uPVC Windows with an exterior Aluminium Shell - Combining great Durability with low Prices

Unplasticised polyvinyl chloride is a comprehensive solution for all of your window and door needs. With its thermal and noise insulation qualities and simultaneously excellent pricing, the material has managed to convince both construction experts and homeowners of its benefits. Following the material's success, the next advance in polyvinyl chloride technology are uPVC-aluminium windows, which combine the energy efficiency of synthetic frames with the security and durability of metal - thanks to the uPVC multi-chamber profiles and a protective outer shell manufactured from high-quality aluminium.

Combining two Methods of contemporary Fenestration

When engineers and window construction experts first had the idea to manufacture windows from affordable uPVC and durable aluminium instead of valuable timbers, initially no one thought that this idea would have much of a future. And for a sound reason, as the early uPVC and metal frames still consisted of solid material and performed far below average in terms of thermal insulation. However, today the technology is more refined and even very affordable uPVC windows can feature excellent U-values thanks to their multi-chamber profile layout. Meanwhile, windows made solely from metal can also rely on thermal insulation fillings to reach very beneficial U-values.

Currently, the bigger issue is that - despite its exceptional energy efficiency - synthetic uPVC is still slightly lacking in terms of security, as even the most robust constructions encounter problems when extreme forces are applied. In contrast, aluminium is probably the most durable material for the construction of windows, not only in regards to environmental exposure but also in terms of burglary prevention. Unfortunately, as aluminium is a type of metal it can also potentially create thermal bridges, which can transfer heat energy from the inside of the house to the outside, thus negatively affecting the overall thermal insulation. The most sensible solution for the respective disadvantages listed above would be to combine the advantages of both materials.

The materials used in uPVC-aluminium windows are almost completely recyclable and thus help to protect the environment far beyond their actual lifespan.

Basically, uPVC-aluminium composite windows are uPVC windows that are additionally protected against staining, weather influences and forceful impacts by means of a metal shell mounted to the exterior surfaces of the frame. This is similar to their wood-aluminium counterparts, which use a metal shell to protect their wooden frames against external influences. When directly comparing the two types of windows, uPVC-aluminium models do not always perform as well as wooden ones in terms of thermal insulation, but they constitute a significantly more affordable alternative.

Material and Construction

The comparatively low prices of uPVC-aluminium windows compared to those of wooden windows should not distract from the fact that both unplasticised polyvinyl chloride as well as aluminium are processed using highly advanced methods of production before assembly. All high-quality aluminium or uPVC surfaces are

  • anodised to effectively protect them against corrosion,
  • powder-coated to withstand corrosion and allow for easy lacquering
  • or made sun and weather resistant by coating them with RAL lacquers.

These surface treatment techniques guarantee window frames that combine a long lifespan with the highest possible security, even under adverse weather conditions. Additionally, they make sure that the exterior aluminium shell and the synthetic uPVC from which the interior frames are fashioned, look like new for a long time.

Security you can count on

For doors and windows, aluminium is still the most useful material when it comes to burglary protection, even surpassing wood. Non-reinforced uPVC windows can become slightly warped if strong force is applied, allowing intruders easy access to the locking mechanism. Their wooden counterparts, on the other hand, can allow burglars to illegally enter the house by first breaking apart the fibrous timber frame using heavy tools such as crowbars. In contrast to this, high-quality aluminium is almost indestructible without the use of power tools. Certainly, it cannot be easily destroyed within the timespan an intruder usually has in a residential area and under normal circumstances. Not only does the exterior shell provide protection from the forces of nature, but it also adds significantly to the overall security of your home. Combined with additional elements such as security glass or glazing bars, composite windows offer better security than those made solely from uPVC, and even exceed the burglary protection qualities of wooden frames without an exterior shell.

Familiarising yourself with the available Products

uPVC and aluminium composite windows come in a wide range of possible types and models, all of them offering their own advantages. The models of the TwinSet series, for example, are of particularly high quality, offering sophisticated 5- or 6-chamber profiles and three levels of seals, which is why they feature extremely favourable U-values between 0.60 and 0.75 W/(m2K) even with normal double glazing, meeting energy efficiency standards while limiting the installation depth required. The basic model of the TwinSet series - with its two mushroom cam systems, double security strike plates and activPilot fittings - offers a level of burglary protection equal to solid aluminium windows.

Do not use hard or abrasive materials such as steel wool when cleaning your windows, as their anodised or powder coated surfaces could become damaged and lose their protection against corrosion.

The full Range of Design Possibilities available

Both aluminium and uPVC windows can be easily lacquered in all shades of the RAL colour range, offering enormous customisation potential. The black and white seals typically fit perfectly with any choice of colour. That being said, not only can you choose from a plethora of different shades, but also pick separate designs for the interior and exterior surfaces. This technique allows you to, for example, underline the very modern appearance of the exterior metal surface by choosing a muted shade while simultaneously brightening the uPVC interior using friendly pastels. If you value affordable products with excellent thermal insulation qualities but prefer the traditional look of wood, both sides can also be equipped with wood-grain decor foils.
