Reinforce The Best Leadlight Windows For The Best Results

PropertyfindsAsia.com | Reinforce The Best Leadlight Windows For The Best Results | How to reinforce a leadlight window is a crucial aspect to be known by those individuals who work with the leadlight windows, the craftspersons. In order to prevent bowing & sagging over the years, windows which exceed 4 square feet in total dimension need to be as stable as possible. The requirement of stabilizing the window depends on the design & where the window is supposed to be installed. 

The constant opening, as well as closing of a door, will make a leadlight glass window bow if it is not being properly stabilized. Therefore, any window, no matter whatever be the size, that is going in a door, including the cupboards, needs to be reinforced for sure. The same goes for a window which is installed as an exterior window and is exposed to several outside elements, especially wind, or near a door that is opened & closed frequently. 

In order to determine the actual square footage of a window pattern, you need to multiply the width times the height, in inches, then it is to be divided by 144. In order to convert metric to square feet, you need to multiply the width by height in centimeters and then it is to be divided by 930.25. 

When it is stated “depends on the design”, I am talking about the straight lines which make hinge joints. A hinge joint is either a fully straight or straight line which allows the window to fold in half. You will certainly find those straight lines in geometric designs, but they can appear in any design. If the lines do not go all the way across the window, this might go far enough that thus could not only fold but break any glass which gets in its way. The folding can occur at any point of time the window is not lying flat on the work surface. This is not fun seeing your finished window fold in half, pulling the glass out of the foil or lead and perhaps breaking some glass in the process.

So, what can you use to reinforce the leadlight windows? This is called copper restripe & this works with both lead and copper foil. Copper restrip is prepared by several manufacturers. 

The restrip will bend & follow curves very easily as you are using it, but this does not bend on edge. In other words, you would hold a piece in your hands inwards. This will not budge. If you hold this with some flat surface facing up, you can bend this with much ease. 

While opting to use restripe for reinforcement, it is crucial to keep this in mind that it must run from one edge of the window to the other. This can go with any vertical or horizontal, or both if required. When this goes both ways, one amongst the pieces of restrip will need to be cut where this intersects with the other. Then this will restart on the other side of the intersection. In other words, it can be concluded that these 2 pieces will form a cross where they would meet. Once this panel is soldered, the vertical and horizontal pieces will be joined together from the soldier which runs through the lead joint or copper foil seam. This is nothing very special you will have to do in order to make this happen. This is a natural occurrence which runs when you solder. 


Copper restrip for reinforcing the leadlight windows can be bought at the majority of the leadlight glass suppliers.
