EWI onto Timber / Steel Framework

commercial-building.jpgTo meet NHBC requirements the JUB cavity rail system allows for a minimum 15mm drained cavity to be installed. The meets the requirements set out by NHBC and others for timber or steel framed structures. The cavity allows for any trapped moisture to drain out through the slotted base rail.

It is based on using either EPS or Mineral insulating panels that are flame retardant and available in a range of thicknesses to achieve the required level of thermal performance.

Whatever the substrate, External wall insulation can be used to to thermally upgrade and reduce the cost of heating. New life and longevity can be applied to existing buildings, whilst new-build benefits from a quicker more cost effective approach, rather than the traditional build of the past.

The JUB EWI System offers a number of key advantages:

  • U Values as low as 0.08 W/m2k
  • No internal disruption
  • Protects the building
  • Prolongs the lifetime of the building
  • Improves living conditions
  • Speed of application
  • Water repellant
  • Reduces CO2 emissions


Durable and Breathable the Jubizol Facade range combines the latest technology to provide a system that will repel dirt for longer, whilst allowing good vapour diffusion for a healthier living climate.
