Plastic windows are gaining popularity year after year, and many want to know what the reason for this reputation. The main component of the windows is the frame, which is made from the PVC profile (polyvinyl chloride). Previously, the base of the frames was metallic, and cladding made of soft polyvinyl chloride. Later they began to produce frames from solid PVC, strengthening the profile with metal, or wooden liners. Modern polyvinyl chloride is made from oil and table salt. This material is environmentally friendly and does not distinguish toxic substances (lead stabilizer is replaced by calcium-zinc). Plastic windows are popular due to the low price, similarity with the characteristics of wooden windows and a long service life.
Anyone who decided to install in the apartment, or in the office of plastic windows, asks the question: what windows should you choose? When choosing windows from PVC, it is necessary to pay attention to such characteristics as noise insulation, thermal insulation, ventilation, durability and protection against hacking.
The level of thermal insulation depends on the size of the window and sash, the quality of the assembly and the type of double -glazed window (single -chamber, two -chamber). A single -chamber double -glazed window is recommended to be used for warm climate, and a two -chamber is suitable for medium -widths. If you live in a very noisy area, then it is best to install windows with a double -glazed window of different thicknesses (resonance decreases). Noise insulation is increased by increasing space (between double -glazed windows), as well as fill the camera with gas (argon, crypton).
For better ventilation, it is recommended to install a ventilated profile, but condensation may form on the windows. Safety will ensure hacking accessories, fireproof and armored glasses.
