What should I take into account when ordering a glass table top?
There are different types of applications and situations for which you are looking for a glass tabletop. We make a distinction between a top that is only for the protection of an existing table top and a glass top that is only supported at a few points or all around and the glass top is the actual table top. In addition, you naturally have glass tops for interior applications and tops for outdoor applications. But actually this makes little difference. We recommend making all tops from tempered glass.
Why ALWAYS tempered glass for a tabletop?
A table top must be strong and safe. Tempered glass is 4 to 5 times stronger than untempered glass. Of course you can get more strength by choosing an unhardened blade of 12 or 15 mm, but we do not think this is wise. Normal/untempered glass is sensitive to thermal shock. By this we mean that this glass cannot withstand higher temperature differences. Untempered glass can absorb a maximum of 30-40 degrees of temperature difference. This also applies to partial heating, whereby part of the leaf therefore has to endure a temperature difference of approximately 30-40 degrees. Now you will think: "I have nothing to do with that". But remember that when you put a glass of hot tea or coffee on the glass top, it can quickly heat up in a small area, so that a difference in temperature of the glass top can indeed occur in a short time. The place where the cup of tea is placed heats up, 5 cm next to it the leaf will remain cold. And that can cause glass breakage.
Tempered glass can withstand temperature shocks of about 200 degrees. A cup of hot tea is no problem at all. But this also applies to partial heating of the glass by the sun. If a table is in the blazing sun, the glass is also heated. If one part of the table is in the sun and another part in the shade, it could also lead to glass breakage with normal glass in extreme cases. With tempered glass, how not to worry about that.
Which size do I need?
We advise you to carefully measure the table size yourself and not to rely on the brochure or what the manufacturer/supplier has described as the size. In practice there is always a deviation. And it is annoying if your ordered sheet does not fit nicely.
Which thickness do I choose?
This completely depends on the size and the purpose for which you will use the blade. If it is for protection then often 5, 6 or 8 thickness is sufficient. If it concerns a table where you need a full glass top that is only supported on the corners or edges, you quickly go to 10 or 12 mm thickness, sometimes even 15 mm. There are no standard tables for this, that is a matter of feeling. We can help you with that if you can't figure it out.
What do I do with the edges?
You will always have to have the edges poly-sanded. This finish ensures that the edges are neatly finished.
Why should I round the corners?
Even if the edges are poly ground, we advise you to always round the corners. Even if it is with a radius of only 2 mm. As a result, the corners are rounded and you won't get stuck behind them with your pants, shirt or dress. If the corners are not rounded, they are a bit sharp and there is a good chance that you will get caught behind them with your clothes and can tear them apart.
That's going to be expensive!?
A leaf is often ordered to protect a beautiful (often wooden) table top. If you want to protect your beautiful table, you want to do it in a good and practical way. And you don't want to think afterwards: "I wish I had spent 20 euros more for the rounded corners". Or "I wish I had chosen tempered glass, now I can't put a cup of tea on it". Also realize that you have a custom glass top made in a factory to your specified size. This is not possible for a few tenners, after all it concerns 1 separate sheet where set-up costs, processing costs and transport are relatively expensive compared to a series of, for example, 100 identical sheets.
And of course you can save money by choosing a thin sheet, untempered glass, without rounded corners. But do you realize that this is not wise. You would like to have a magazine that you can enjoy for years and that helps you fulfill your wishes. Then it really is better to spend a few tenners more and do it right, than to save yourself some money now and then be annoyed by the restrictions for years to come. If you linger once behind an unrounded corner of the magazine and you pull a tear in your expensive jeans or dress, you will be disappointed that you have cut back on that.
