I ordered this door in the "door factory" in the summer. The price tag for 35 thousand rubles with installation. When configured in a store on the street. Nakhimova, a girl, the seller answered my question about locks knowingly that they only put locks not with flat keys, like they freeze, but locks with keys like Pinocchio's (with big keys). I hesitated but for some reason I got this information. This key subsequently tore all my pockets, and today in the first frost of November (-13) I found that not only was the lock covered in a chicken, but my mother didn’t feel cold from the siphon hole. Although I did not plan to arrange ventilation through the castle, but thanks to the Falk people they do not give suffocation. I also found that the narthex of the door around the perimeter to the other is 10-15 percent of the perimeter. And this is just the beginning. Winter is ahead.
Now about the measurement and installation. I experienced this with humor in the summer, as I am not a conflict person, and hoped that I would put an expensive but warm door into my house. But since it turned out to be expensive and not warm, as I had dreamed of before today's frost, it was like this, the arrived measurer measured the doorway and said with care that my threshold in the opening plus the threshold of the door itself gives a total threshold of decent height, but we all know that in Russia, two troubles of roads and thresholds and his proposal to cut my threshold to the height of the threshold of the box, I took positively, although he warned me that this was an additional cost.
He wanted the best, but apparently forgot to add the future size of the cut-off threshold to the size of the future door, since he came to measure with his wife and children and they constantly pulled him out of the car, and when I arrived at the store without calculating all the risks, I signed in the measuring sheet and agreed and with the size of the door and with the cutting of the threshold in the opening. The arrivals of the World of Doors (I realized that this was one gang with the Factory of Doors) on the appointed day tore off my old door (which, as I understand it, was no worse than the new one, also worked actively for inflow) cut down the threshold in the opening clearly by the technical assignment and inserting a new box into the opening, they began to actively anchor it, not paying attention to the fact that the box’s panel does not close the gap from the top of the opening.
To my question about the gap, they cheerfully replied that I Pinocchio with a wooden head signed the act of measurement and now get the door with a hole on top and a shiny key that tore all my pockets.True, before leaving, they took pity on me and gave me the poor fellow some useful, and most importantly free tips on how to close the gap from above.
It was in the summer, but today in the first frost (-13) everything was still freezing. That's the kind of door I got from FAL and Co. Probably have to hang a felt canvas with a drawn hearth.
pros
The door works as forced ventilation to the house.
Minuses
No recuperation system (preheating of air in the supply)
