Custom UPVC Windows - Affordable Prices and Energy Efficient
uPVC windows with superior performance
uPVC, also known as unplasticized polyvinyl chloride or vinyl, is a tough, synthetic and recyclable material that is easy to process. This makes customizing the size, shape and functionality of the window simple. In addition, it provides homeowners with excellent long-term durability and low maintenance requirements. Today, modern windows must meet and balance a range of requirements from aesthetics to functionality. These requirements include:
- Natural light
- Provide fresh air
- Insulation
- Safety
- Reduced noise
- Match with interior and exterior
- Protect from weather effects, including sunlight
We also offer different types of profiles, including aluminum and aluminum clad wood, which can completely customize the windows to your needs. From this, you can further choose the finish and color to meet your exact needs in terms of style and function. This includes special glass for insulation, acoustic insulation or security as well as custom colors and hardware.
Insulation
Essentially, a window is a large hole in the exterior wall, so having a quality uPVC window is essential. Grandsea windows and doors provide excellent protection from the elements while preventing temperature changes and energy loss. Whether you live in a warm area and want to maintain a cool interior temperature, or live in a cold climate and want to prevent heat loss, windows play a much larger role in a building's overall energy loss than their size.
Our uPVC profiles are available in a variety of configurations, with multiple internal chambers and optional insulating foam fillings to further improve their insulating properties, resulting in significant energy savings.
Glazing
Glass also plays a vital role in the overall U-value and insulating ability of a window. The total surface area of glass is much larger than the frame and sash, so the choice of glazing configuration is crucial. Today's options include double and triple glazing, and if you have a strong desire for thermal insulation, we recommend triple glazing for all replacement and new build windows.
Finally, the space between each pane of glass can also be filled with a gas such as argon, which has lower thermal conductivity than ordinary air. This makes it more difficult for heat to pass through the window, thereby improving the window's insulating effectiveness.
uPVC windows for outstanding design and appearance
Due to its flexibility, uPVC is very easy to process. Therefore, components of this material are available in a wide range of shapes, such as round windows, trapezoidal windows and other special-shaped windows.
uPVC is a synthetic material that is very easy to process during the manufacturing process. This means that it is easy and cheap to choose non-rectangular shapes, which makes the production of arched, triangular shapes simple. UPVC is equally flexible in terms of color selection. Although it cannot be directly painted like wood, the entire RAL range is available. Our factory uses special foils for painting during the door and window manufacturing process. This not only provides you with countless color options, but also has the added benefit of further protecting the external frame from weather wear and minor scratches.
UPVC windows are the perfect medium for customizing shape, size, color, thermal insulation, security and noise reduction to your specific requirements. Best of all, they are not mutually exclusive. Top energy-saving windows can also have excellent security, such as triangular windows.
