The corners are where a uPVC frame is made or broken. Here's how we weld strong, sealed corners.
uPVC frame corners are fusion-welded — the profile ends are heated and fused into a single, continuous, sealed joint. A well-welded corner is strong and watertight; a poor one is a weak point that can leak or crack.
We weld corners carefully as part of in-house fabrication, so the frames we build are strong and sealed at the joints — the foundation of a window that lasts.
They're fusion-welded — the profile ends are heated and fused into a single continuous sealed joint, which is strong and watertight.
Corners are the frame's weak point if done poorly. Good welding gives strong, sealed, long-lasting joints.
Yes — corner welding is part of our in-house fabrication at Pannimadai.
