Description

URSA WALLTEC REFLEX is a lightweight, non-combustible, semi-rigid glass mineral wool slab treated with silicon based water repellent. The slabs are faced with a microperforated aluminium foil on one side. URSA WALLTEC REFLEX has a thermal conductivity of 0.032 W/mK.


Features and benefits:

  • Labour and cost saving - Larger slab size means 12.5% fewer boards to install and 12.5% fewer fixings required.
  • Fire performance - A fire rating of Euroclass A1 makes them totally non-combustible and fire safe.
  • Environment - Ursa mineral wool is manufactured from an abundant, sustainable resource and utilises up to 73% glass waste.
  • Global warming potential - Does not use chemical blowing agents so the Global Warming Potential (GWP) arising from them is zero.
  • User friendly - Ursa Terra mineral wool has a ‘soft touch’ feel making it easier to handle and install while maintaining its mechanical properties.
  • Acoustic - The sound insulation characteristics help to enhance the acoustic comfort of the building.
  • UKCA/CE marked.
