Swisrail External Wall Insulation

Swisrail is a thin coat insulated render system specifically designed for use on framed buildings subject to NHBC approval. Swisrail incorporates a system of steel rails and channels to provide a 25mm drained cavity between the insulation and the steel frame to comply with NHBC guidelines. Swisrail is faced with Alumasc’s range of Silicone or Mineral renders which can be applied with rolled or dragged surface texture, in a wide range of colours.

The Swisrail external wall insulation system, with EPS insulation and lightweight Silicone render finish achieved an NHBC approved façade solution at the Osborne Apartments, Swansea. More...

Applications New Build – NHBC compliant, tailored to lightweight frame construction Construction Types – Primarily suited to new-build construction types A flexible ventilated system suitable for curved and complex detailed applications Buildings up to 6 Storeys – suited for unrestricted use High Rise applications - suitable subject to Alumasc’s high rise policy

Performance Fully warranted system with life expectancy in excess of 30 years Incorporates air gap via a support frame to give full NHBC compliance. System provides a cavity to allow airflow and draining to the underlying structure Fully weather resistant whilst remaining vapour permeable Allows the fabric of the building to act as a heat store, increasing thermal efficiency Eliminates cold bridging, condensation and mould growth Protects structural fabric, limiting movement and thermal shock and freeze-thaw cycles associated with traditional brickwork façades Highly resistant to impact damage Rated Class 0 for surface spread of flame Contributes to sound reduction within external wall construction

Insulation & Finishes Choice of insulation thicknesses and materials, achieving very low U-values Vertical steel support rails provide a 25mm gap between insulation and structure Lightweight, through-coloured render finishes include ST Silicone and Mineral Eco-friendly option consisting Mineral Wool or Cork insulation with Mineral render

Installation & Maintenance Installed by approved specialist contractors Requires minimal routine maintenance
