Frequently Asked Questions

• Explanations (Terms Used in Product Descriptions)

Uf – Thermal transmittance of the frame. A lower value indicates better insulation;

Ug – Thermal transmittance of the glass. (Triple glazing usually provides superior insulation);

Uw – Total window thermal transmittance. (This value includes both the frame and the glass);

Rw – Sound reduction index. A higher value represents better noise reduction;

RC Class – Burglar resistance. A higher class (higher number) ensures a higher level of security;

• Which aluminum system is the most expensive or the most affordable?

The price of aluminum products depends on the supplier you choose and the specific system that fits your needs.

1. The German Schüco systems are the most premium and, therefore, have the highest price point.
2. The Belgian Reynaers and Polish Aluprof systems are priced similarly to each other, but are more affordable than Schüco.
3. Spanish Cortizo systems are the most budget-friendly option.

Please note that steel products are generally more expensive than aluminum ones.

• What affects pricing?

Since we manufacture aluminum windows, doors, and facades exclusively tailored to your needs, every project is unique. Pricing depends on your building’s design, the chosen aluminum system, security requirements, glass types, fire safety standards, and other technical specifications.

Therefore, we provide a final price only after a detailed engineering calculation. Once completed, a comprehensive estimate will be sent directly to your email.

• How long does it take from order to installation? 

It depends on your project specifications and choices, typically ranging from 5 to 10 weeks.

(Lead times are influenced by: your choice of color and finish, the popularity and availability of the selected system, specific hardware and accessories, current stock levels at our aluminum suppliers.)

For a more precise timeline for your project, we recommend contacting us for a consultation.

• When do we choose to use safer, high-quality glass?

We always use safety glass (tempered or laminated) in these cases:

• Large windows or doors (2.8m2 and above);
• Floor-to-ceiling glass (windows or doors reaching the ground);
• Areas with high wind or environmental pressure;
• When it is required by your architectural plan;

While this can be slightly more expensive, it ensures your home remains safe and durable.
