Plastic winter screen temperature so the air installation is effective The function of installing plastic
Crooksville windows in winter-: Industry Encyclopedia. Doors and windows, furniture Since ancient times, people have been working hard to maintain the warmth and comfort of their houses and to create all the conditions for a quality life on their territory: they buy all kinds of equipment to enter the houses, create interior designs, and protect the rooms from the cold wind. One of the main elements of a house characterized by respect is the window. Wooden, carved shutters are the only means to penetrate natural solar energy and light. In the modern world, we are increasingly facing technological progress, therefore, plastic windows have won a major welcome in the window design market. Nowadays, the production of windows and the installation of plastic windows have become so popular that Russians are ready to buy and install windows at any time of the year. However, for most of us, the time of winter has nothing to do with construction work, so some reasonable questions arise: Does the installation of windows in winter have any function? What are the reasons to buy and install plastic windows in winter? To answer these questions first, it is worth noting that there is no fundamental difference between the installation of windows in winter and warm seasons. Instead, we can discuss the secondary technical features that must be considered when installing plastic windows in cold or cold weather, please consider the main features.
Many people worry about the penetration of cold air inside and the sharp cooling of the apartment. The freezing of the room at zero or even sub-zero temperature is either the product of too much imagination or the result of the work of unethical installers. In fact, the window opening was completely open to cold air for about 31 minutes. The installation process of the windows takes about an hour, so the apartment will not have time, and the heat of the new double-glazed windows will quickly recover. But you need to know that according to the construction requirements, the installation must be performed at a temperature not lower than -16°. The fact is that the loads generated on the windows during installation are much higher than the loads that must be borne during operation. In cold weather, the profiles and rubber seals lose their plasticity, which complicates the installation of the structure. Therefore, if the window is installed at a temperature lower than -16°, a heat gun or protective screen must be used for so-called Operation. Before removing the old window, the protective screen was installed. In a quarter of the street, metal poles were reinforced to fix the protective screen. Then, the uninflated screen is located in the opening on the street side and fixed to the rod. The pump inflates the screen with air, so that the screen adheres firmly to the wall, ensuring that the warm air is kept indoors. Then remove the old window and install the new window. If a complex removal is to be performed, after removing the old screen but before installing the new window, a screen installation process may be performed. It is the fact that the plastic frame will cool down during transportation, so it is best to postpone the work until the next day to keep the frame at room temperature. In order to avoid errors during installation, this is necessary because the frame changes its linear dimensions when the temperature changes: the cold frame installed immediately will work at room temperature, causing the entire plastic window to fail. Moreover, the cold plastic of the frame becomes fragile and cannot withstand mechanical stress, so the frame with the glass unit must be given a chance. Before installing the sealing material, make sure that its own temperature is not lower than + 16°.
The surface of the joint must be clean and dry, free of frost. Before fixing the tape to the window frame, it should be installed in the opening as much as possible, if possible, in warm conditions, before removing the old block, it should be fixed as much as possible.
When heated with a stream of hot air, it will expand well. The moisture barrier and the mounting strip of the breathable tape are made of butyl rubber. Therefore, in order to better fix the tape on a cold surface, hot air must be used (Not less than 16 cm from the surface) Heating installation strip. The gap between the opening and the window block is filled with polyurethane foam. Polyurethane foam must be specifically designed for winter conditions. Unlike summer foam, winter foam has a certain chemical composition balance, and the use of special additives can promote the polymerization (hardening) of the foam at sub-zero temperatures. After the product is installed, fill the polyurethane foam with a fixed insulation tape to prevent cold air from acting on the fresh foam layer. According to established specifications, foam filling is performed in two steps in winter: first in the cold area of the joint (usually heating the joint and moisturizing the space), and then in the warm area for a second layer of filling. The foam of the assembly seam is completely sealed from the inside. The special film prevents indoor moisture from entering the joints. Therefore, installing windows in winter is not only feasible, but also has certain advantages. First of all, the demand for windows in winter is very low, which means that the installation will be completed on time without rush, in addition, the price of windows in winter will be greatly reduced. Secondly, if you install windows in the summer, the possible defects will only appear after the first few months of cold weather. But in winter, all the shortcomings are immediately felt through draught, condensation or freezing on the glass. In addition, when installing windows in winter, you will immediately feel the difference between the new warmth, airtightness, beauty, neatness and the old dilapidated windows. These changes are not obvious in summer because it is warm and dry outside. This subtle difference will immediately ensure the absolute quality of the product.
Carefully check the window-plastic surface for damage, whether the assembly seams are neat, and whether there are bubbles or foam inside or outside.
Rigidly fixed in the opening-when the sash is opened, the movement of the frame contour is felt. If signs of poor installation quality are found, it is necessary to file a formal claim with the company, detail all the defects, and not sign the acceptance certificate until the defects are eliminated. If there are any complaints about the quality of the installation, the company is obliged to send an expert so that he can find out the problem. The Winter Greenhouse, grow in -40'C (2020)
