Why wood-aluminum windows

Wood-aluminium windows combine the natural look of wood with the durability of aluminium. They create a pleasant atmosphere indoors, protect the structure from the outside and reduce maintenance requirements. Wood provides excellent insulation properties, while aluminium offers long-term protection and stability. Together, they form a durable and ecological solution suitable for both new builds and renovations, without compromising on design, functionality or lifespan.

For MINTAL wood-aluminium windows, we therefore use carefully selected materials. The base is high-quality multi-layered wood, most often spruce, which stands out for its good insulation properties, flexibility and natural appearance indoors. For maximum energy efficiency, we use top-of-the-line ECLAZ glazing from Saint-Gobain, which lets in more daylight, improves thermal insulation and helps maintain a comfortable indoor climate throughout the year. The exterior aluminium cladding is designed with an emphasis on precise details, clean corners without visible joints, and long-term resistance to weathering.

For people who don't want to take risks

MINTAL wood-aluminium windows are for those who want to have their windows sorted for many years and do not want to return to replacing them. We see standards as a baseline, which we often exceed with our own technical solutions aimed at higher functionality and long-term reliability. We do not just design windows, but a system in which the window, installation and connection to the building function as a single unit.

10 reasons to choose MINTAL windows

1.

Real data, not marketing figures

Every MINTAL window has a CE mark, confirming that it meets European quality and safety requirements. We provide parameters for the entire finished window, not just for the profile or glass, so you know exactly what properties the product you receive will have. We can support all data with technical documentation.

2.

Parameters that work in reality too

Thermal insulation properties, airtightness, watertightness, and wind resistance are verified by tests. The construction is designed to maintain its shape, tightness, and function even after years of use.

3.

A window designed as a single system

We do not treat the window, installation, and connection separately. Everything forms one functional unit that minimizes thermal bridges, increases airtightness, and protects the house structure.

4.

An assembly that determines the outcome

Installation is carried out according to precisely defined technical procedures and system solutions. Every detail of the installation has its significance, and every project undergoes a check of critical points that determine the tightness, functionality, and long-term reliability of the windows.

5.

Transparency without hidden compromises

You know exactly what the solution contains and why it is designed the way it is. The materials, fittings and installation are clearly defined and comparable point by point.

Up to 75% of a window's functionality depends on proper installation

For wood-aluminium windows, it's not just the product itself that matters, but the entire system of design, preparation, and installation.

At MINTAL, we address quality as early as the project phase. As designers, we can identify critical details and future risks from the documentation even before installation begins, ensuring that problems do not arise on-site.

The installation itself is carried out by our own team according to precise technical procedures, with emphasis on proper connection of the window to the building structure and control of details crucial for airtightness, functionality, and long-term reliability.

Frequently asked questions

Why choose MINTAL wood-aluminium windows?

Wood-aluminium windows combine the natural comfort of wood in the interior with durable aluminium cladding on the exterior. This results in a stable construction, high energy efficiency, and long-term functionality without unnecessary compromises. This is a solution designed for homes where comfort, architecture, and longevity are key factors.

How long do wood-aluminum windows last?

With proper design, installation, and regular maintenance, wood-aluminum windows are designed for decades of use. The external aluminum cladding protects the wood from weather conditions, significantly extending the lifespan of the entire structure.

Does wood in interiors need to be maintained?

Wood in the interior has a finish designed for long-term use. Routine maintenance mainly consists of cleaning and checking the surface layer. Regular renovation is not required as with exterior wooden elements.

Will the windows not fog up or freeze?

Condensation and thermal bridges most frequently arise due to incorrect design or installation. We design MINTAL timber-aluminium windows as a system, including installation and connection to the building, thereby minimising the risk of condensation and problems in critical details.

What about installation? Does it really make such a big difference?

Yes. Installation has a fundamental impact on the functionality of the window. Even a high-quality window can fail if installed incorrectly. Therefore, installation is carried out by MINTAL's own certified team according to precise technical procedures and critical point checks.

Are timber-aluminium windows also suitable for modern large glazing?

Yes. The laminated timber construction ensures high stability even with large dimensions. Wood-aluminum solutions are also suitable for modern architectural projects with large glazed areas.
