Thermally Broken Sliding Door Applications

Thermally broken aluminium doors are a great solution for buildings requiring high-levels of thermal insulation, without sacrificing durability and easy access.

Our Horton 2021+ Sliding Door System is a thermally efficient design, suitable for installation in education, healthcare, retail & commercial settings, where focus on climate change and a drive towards net zero is of growing importance. This fully compliant thermal commercial sliding door system is designed for high traffic footfall, and is available with both manual & electronic locking options.

The slimline profile of our Horton 2021+ operator, combined with the durable Kestrel thermal sections provide a robust entrance solution without compromising aesthetics.
