What's the Difference Between Flush Casement and Standard Casement?

While both window styles operate on a hinge system that allows them to open outward, standard casement windows feature an opening sash that protrudes slightly from the side of the frame.

In contrast, flush casement windows are designed with the opening sash sitting perfectly level with the outer frame, creating a sleek, flat surface with clean lines.  If you’d like help deciding which is best for your home, please get in touch with our team!

Weather Resistance & Thermal Efficiency

Our aluminium flush windows deliver exceptional protection against the elements, keeping your home comfortable year-round. Engineered with advanced thermal break technology and weathersealing, these windows achieve impressive U-values as low as 1.4 W/m²K with double glazing.

This helps maintain comfortable indoor temperatures, reduces energy consumption, and lowers heating costs—all while providing the sleek, contemporary aesthetics that make flush aluminium windows so sought after!

Frequently Asked Questions

Contact Us

Are flush windows any good?

Yes, flush windows are an excellent option for homeowners who want a clean, elegant appearance with strong everyday performance. The sash sits neatly in line with the frame, creating a flatter and more refined look than a standard casement window. Aluminium flush windows are especially well suited to homeowners who want slim sightlines, durability, and a contemporary take on a classic window style.

Are flush windows more expensive?

Flush windows are often more expensive than standard casement windows, depending on the material, specification, and overall design. This is usually due to their more detailed styling and premium appearance. Many homeowners choose flush windows because they offer a more refined look that works particularly well on both heritage-style and modern properties.

What is the difference between casement and flush windows?

The main difference is in the way the window sits within the frame. A standard casement window typically closes over the frame so that part of the sash projects slightly, while a flush window closes so the sash sits level with the outer frame for a flatter, more streamlined finish. Flush windows are often chosen for their more architectural appearance, while casement windows are valued for their versatility and practicality.

Can aluminium flush casement windows suit period properties?

Absolutely. While aluminium offers contemporary slim sightlines, we can incorporate traditional details like astragal bars to replicate the appearance of historical steel windows. This makes our aluminium flush casement windows suitable for period renovations and even some conservation projects where sympathetic design is essential.

Where do you source your aluminium windows from?

We partner with industry-leading manufacturers AluK and SMART Architectural Aluminium for our aluminium window systems. These renowned British suppliers are celebrated for their innovative engineering and exceptional quality standards.

Are aluminium flush casement windows environmentally friendly?

Yes, aluminium is an infinitely recyclable material, making it an excellent eco-responsible choice. It retains its properties indefinitely through the recycling process.

How energy efficient are your aluminium flush windows?

Our aluminium flush windows deliver outstanding thermal performance, achieving U-values as low 1.4 W/m²K. This exceptional thermal performance helps to reduce energy consumption and lower heating costs.
