Aluminium and PVC windows - what's the difference?

Everyone who builds a house and buys windows faces this decision: whether to choose aluminium windows or go for PVC. We present them below!

PVC windows are well-known and by far the most popular solution among Polish investors. Aluminium windows, on the other hand, have gained many supporters in recent seasons, tempted by their minimalist design and great possibilities to match the architectural vision.

Which window to choose: aluminium or PVC? Compare their advantages and disadvantages!

PVC windows - the biggest advantages

What makes PVC windows stand out?

Aesthetics: When using the Elegant profile, which combines the characteristics of PVC and the appearance of aluminium, you can achieve an elegant and modern window design that blends perfectly with different types of buildings.

Ease of maintenance: PVC is a material that is easy to clean and maintain. Simply wipe the windows regularly with a damp cloth and mild detergent to keep them clean. They do not require painting or special preservatives, which makes it even easier to keep them in good condition

Thermal insulation: PVC windows are known for their excellent insulating properties. PVC is a low heat conductive material, which means that it provides excellent protection against heat loss.

Noise resistance: PVC windows are also a good sound barrier. Thanks to their structure, they absorb sounds from outside, which contributes to acoustic comfort inside the building.

PVC is also insensitive to rust and is not deformed by moisture. As a result, PVC windows retain their properties for many years, which translates into their durability and long-lasting use.

When will PVC windows not work?

Although PVC window construction has many advantages, there are some situations where it is not recommended or may not be the optimal solution. Here are a few such cases:

PVC windows have some limitations in terms of size, especially when it comes to large, panoramic glazing. Due to the structure and strength of PVC, larger windows may require additional structural reinforcement, which can increase costs and limit available design options.

Windows using this material are very airtight. This can hardly be considered a disadvantage, but it is worth bearing in mind adequate air circulation.

They are also not the best choice for buildings with high exposure to fire. PVC is a combustible material, so PVC windows are not recommended in areas where there is a high risk of contact with fire.

Aluminium windows - the greatest advantages of aluminium constructions

Aluminium windows are becoming increasingly popular, especially in loft and minimalist architectural projects and premium developments. They look elegant and have very good energy efficiency and durability, although, as with PVC windows, a great deal depends on the production technology.

Here's why you should choose aluminium windows!

  • High energy efficiency: Traditionally, aluminium has been regarded as a material with poor thermal insulation. However, thanks to advances in technology, it is possible to use so-called 'warm aluminium'. This involves the introduction of thermal breaks that effectively insulate the window frames, reducing thermal bridges and improving energy efficiency.
  • Fire resistance: Aluminium is a non-combustible material and does not emit toxic gases when exposed to high temperatures. This is why aluminium windows are often used in buildings with high fire protection requirements. High resistance to moisture and other atmospheric agents: aluminium windows are highly resistant to rain or snow. This is due to the anodised aluminium, which is not susceptible to corrosion.
  • High rigidity of aluminium windows: this advantage of aluminium construction makes the windows suitable for creating areas of very large glazing. Huge, panoramic windows, several-metre-high glazed walls popular in modern barn-type houses, but also in office buildings - these are usually the result of construction using aluminium constructions.

When will aluminium windows not work?

Like any solution, aluminium constructions also have their limitations. Compared to PVC windows, aluminium may seem more expensive. This is due to the global price of aluminium,. However, the cost is fully rewarded by their increased resistance to harsh conditions.

Architectural style: some architectural designs may prefer other materials that better reflect the desired style and aesthetic. For example, if a traditional, natural look is sought, wood may be a more appropriate choice.

It is worth noting that the choice of material for window depends on individual preferences, the needs of the building and other factors such as local regulations and budget. It's worth consulting a window expert who can help you match the right solution to your specific needs.
