Obsidian frameless windows

Zero Waste Manufacturing

We manufacture glazing that reduces the carbon footprint of buildings throughout their entire lifespan. At the same time, we minimize waste and the energy consumption of our own production.

ESG in Obsidian glass

Responsibility in three dimensions

For us, ESG is not a marketing acronym. It is the way we approach production, people, and company management - every day, in every project.

Environment

Less waste, better buildings

We reduce material waste in production and deliver glazing that fundamentally reduces energy consumption in buildings throughout their entire lifespan.

Production waste under 15% (industry average: ~40%)

Obsidian frameless windows

Carbon footprint of buildings

Every window saves
energy for decades

The greatest ESG benefit of glazing is not just in manufacturing - it is in building operations. Quadruple glazing with a Uw of 0.3 W/m²K dramatically reduces energy consumption throughout the lifespan of the building.

Quadruple vs. triple glazing

Four-layer glazing with a Uw of 0.3 W/m²K, compared to standard triple glazing (Uw ~0.6-0.7), reduces heat loss through the window by more than 50%. With large-scale glazing, annual energy savings are in the range of thousands of kWh per building.

Solar factor and cooling

Special glass compositions reduce the solar factor, thereby lowering air conditioning demands in the summer months. Less cooling means lower electricity consumption and lower operational CO2 emissions — without compromising the brightness of the space. Properly designed glazing can reduce cooling energy consumption by 20-40% compared to standard windows.

Building life cycle

Obsidian glazing is designed for a lifespan of 30+ years. The lower energy consumption of the building translates into a reduction of overall CO₂ emissions over its entire lifetime - not just for the initial certification. LCA (Life Cycle Assessment) calculations are available for designers and architects upon request.

Passive and low-energy buildings

Obsidian quadruple glazing meets the parameters for passive houses (PHI standard). For corporate buildings with LEED or BREEAM certification, we provide all technical documentation for evaluating the energy efficiency of the building envelope. Compatibility with LEED, BREEAM, and SBToolCZ assessments.

Material circularity

Materials returned to circulation

Glass and aluminum are two of the most recyclable industrial raw materials. Their repeated use without any loss of properties forms the basis of the circular approach in the construction industry.

01

100% recyclable glass

Glass can be recycled repeatedly without any loss of quality. Production offcuts are sorted and handed over to the glass recycling chain.

Closed-loop aluminum

Schüco aluminum profiles are made from a high proportion of recycled material. At the end of the building's lifespan, the profiles are fully recyclable.
