Why not everywhere it is possible to use a sheet of glass

In the market of building materials there is an analog of drywall, but with superior qualities in all respects - of glass sheet.

Look infomercial about this stuff. The material has excellent characteristics not lit, no afraid of water, has a high breaking strength. It is understood that the video advertising and it shows only the pros. Are there any downsides? And they are, because widespread LSU has not received so far.

1. Temperature and humidity expansion LSU.

Although the manufacturer and declares that the material does not absorb moisture, it is under the influence of varying humidity slightly changes its volume. For this reason, sheets, fixedly mounted on the frame - bend or crack (for desiccation). And all of that to them was glued (tile, wallpaper) - also crack or fall off. Examples of people who used LSU and got into this situation - mass.

Here are some of them that I came across on the Internet:

Sheets of plaster in the kitchen without a man just fell off the ceiling. And he had to redo, to do again finish.

Rather, it is spliced ​​sheets closely as plasterboard, i.e. without gaps. A technology for mounting LSU between sheets need to leave gaps of 5-8 mm

I do not know whether these slides readable. You can find them on the Internet

Another example, but the problem of cracking of the material during desiccation or temperature change in geometry

EXAMPLE tile as a crack on the wall of the LSU. Moreover, not at the seams between the tiles, and the tiles crack itself. Those. it turns out that expanding into LSU space, tear material which is glued thereon. In the photos plastered cracked grout.

About such examples can be read on the forums, such as the forumhouse.ru/threads/11703/page-32

How do you know that would prevent such a phenomenon, the seams should be done 5-8 mm and between the sheets need to overwrite the elastic plaster. The walls themselves of LSU need thick plaster cement plaster - to prevent moisture penetration into the structure LSU material.

But this is not the only negative

2. Corrosion of metals in contact with the LSU.

According to information from the author of this picture, such metal corrosion occurred after rainwater dripped from the uncovered facade panels LSU on a metal box. Probably because of LSU distinguished salt that lead to an oxidation reaction.

Similarly corrode profile under SML indoors.

Where it is possible to use the SML? I used it as one of the elements of the thermal protection in the bath, in the place where the sandwich stove pipe chimney passes through the ceiling. Used in conjunction with basalt wool.

Another LSU used in those designs where there are gaps temperature, namely in the panels without rigid fixation screws:

But after reading many reviews about the glass-sheet, used in the decoration of the walls, I would not have it. There is a huge risk of ruin everything, throwing the money spent. Better time-tested plaster or GCR.
