The windows are made in Russia, normal. The installation is clumsy - there is a void under the window sills, foamed from the inside. The openings are not plastered on the outside, but slightly covered over. The door began to jam after a couple of weeks, they offered to hire someone or fix it themselves. That's how it opened if you pressed it with your knee. A few months later, the door almost fell off its hinge. I couldn't get through to the director, he doesn't pick up the phone, and he "doesn't see" the SMS. So if you want to carry, repair and redo yourself for your money, then this company is for you.
