Not so long ago I decided to change a couple of windows in the apartment, I turned to one of the many companies, offered a Richmond profile, citing low cost and good quality. I heard little about this profile, so naturally I began to look for information, study reviews, it seems I did not find anything negative. I agreed.
And after about a week they put me windows. I looked and was horrified! There are huge gaps between the glazing beads, the air blows from them, already whistles, some welded seams at the frame joints, the edges of the window sill are very short. He talked with a representative of the company, cannot explain anything sensible, he says that no windows have complete tightness. I agree, but not to the same extent!
Of course, I can’t say that Richmond’s poor-quality profile cannot be blamed, maybe it’s all who made the window, but I’ll not risk ordering windows from this profile for the second time, despite its rather low cost.
Minuses
In my personal example - very low quality.
