Solar metal walls

Metal Solar Air Walls

Over the last 25 years, thousands of metal solar air walls have been designed and installed in Canada and abroad. They preheat fuel-fired systems and provide substantial renewable heat and cost savings.

Trigo is manufacturer of the Calento wall and is exclusive distributor of the Inspire wall from Atas International in Eastern Canada For architects, engineers and building professionals, Trigo answers all needs for all solar air metal applications:

  • Full range of colours and profiles
  • Certified transpired walls in aluminium and steel
  • Design and supply of the wall’s sub-structure
  • Integration and control strategy for HVAC system
  • Production of stamped shop drawings
  • Support on site and commissioning report
  • Monitoring and Energy reports

  • The most common way to design a solar metal wall is to position it upstream from a gas-fired make-up air unit. When solar radiation is available, the solar metal wall rises the air temperature by about 10°C to 25°C above ambient and thereby generates gas and energy savings.

  • A stand-alone system, with supply temperature control done via recirculation damper, may be the most suitable solution when make-up air units are far off the walls or the building is under negative pressure.

Inspire solar air heating panels from Atas, made of aluminium or zinc, are perforated with embossed slits instead of drilled holes, which prevents any removal of absorbing material. This is one of the reasons why Atas panels are the most efficient metal collectors.
