FAQ
WHAT IS THE RIGHT CHOICE OF GLASS WHEN THERE IS WEIGHT ON IT (E.G FLOOR, SHELVES)?
There isn’t any right option. It only depends on the size of the glass, the use and the way that will be leaned on. The more frequent option is triplex glasses with multiple membranes of pvb, of great thickness and thermally hardened (tempered \ securit).
WHAT IS THE WEIGHT OF THE GLASS?
- 2mm- 5,0 kgr
- 3mm- 7,5 kgr
- 4mm- 10,0 kgr
- 5mm- 12,5 kgr
- 6mm- 15,0 kgr
- 8mm- 20,0 kgr
- 10mm- 25,0 kgr
- 12mm- 30,0 kgr
- 15mm- 37,5 kgr
- 19mm- 47,5 kgr
The above indications are calculated per square meter , ie
A square meter glass ( 1m X 1m ) of 2mm weighs 5,0 kgr .
WHAT KIND OF GLASSES CAN BE THERMALLY IMPROVED (TEMPERED \ SECURIT) AND HOW THIS PROCESS WILL HELP. WHAT KIND OF GLASSES CAN BE TRANSFORMED INTO TRIPLEX (LAMINATED)?
The thermally hardened glasses (tempered \ securit) have the following properties:
- - The resistance to shock, vibration, high temperatures and pressures is greatly improved.
- - If a thermally- hardened glass breaks, it crashes into very small grains of 5mm, therefore we avoid the slightest injury which might have occurred if the glasses were simple (float).
All types of glass can be thermally hardened except from the following ones:
- - Mirrors
- - Fire resistant
- - Soft coating
- - Triplex
All kinds of glasses can be transformed into triplex (laminated) can except from the following ones:
- - Bas relief
- - Sandblasted (Mat)
DOES THE GLASS BREAK ON ITS OWN ?
NEVER! Many times we have seen glasses to break, “on their own”, a fact that is not true, as the most frequent reason is that the glass has suffered from a thermal shock. When the glass and particularly a colored one is exposed to the sun, it develops very high temperatures. If there is an object such as a sign, a tree or other external element which covers part of the glass an uneven heat distribution occurs on its surface and the glass breaks. To avoid this phenomenon, the best solution is to make our glass securit (thermally hardened) so as the protection to a thermal shock is almost absolute. Also we can transform it into Rhodes glass and we minimize it by 20-25 %
I PLACED AN ADDITIONAL LOCK AT THE ALUMINUM DOORJAMBS, IS THAT SAFE?
Many times, a lot of people place additional locking systems and locks and they spend much money on them, leaving common glasses with great thickness that have no security. It is very likely that a burglar who tries to enter a house / a country house/ shop will not deal with all these locks but may break the glass and will enter easily in it. It is a very common thing in burglaries that many of us do not take into consideration. What we can do, is to use triplex glasses which start with small thicknesses (e.g 3 +3 mm) which will give us a very good result. Also combining them with energy glasses we may amortized all these money we spent in just few years.
IS THERE A GLASS THAT YOU CAN SEE THROUGH BUT NOT TO BE SEEN?
All glasses have a small reflection even the ones that are completely glazed due to the fact that the light falls on them. This is how the reflective glasses work like the curtain walls that large buildings have. There are glasses that reach 66% of reflectance but they also work with the aid of the light. When in the inner side of the glass as we have less light, as during the daytime, we cannot be seen, but when we have more light on the inner side of the glass, as overnight, then someone can easily see us clearly.
WHAT CAN I DO TO IMPROVE THE SOUNDPROOFING OF MY GLASSES?
The problem of soundproofing, especially in big cities or crowded places, is a very frequent phenomenon. The solutions that we have are the following.
- - To install and use double glasses instead of single ones and with a difference of thicknesses in the two glasses, for example a standard double glass consists of two glasses of five millimeters (5mm +5 mm) while the right solution is 4mm +5 mm or 5mm +6 mm.
- - To use double glasses with triplex glasses along with an acoustic membrane for best results.
- - Also the higher the thickness of the glass the better the soundproofing that is providing.
WHAT CAN I DO TO IMPROVE THE INSULATION OF MY GLASSES?
There are 3 ways to improve the insulation of the glasses of a house - shop etc.:
- 1. To place energy glasses, that in relation to the common glasses can reduce the U valeu up to 55%.
- 2. To increase the gap of the double glass and therefore we can have a better U valeu for every 2mm. A sufficient gap is 16mm.
- 3. To use a noble gas such as argon instead of room air for the gap of the double glass. In this way we can reduce the U-valeu up to 17-20%.
