In an effort to improve energy efficiency and reduce heating bills for their tenants, Albyn Housing Association appointed SIG Energy Management to undertake a scheme of refurbishment works, after surveying the properties it was established that the following improvements could be made to reduce the thermal leakage and carbon emissions for each property:

  • Replacement Loft Insulation
  • Installation of an externally fitted Air Source Heating Pump
  • Installation of External Wall Insulation (EWI)

As an approved installer of the Weber EWI System that was selected for the works, Skyform was awarded the contract to undertake this aspect of the works to 115nr properties on the site over a 20 week programme.

The works were undertaken in the following sequence:

  • Erection of Access Scaffolding
  • The existing roof level fascia, guttering and down pipes were removed and replaced
  • Polyester Powder Coated aluminium over sills were fitted to all existing windows
  • Polyester Powder Coated aluminium trims were fixed below the existing eaves as a means of protecting the installed EWI system from weather damage
  • A Polyester Powder Coated aluminium base tray was mechanically fixed to the perimeter of each property at the damp proof course level
  • 100mm thick expanded polystyrene insulation was secured to the existing building using hammer fixings designed for use on the “no fines” concrete construction
  • The insulation board was coated with cement based render which was reinforced with plastic mesh
  • Finally a coloured top coat was applied into which a decorative stone chip was cast

The works began in November 2012 and we completed by March 2013, as such the biggest challenge to timely completion of the installation 10,000sqm of EWI is the effects of winter weather, however Skyform completed the works on time and within budget to the great satisfaction of both Albyn Housing Association and SIG Energy Management.
