SILEX Fiberglass Windows & Doors
This September, Award Magazine spotlighted Zhen Liu, the owner of SILEX, for his leadership in advancing curtain wall and window wall systems designed for the evolving needs of Canadian construction. The feature highlights how SILEX is driving innovation in facade design, performance, and sustainability, particularly for architects and building professionals seeking high-performance solutions that meet today’s most stringent codes.
“As energy codes evolve and buildings aim for higher performance, managing solar heat gain and facade thermal efficiency has become essential – especially on south- and west-facing elevations with extensive glazing,” says Zhen Liu of SILEX.
With stricter building energy codes in Canada, façade design has become a critical factor in meeting performance targets. While aluminum remains durable and widely used, its high thermal conductivity can increase energy loss.
SILEX’s fibreglass curtain wall and window wall systems directly address these challenges, offering advanced solutions to improve envelope performance and reduce energy consumption.
Excessive solar heat gain is often due to glazing choices, but as Liu notes, frame conductivity also plays a significant role. This is why Canadian-made fibreglass systems are gaining traction among architects and developers.
Superior thermal insulation: Significantly reduces conductivity compared to aluminum
Design flexibility: Supports modern, high-performance architecture without compromising structural strength
Lower embodied carbon: Supports sustainable construction practices and green building certifications
Shorter lead times & price stability: Locally sourced materials reduce delays and mitigate global price volatility
For projects targeting Passive House, Net Zero, or LEED certifications, fibreglass offers a proven path to compliance and performance.
Material selection is no longer just about durability, and it is also about meeting sustainability goals and reducing lifecycle costs. With aluminum prices rising and growing demand for local sourcing, SILEX’s fibreglass solutions offer:
Reliable supply chains with Canadian manufacturing
Compliance with evolving building codes
Clean, modern aesthetics for both curtain wall and window wall applications
As Liu notes, “SILEX fibreglass systems exemplify this shift, with low-conductivity profiles and clean lines making them a popular choice for Passive House, Net Zero, and other high-performance projects.”
