Myths about metal-plastic windows: truth and fiction

This post examines the common myths about metal-plastic windows, and explains the truth from the fiction. It explains why metal-plastic is becoming increasingly popular with new and existing window installation projects, and reveals the advantages, such as greater insulation, air and water tightness, as well as increased resistance to heat, cold, and noise. It also emphasizes distinctive features such as fire-resistance, sustainability, and noise-control capabilities. Furthermore, the post provides useful advice about when it is best to install metal-plastic windows for optimal results.

The more popular metal-plastic windows become, the more myths and fictions are formed about them. Sometimes such statements do not quite correctly reflect reality, and sometimes they are completely opposite to the truth. Letโ€™s try to figure out what these myths are and how much truth is there in them.

The first myth.The thinner the profile walls, the cheaper and lower-quality windows. The situation in this case is exactly the opposite. Initially, the first profiles of metal-plastic windows were cast from low-strength polyvinyl chloride (PVC), which had a number of disadvantages, the main of which were susceptibility to mechanical destruction and aging. The only way to avoid damage was to form a window profile with the thickest possible walls. Of course, this increased the cost of the window as a whole..

However, the chemical-technological industry is developing very, very intensively. Soon, various plasticizers, additives and other chemical components that improve the physical and mechanical properties of PVC began to be added to polyvinyl chloride when casting a profile. Thus, manufacturers have achieved the opportunity to improve the quality of the profile, while simultaneously reducing its cost and the total weight of the finished window, which is reflected in the operational characteristics in the best way..

The second myth.The thinner the walls of the window profile, the worse its thermal insulation properties. This statement is fundamentally wrong. Why? Because thermal conductivity and thermal insulation depend on the thickness of the non-conductive heat layer. In the window profile it is not the PVC profile wall, but the air gap between the profile sections. The โ€œwarmthโ€ of a window profile depends on its width, as well as on the presence of cameras in the profile cavity. The more cameras, the warmer the profile. In addition, in the entire window structure, it is the double-glazed window that is the greatest conductor of cold, not the PVC profile. That is why worrying about the thickness of its walls is, at the very least, pointless.

The third myth.Class B thin-walled profiles can only be used for installation in non-residential premises. This statement is also far from the truth. According to GOST, profiles of classes A and B do not differ in their use. In addition, the lower cost of products, in which the B profile is used, ensures the constant demand for such window systems among consumers..

The fourth myth.Class B profiles are used only in the production of cheap and low-quality metal-plastic windows. In fact, the technical, including the strength, characteristics of class B profiles are identical, and sometimes even exceed the corresponding indicators for structures from a class A profile. There is not the slightest reason to attribute unreliability or low wear resistance to thin-walled profiles. The difference is only in the technology of manufacturing the window profile and its cost for the manufacturer.

The fifth myth.Thin-walled profiles do not last as long as class A profiles. To understand the veracity of this statement, you should refer to the main technological document โ€“ GOST. In GOST we find the corresponding section on window profiles. It states that the quality requirements for thin-walled and thick-walled profiles are absolutely identical. In addition, even the conditions of installation and operation of windows equipped with these types of profiles do not have the slightest difference. That is why we have every right to assert that class B profiles are in no way inferior to thick-walled profiles, which means that when buying windows with this type of profile, you should not worry unnecessarily about their quality and durability..

    Are there any actual disadvantages to having metal-plastic windows, or is it just a misconception? Iโ€™ve heard various myths about them, but Iโ€™m curious to know the truth. Are they less durable or energy-efficient than traditional windows?

      While metal-plastic windows have their advantages, such as being cost-effective and low-maintenance, they do have some disadvantages as well. One common concern is that they may be less durable than traditional windows, as the plastic components are more susceptible to damage from extreme weather conditions and physical impact. Additionally, metal-plastic windows may not be as energy-efficient as other types of windows, as they tend to have poorer insulation properties. However, the actual performance of metal-plastic windows can vary depending on the quality of materials used and the installation process. It is important to carefully consider these factors before choosing metal-plastic windows for your home.
