Bespoke Windows by Material
Aluminum Windows
Aluminium windows feature slim, modern frames that maximise glass area and light. Exceptionally strong and weather-resistant, they provide a contemporary look with minimal maintenance.
Timber Windows
Timber windows deliver natural warmth and traditional charm with outstanding insulation and bespoke craftsmanship—their classic style suits heritage or character homes, yet they require periodic upkeep.
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 Flush Sash Casement, and Flush Sash Bay & Bow windows.
Bespoke Windows Types
Bay & Bow Windows
Bay and bow windows project outward to create extra space and flood interiors with natural light. Their fixed and opening sections combine style and ventilation, adding architectural character and enhancing views for both traditional and contemporary properties.
Tilt & Turn Windows
Tilt and turn windows offer dual functionality, tilting inwards for secure ventilation or fully opening like a casement for easy cleaning. Their clever design suits modern living, providing excellent airflow control and a sleek, versatile appearance.
Arched Windows
Arched windows introduce soft curves and elegance, framing views with a distinctive architectural feature. Typically fixed but customisable with opening sections, they add character, natural light, and a graceful focal point suited to both classic and contemporary designs.
Casement Windows
Casement windows are hinged at the side and open outwards, allowing excellent airflow and clear, unobstructed views. Simple, versatile, and energy-efficient, they suit virtually any property style, offering practicality, security, and a timeless, understated appearance.
Vertical Sliders (Sash Windows)
Vertical slider windows operate by sliding one or both sashes vertically, preserving space and offering controlled ventilation. Classic in style, they’re ideal for heritage homes or period-inspired designs, delivering charm and smooth operation with a traditional aesthetic.
Secondary Glazing Units
Secondary glazing, also called secondary windows or secondaries, involves adding a discreet internal window to existing frames. This cost-effective solution improves insulation, reduces noise, and enhances energy efficiency without altering your property’s external appearance or original windows.

Window Profiles
When choosing windows, the profile type plays a crucial role in both aesthetics and performance. At UGS Ltd, we offer a wide selection of standard and slim profiles, allowing you to find the perfect balance between design, functionality, and energy efficiency for your project.
Standard
Offer a robust and traditional frame appearance, providing excellent insulation, durability, and support for larger glass panes. These profiles are ideal for those who prioritise structural integrity and maximum thermal performance. Standard profiles are typically more common and versatile, allowing for larger glass panes and providing excellent insulation. The wider frame also supports more customisation options in terms of materials and finishes. While they offer great structural support, they can sometimes reduce the amount of visible glass, which slightly affects the natural light entering your space.
Slim
Slim window profiles maximise the visible glass area by reducing the thickness of the frame, creating brighter interiors and uninterrupted views. This design is particularly valued in contemporary architecture where light, openness, and minimalist aesthetics are priorities. In addition to their elegant appearance, slim profiles provide reliable durability and modern performance, though they may not be available across all window materials or opening types. For tailored guidance on whether slim profiles suit your chosen style, please explore our dedicated window type and material pages for more detailed information.
Flush
Flush profile windows feature a sleek design where the sash sits neatly within the frame, creating a smooth, streamlined appearance. This mechanism not only enhances aesthetics but also improves insulation and security while reducing maintenance demands. Flush profiles are particularly popular for achieving a clean, contemporary look or replicating traditional timber finishes with modern benefits. However, they are not suitable for every window style or material type. To explore compatibility and discover the best options for your property, please visit our dedicated window type and material pages.

Personalisation Windows Features Offered by UGS Ltd
At UGS Ltd, we believe that every window should not only deliver on performance but also reflect your individual style and practical requirements. That’s why all our window products—whether classic or bespoke—come with a wide range of personalisation options. From casement and sash to tilt-and-turn and fixed units, our customisation features ensure your windows complement your property while offering outstanding energy efficiency and security.
Opening Configurations
Every window style can be tailored with different opening configurations to suit the layout and ventilation needs of your space. Whether you prefer side-hung, top-hung, sliding sashes, or tilt-and-turn mechanisms, we ensure each window operates smoothly and integrates seamlessly into your property’s design.
Locking Mechanisms
Security is a priority, and all our windows are fitted with UKAS-approved locking systems as standard. For enhanced protection, we offer multi-point locking, child-safety restrictors, and high-security upgrades including anti-drill and anti-snap components. We also offer optional smart-lock integrations for selected window types, combining technology with peace of mind.
Window Accessories
Our windows can be personalised further with a variety of accessories. From handle styles and hinge colours to trickle vents, restrictors, and glazing bars, each detail can be selected to enhance functionality and aesthetic consistency. These accessories are available in various finishes to suit both modern and traditional tastes.
Colour Options Inside and Out
UGS Ltd offers a broad spectrum of colour choices to personalise the inside and outside of your windows. Opt for matching or dual-colour finishes to coordinate with both interior décor and external façades. From subtle woodgrain effects to bold contemporary tones, our finishes are long-lasting and low-maintenance, tailored to your vision.
Glazing Options
We provide a comprehensive selection of glazing options that prioritise performance and style. Choose from double or triple glazed units, by standard filled with Argon gas for improved thermal insulation. For additional character, Pilkington decorative glass designs are available, offering a range of textures and patterns that enhance privacy while maintaining natural light.
