The first time I met the OSB plywood in 2002, when expensive Australian equipment brought to the company. In addition to the standard label, the machines were closed with large sheets of strange material. All installers crowded around wonderful boxes, considered sheets, stroked the lacquered surface of plywood.
In the first he was right, and at the expense of the fire was wrong — the men from the night shift found Phaneur in the departures in the backyard, they shone through the fence and cleared into the gardens.
Exactly 10 years later, in 2012, the first Russian OSB plant opened in Kirov. Thus began a victorious procession of a chipstate sheet in Russia. Light, durable, not afraid of water, mold, insects — just the dream of a builder. It is not wonderful that OSB quickly won popularity — now there is not a single building without anyone.
Three years ago, OSB-3 was very high in price. The price in the markets of the city reached 720 rubles. I just had the insulation of the attic and, having considered it in which the use of such plywood will fall out, I refused its use. But with the attic, too, did not succeed, first I got off with insulation, then it was not trite to it — all the strength and money went to the workshop. This year, it was decided to finish and shelter the frame rack outside OSB.
In solid confidence that the price of Faneru has reached cosmic heights, I went to the market. Pepple! And the price is, on the contrary, decreased.
475 rubles per sheet of production Kronospane!
How so? For three years, the same insulation went up by almost 50%, the mounting foam is 100%, brick, metal, self-tapping screw … everything rose in price. And plywood fell.
What is explained by the attraction of unprecedented generosity?
Everything is very simple. In the attic I lay 10 sheets of plywood, which I bought four years ago. Compare them with just purchased. The difference immediately rushed into the eyes. The new plywood is not only easier, it is in its structure much loose.
Compare the second and third photos. The difference is very clearly visible, there is no need to get closer to the picture. The manufacturer not only saved on the chips, but also began to add a much less binder — wax and glue. And this savings thoroughly affected the quality of the material. Only a few manufacturers did not allow themselves to worsen the quality of the sheet.
I noticed if earlier it was possible to hurt the corner of plywood about the plasterboard wall and get a decent dent, now even gypsum remains a whole, but the plywood sheet has a corner. In the «old» sheet of plywood, the Self-timeline was entered with difficulty, the hat was screwed up to the end — lacked the power of my screwdriver. But, in the «new» sheets, hitting in a loose place of the self-suite hat can be traded through. Yes, what to say, if the corner of the sheet can not be very strained with his hands.
It turns out that reducing the price, the manufacturer strongly «dropped» quality. But from this plywood makes skew houses, some do not even put bodies, hoping for the stiffness of the sheet. But it turns out, it is practically no.
