Profile

At UGS Ltd, we supply and install uPVC windows in two profiles—Standard and Flush—each offering a unique blend of style and performance. Every profile is tailored to suit different architectural styles and homeowner preferences.

  • Rehau logo
  • Kommerling logo
Standart window upvc profile

Standard

At UGS Ltd, we work with some of the leading brands in the uPVC window industry, including Deceuninck, Kommerling, and Rehau, to offer top-quality products. We supply and fit a wide variety of uPVC windows, available in all sizes and styles, with the option for personalised features to suit your individual needs. Whether you’re looking for casement, sash, tilt & turn, or any other type of window, we have the perfect solution.

Our standard uPVC profiles provide excellent durability, energy efficiency, and a robust design. These profiles offer a slightly thicker frame, providing enhanced insulation and soundproofing while maintaining a classic appearance. For those seeking a more modern aesthetic, the slimmer, flush profile is an excellent alternative. Slim profiles offer a sleek, streamlined look, sitting flush against the window frame for a minimalist, contemporary finish while still providing the same high performance and energy efficiency as standard profiles.

Flush

These profiles sit level with the window frame when closed, creating a clean, minimalist look that complements contemporary architecture beautifully.

The slim frame design provides a sleek aesthetic and allows for larger glass areas, increasing the amount of natural light that enters your living space. Despite their reduced profile, these windows offer excellent thermal insulation, helping to improve energy efficiency throughout the home. Made from highly durable uPVC, they require minimal maintenance and offer the same robust strength and security as standard frames.

While slim profiles are ideal for modern designs, our standard uPVC profiles, with their slightly thicker frames, provide a more traditional appearance and marginally enhanced sound insulation. Both options offer outstanding performance. For a traditional timber aesthetic, we invite you to explore our uPVC Timber-look window page.


uPVC Window Glazing Options at UGS Ltd

At UGS Ltd, uPVC 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

Double Glazing

  • Energy rating A+
  • 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

Argon Filled

  • 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.
