At KNS we strive for perfection every day and invest in the most modern machinery, whose precise operation delivers the highest quality joinery. The combination of V-Perfect technology and the use of the best PVC profiles results in perfectly crafted window corners that meet the highest standards in terms of design, technology and durability. Thanks to V-PERFECT technology, we achieve an exceptional effect in window corner joints that cannot be achieved with any other method - 100% aesthetic while increasing strength by 20%!

• - Unrivalled aesthetics: no material excess, well-finished corners that retain their appearance over time, unlike traditional methods;
• Increased watertightness: a flexible and precise seal, which significantly improves the window's watertightness;
• High durability: the reinforced weld surface makes corners more resistant to mechanical stress and damage compared to traditional methods;
• No unnecessary processing: no additional operations after welding, such as painting or cleaning corners, which are necessary with traditional methods;
• Ease of maintenance: smooth surfaces are easier to maintain.
