50mm Xtratherm SW/RS Stone Wool Insulation Slab is a non-combustible euroclass A1 stonewool insulation slab with an improved acoustic performance used for ventilated rainscreen cladding systems in standard and high rise buildings.

The SW/RS range of stone wool insulation provides surety when the highest fire performance is required and resilience during the build process for the application of mechanically fixed substrates.

Xtratherm SW/RS Stone Wool Rainscreen Insulation is suitable for use in ventilated facade, soffit, rainscreen and framing applications and closed systems such as curtain walling.

Utilising StoneWool in new build and refurbishment projects contributes to reducing the lifetime production of harmful emissions from buildings, minimising heating and cooling demand.

Stonewool Rainscreen insulation has a certified thermal conductivity (lambda value) of 0.035 W/mK.

Xtratherm SW/RS should be installed in accordance with instructions issued by the facade engineer.

Rainscreen Cladding Slabs are available in standard 1200mm x 600mm size with square edge profile.

Xtratherm SW/RS Rainscreen Insulation is CFC and HCFC free and is manufactured using a blowing agent with a low GWP and zero ODP.

SW/RS Stonewool is manufactured from a natural and plentiful resource and is recyclable.

Stone Wool Slabs are lightweight and can be easily cut to any shape with a fine tooth saw or a sharp knife.

Ventilated Rainscreen Cladding Xtratherm SW/RS Installation

 · Xtratherm Stonewool is delivered in packs wrapped in polythene suitable for short term storage in the open.

 · For longer periods of storage packs should be stored off the ground and under cover.

 · The high density panels are robust enough to endure a reasonable length of time exposed during installation, however as with all building processes, protection during the build process should be provided where possible.

 · Breather membranes if specified within the system will provide additional protection.

 · Panels are lightweight and easily cut to any shape with a fine tooth saw or a sharp knife.

 · Neat fitting to adjoining boards and around any penetrations is essential to achieve good thermal performances.

 · Tight abutment with adjoining boards allows for continuity.

 · Boards should be applied in a break-bonded pattern.

 · With all joints tightly butted.

 · Using a combination of metal and polypropylene ‘mushroom’ type fixings with a minimum diameter of 70mm will provide adequate fix until the main cladding system is applied.

 · All penetrations, through the insulation layer, at floor junctions and openings should be accounted for in the thermal calculations.

 · For advice on rainscreen fixings, contact the system specifier, ensuring all fixings are accounted for when modelling thermal performance.

 · Suitable Board Fixing Manufacturers - Hilti, EJOT, Fischer, Rawlplug Fixings and W-M MLN Fixings.
