On April 15, Alumilex, a Canadian manufacturer of custom high-performance aluminium windows and doors, announced that its new ALX2090 fixed and operable window system has been recognised by the Passive House Institute (PHI). PHI, which is the leading authority on energy-efficient building standards, awarded the prestigious Passive House component certification to the firm.

Earning this certification showcases the firm to be highly dedicated towards enhancing the aluminium overall performance, as well as putting its ALX2090 series at the forefront in terms of the most demanding standards within the industry. With this series, the firm is able to expand the clear accessibility for the Canadian construction market by providing a wider range of certified high-performance components.

Benchmark to gain the certificate

In order to gain the Passive House certification, it is required to have a window system and it should hit a U-value (UW) of 0.80 W/(m²K) or lower. Alongside this, the window system would be required to meet hygiene standards for avoiding condensation risks (with an fRsi of 0.70 or above).

Looking at the firm's product series that just received the certification, it not only meets the requirements stated with a UW of 0.79 W/(m²K), but also boost a certified installed U-value (UW, installed) of 0.84 W/(m²K) when paired with exterior insulation systems. 

This enables energy efficiency because it makes use of an aluminium frame, which is thermally broken with polyamide (0.3 W/m•K), aerogel-filled cavities (0.016 W/m•K) and a 46.6mm triple-glazed unit, which is being complemented by a Swisspacer Ultimate warm-edge spacer.

By combining these features, the firm ensures airtightness, provides consistent thermal comfort and significantly cuts down on the building’s energy requirements. This is possible because the firm maintains the durability and design flexibility that aluminium offers.

Benefiting the Canadian market

By earning this certificate, the firm ensures that Canadian architects, contractors, and developers can choose a compliant, locally made product which is supported by the firm’s team in Montréal and Toronto.

Additionally, the certification that ALX2090 received includes three validated installation methods, which are the exterior insulation (EIFS/ITE), light wood frame and wood stud construction. This showcases that the Canadian market is now equipped with a variety of building assemblies for the Canadian residential and commercial projects.

Upholding sustainable construction in Canada

In terms of thermal performance, the firm’s ALX2090 not only saves energy but also lowers the carbon footprint throughout the building's lifespan, where the firm cuts down on heating and cooling energy needs.

As building codes across Canada become more rapid towards achieving net-zero-ready standards, holding certified high-performance fenestration components is now more crucial than optional. This puts the firm in a great position as a local supplier, fully equipped to tackle these changing demands.
