If you are planning to buy windows, you have certainly noticed that prices can vary significantly. Sometimes the same number of windows in different offers costs even a few dozen percent more or less. Where do these differences come from? Are cheaper windows of lower quality? Do more expensive ones mean a better investment? In this article, we will dispel your doubts and explain in detail what determines the price of windows.

Price differences between aluminum, wooden and PVC windows

The first aspect that influences price of windows, is the material they are made of. There are three main types of windows available on the market:

PVC windows

The cheapest solution on the market, popular in residential construction.
Light, easy to install and relatively good thermal insulation.
They may have different profile classes, which affects the price (standard vs. premium).

Wooden windows

More expensive than PVC, but offers a natural look and good insulation.
They require regular maintenance and are less resistant to weather conditions.
High-quality wood (e.g. oak) increases the price compared to pine or spruce.

Aluminum windows

The most expensive of the three types, but they offer exceptional durability and a modern look.
Perfect for large glazing and energy-efficient buildings.
High weather resistance and possibility of thin profiles.

Aluminum profile systems – a key factor influencing the price

The basic factor deciding about price of aluminum windows a profile system is used. There are many system providers available on the market, such as Aluprof, Aluron, Reynaers, Schüco or Ponzio. Each of these companies offers different solutions that differ in many respects:

Thickness and construction of profiles

The thickness of the walls of aluminum profiles affects both the durability and price of windows. Premium systems use thicker walls and additional stiffening (e.g. reinforcing feathers), which increases the cost, but also improves the window's resistance to mechanical loads or changing weather conditions.

Thermal insulation of profiles

Aluminum systems use thermal breaks to reduce heat loss. Cheaper systems often have thinner breaks or are made from less advanced materials, which results in poorer thermal insulation.

Manufacturer Pricing Strategy

System companies have different pricing policies – some aim at the premium market (e.g. Aluprof, Schüco), others offer more affordable solutions (e.g. Ponzio or Aluron). Even if the profiles are technically comparable, their price may vary due to brand positioning.

Fittings – the mechanism of window operation and their cost

Fittings are a key element influencing the functionality of a window. Standard windows may have basic tilt-and-turn fittings, but the offer also includes more advanced solutions, such as:

Burglar-proof fittings (class RC2, RC3)
Hidden hinges (aesthetics and easier maintenance)
Automatic control (e.g. intelligent locking systems)

The more advanced the fittings, the higher the price of the window.

Glazing type – significant impact on price

The glass in aluminum windows can be as much as half of their value. The price is influenced by:

Number of chambers (two-chamber, three-glass)
Type of gas filling the spaces between the panes (argon, krypton)
Low emission coatings improving thermal insulation
Tempered glass, safe, sun protection

Type of window base used

The window base, i.e. the mounting element separating the window from the ground, also affects the price. Depending on the material and technology used, it can:

Improve thermal insulation and eliminate thermal bridges.
Stabilize the structure and facilitate assembly.
Be made of various materials, such as XPS, PUR or aerated concrete, which affects the costs.

Additional equipment and personalization

Companies offering aluminum windows give customers the option of personalization. You can choose from different colors (powder coating, anodizing), types of seals, as well as additional elements such as external roller shutters, mosquito nets or automatic control.

Each modification incurs an additional cost, so offers may vary significantly depending on the options you choose.

Where do we buy windows? Manufacturer's brand and factory location

The place of production is also important. Renowned manufacturers apply more stringent quality standards, but their windows are more expensive. Local companies may offer cheaper products, but they do not always match the quality of branded solutions.

Assembly service – a hidden cost or a key element?

It should not be forgotten that differences in prices also result from installation costs. Companies use different installation techniques (e.g. warm installation), which can increase the price, but also affect the energy efficiency of the window.

Summary – how to choose the best offer?

When analyzing offers, it is worth paying attention to details, and not just being guided by price. The cheapest offer may mean lower quality profiles, less durable fittings or weaker thermal insulation, which in the long run means higher heating bills. A more expensive offer may be more profitable if it takes into account better utility parameters and a longer lifespan of windows.
