Custom uPVC Windows
Affordable, Energy Efficient and Custom Built
uPVC Window Systems
Our line of high-quality uPVC windows is affordable and yet still a substantial step up in performance from typical domestic windows. With impressive insulation, long term durability and custom colour, design and fittings options, uPVC windows represent great value for money for those seeking to maximise performance on a budget. Whether replacement or new construction, energy savings or certified passive house, uPVC windows offer the flexibility and insulation values to cover any project's needs.
Superior Energy Performance & Custom Features
uPVC, also known as unplasticised polyvinyl chloride or just vinyl is a tough, synthetic and recyclable material that is easy to work. This makes custom sizes, shapes and features simple. Moreover, it offers great long term durability and low maintenance requirements for homeowners. Today, windows have to meet and balance a number of requirements ranging from aesthetics to function. These include:
- Natural lighting
- Providing fresh air
- Thermal insulation
- Sound reduction
- Match the interior as well as facade
- Resist weather including sunlight
We offer seven different profiles to form the basis of your custom window. From there, you can further configure them to meet your exact needs in terms of style and function. This includes special glazing for insulation, soundproofing or security as well as custom colours and hardware.
Thermal Insulating Materials
Being in essence a large hole in the facade, it is critical to have quality uPVC windows that provide excellent protection from the weather while preventing temperature changes and energy loss. Whether you live in a warm area and want to maintain a cool interior temperature or a cold climate and want to prevent heat loss, windows play a disproportionately large role in a building's overall energy loss relative to their size.
Our uPVC profiles come in a variety of configurations with multiple interior chambers and optional insulating foam fillings. Our Energeto line for example achieves Uw-values from 0.8 to 0.6 W/m²K easily beating passive house values.
Our Energeto line achieves Uw-values to 0.72 W/m²K easily beating passive house standards
Our Energeto profiles are additionally filled with an innovative polyurethane foam to further boost their insulating abilities. This new process, called precision high pressure foam, fills several interior chambers in the frame with this new foam. When combined with carbon fibre reinforced frames that eliminate the typical steel rods used, insulation performance well under passive house standards can be reached for substantial energy savings.
Glazing also plays an essential role in a window's overall U-value and insulating ability. The total surface area of the glass is much larger than the frame and sash making your choice of glazing configuration vital. Today's options include double and triple pane windows, although triple is recommended for all replacement and new construction windows nowadays. Adding warm edges (or Swiss spacers) between panes, which prevent heat transfer from one pane to the other along the edges is also wise. This prevents the creation of so-called thermal bridges which are materials which allow heat to move through the window from one component to the next leading to loss and inefficiency.
Finally, the air gaps between each pane can also be filled with gasses such as argon, which have lower thermal transmission properties than normal air. This makes it harder for heat to move through the window, thus boosting its insulation.
