Three years ago, there was a need to put windows in a living room, so I naturally looked closely at inexpensive profiles. I stopped my choice on the Proplex windows, the price is acceptable, the quality reviews are pretty good, and a large selection of PVC profiles allows you to choose the best one. I chose one of the cheapest options, the profile is three-chamber, white, the surface is flat, semi-gloss.
Well, after three years, you can summarize some of the results. The windows, as during installation, remained white, did not fade, did not turn yellow, due to the semi-gloss surface, scuffs and small scratches were almost not noticeable. In winter conditions, when the temperature reached -30 ° C the windows did not freeze, there was almost no condensate, the profile did not lead, as is often the case with other cheap brands of profiles.
Soon I am going to change the windows in the apartment, I will definitely make a choice in favor of the inexpensive Proplex profile.
pros
Budget price, decent quality, excellent performance in the winter.
Minuses
Given the cost - I do not find any cons.
