Ash Pearson, sales manager at Jack Aluminium Systems, shares his view on how aluminium glazing is evolving, and why demonstrated performance is becoming the industry benchmark.

If there’s one clear shift in the glazing market as we move through 2026, it’s this: performance claims aren’t enough anymore. The industry is asking for proof.

Specifications have always referenced standards and test results, but today there is far greater emphasis on how systems perform in reality, at real sizes, in real configurations and under real conditions. That shift is influencing how systems are developed, tested and ultimately specified.

We’re seeing it day to day. Conversations now go beyond aesthetics and baseline compliance. They’re about verified performance, tested configurations and confidence that systems will perform in real buildings, not just on paper.

Real buildings, real sizes
Across both commercial and residential projects, buildings are changing. Entrances are larger, glazing spans are wider and expectations around longevity are higher. High-traffic use is no longer limited to commercial spaces; residential developments are also seeing more communal entrances, shared lobbies and multi-occupancy demands.

All of this puts greater focus on how closely test evidence reflects what is actually being installed.

Testing at realistic sizes and configurations is becoming more relevant to everyone involved in a project. A system tested at scale gives a clearer indication of how it will perform in everyday use.

Recent PAS 24 testing on our SD70 heritage-style door at 2.1m x 2.5m is a good example. Those are not niche dimensions – they reflect what fabricators are regularly being asked to deliver. Testing at that scale provides reassurance that performance translates beyond the test rig.

The same thinking applies in security-led environments. Our TD68 thermal commercial door system achieving STS202 BR2 offers a tested aluminium option for higher-risk entrances where steel has traditionally been specified. In schools, healthcare and civic buildings, the balance between security, thermal efficiency and usability is increasingly important.

Residential is part of the performance conversation
Performance expectations are rising in residential too. Homeowners and developers are more informed about energy efficiency, durability and long-term value. That naturally feeds into specification choices.

Heritage designs remain popular, but clients also expect modern performance behind traditional sightlines. That’s driving demand for systems that combine slim profiles with credible test evidence.

For fabricators and installers, proven systems reduce risk. Clear test data and defined configurations mean fewer unknowns during fabrication and installation. In a market where margins and timelines are tight, reliability matters.

The evolving role of a systems house
As compliance requirements grow, the role of a systems house has evolved. It’s no longer just about supplying profiles.

It’s about providing clarity around testing scope, configuration limits and compatible hardware. Good technical support, documentation and training help ensure what is specified is what gets delivered on site.

That clarity benefits the entire chain, from specification through to installation.

Performance and design go hand in hand
None of this means design has taken a back seat. Aluminium’s appeal still lies in its clean lines, strength and flexibility.

Internal glazing is a good example. Systems like ID30 support the continued demand for glazed partitions and screens in offices, education and hospitality spaces, but its value goes beyond looks.
When one well-engineered system can deliver hinged, pivot, sliding, folding, bi-fold and telescopic doors from a single, consistent profile set, it helps maintain sightlines and detailing while also simplifying fabrication and specification.

That matters to fabricators managing efficiency and to designers seeking cohesion across a project. It also reflects how glazed partitions are now shaping modern homes as well as commercial spaces.
Design-led solutions can still be practical and installer-friendly, when they are properly engineered and tested.

A positive direction for the industry
The direction of travel in 2026 is a positive one. Greater focus on realistic testing, verified performance and open technical dialogue ultimately leads to better outcomes for buildings and their users.
For systems houses, the priority is simple: invest in meaningful testing, be transparent about capabilities and support customers with practical expertise.

Because long-term confidence is built on what can be demonstrated, not just what can be declared.
