Frequently Asked Questions
Q1: What are the main advantages of aluminum folding windows?
Aluminum folding windows offer 100% opening space, providing maximum ventilation and unobstructed panoramic views. They are space-saving, durable, and highly resistant to corrosion compared to other materials.
Q2: Can these windows help with energy efficiency?
Yes. Our windows use thermal break aluminum frames and double or triple glazed tempered glass. This significantly reduces heat transfer, helping to maintain indoor temperatures and lower energy costs.
Q3: Are the windows soundproof?
Our standard double glazing provides sound insulation of at least 32 dB. We also offer acoustic glass options that can increase sound reduction up to 40 dB for high-noise environments.
Q4: How do they perform in extreme weather conditions?
They are designed with EPDM weatherstripping and multi-chamber seals for excellent air and water tightness. They have been tested for wind load resistance up to 3000 Pa, making them suitable for coastal areas.
Q5: Can I customize the color and size of the window?
Absolutely. We offer a wide range of RAL powder coating colors, anodized finishes, and wood grain transfers. Panel sizes and the number of panels (from 2 up to 8) can be fully customized to fit your architectural needs.
Q6: Is the folding mechanism easy to operate?
Yes, our systems use heavy-duty stainless steel hinges and multi-wheel rollers, ensuring smooth and silent operation. The hardware is tested for over 20,000 opening and closing cycles.
