Choice has powered aluminium’s growth. But when specification becomes overwhelming, sales slow. Silka managing director, Asa McGillian, argues the market now needs simpler, structured offers.

Over the last decade, aluminium has become one of the most design-led and versatile materials in the glazing industry. Colour options, performance, hardware choices, configurations and upgrades have all expanded dramatically.

That flexibility has been central to aluminium’s success. It allows systems to be adapted to almost any project – from contemporary extensions to large, glazed elevations and high-end renovations.

But in a challenging market, complexity becomes a problem, and too much choice slows sales down. A single project can involve multiple configurations, glazing options, colours and upgrade combinations. In many cases, installers are preparing several variations of the same quote just to help customers understand their options.

Homeowners are researching projects more than ever. They’re requesting multiple quotes, comparing specifications and making decisions quickly. At Silka, we’re seeing the installer who can respond clearly and confidently take the advantage, and that’s where our 30 years of expertise, and the level of support we can offer as a result, really comes into its own.

When choice becomes friction
We need to talk about the difference between flexibility and clarity. Aluminium systems are designed to be adaptable, but installers don’t always need dozens of different iterations to secure the job.

What lands sales in 2026 are clear, structured solutions they can quote quickly and present with confidence.

The difference between winning and losing a project can come down to how quickly an installer can put forward a strong, well-explained proposal. If specification becomes overly complicated, it eats into time, margin and confidence at that critical point of sale.

Our industry needs to shift its thinking. Not away from flexibility, but towards making specification easier to navigate. Rather than expecting installers and customers to work through every possible configuration, we’re starting to see greater focus on more confident, curated specification – offers where the core elements are already defined.

Simplifying the specification process
Suppliers need to think about how to structure their systems as packages, particularly around high-demand products like bi-fold doors. There’s growing value in defining the core product clearly from the outset. Not removing choice, but making the starting point stronger.
For installers, the benefits are straightforward. It cuts down time spent navigating specifications, makes quotes easier to prepare and keeps conversations with homeowners focused on the project itself.

It can also help protect margin. When stronger elements are built into the core product – whether that’s higher-performance glazing or integrated features – installers begin with a better solution from the outset, rather than relying on upgrades later.

We’re continually simplifying things at Silka so installers aren’t battling complexity at quote stage, which means moving from enquiry to order faster, and with more confidence.

One example is our recent Silka aluminium bi-fold doors offer. We fixed the trade price per leaf and defined the core configuration upfront, including Softcoat Low-E glazing, argon gas and factory-fitted integral blinds. That provided installers with a premium aluminium bi-fold they can quote quickly, and present clearly. No complicated options. No uncertainty around pricing. Just a strong product that’s ready to transform a home in time for summer.

Choice will always remain one of aluminium’s strengths, particularly on complex projects where flexibility matters. But the way that choice is structured should evolve.

Aluminium isn’t short of options. The real challenge now is helping installers navigate them quickly enough to win the job – without losing margin, or their nerve, along the way.
