    ARTICLE NO.120 | Corner Codes: The Small Component That Holds Your Window Together

    A window frame is not a single piece of material. Whether made of aluminum, UPVC, or steel, the frame is assembled from multiple lengths of profile cut at precise angles and joined at the corners. The strength of those corners determines the strength of the entire window. And at the heart of every strong corner is a small, often overlooked component: the corner code, also known as the corner bracket or corner connector.

    ARTICLE NO.119 | Two-Bar and Four-Bar Hinges: Understanding the Difference

    Not all hinges are created equal. For casement windows, awning windows, and certain types of projected windows, the hinge mechanism determines not only how smoothly the window operates but also how well it seals, how securely it locks, and how long it will last. Two common hinge types dominate this category: the two-bar hinge​ and the four-bar hinge. While they may look similar at a glance, their differences in design, performance, and application are substantial.
