Casement Windows by Material
uPVC Casement Windows
uPVC casement windows offer a clean, versatile design with excellent thermal efficiency and secure locking. Low-maintenance and cost-effective, they provide long-lasting performance and a practical solution for maximising light, ventilation, and energy savings in both traditional and modern homes.
Alu Casement Windows
Aluminium casement windows feature slim, strong frames that maximise glass area and light. Combining durability with minimal upkeep, they deliver a sleek, contemporary look and exceptional weather resistance, perfect for modern properties seeking a refined and long-lasting window solution.
Timber Casement Windows
Timber casement windows bring natural elegance and outstanding insulation, crafted to complement period or character homes. Their timeless style and bespoke finish add warmth and authenticity, with regular maintenance preserving their beauty and performance for generations to enjoy.
uPVC Timber-look Window Collection
Timber-look uPVC windows replicate the appearance of traditional timber while offering superior insulation and minimal upkeep. This range includes Heritage Flush Sash, Flush Casement, and Bay & Bow windows, combining classic style with the benefits of modern materials and durability.
Manufacturers list
Profile
At UGS Ltd, we supply and install casements in three distinct profiles—Standard, Slim, and Flush—each offering a unique blend of style and performance. Available in uPVC, aluminium, and timber, every profile is tailored to suit different architectural styles and homeowner preferences.
Standard Profile
At UGS Ltd, we work with leading manufacturers including Cortizo, Deceuninck, Kommerling, Rehau, Reynaers, Schüco, and SMART to supply and install casement windows in high-quality profiles across uPVC, aluminium, and timber.
Standard profile casement windows typically feature frame depths of around 70mm in uPVC, 75–80mm in aluminium, and approximately 78mm in timber, depending on the chosen system. These profiles offer a classic, well-proportioned appearance with slightly thicker frames, making them ideal for both traditional and contemporary properties.
The standard profile is engineered for strength and durability, providing excellent thermal insulation, soundproofing, and weather resistance. Its substantial frame enhances structural integrity and supports larger openings, offering practical benefits without compromising on style. This makes it particularly well-suited to period homes or properties where a more defined frame is preferred.
While slim and flush profiles provide a sleeker look with increased glazing area, the standard profile remains a popular choice for homeowners who value a balance of elegance, robustness, and long-term performance. It delivers the timeless charm of a classic casement window while meeting modern energy efficiency and security standards.
With a variety of customisation options available, our standard profile casement windows provide a reliable and attractive solution for any project, combining traditional styling with contemporary functionality.
Slim Profile
Slim profile casement windows offer a refined, contemporary look with narrower sightlines that maximise the glazed area and allow more natural light into the room. Typically, slim profiles measure around 65–70mm in uPVC, 60–72mm in aluminium, and approximately 68mm in timber, depending on the system.
These frames are designed to suit homeowners and designers seeking a minimalist finish without compromising on performance. The slim design is particularly well suited to modern homes, renovations, or properties in conservation areas where maintaining a lighter, more elegant frame is essential.
Despite the reduced frame thickness, slim profile casement windows still deliver excellent thermal insulation, soundproofing, and security. They accommodate double or triple glazing, helping to reduce heat loss and lower energy costs while offering a sleek visual finish.
The clean, understated frame draws attention to the glazing itself, enhancing views and contributing to a more open, spacious feel indoors. Their design also allows for smooth operation and can be customised to suit a wide range of styles and finishes.
Whether for contemporary builds or subtle upgrades to traditional homes, slim profile casement windows provide a stylish and high-performing solution. They are an excellent choice for those looking to combine aesthetics with energy efficiency, security, and modern functionality.
Flush Profile
Flush profile casement windows offer a clean, streamlined appearance where the sash sits level with the outer frame, creating a flat, uniform surface when closed. This design delivers a contemporary yet timeless look that suits both modern homes and traditional properties seeking a more subtle, refined finish.
Unlike standard profiles with a stepped sash or slim profiles with minimal framing, the flush profile provides a balanced aesthetic—removing protrusions and creating a smooth, cohesive edge. This makes flush casement windows ideal for those wanting a minimalist architectural style without sacrificing the character of their property.
Flush profile casement windows still offer high performance in insulation, soundproofing, and security. The close-fitting design supports improved thermal efficiency, helping to reduce energy costs while maintaining comfort throughout the year. The integrated structure also enhances security, with multi-point locking systems fitting seamlessly into the frame.
These windows can be customised to suit a range of property styles and are available in a wide selection of finishes. Their smooth lines make them ideal for modern builds, while their understated appearance also complements heritage homes or conservation areas where a sensitive, modern upgrade is needed.
Flush profile casement windows are a perfect choice for homeowners looking to blend visual simplicity with durability, energy efficiency, and secure functionality.
At UGS Ltd, our 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.
