Any wooden door must have:
1. Seals.
2. Thresholds.
3. Box.
4. Drill mechanism.
5. Necessary accessories.
6. Door eye.
7. Aciling structure.
8. Well, of course, the door itself.
Modern wooden doors today can be divided into three main groups:
1. Shield doors with insulation at their own metal sheets.
2. Filenced massive doors having a massive strapping.
3. Shield doors with insulation.
To date, the most demand among buyers are thyroid doors, with a heater, which are based on metal sheets. If we compare the usual massive doors, which over time, under the influence of weather, change their shape, begin to close poorly to make a different noise, this design of the doors is not capable of this.
The outer side of any door should have a beautiful view, and should also be covered without fail with protective varnish. Naturally, the better the varnish, the longer the wooden door, but the metal doors are much more reliable.
By installing an additional visor above the door, you can avoid negative nature factors that will affect the door structure.
