uPVC Timber-look Flush Windows

Innovation that You Will Love

The rapid advancement of technology and materials has led to the development of more energy-efficient, durable, and secure windows with improved recyclability. However, looking back at traditional designs allows us to preserve the charm of architectural heritage while integrating modern benefits. Our Timber-look collection offers flush Sash, Casement and Bay&Bow windows.

More affordable than real wood, they enhance both the comfort and aesthetics of any property. Thanks to modern materials and manufacturing techniques, they offer superior insulation and require minimal upkeep.

While real timber is undeniably beautiful, it is prone to swelling, shrinking, warping, and twisting due to weather conditions. Maintaining wooden frames is both costly and time-consuming, whereas Timber-look Heritage windows retain their appearance without the need for ongoing maintenance. Their flush exterior, combined with a classic mortise and tenon-style finish, replicates the elegance of heritage casement windows while incorporating modern efficiency. With a diverse range of period colours and textured wood-effect finishes, Timber-look windows complement various property styles. Request you Free Quote Now.

Authentic Design with Modern Performance

Explained

With features such as an optional deep bottom rail and concealed external
trickle ventilation, the external appearance of Timber-look Flush Sash
Windows is almost indistinguishable from premium flush timber frames.
Designed to replicate traditional craftsmanship, this uPVC Flush Sash Window.

Timber-look Fush Casement windows closely resemble traditional timber frames but come with significant advantages of uPVC. System incorporates a square mortise and tenon-style fabrication for both
the sash and outer frame, eliminating the visible mitred joints typically
associated with uPVC windows.

Timber-look uPVC Window Glazing Options

At UGS Ltd, uPVC Timber-Look windows are available with both double and triple glazing. Every unit comes with argon gas filling as standard, ensuring excellent energy efficiency, reduced heat loss, and improved comfort throughout your home.

Double glazing option

  • R value 1.2-1.6 W/m2*K
  • U value 1.2
  • G value 0.71
Tripple glazing option

Tripple Glazing

  • Energy rating A++
  • R value 0.7-1.0 W/m2*K
  • U value 0.9
  • G value 0.61
Argon filled glazing option

  • Energy rating Improved
  • R value Up to 30% higher
  • U value Up to 25–30% lower
  • G value no signifficant affect

*Energy Rating show overall energy efficiency of the product. The entire window (the frame and the glass) is assessed to allow for heat loss, draughts and solar gain, giving a rating that indicates the overall impact of fitting that window in your home.
*The R Value Measures resistance to heat gain or loss. Example, a typical insulated wall has an R-value anywhere from 12 to 19.
*The U Value of the glass tells us heat loss through the glass, the glass edge and the frame.
*The G Value of the glass tells us how well the glass transmits heat from the sun.

Double Glazing 

A popular option, double glazing consists of two glass panes with a gap between them, which significantly reduces heat loss, helps with soundproofing, and enhances overall security.

 

Tripple Glazing 

For even greater performance, triple glazing includes a third pane of glass, offering enhanced insulation, better soundproofing, and improved energy efficiency, making it ideal for colder climates or areas with high levels of external noise.

Benefits of Argon Gas Filling

Both our double and triple glazing units are filled with Argon gas, which is denser than air. This gas filling provides additional insulation by reducing heat transfer through the glass, helping to maintain a consistent temperature in your home. 


Timber-Look uPVC: Relevance and Compliance

Conservation & Planning

When developing the Timber-look glazing system, careful attention was given to the Article 4 Conservation Area Guidelines for Windows. By combining these principles with modern technology and cost-effective materials, we have created secure, energy-efficient products that retain the traditional charm of period properties.

Local authorities are increasingly approving Timber-Look Flush Sash Windows for use in conservation areas and listed buildings. More and more councils recognise their authentic appearance, acknowledging that they successfully replicate traditional flush casements while maintaining key heritage details such as the cill and trickle ventilation. Their design ensures a seamless blend of classic aesthetics with modern performance, making them a preferred choice for heritage projects.

New Build Projects

When selecting windows and doors for a new-build property, they must comply with current building regulations, whether for a single home or a larger development.

Timber-look windows meet Document Q standards, having undergone independent testing. With enhanced glass and hardware, they are also PAS24 certified, ensuring they meet security requirements set by building inspectors.

As these are separate standards, if not installed by UGS Ltd, it is essential to discuss them with your local installer when specifying your project.


Wide range of options

At UGS Ltd, we customise Timber-Look windows and doors to suitany home or project. Choose between the sleek contemporary shallow cill or the elegant Radlington Cill for a refined touch. Enhance your windows with Astragal, Georgian, or Leaded bars, and opt for double or tripple glazing for added efficiency. A range of hardware finishes ensures a perfect match for any style. Available in single or dual colours, our units offer a vast palette for both classic and modern designs. UGS Ltd combines quality craftsmanship with complete personalisation.

Article 4 is a planning regulation used by local councils to remove certain Permitted Development Rights in conservation areas or areas of special interest. If Article 4 applies to your area, it means you may need planning permission for changes that would normally not require it - such as replacing your windows.
