Sustainable Aluminium Windows


At TECHNAL, you will find the window system that is most suitable for your project needs – from commercial to residential with many options in terms of design, performance and hardware options. Each system features a variety of safety and security options, achieves outstanding weather performance and a range of openings, inward and outward opening, casements, tilt before turn, reversible and sliding windows are all available, no matter what your project needs.

Aluminium has characteristics that make it an environmentally friendly material – it can be recycled over and over without losing any of its inherent strength, flexibility and lightness, and, recycling aluminium uses just 5% energy when compared to production of primary metal.

TECHNAL aluminium building systems are also extruded using two sustainable and eco-friendly aluminium alloys – Hydro CIRCAL® 75R and Hydro REDUXA® ensuring that sustainability assessment requirements such as LEED and BREAAM are considered right at the planning stages of projects.
