ah!60 – Performance

Inspired by Le Corbusier’s Five Points for a New Architecture, this collection offers boundless views through thermally broken external partitions. Like a screen, the sliding solution maximizes the openings in rooms to provide equal levels of lighting and selective views of the surrounding landscape.

With framing and a tracking system outfitted with Kawneer’s IsoPour Thermal Break barrier, these patio doors maintain interior climates to provide energy efficiency. The frame is designed to accommodate insulated glass for improved thermal performance. Meanwhile, the casters, tracks, and fasteners are made of corrosion-resistant stainless steel.

External Timber Doors

Accoya wood—sustainably harvested radiata pine that is acetylated to give it hardwood properties—is a durable material that works well in exterior timber frames. The wood is designed to prevent swelling and expansion for at least 50 years. Accoya wood can be used in front doors, bifolding doors, patio doors, and garage doors, among other applications.
