Aluminium Internal Doors: The Complete Buyer’s Guide
Aluminium internal doors have become a popular design feature in modern homes, offices and commercial spaces.
Combining slim sightlines, large glazed panels and a distinctive steel-look appearance, they’re a stylish way to divide your space while maintaining natural light and an open feel.
At Exeter Trade Aluminium, we fabricate and supply aluminium internal doors throughout the South West.
We work with homeowners, installers, builders and developers on a wide range of projects, from home renovations and extensions to new-build developments and commercial fit-outs.
In recent years, we have seen a significant rise in the popularity of steel-look internal doors. Open-plan living remains a hot topic for homeowners, but many are now seeking greater flexibility from their living spaces.
Internal glazing systems help design-conscious buyers separate their rooms with a contemporary feature that also adds value and visual appeal.
Manufacturers have responded to the growing demand for internal doors, and there is now a plethora of options on the market, at every price point. However, choosing the right system can be challenging.
Prices, specifications, sightlines, glass options and lead times can vary considerably between manufacturers.
In this guide, we’ll explain everything you need to know before investing in aluminium internal doors. We’ll cover costs, lead times, design options, maintenance requirements and the key differences between aluminium and steel systems.
We’ll also share practical advice based on our experience fabricating and supplying these products, helping you make an informed decision for your project.

Aluminium vs Steel Internal Doors
At first glance, aluminium and steel internal doors can look remarkably similar.
Both offer slim frames, large glazed panels and a contemporary aesthetic that complements a wide range of interior styles.
However, there are several important differences between the two materials that can influence everything from cost and lead times to weight, maintenance and long-term suitability.
Choosing between aluminium and steel is more than just which look you prefer. The right choice will depend on your budget, the style of your property, your project timescales and the look you’re trying to achieve.
Opting for aluminium can help you create a crittall-style internal door for a significantly reduced cost.
Understanding these differences will help you choose the system that’s best suited to your project.

Styling Aluminium Internal Doors
We regularly see homeowners and developers choose steel-look internal doors for open-plan kitchen projects and home office renovations. They create room separation without blocking natural light.
Whether you’re trying to achieve privacy or a more flexible living space, black Crittall-style internal doors offer a sleek aesthetic and a versatile function.
For most residential projects, aluminium systems such as the Cortizo Design 35 can achieve a similar aesthetic to traditional steel systems at a significantly lower cost.
Where our aluminium doors thrive is by allowing homeowners the opportunity to create high-quality designer internal doors, in various configurations, for a fraction of the cost when compared to similar steel alternatives.
Typical Lead Times
Our typical lead time for aluminium internal doors starts from around 2-3 weeks from order.
We’re constantly updating our lead times, which are always available to browse on our website.
Lead times can vary considerably depending on the system and configuration you’re searching for.
All of our Cortizo internal doors are fabricated at our Exeter facility using profiles, hardware and components held in stock locally.
This gives us greater control over production schedules and helps us maintain consistent lead times throughout the year.
What Should You Look for When Comparing Systems?
When choosing your internal door system, it’s important to look beyond aesthetics alone.
Consider factors such as the quality of profile, sightlines, hardware, lead times, technical support and installation considerations.
Plus, the experience of your fabricator. These are all significant factors that could impact your finished product.
It’s also worth considering where your doors will be made and who will be manufacturing them. While some suppliers act purely as resellers, we manufacture our products in-house, giving us greater quality control, production schedules and technical support.
If possible, visit a showroom and see the product in person before making a decision. This gives you the opportunity to assess the build quality, understand the available design options and speak directly with the people behind the product.
We fabricate our internal doors within our two fantastic production facilities.
The Design 35 Internal Door is also on display in our showroom, allowing homeowners, builders, developers and installers to view the system up close, explore configuration options and gain a better understanding of how it could work within their project.
For many customers, being able to see where their doors are manufactured and meet the team producing them provides additional confidence in the product they’re choosing.
