Warm windows are twice as expensive as simple double-glazed windows, because of the equipment, processing technology of window structures. How to explain to the buyer that the windows will pay off the investment over time? There are many myths told by unknowing customers, as a result, people refuse to buy energy-saving windows. This article will dispel myths.
The difference between outside and inside
PVC profiles of German companies Rehau and KBE, as well as domestic Novotex are the best in terms of heat transfer resistance. It is known that the larger the profile width and the number of chambers, the warmer the glazing.
Learn how to choose the right profile to keep windows warm in our video tutorial.
Lumber profiles can be an alternative to polyvinyl chloride. The most popular types of wood are pine, larch and oak.
Wanting to order truly energy efficient glazing, the customer is faced with a choice - wood or plastic? Which one is better?
Due to its low thermal conductivity, wood is resistant to sudden temperature changes, and in combination with an energy-efficient glass unit and a good seal, a properly processed wood profile is much warmer than any plastic one. However, such material requires good care and special treatment every five years.
High-quality PVC window constructions will cost significantly less than those made of wood, and their thermal insulation index is not much less.
Plastic windows are more popular due to their price and practicality. A more detailed comparison of the two types of windows link to the right.
In any building, one of the most important elements is the door. Since the construction market offers a wide variety in the choice of models, then, accordingly, the designation of doors of different designs in the drawings according to GOST is different, the same applies to marking. It is very important that the designation of the installed models is correctly marked on the diagram.
On drawings with a scale of 1:50 or more, doors must be indicated. An example of a notation scheme can be seen below:

This door designation in the drawing must be present in all diagrams. For example, the table clearly shows that the sliding system is indicated in the form of rectangles with parallel lines going to them, but the swing system is drawn with rectangles and lines going at an angle, etc.
The classification of various doors according to GOST is carried out according to many parameters. One of these parameters is door assignment. If you look at the list of standards for wooden door structures, then they are divided into:
Doors can be either frame or panel doors. In addition, the canvas can be equipped with various transoms and thresholds, but this is not necessary. By the number of leaves, the door leaf can be single-leaf or double-leaf. The sizes of individual valves can be either the same or different. Also, the canvas can be glazed or dull, with a normal or high level of resistance to moisture.
Another sign by which the GOST classifies doors is the direction, as well as the ways of opening the door leaf.
Depending on the mechanisms used in the construction, there are several types of doors.
