Slimline aluminium windows and doors have become one of the most popular modern industry design trends in recent years.
With homeowners looking to maximise the amount of natural light in their properties, manufacturers have continued to push engineering boundaries to create increasingly slim profiles to meet the demands of the consumer.
Slimline Aluminium Windows consist of a drastically thinner profile with the ambition of maximising the viewing area from a larger pane of glass.
Aluminium is far more durable than rival alternatives like uPVC. This means that the homeowner reaps all the rewards of a large glass viewing space, allowing natural light to flood into their property, as well as high levels of security and thermal performance.
One of the most common industry trends over recent years has been the desire to create a more connected living space that blends our indoor and outdoor living opportunities.
A recent study from IPA TouchPoints found that the average person spends 18 hours and 43 minutes at home per day. This is an increase of an hour and six minutes on data recorded before the 2020 lockdowns.
As we spend more time indoors, manufacturers, like AluK have been predicting a growing trend towards creating a connected indoor and outdoor living space, which could reflect the rise in popularity of the slimline style.
Aspect Windows Sales Supervisor Chris King explains why it has become such a popular choice among consumers, “The Slimline style is the most effective method of maximising the natural light you let into your property and making the most of your outside views.”
A slimline style is now available on several different products that can be utilised throughout your home.
If you’re looking to create a cohesive slimline style in your home, we’ve created this helpful guide that details some of the most popular slimline products available.

The AluK 58BW Slimline Flush Window is the perfect solution if you’re looking to create an eye-catching design from both the interior and exterior of your home.
The ultra-slim 45mm sash ensures the 58BW is suitable for properties ranging from modern new build to a traditional renovation project.
It offers fantastic thermal performance with U-Values of 1.5 W/m2K and is available in a variety of configurations.

The Origin OB-36+ Gallery is one of the standout choices for a slimline bi-fold door, with sightlines of just 36mm.
Both stylish and functional, the addition of bi-fold doors can elevate the living space of any property looking to achieve a more connected and accessible space.
With a clean and simple design, the Origin OB-36+ Gallery is the epitome of timeless.
Featuring large panes of glass with an ultra-slim profile, it offers extensive, uninterrupted views of your outdoor space.
Beyond its exceptional design, the Origin OB-36+ Gallery Collection is a high-performing bi-folding door built for now and the future. It is already 2025 Future Homes Standard, and through its PAS24:2022 Accreditation, you have further peace of mind.
Excellent thermal performance is guaranteed with a U-value of 0.78W/m2K, ensuring your home remains cool in the summer and warm in the winter.
Aspect Windows sales consultant Lee Cosgrove explains why the OB-36+ Gallery Collection is one of the best on the market, “The OB-36+ is an industry-leading bi-folding door, perfect if you’re looking to maximise the natural light coming into your home. The ultra-slim sightlines are perfect for modern aesthetics and can fit into multiple property styles.
“It is a high-functioning bi-folding door that meets the latest industry regulations, and it is protected by industry-leading warranties for additional peace of mind.”

Ultraline designed the Slim Sliding Door with one clear message in mind, “More of a view”, and they made sure it delivered that and more.
It is one of the slimmest products on the market with sightlines of just 20mm throughout the visible system. Designed with a minimalist style, it is the perfect choice for any homeowner or property where there are large openings that create the opportunity to perfectly frame your outside space.
Complementing the stunning design is an incredibly efficient Sliding Door, with U-Values between 0.7 W/m2K for the triple-glazed variant and 1.2 W/m2K for the double-glazed option.
With PAS 24:2016 certification and Part Q compliance, the Ultraline slim-line sliding door is among the leading sliding doors on the market for both security and aesthetic appearance.
Choosing between a bi-folding door and sliding door is often one of the biggest debates consumers have in renovation projects, but in scenarios like this, where you’re trying to create picturesque views, the sliding door can often come out as the most suitable choice.

If you’re looking for a slimline lift and slide door to complement your wider glazing products, consider the Cortizo 4600 Plus.
Its 50mm interlock allows for the large panels of glass to take centre stage.
The combination of a sleek, slim design from Cortizo, matched with impressive thermal performance figures, makes the 4600 Plus a hugely desirable lift and slide door.

Our Slimline Roof Lantern is the perfect finishing touch to any property looking to let the natural light in from above.
By choosing a Slimline Roof Lantern against a traditional flat roof light, you’re adding additional height to the room and as a result, creating a larger, brighter, more open space.
Featuring an ultra-slim aluminium frame to optimise the external views, it features Marine Grade Powder Coated frames to withstand the harshest and most unpredictable weather conditions.
It is easy to clean and maintain, ensuring it is the final flourish of any contemporary renovation or extension.
Slim Sliding Doors helped transform this glass extension on a Grade II-listed Georgian house in Totnes.
The addition of Ultraline’s Slim Sliding Door created a functional extension that was filled with natural light and unbeatable views of their outside space.
The owners of this stunning Georgian House now enjoy near-uninterrupted views from the 20mm sightlines, in what is now a functional, inviting extension space.
