: This drylining board suits numerous wall configurations in both new construction and refurbishment projects, accepting either plaster finishes or direct decoration for maximum design flexibility.

Ease of Installation: The Unilin XT/TL-FR insulated plasterboard cuts easily with a sharp knife or fine-toothed saw. Always wear appropriate personal protective equipment (PPE) when handling.

Note: For applications requiring a 60-minute fire rating, apply an additional layer of fire plasterboard over the Unilin XT/TL-FR insulated plasterboard.
