How do windows affect the energy efficiency of a home?
I think each of us wants to save energy. This is good for both the environment and our finances. One of the ways to save energy is to use energy efficient windows. Their installation in new homes is becoming more and more popular, but what are energy-efficient windows and how are they built?
Construction of an energy-saving window
When buying windows for your home, you should think about choosing energy-efficient windows. As their definition implies, they allow you to save energy, which is directly related to lower heating or air conditioning bills. When choosing such windows, you need to pay attention to:
profiles,
windows,
spacer frame.
In energy-saving windows, profiles must have Uf insulation of no more than 1.1 W/ (m2 * K). The glass in such windows must be combined with triple glazing, which is filled with noble gas. Most often it is argon or krypton . The maximum heat transfer coefficient Ug of such window panes can be 0.7 W/(m2 * K). In addition, low-emission glasses coated with a layer of precious metal oxides invisible to the eye should be placed both inside and outside. The purpose of this treatment is to reflect the heat back into the house. The advantage of such glasses is that they allow solar energy to pass through, which makes it possible to heat the building. The remote frame in energy-saving windows cannot be made of aluminum. It is made of stainless steel or plastic.
Currently, windows consisting of two or three panes separated by dividers are the standard. When buying new windows, you should pay attention to information about their thickness and quantity, as well as the width of the gap between the panes. In addition, the product documentation also contains information about the type of gas used. If we notice argon 4-16-4, it means that the two panels are 4 mm thick, and there is a space filled with argon 16 mm between them.
Window manufacturers add a third pane to increase thermal insulation. In addition, they replace argon with krypton, and this is how energy-efficient windows are built.
Uw, i.e. the most important factor of energy-saving windows
When buying energy-efficient windows, we need to know what kind of energy efficiency it is. The energy efficiency of a window is determined by its ability to minimize heat loss, which is used for indoor heating and air conditioning in summer. The biggest reason for heat loss is the heat transfer coefficient of the entire window. It is described by the value of the heat transfer coefficient Uw. In addition, the tightness of the window is also important, which is determined by the air permeability class.
The Uw coefficient is expressed in W / (m2 * K). It reports the amount of heat that has passed through the window. The lower the value of this coefficient, the more energy efficient the window will be, and we will pay less for heating. Traditionally, energy-efficient windows are products with a Uw coefficient below 1. It is worth adding that this value is most often found in windows with three panels. Big spenders deserve special treatment. High roller bonuses are designed for players who deposit large amounts, typically 500€ or more per transaction. When you use a 1xbet app promo code nd make a substantial first deposit, the bonus percentage may increase, or the maximum cap rises significantly. For example, instead of 100% up to 130€, a high roller might get 100% up to 500€ or 50% up to 1000€. The wagering requirements for high roller bonuses are sometimes lower than standard offers. Some casinos also offer personal account managers, faster withdrawals, and exclusive promotions before registering.
