The neighbors put up windows, I saw the work and I really liked it. I ordered it for myself there .I was satisfied with both the price and the quality !The guys did well professionally and on time, they installed and also smeared the outer slope with cement so that the foam would not stick out.The window sill was also laid on cement.(before that, I put it in another company - they didn't even offer such a service, over time the foam crumbled.) I took an action and put an energy-saving window.I'm very happy, I'm happy with everything.
