52.5mm SR/TB-MR Moisture Resistant Insulated Plasterboard, comprising a 40mm thick rigid phenolic core bonded to 12.5mm moisture resistant plasterboard used for dry lining in high humidity conditions.

MR Insulated Drylining Board improves moisture resistance and thermal performance by reducing effects of moisture and heat loss in kitchens, bathrooms, toilets, walls, roofs and ceilings.

Foil facing on both sides of rigid foam Unilin phenolic insulation core incorporates an integral vapour control layer, which helps to reduce the risk of condensation.

Thanks to its low emissivity foil facings SR/TB-MR, facing into an unventilated air void between metal frame system/vertical timber battens, will improve the U-Value of the wall.

Safe-R SR/TB-MR Insulated dry lining wall insulation with certified lambda value (thermal conductivity) of 0.020 W/mK and Euroclass B-s1, d0 reaction to fire classification.

SR/TB-MR is moisture resistant thermal insulation board suitable for a wide range of dry lining applications in new build and refurbishment projects.

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.

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

Unilin SR/TB-MR (Moisture Resistant) Insulated Plasterboard Installation Guidelines:

 · Mechanically fixing procedure for moisture resistant insulated plasterboard applications.

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

 · Any existing wallpaper should be removed.

 · Fix the metal frame system/vertical 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.

 · Fix the metal frame system/vertical timber battens at a maximum of 600mm centres (incorporating a vertical DPC behind timber battens).

 · Ensure framing systems/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 SR/TB-MR is unsupported by the battens.

 · Lift the SR/TB-MR 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.

 · Fix SR/TB-MR 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.

 · Seal and tape the joints of SR/TB-MR to ensure a continuous vapour control layer is created.

 · Fill any gaps with foam filler and plaster skim to finish.

 · Note on other variations - 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.

 · Guidance in PAS2030:2019 ‘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.

 · ACDs must be followed to ensure that installation is in accordance with current Building Regulations and accounted for in the energy calculation.

 · Adhesive bonding (Dot and Dab) procedure for moisture resistant insulated plasterboard applications.

 · Ensure the wall is dry and free from any protrusions/wall paper etc.

 · Mark the position of Unilin SR/TB-MR Insulated Plasterboard on the wall.

 · Setting out and planning insulated board positioning is essential.

 · Apply adhesive dabs to the wall in accordance with BS8212, ensuring a 50mm continuous ribbon of adhesive is created at the top and bottom of each board and around all openings.

 · Follow adhesive manufacturer’s guidelines.

 · General recommendation is to apply vertical dabs at 300mm centres, 25mm in from the edge.

 · Dabs should be 50-75mm wide and approximately 25mm deep to allow for tamping.

 · Total contact with the board area should be a minimum 20%.

 · Maximum height installation for this system is 3m.

 · Lift the SR/TB-MR into position using wedges on the floor.

 · Apply pressure to the board to level and embed it into the adhesive.

 · Allow a 15mm expansion joint at the top and bottom of the panel, and fill with foam filler.

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

 · Joints should be tightly butted.

 · When the adhesive has dried, 3 mechanical fixings (thermally broken) should be fixed through the centre of the board.

 · Seal and tape the joints of SR/TB Insulated Plasterboard to ensure the continuous vapour control layer is created.

 · Plaster skim installed SR/TB-MR Insulated Plasterboards to finish.
