TENTAL - Sloped Glazing

Key Features

With TENTAL, not only you can imagine the world you want, you can build it too.

Developed to inspire architectural innovation, the TENTAL sloped glazing system offers design flexibility for inclined facades and glazed roofs. It accommodates glazing thicknesses from 6mm to 62mm and supports inclinations as shallow as 10° from horizontal.

With 50 or 60mm sightlines and a mullion-transom assembly, our sloped glazing option delivers seamless integration, maximising light and spatial openness while maintaining a clean, elegant aesthetic.

Engineered for versatility and performance, it supports circular design through responsible material use, easy disassembly, and high recycled content. Integrated roof windows enhance natural ventilation and energy efficiency.

Achieve bold, sustainable architecture with a system that balances form, function, and long-term value.

Versatile Design

This TENTAL sloped option accommodates glazing down to 10° from the horizontal, offering architects and specifiers greater flexibility when designing inclined facades or glazed roof structures. Available in 50 and 60mm profiles, it delivers robust structural performance, while a range of aluminium cover caps enhance the external aesthetic, ensuring a clean, modern look that meets the demands of contemporary commercial architecture.

Reliable Quality

The durable mullion-transom structure delivers long-term structural stability for sloped glazing. Capable of accommodating glazing thicknesses from 6mm to 62mm secured using pressure plates or targeted fixings, it enhances overall system performance, supporting superior weather resistance, thermal insulation, and energy efficiency for commercial building envelopes.

Ventilation and Comfort

Integrated top-hung roof windows support natural ventilation while doubling as Natural Smoke and Heat Exhaust Ventilators (NSHEVs), contributing to healthier indoor air quality and improved safety compliance. Available in sizes up to 2.5m x 1.2m and a maximum weight of 160kg, they combine design flexibility with high-performance functionality for modern commercial environments.

Carbon-Conscious Solution

TENTAL is made with at least 75% recycled content and is 95% recyclable, reducing its environmental impact. Made with Hydro CIRCAL® 75R (at least 75% recycled, end-of-life aluminium) as standard, the CO²e footprint of 1.9 kg CO² eq / kg Al. is around 80% lower than the European average emissions for primary aluminium production.
