types of opening of shutters of plastic windows Deaf windows. Stationary construction of a frame and a double-glazed window. Blind windows do not have fittings and do not open. Most often they are installed as an element of a multi-leaf window or as a showcase. Tilt and turn window. This is the standard and most common type of opening, it is suitable for houses and apartments. The mechanism opens in a horizontal and vertical plane, it is suitable for rectangular, arched and trapezoidal structures. With this option, micro-slit ventilation is possible. Fanlight (windows with a transom). Shtulpovye windows (oar). Their shutters open in one plane and, as a rule, open into the interior of the room. Sliding blocks. Such windows are the right choice for rooms with limited space. They are ideal for glazing loggias and balconies.
Multifunctional double-glazed windows have good light transmission. Due to the thickness of the profile, they are resistant to mechanical damage.
Reinforced profile PVC profile and negative temperatures One of the important characteristics of metal-plastic windows is frost resistance. This is the ability to maintain the integrity of all elements and heat-saving properties at a certain temperature. For the Russian climate, it is necessary to choose windows marked with the “M” index - frost-resistant. They retain all their characteristics down to -20 0C.
Metal strips are hidden inside the profile and act as a strength enhancer. Sometimes windows of a similar design are called metal-plastic, which is more true than just plastic or PVC. The function of metal inserts is very important to ignore.
Certificate of conformity to GOST 30673-2013 for the profile, test reports for intra-profile ventilation, conclusions of laboratory tests for durability and resistance to climatic influences, as well as other documentation confirming the quality of the exprof profile, you will find in the appropriate section on the website.
In the event of failure, such a seal can be easily replaced without resorting to calling repairmen. TPE seals are sold in stores, on websites or in the market. They are inexpensive. It is only important to notice the damage in time so that the repair does not fall on the cold season, when it is not very convenient to open the window.
What else to look for when choosing plastic windows We talked about the main parameters of window structures - they should be taken into account when choosing in the first place. However, there are other characteristics that you should pay attention to in order to choose the best option in terms of thermal protection, sound insulation, durability and ease of use.
TPE seal Flexible thermoplastic (TPE) seals are one of the most widely used seals due to their ability to be used on automated assembly lines. It is very convenient for welding, easily changes its shape when compressed by the sashes, quite firmly fills the junction area and seals the window under normal operating conditions.
Well-known manufacturers of high-quality plastic windows, as a rule, complete products with high-quality seals that are resistant to deformation, soft and elastic.
Plastic windows do not surprise anyone now, they are installed almost everywhere - from shops and offices to luxury apartments and three-story mansions. But their quality is completely different. If at the beginning of their “biography” plastic windows were exotic structures that looked like a degraded version of serial wooden ones, as they say, “soviet”, and practically equaled them in quality, then at a price they clearly went into the premium segment. But in the process of technological development, they have turned into a completely competitive tovary, which has a number of unique properties.
