Aluminium Casement Windows
Crisp Lines & Lasting Strength
At UGS Ltd, our aluminium casement windows offer a sleek, modern solution for homeowners seeking a combination of strength, durability, and style. Aluminium is known for its exceptional durability and low-maintenance qualities, making it an ideal material for casement windows. With their outward-opening design and versatile operation, aluminium casement windows provide excellent ventilation, security, and ease of use, making them a popular choice for contemporary and traditional homes alike.
Aluminium casement windows are highly energy-efficient due to advanced thermal break technology, which minimises heat transfer and improves insulation. Combined with high-performance glazing options, these windows help to keep your home warm in winter and cool in summer, reducing energy costs and contributing to a more comfortable living environment. The slimline frames of aluminium casement windows allow for larger glass areas, maximising natural light and creating a bright, open feel in your home.
One of the main advantages of aluminium is its resistance to rust, corrosion, and warping, making it a long-lasting and low-maintenance option. Aluminium casement windows require minimal upkeep, as they retain their appearance and performance without the need for frequent repairs or treatments. Available in a wide range of colors and finishes, including powder-coated options, aluminium casement windows can be fully customised to complement your home’s style, whether modern or traditional.
At UGS Ltd, we offer high-quality aluminium casement windows that deliver both aesthetic appeal and long-lasting performance. These windows are designed with security in mind, featuring robust frames and multi-point locking systems for enhanced protection. Whether you’re looking to enhance the sleek, contemporary look of your home or seeking a durable, energy-efficient window solution, aluminium casement windows provide the perfect balance of style, strength, and functionality.

Profile
At UGS Ltd, we supply and install Aluminium Casement windows in three distinct profiles—Standard, Slim and Flush—each offering a unique blend of style and performance.
Standard Profile
At UGS Ltd, we are proud to partner with industry-leading aluminium profile manufacturers such as Schüco, Reynaers, Cortizo, and Smart to offer premium aluminium casement windows at competitive prices. Our standard profile casement windows are available with a wide range of personalisation options, allowing each window to be tailored to meet the exact specifications of your project—from standard sizes to fully bespoke designs.
Our standard profile aluminium casement windows provide a strong, reliable solution for both residential and commercial properties. Typically, these profiles feature a frame depth of 70–75mm and a sash depth of approximately 65–75mm, ensuring outstanding structural strength, long-term durability, and excellent compatibility with double or triple glazing. This makes them particularly suitable for larger window openings, offering superior performance in terms of thermal insulation, security, and noise reduction.
One of the key advantages of the standard profile is its ability to support expansive glass areas, allowing more natural light to enter the room and create a brighter, more open feel. Despite their robust construction, the profiles incorporate advanced thermal break technology, which reduces heat transfer and helps maintain consistent indoor temperatures—improving energy efficiency and potentially lowering heating bills.
Aluminium as a material is also naturally resistant to corrosion, warping, and weathering, making these windows a long-lasting, low-maintenance choice. Even with their thicker frame, standard profiles deliver sleek, modern aesthetics with relatively slim sightlines, balancing strength with visual elegance.
Available in a diverse palette of colours and finishes—including powder-coated and textured options—our aluminium casement windows can be fully customised to complement any architectural style, from contemporary extensions to traditional renovations. Hardware choices and opening configurations can also be tailored to suit practical needs and design preferences.
Slim (Heritage)
At UGS Ltd, our slim (heritage) aluminium profile casement windows are designed to offer a minimalist, elegant appearance while delivering all the benefits of modern window technology. With a frame depth typically between 60–65mm and sash depths of 50–60mm, the slim profile allows for larger glass areas and slimmer sightlines, making it ideal for maximising natural light and offering uninterrupted views. This makes the slim profile especially popular in homes seeking a brighter, more open feel with subtle, contemporary detailing.
Compared to the standard profile, which has a thicker, more prominent frame, the slim profile presents a more refined and lightweight aesthetic. It is perfectly suited to projects where design priorities include clean lines, architectural simplicity, and a seamless visual connection between inside and out. Though more delicate in appearance, it retains the inherent strength and durability of aluminium, ensuring long-term performance with minimal maintenance.
Both the slim and standard profiles feature advanced thermal break technology, which helps to reduce heat transfer and improve energy efficiency. While the slim profile may provide slightly lower insulation and security levels than the standard profile in large-scale installations, it still delivers strong thermal performance, particularly when paired with high-quality glazing.
The slim aluminium profile is also highly resistant to corrosion, warping, and weather exposure, making it a practical, long-lasting choice. Its discreet frame is often favoured in modern residential settings, smaller spaces, or heritage-style buildings where understated design is essential.
Available in a wide selection of finishes, colours, and hardware options, our slim profile aluminium casement windows can be tailored to suit both modern and traditional properties. Whether you're enhancing a contemporary extension or updating a period-style home, the slim profile offers a perfect balance between aesthetic sophistication and everyday functionality.
Flush
The flush aluminium profile casement windows are expertly crafted for those seeking a clean, modern aesthetic without compromising on strength or energy performance. The defining feature of the flush profile is that the window sash sits level with the outer frame when closed, creating a flat, streamlined appearance. With a typical frame depth of 65–70mm, this profile is ideal for contemporary homes or projects requiring sleek, architectural detailing.
When compared to the standard profile—usually 70–75mm deep—the flush profile offers a more minimalist finish. While the standard frame provides greater thickness for enhanced insulation and structural strength, the flush profile achieves visual balance and simplicity. It still maintains excellent thermal performance and security, but with a subtler, more integrated look that suits both residential and commercial applications.
In contrast to the slim (heritage) profile—typically 60–65mm deep and designed for replicating traditional or period-style windows—the flush profile leans firmly into modern minimalism. Slim profiles are ideal for maximising glass area and preserving historical detail, whereas the flush profile provides a more uniform, contemporary appearance that blends seamlessly with the building envelope.
Despite its understated frame, the flush aluminium profile retains the core benefits of modern aluminium systems, including advanced thermal break technology for improved insulation, weather resistance, and durability. It also offers a good balance between slender sightlines and structural integrity, making it a versatile choice for various property styles.
Flush casement windows are particularly effective in new-builds, extensions, or renovations where clean edges and seamless transitions are key design priorities. They’re also low-maintenance and available in a wide range of colours, finishes, and hardware styles to complement any architectural scheme.
At UGS Ltd, our aluminium casement windows are available with both double and triple glazing options to provide superior energy efficiency and comfort for your home. Whether you choose double or triple glazing, both offer excellent thermal insulation and noise reduction, making your home more comfortable and energy-efficient year-round.
For enhanced performance, our glazing units can be filled with argon gas, an inert gas that increases thermal efficiency by reducing heat transfer through the glass. Argon-filled windows also help to reduce condensation buildup and improve overall energy savings, ensuring a warm, comfortable environment while lowering energy bills.
For character properties or listed buildings where replacing the original windows is not possible, secondary glazing units are the ideal solution. They preserve the exterior charm while significantly improving insulation and noise reduction. To learn more, visit our Secondary Glazing Unit page for more details on how this can be the perfect upgrade.
