24.5mm Unilin XT/TL-MF (Mech Fix) is a foil backed insulated plasterboard made of 15mm Unilin PIR insulation core bonded to 9.5mm plasterboard used for internal walls, sloped roofs and ceilings.

The composite foil facing on Unilin XT/TL-MF Insulation and Drylining 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.

An important factor when dry lining 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

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

XT/TL-MF Insulated Plasterboard is designed to save money and time by reducing the heat loss from buildings.

This insulated plasterboard can be readily cut using a sharp knife or fine toothed saw.

Appropriate PPE should be worn when handling Unilin XT/TL-MF Insulated Plasterboard.

The thermal conductivity (lambda value) of PIR rigid insulation foam core is 0.022W/mK.

Unilin XT/TL-MF Foil Backed Insulated Plasterboard Installation Step by Step:

1. Ensure the wall is dry, clean and free of protrusions. 

Any existing wallpaper should be removed.

2. Fix metal frame system or timber battens to the wall in accordance with the manufacturer’s instructions. 

Sections should be placed around all wall edges and around openings and services.

3. Fix the metal frame system or vertical timber battens at a maximum of 600mm centers. 

(incorporating a vertical DPC behind timber battens). 

Ensure framing system or battens are wide enough to offer 20mm support to all four edges of the plasterboard. 

Pack battens if necessary to level the wall. 

Extra noggins may be required when the Unilin XT/TL-MF is unsupported by the battens.

4. Lift the Unilin XT/TL-MF into position using wedges on the floor. 

Insulation should be cut back to accommodate an adjoining panel at external corners. 

Joints should be tightly butted.

5. Fix Unilin XT/TL-MF to the frame at 300mm centres using appropriate fixings eg. drywall screws, at least 12mm in from the board edge. 

The fixings should penetrate at least 25mm into the timber batten.

Fixings should be thermally broken where possible. 

6. Seal and tape the joints of Unilin XT/TL-MF to ensure a continuous vapour control layer is created. 

Fill any gaps with foam filler.

7. Plaster skim to finish.

When upgrading existing properties, a professional should be engaged to assess the property for appropriate insulation treatments and effective detailing. 

Walls should be dry and decoration stripped back to the wall substrate. 

Appropriate ventilation strategies must be considered as part of the overall energy upgrade.
