The installation of plastic windows has long ceased to be something unusual. It is impossible to imagine a modern home remodeling or construction project without plastic windows. However, when some product grows more and more popular on the market, the number of rumors and myths — both about benefits of buying this product and about its harmful effects on human health — grows proportionally. But don’t believe everything you hear. It’s better to find out more about the product under consideration and make the right decision on your own.
Myth 1: Plastic Windows Do Not Let the Cold In
This one is a fact. Unlike wood, PVC windows have a very low thermal conductivity. This helps keep the heat inside. Special rubber seals and installation materials also enhance the thermal insulation of plastic windows.
Myth 2: Plastic Windows are so Soundproof that You Can’t Hear a Sound Inside
Not exactly. Plastic window profiles do provide some sound insulation indeed, but they are not 100% soundproof. The best option is to install a multi-pane window with the glass of different thickness.
Myth 3: Plastic Windows are Absolutely Water- and Windproof
This is not entirely true, but they will protect you from cold drafts if you use proper rubber seals with them.
Myth 4: There is a Vacuum Inside Double-Glazed Windows
No, there isn’t. A vacuum is a space with no substance whatsoever. A double-glazed window does not have any air inside, but it does not mean there is a vacuum because it’s filled with an inert gas — normally argon or krypton — which provides decent sound and heat insulation.
Myth 5: The Thicker the Double Glazing Frame, the Better the Consumer Properties of a Window
This opinion is absolutely wrong. Unlike their wooden counterparts — where the frame thickness does improve the quality of a window — plastic options should comply with predefined manufacturing standards. Those parameters are experimentally calculated and verified to achieve the best result. If manufacturers try to change them, the quality of plastic windows can deteriorate significantly.
Myth 6: You Can Buy PVC Windows in a Wide Range of Colors and Configurations
Yes, that’s true. A diverse color palette of PVC windows and the ability of manufacturers to fulfill orders of any complexity are an undeniable advantage of purchasing such windows.
Myth 7: Plastic Windows do not Last Long
Yes, they do! They are much less susceptible to mechanical and chemical damages than windows made of wood. The service life of PVC windows is as long as 50 years and longer if you maintain them well enough. It also depends on the quality of components they are made of.
Myth 8: PVC Windows are Easily Flammable
This is not quite true. At very high temperatures, window plastics do not burn — they melt instead. Their ignition temperatures are over 800 degrees Fahrenheit. However, when melting, the material emits carbon dioxide vapors that are very dangerous to human health. In fact, they are no less hazardous than carbon monoxide emitted during a fire.
Myth 9: Plastic Windows are Toxic and Harmful to Health
Well, you can’t call plastic windows exactly environmentally friendly or good for your health. But thanks to modern technologies, this material is not dangerous for human health under normal conditions. It can only be a serious issue in case of a fire.
Myth 10: The More Panes, the Better for a Plastic Window
That depends. Each customer has their own priorities (price, noise protection, heat insulation, frame weight). By choosing multi-pane plastic windows, you can ensure better heat- and noise insulation. However, some people do not want such windows because of their greater weight or poorer light transmission ability.
