By choosing aluminium patio doors, you're investing in a solution that redefines luxury and functionality.

Resilience

Built to Last Generations: A 45-Year Aluminium Investment

Want to forget about replacing doors for the rest of your life? The lifespan of aluminium folding doors reaches up to 45 years, significantly exceeding the durability of PVC (25-35 years) and timber (20-30 years). Aluminium doesn't corrode, warp or swell from moisture or extreme temperatures. This unchanging dimensional stability means your doors will operate smoothly and quietly for decades, maintaining perfect sealing and aesthetics without costly repairs.

Energy Efficiency

Energy Efficiency: Thermal Comfort and Lower Bills

Imagine a winter evening. Frost outside, yet you're enjoying pleasant warmth throughout your living room, without unpleasant cold radiating from the glass. Modern, thermally efficient aluminium folding doors, thanks to profiles with thermal breaks, achieve an excellent U-value from 0.9 W/(m²K). This means real heating savings of up to 25% annually and unmatched year-round living comfort.

Safety

RC-Class Security: Peace of Mind for Your Family

Need absolute certainty that your home is a secure fortress? Our aluminium folding doors can achieve burglar resistance class RC3 (according to PN-EN 1627 standard), effectively protecting against forced entry attempts using tools like crowbars. Multi-point locks, P4 safety glass and concealed hardware create a fortress protecting your peace of mind – a security level unattainable with standard systems. Moreover, having certified doors of this class may qualify you for home insurance discounts.

Minimal Maintenance: Save Time and Money

Don't have time for annual labor-intensive maintenance? Aluminum folding doors require only 2-3 hours of attention per year - 85% less than wood. Gentle washing and periodic lubrication of the mechanisms is enough. No need for cyclical varnishing or crack repairs is a real saving of 15-20 thousand zlotys over 30 years. That's time and money you can spend on your passions.
