The aesthetic and material benefits of sustainable, well-engineered timber curtain walls are well documented. But Unicel Architectural’s Therm+ H-I curtain wall systems with proven RAICO technology and high-quality glazing by Unicel Architectural take curtain wall performance to the next level.

That’s because each Therm+ H-I curtain wall system (available in sizes of 56 and 76 mm) combines lightweight and elegant design with Passive House certification-level thermal insulation, along with superior wind resistance and greater air tightness than any other curtain wall product on the market.

Therm+ H-I curtain wall systems can be equipped with a range of glazing products, including double or triple glazed Vision Control™ integrated louvers for unprecedented comfort and control of vision, light, temperature and sound. Rich timber facades can be fabricated from any timber-based material, including glue laminated Douglas fir, red cedar, black spruce, or other woods – helping contribute to biophilic design principles.

The Therm+ H-I system strictly separates all structural elements from functional components, such as gaskets and the aluminum profile, for longer product life and functionality. Recent Unicel Architectural products featuring Therm+ H-I 56 and 76mm curtain walls include:

• The Osler Bluff Ski Club’s renovation project, featuring 450 sq. m. of curtain wall with red cedar solid wood caps, Douglas fir glulam, and double glazing
