Frame the view. Shape the space.

The right window design does more than fill an opening. Slim aluminium sightlines can help maximise visible glass, bring more natural light into the room, and create cleaner architectural lines.

It’s why frame proportions, mullion positions, and overall sightlines are worth considering early in the project, not just the colour or finish.

Glass technology that helps reduce cleaning needs.

Some glass options use a dual-action external coating designed to help keep the surface cleaner for longer.

Here’s how it works:

• Daylight helps loosen organic dirt
• Rain then spreads across the surface to help wash it away more evenly

It’s a practical option for glazed areas that are harder to reach, such as roof glazing and large glazed elevations.

Important to note: it can reduce cleaning needs, but it does not mean zero maintenance.

If you’re comparing glazing options for a project, our team can help you choose the right specification.

Choosing an aluminium sash window? The profile is only part of the decision.

The right vertical slider should also be considered for:

• Sightlines and visible glass
• Ease of cleaning and access
• Thermal construction
• Permitted sizes and configurations
• The architectural style of the property

A good-looking frame still needs to work for the opening, the building and the people using it.

A coordinated finish can completely change the look of a property.

This installation pairs black aluminium windows with matching glazed doors to create a clean, consistent look across the rear of the home.

Slim frames and carefully positioned glazing bars add definition without making the openings feel heavy, while the larger glazed areas help connect the living space with the garden.

Divide the space. Keep the light.

Internal aluminium room dividers give you separation without making the space feel closed off.

They can work particularly well for:

• Creating a dedicated home office while keeping natural light flowing
• Separating a kitchen and dining area without building a solid wall
• Creating a flexible living zone that can adapt as the space is used differently

Depending on the configuration, options such as sliding panels, low thresholds and clear or obscure glazing can add even more flexibility.

Designed specifically as an internal partition system.

What does a thermal break actually do in an aluminium window?

Aluminium conducts heat efficiently. In a thermally broken aluminium system, a separating barrier between the inner and outer sections of the frame helps reduce the direct path for heat transfer.

That can contribute to better thermal performance, but the frame is only one part of the system. The glazing, seals, specification and quality of installation all matter too.

So when comparing aluminium windows and doors, look beyond the glass alone. The complete system determines the final performance.

More daylight shouldn’t mean an overheated room.

Large areas of glazing can completely transform a home — but summer comfort needs to be considered before the glazing specification is finalised.

It’s not about relying on one product to solve overheating. The best results come from looking at the whole design:

☀️ The orientation and sun path
🪟 The amount of glass compared with solid wall
🌡️ Appropriate solar-control glazing
🌤️ External shading where suitable
💨 Opening sizes and the ventilation strategy

These decisions work together to influence daylight, solar gain and how comfortable the space feels during warmer months.

Planning a glazed extension, renovation or new-build project? Speak to our team before the elevations and glazing specification are locked in.

The frame can change how the whole room feels.

When planning large areas of glazing, it’s not just the overall window size that matters.

Slim sightlines can increase the amount of visible glass, while the position of mullions and transoms can influence daylight, views, interior proportions, and even the rhythm of the exterior elevation.

These details are much easier to get right before the elevations are finalised.

Planning an August or September project? Now is the time to confirm the details.

A smoother installation starts well before the delivery date. Finalising your sizes, system, colour, glass, hardware, and quantities early gives enough time for quoting, approval, manufacture, and delivery.

Working backwards from installation also helps reduce last-minute changes that could affect the schedule.
