Outdated wooden window frames are replaced by plastic analogues that the store can offer Wido at a very nice price. When changing the frames, the user has the question "How to choose the right PVC windows?". Now let's look at this in detail.
Advantages of PVC windows
Plastic windows quickly gained popularity due to the following advantages:
1. It is not necessary to constantly paint the frame
2. In the autumn and winter period, there is no need to insulate the frames. Good thermal insulation
3. Better sound insulation
4. They last much longer than wooden frames and do not rot
What to look for when buying
It is necessary to carefully approach the choice of a plastic window and not run into an unscrupulous seller.
• First of all, we look at the number of air chambers in the double-glazed unit and profile
Polyvinyl chloride is the basis of all plastic windows. But it can use both primary and secondary PVC. The first one is considered better. Unfortunately, you will not be able to distinguish the material yourself. All that remains is to look at the quality certificates, which are definitely available at the verified store https://wido.com.ua/. According to GOST, PVC windows last for 20 years, but some manufacturers guarantee even 40 years.
Also, when buying, pay attention to the letter designations: A, B, C, M. A,B,C are the thickness of the outer wall of the profile. It is best to take "A" with a thickness of 3 mm or more. "C" is suitable for non-residential premises. And "M" is a frost-resistant version of the profile. If you live in a cold region and you have harsh winters, I advise you to pay attention to this marking.
• Number of air filters
The thermal insulation of your room depends on them. At least two filters, for Ukraine they usually make three or more chamber profiles. Why? Because they correspond more to our climatic conditions.
Usually, residents of megacities choose windows with five chambers, so that there is more sound insulation. But because of the number of cameras, the thickness of the window itself increases, and the weight. Therefore, it is better to choose a three-chamber version for a cottage made of timber, SIP panels or balcony glazing
• Profile width
The width is determined by the number of vertical cameras. The more of them, the wider the profile. Usually the size is from 58 to 90 mm. A profile with a width of less than 58 mm will not withstand even a double-glazed unit. A width of 90 mm is used in industry or when building a winter garden. Average value up to 70 mm, it will suit us.
• Reinforcing liner
A reinforcing insert is installed in the middle chamber of the plastic window. It is made of galvanized steel, it is not subject to corrosion. The larger the steel, the heavier the block and the more expensive the window. The width of the steel is 1,2-2 mm. If it is thinner, it means that the manufacturer cheated in order to raise the price.
• Sealant
When buying a window, pay attention to the quality of the sealant. If the "rubber" is of poor quality initially, after a few years you will have to call the master with the words "I have a draft at home."
It is the sealer that is responsible for sound insulation, heat insulation and protection of accessories from dust and moisture.
There are 4 types of main sealants:
— TEP
- Silicone
— Rubber
— EPDM
Out of the four options, the EPDM sealant will be the best choice. It withstands temperature changes well, is not as expensive as silicone, is durable, and does not deform much. Or choose a rubber seal, of course it can crack in the heat and cold, but it is not so expensive and it is easy to change. Silicone sealant is very expensive and if it breaks in one place, it will have to be completely replaced, and it tears at the slightest tension. TEP is the cheapest and non-durable option, it quickly deforms from heat and cold, and will not return to its original state.
• Fittings
Accessories also affect the durability of the icon design. Don't spare money for the purchase of accessories, they should be of high quality and from leading manufacturers, if of course you don't want to constantly spend money on the purchase of a new window.
Let us remind you that we do not install a plastic window for one day or one hour. It is necessary to approach the choice of all elements of the PVC window responsibly. Do not spare money for your own comfort, sound insulation and heat insulation.
