What Sustainability Really Means in Architectural Glazing: DOVISTA’s Approach Explained
Sustainability gets talked about a lot in the glazing industry — but not always with much substance behind it. Carbon reduction claims, “eco” labels and green credentials are everywhere. Yet it can be difficult to understand what actually makes a difference when specifying windows and doors.
At Westcott Architectural Glazing, we work closely with manufacturers whose sustainability commitments go beyond marketing. One of the most significant of these is DOVISTA — a European window and door group that has embedded sustainability into how its products are designed, manufactured and measured.
In this article, we look at what DOVISTA’s approach to sustainability really involves, why it matters for architectural glazing, and how it translates into meaningful benefits for the projects we deliver.
Who Is DOVISTA, and Why Their Role Matters
DOVISTA is one of Europe’s largest window and door groups, employing thousands of people across multiple countries and manufacturing a wide range of timber, aluminium, composite and PVC systems. Brands within the group include VELFAC, Rationel, KRONE and others widely specified in architectural and design-led projects.
What makes DOVISTA particularly relevant is scale. Sustainability improvements made at this level don’t just affect one product line — they influence supply chains, material sourcing and manufacturing practices across the industry.
Their stated aim is simple: to bring daylight and fresh air into people’s homes, while reducing the environmental impact of doing so. The challenge, of course, lies in how that ambition is delivered in practice.
Sustainability as Strategy, Not a Side Project
One of the key differences with DOVISTA is that sustainability in glazing isn’t treated as an add-on. It sits at the centre of their long-term business strategy, with clear targets, reporting frameworks and accountability at board level.
Rather than vague commitments, DOVISTA has aligned its carbon reduction plans with internationally recognised science-based targets. Using 2021 as a baseline, the group has committed to significant reductions in emissions across its own operations and its wider value chain, with interim goals set for 2030 and a long-term objective of deep decarbonisation by 2050.
This matters because glazing is inherently energy- and material-intensive. Aluminium, glass and timber all carry embodied carbon, and meaningful progress depends on reducing impact at source — not just offsetting it later.
Measuring What Goes Into a Window or Door
A growing number of our architectural clients are asking a simple but important question: what is the environmental cost of this product before it’s even installed?
DOVISTA has responded to this by producing Environmental Product Declarations (EPDs) for many of its systems. These independently verified documents provide transparent data on embodied carbon, material composition and lifecycle impact.
For architects and developers working towards sustainability targets, EPDs allow informed comparisons between systems — not just on appearance and performance, but on environmental impact too. For homeowners, they provide reassurance that sustainability claims are grounded in measurable data rather than marketing language.
Circular Thinking in Glazing Manufacturing
One of the more interesting aspects of DOVISTA’s sustainability work is its focus on circular innovation — particularly around glass.
Traditionally, insulated glass units that don’t meet final quality standards are discarded, even though much of the material remains perfectly usable. Through partnerships with organisations such as VELUX and again, DOVISTA is helping to develop processes. These allow rejected glass units to be repurposed and reintroduced into new products.
This approach reduces waste, lowers the demand for virgin materials and preserves the embedded value already invested in manufacturing the glass. It’s a practical example of circular economy principles being applied to real-world production, rather than remaining a theoretical goal.
Why This Matters for Glazing Projects in the UK
For clients specifying windows and doors today, sustainability is no longer just about operational energy efficiency. Embodied carbon, material sourcing and long-term durability all play an increasingly important role.
DOVISTA’s approach supports this shift. Lower-carbon aluminium options, transparent environmental data and long-term supply chain stability all help reduce risk and support compliance with evolving planning and regulatory expectations.
For larger projects, this can contribute to broader sustainability frameworks such as BREEAM or LEED. For private homes, it simply means investing in products designed to last — both physically and environmentally.
How Westcott Architectural Glazing Applies These Principles
At Westcott Architectural Glazing, sustainability isn’t something we treat in isolation from performance or design. The products we specify must meet architectural intent, deliver long-term reliability, and align with the environmental expectations of modern construction.
Working with DOVISTA allows us to do that with confidence. We can draw on verified environmental data when advising clients and support architects with specification details. We also offer glazing systems that balance slim profiles, thermal performance and reduced environmental impact.
Just as importantly, we’re honest about where sustainability claims begin and end. Not every project requires the same approach, and not every solution fits every brief. Our role is to help clients make informed choices — not to overstate what glazing alone can achieve.
A More Practical Way to Think About Sustainability in Architectural Glazing
True sustainability in glazing isn’t about chasing labels or trends. It’s about reducing waste, using materials responsibly, and designing systems that perform well over decades rather than years.
DOVISTA’s work shows what’s possible when sustainability is treated as a long-term commitment rather than a marketing exercise. By partnering with manufacturers who take that approach seriously, Westcott Architectural Glazing is able to deliver projects that look exceptional, perform reliably, and move the industry in the right direction.
