They say that the support profile is the weakest point in a plastic window. I was clearly convinced of this.

Double glazed windows, thick frame, energy-saving glass with spraying. And all this can come to naught if you forget about such a thing as a stand profile, which can ruin everything.

Well, do-it-yourself window installation continues. After I discovered that there was no metal reinforcement in my smallest window, I began to carefully study all the details on my plastic windows (how it was,read here)

And the support profile attracted a lot of attention.

The appearance did not inspire confidence at all. In addition to being thinner than the frame itself, the plastic itself is very thin and fragile.

Thanks for the blowing protection though.

At first, I could not understand why there was this "rope" made of polyethylene foam. Then I found out that it prevents blowing of the support profile at the point of abutment to the frame. Not all factories put it on ...

And the most important thing is that you will not leave the window without final finishing for the winter.

If you foam everything, hiding the support profile, then you will not put any ebb tides outside, nor a window sill inside.

So you have to leave it that way.

And in winter it is a guaranteed freezing point. And even ten layers of glass will not protect. Therefore, finishing with insulation is simply necessary. This year you need to keep up ...
