24.5mm Xtratherm Thin-R XT/TL-MF Thermal Liner Mech Fix is an insulated panel combined of PIR rigid insulation foam core bonded to 9.5mm plasterboard suitable for internal masonry walls, sloped rafters and ceilings.

Xtratherm XT/TL-MF Mechanically Fixed Drylining Board is a highly versatile and durable thermal insulated plasterboard designed to save money and time by reducing the heat loss from buildings in roof, wall and ceiling applications.

The composite foil facings on both sides of the XT/TL-MF thermal laminate dry lining board incorporates an integral vapour control layer, which helps to reduce the risk of condensation and improve thermal performance.

Xtratherm Thin-r XT/TL-MF Thermal Liner Mech Fix improves energy efficiency of your home and has many benefits, including reduced energy costs and improved living conditions in both newbuild and refurbishment projects.

XT/TL-MF Mechanically Fixed Board is chemically inert and safe to use manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

Insulated Plasterboard Thin-R XT/TL-MF must be installed in accordance with guidance issued by Xtratherm.

XT/TL-MF Thin-R Xtratherm Thermaliner Drywall Boards are chemically inert and safe to use.

Lightweight and easy to install Thermal Liner XT/TL-MF Drylining Boards are straightforward to handle, fit and transport.

Thermal conductivity of PIR foam core is 0.022W/mK.

Thermal conductivity of plasterboard is 0.17W/mK.

Key points:

 · Insulation and drylining in one easy applicable product.

 · Provides effective Vapour Control Layer (VCL).

 · Thermal conductivity of PIR core as low as 0.022W/mK.

 · Reduced insulation thickness.

 · Helps to reduce the risk of condensation.

 · Suitable for a variety of wall types.

 · Cost effective 3 in 1 solution. 

 · Suitable for refurbishment and new build.

 · Improving living conditions.

 · Easy to install and decorate.

Handling, Cutting and Storage:

 · Xtratherm 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.

Durability:

 · Xtratherm 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.

Installation guideline 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 XT/TL-MF is unsupported by the battens.

4. Lift the 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 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 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.

Certification:

Guidance in PAS2030:2017 ‘Specification for the installation of energy efficiency measures.

(EEM) in existing buildings and BS8212 Code of practice for dry lining and partitions should be consulted.
