FAQ

Because we offer a comprehensive system solution you can rely on. The materials, construction, glazing, installation, and connections are designed to fit together precisely and form a single functional unit. This gives you a solution that makes sense technically and practically, and is designed to function reliably in the long term.

Because MINTAL approaches windows as a comprehensive system solution. Each window is designed based on verified technical data, manufactured from premium components, and installed by their own certified team. The integration of design, production, and installation into one functional unit guarantees long-term functionality, safety, and reliability, confirmed by thousands of implementations in real-world conditions.

MINTAL wood-aluminum windows are made from premium materials designed to work together as a single system. The basis is A500+ wooden beams on the interior and aluminum cladding without visible joints in the corners on the exterior. We use glass from Glassor with an emphasis on thermal comfort, light, and safety, supplemented by Swisspacer spacer frames. The result is a stable, tight, and long-lasting functional window.

Cooperation begins with a request for a quote or a personal meeting. From this moment on, we cover the entire process. We coordinate the solution design, technical details, measurements, production, and installation so that all steps follow one another and function as a single unit. The client has one partner throughout the entire process and clear responsibility for the result. Our cooperation does not end even after installation.

Usually within 48 hours from the moment we have all the necessary documents. The proposal is based on the provided project and serves as a basis for approving the solution and price.

It's not just a list of dimensions. The design includes windows in the context of the building, technical solutions for assemblies, selection of elements according to function, recommendations for details, and system logic, all aimed at minimizing future compromises during construction.

When comparing offers, look at the entire solution, not just the profile or glass. It is important whether the solution has clearly defined and demonstrable technical parameters for the entire window, whether it meets current standards, and whether these values are actually achieved in practice, not just declared in the catalog. Pay attention to how the installation, connections to the building, and responsibility for the result are handled. A quality offer should be based on certified procedures, verified components, and a system that functions as a whole even after years of use. Standards and certificates should not be an exception, but a standard. These are the basis for solutions that work long-term without errors and unpleasant surprises.

Yes. When developing solutions, we work with technical documentation and data that apply to specific assemblies. This allows both the architect and the investor to know what they are working with and why it works.

Each quote contains an exact description and parameters for each item. You need to look for the Uw column. At the same time, each of our offers contains a calculation of the exact total value of all delivered products, which you will find on the last page of the offer.

Installation is an integral part of our system solution. We provide it with our own certified installation team, as correct installation has a fundamental impact on window functionality. It is estimated that up to 70-75% of the window's final efficiency is influenced by the installation and the solution of connection details to the building.

The manufacturer knows the design of the window, its limits, and critical points. In-house installation means uniform technical procedures, clear responsibility for the outcome, and minimal room for errors. It is during installation that it is often decided whether a window will function according to its parameters in the long term, or whether problems will only appear years later.

Even a top-quality window can lose a significant portion of its properties if installed incorrectly. Proper installation is crucial for eliminating thermal bridges, leaks, condensation, and failures in connection details. We perceive installation as a technical process that is as important as the quality of the materials and the construction of the window itself.

Yes. We often cooperate with architects, designers and construction companies to ensure that the windows and their connections are correctly incorporated into the preparatory phase.

Yes. When renovating, correct installation and connection to the existing structure are crucial. Therefore, we design the solution individually according to the actual building.

Yes, but minimally. The aluminum casing on the outside protects the wood from weathering. We recommend regular cleaning of the frames and glass, and, if necessary, adjustment and lubrication of the hardware.

We build long-term reliability on a system. Expert design, verified materials and components, precise manufacturing, assembly according to procedures, and serviceability together form a single functional unit.

The main advantage of wood-aluminium windows is the combination of the best thermal stability, higher indoor comfort, and long-term functionality. Wood naturally insulates the interior, maintaining a higher surface temperature and contributing to a pleasant microclimate. The exterior aluminium simultaneously protects the window from weather influences and reduces maintenance requirements. The result is a more stable solution with a lower risk of condensation, thermal bridges, and functional problems in critical building details.

SLOVENERGOokno is a professional association of Slovak window manufacturers and material suppliers, which brings together companies meeting strict technical, quality and ethical standards in the field of opening structures. It is important for consumers because the members of the association undertake to observe correct technological procedures, standards and transparent information about the real parameters of the products. This way, the customer gains greater certainty of quality, energy efficiency and long-term functionality of their windows.

It is individual depending on the nature of the order. A standard family house has a delivery time of 7 - 12 weeks from the signing of the Contract for Work and payment of the deposit.
