Secrets

There are people selling vinyl windows (replacement and new) that claim they are all welded units. Some of these people are not saying they are not. How can you tell? When you look at the mitre joint on the sash it will have a vinyl cement to cover the gap of they mitre. Look at the edge of the sash and you see a screw near they edge you will see that it is screwed together to look like a welded sash. The sash has to be assembled with the glass at the same time. A "TRUE" welded vinyl sash will have a glass bead around the perimter of the sash on the outside or inside to secure the glass in place with either double face tape or silicone. (The outside bead is my preference)
