SolarWall® Systems by Conserval is the global market leader in solar air heating for buildings. Founder John Hollick invented the transpired solar collector, branded as “SolarWall heating”, more than 30 years ago. The company has designed and manufactured thousands of SolarWall® air heating systems worldwide for commercial and industrial buildings. There are over 5 million square feet of SolarWall air heating systems on 6 continents across the globe, from Alaska to the South Pole. These systems are helping businesses and municipalities achieve their energy goals and reduce their carbon footprint.
The SolarWall® technology is very architecturally versatile and can be styled, shaped, and designed in a variety of colours and profiles to augment the building envelope & generate on-site energy. It has been applied alongside a variety of building facades systems from masonry and concrete to insulated metal panels, Exterior Insulation and Finish Systems (EIFS) and other metal cladding. SolarWall systems have been used on architectural projects around the world with a consistent track record of successful results and eye-catching designs. Some are seamlessly integrated into the building envelope and others are curved or angled to achieve a desired appearance.
The SolarWall technology is favoured by building owners, architects, and engineers who want to use solar air heating because of its applicability to various green building standards and renewable energy targets. The end result is a portfolio of award-winning Net-Zero, Zero Carbon & LEED® certified buildings where the SolarWall system was a vital component of the project’s success.
