Buying windows and doors for a home is an investment for many years to come. Therefore, before considering such a decision, it is necessary to analyze and compare the offers available on the market. At the same time, we take into account the quality of doors and windows, their appearance and price. Manufacturers provide many parameters of windows and doors on their websites on the Internet.
How to understand them so as not to get lost in the flow of information? What do I need to know before visiting the store? What should I ask the seller and what should I pay attention to during my stay in the store?
When building a house, it must be remembered that windows are best installed after the walls are erected and the roof is installed, but before the facade is finished. The purchase of windows should be considered in advance so as not to delay the next stages of construction and finishing.
Thermal conductivity index of windows
The main thing to pay attention to when choosing windows and doors is the Uw thermal conductivity index. It depends on how much heat will escape from the building through the windows and doors. This parameter is defined in units of Watts/m.kv*K, and its low value means insignificant energy losses.
Ut and Ug indicators are present in some technical characteristics of windows and doors.. They relate to PVC profile and glass, respectively, so they do not reflect the actual level of heat loss. It can be recognized by the Uw indicator.
International rules precisely define the acceptable level of the Uw indicator. For windows, it is 1.8 W/sq.m.K, and for doors – 2.6 W/sq.m.k. Products with lower parameters should not be taken into account.
However, if you want to save money on heating, you can buy energy-efficient models of doors and windows. Many manufacturers present their energy-saving products on the market, however, windows that actually reduce energy losses in the house are characterized by a Uw value below 1.2 W/sq.m.
When comparing the thermal conductivity values, it is also necessary to verify whether these values are valid for the standard version. Sometimes it may be necessary to purchase additional items in order to obtain the specified parameters.
Window profile classes
The symbols A, B, and C define the profile class. This is a very important property, as the profile is responsible for proper insulation and strength of the frame and box. The highest class is indicated by the symbol A. The outer walls of such a profile have a thickness of at least 2.8 mm. The design of this type guarantees that the window does not deform over time. Cryptocurrency betting is growing fast due to privacy. Many modern platforms now offer crypto welcome bonus offers for Bitcoin and Ethereum users. These bonuses often have higher limits and lower wagering requirements because crypto transactions have lower fees for the bookmaker. If you deposit using BTC, you might get a 300% match instead of 100% for fiat currency. However, check the volatility rules. Some sites calculate the bonus in USD value at the time of deposit. Crypto payouts are usually the fastest, often taking less than 1 hour. This makes crypto sites ideal for players who value and speed above everything else.
