56mm Unilin XO/STP Xtroliner Soffit Plus is an effective thermal and fire performance insulation solution used in structural ceiling applications in both commercial and residential buildings.

XO/STP Soffit Plus, comprising a rigid modified PIR core bonded to an impact-resistant 6mm building panel which offers a secure finish for ease of maintenance to which a decorative finish may be applied.

The bonded facing of the non-combustible building panel is water and impact resistant, providing a durable protection to which a decorative finish may be applied such as an acrylic based render.

Using XtroLiner Soffit Plus on soffit areas, whether new build or refurbishment situations, provides the most efficient U-Values with minimal thickness of insulation.

Unilin XO/STP achieves a thermal conductivity (lambda value) of 0.021 W/mK and has a Euroclass B s1 d0 fire classification.

XtroLiner Soffit Plus can be fixed directly to the concrete slab, onto battens or used with proprietary fixing systems, to provide an even surface.

The lightweight rigid product is convenient to handle and allows for fast and easy fixing.

XO/STP Unilin Xtroliner Soffit+ Insulation Board Installation Guidelines:

 · Fixing Directly to Concrete - Where applicable, ensure cavity wall insulation has continued past the soffit insulation to reduce Thermal Bridging.

 · Install XtroLiner Soffit Plus onto the soffit ensuring all joints are supported.

 · The boards should be tightly butt jointed, laid staggered in a break bonded pattern and fitted tightly at edges and around any service penetrations.

 · Any gaps or service penetrations should be addressed with propriety fillers and components in accordance with fire engineers specifications.

 · Fix XtroLiner Soffit Plus to soffit with approved fixings*, ensuring the fixings penetrate the substrate by a minimum of 40mm.

 · Generally, 12 fixings (min shank diameter of 5.2mm) per board are required.

 · Fixings should have a head diameter of at least 35mm.

 · Distribute fixings evenly across the board, at max 600mm across and 800mm along.

 · It is recommended to seek advice from the fixing manufacturer for specific guidance.

 · Boards joints can be covered with a suitable cover strip (acrylic tape).

 · Fixing to Timber Battens/Proprietary Systems - Treated timber battens may be used to provide an even surface when direct fixing to the soffit is not possible.

 · Battens should be treated timber.

 · The battens, measuring minimum 50mm x 40mm, should be mechanically fastened at minimum 600mm centres.

 · Fix XtroLiner Soffit Plus to the timber battens with approved fixings*, ensuring the fixings penetrate the substrate by a minimum of 40mm.

 · Ensure joints are tightly butted and fill any gaps with fire retardant expanding foam.

 · Generally 12 fixings (min shank diameter of 5.2mm) per board are required.

 · Fixings should have a head diameter of at least 35mm.

 · Distribute fixings evenly across the board, at max 600mm across and 800mm along, at a minimum of 50mm from the board edge and a maximum of 150mm.

 · Refer to fixing patterns below for indicative purposes.

 · It is recommended to seek advice from the fixing manufacturer for specific guidance.

 · When using proprietary metal grid systems, refer to the manufacturer for fixing instructions.

 · Board joints can be covered with a suitable cover strip (acrylic tape).

 · Fixing* type and specification should be verified by the fixing manufacturer's design, to take account of topographical and fire considerations.

 · Account should be taken of any Thermal Bridging through the fixings as should the effect of any supporting beams.

 · Recommended fixing manufacturers: Ejot or Fischer.
