Choosing windows is a decision that affects the comfort, safety and economy of the household budget. It is not just limited to aesthetics – it is a thoughtful investment in the quality of life. In this article we will look at the key parameters to consider when choosing windows: Uw, Rw, Lt and G coefficient.

Uw Factor - Thermal Efficiency of Windows
Meaning of Uw Factor
The Uw coefficient determines the thermal efficiency of a window, or its ability to retain heat inside a room. It is a value that tells us how much heat (in watts) escapes from a square meter of window at a temperature difference of one degree between the interior and exterior. The lower the value of the coefficient, the better the insulating properties of the window, which translates into less heat loss and lower heating costs. In an era of rising energy prices, choosing windows with a low Uw heat transfer coefficient is becoming not only a matter of comfort, but also an economic necessity.
How does the Uw coefficient affect the choice of a window?
When choosing windows, it is worth paying attention to how manufacturers list Uw values. Windows with Uw = 0.74 W/m²K, which can be found in our offer, are an example of products with high thermal efficiency. As a result, even on the coldest days, interiors remain warm without excessive use of heating. This, in turn, translates into real savings in the household budget.
Practical aspects of Uw coefficient
When choosing windows with a good Uw coefficient, it is also worth paying attention to other design elements that can affect thermal insulation, such as the type of glazing, frame or gaskets. All these elements determine the final value of the Uw coefficient and thus the energy efficiency of the entire window.
Acoustic Insulation Rw - Silence and Tranquility in the Home Retreat
What is Rw and why is it important?
Sound insulation Rw is a parameter that determines a window’s ability to dampen outside noise. Expressed in decibels (dB), it tells us by how many decibels a window is able to reduce the level of sound penetrating into the interior. In the context of urban hustle and bustle, busy streets or noisy neighbors, a high Rw is invaluable. Windows with an Rw coefficient of 38 dB, which our company offers, provide a significant reduction in noise, which is tantamount to greater comfort for residents.
Choosing windows with the right Rw
When choosing windows, it is worth paying attention to their sound insulation, especially if our house is located in a noisy neighborhood. Windows with high Rw can significantly improve the quality of life, providing peace of mind and protection from unwanted noise. It’s an investment in mental health, as constant noise can lead to stress and fatigue.
Technologies and materials affecting Rw
The Rw value depends on a number of factors, such as the thickness of the glazing, the type of gas filling the space between the panes and the presence of special acoustic films. These technologies are becoming increasingly available and offer an effective barrier to various types of noise, from urban hustle and bustle to the sounds of nature.
Light Transmittance Lt and Solar Factor G - Light and Heat Optimization
Lt - Natural Light for Your Home
Light transmittance Lt is a parameter that determines how much natural light penetrates a window. It is expressed as a percentage and has a direct impact on the brightness and atmosphere of a room. Windows with a high Lt coefficient, such as those with a value of 74%, provide an abundance of light, which is not only beneficial to our well-being, but also saves electricity during the day.
G - Solar Energy Utilization
Solar G-factor is an indicator that tells us how much heat from the sun is transferred through the window. A G-value of 53% means that the window allows much of the sun’s energy to be used for natural space heating. This is especially important during transitional periods, when every ray of sunlight can help reduce the need for artificial heating.
Importance of Lt and G in window selection
When choosing windows, it is worth paying attention not only to their thermal and acoustic insulation, but also to how they affect the microclimate inside the rooms. Windows with properly selected Lt and G parameters can significantly improve the comfort of life, providing the right amount of light and solar heat, which has a positive impact on our health and well-being.
Applications
When choosing windows, you can not limit yourself only to the parameter Uw coefficient of the window. Also important are such aspects as sound insulation Rw, light transmittance Lt and solar factor G. All these coefficients together create a picture of an ideal window that not only saves energy, but also provides comfort, silence and harmony with natural light. Remember that windows are an investment for years, which affects the daily life of each of us. Therefore, it is worth taking the time to carefully study the parameters that translate into the quality and comfort of our home environment.
