It may seem like a secondary issue when building or renovating a house, but we assure you that you will not regret putting it on your priority list. There choice of glass for fixtures it is crucial to ensure maximum living comfort and enjoy significant savings on your bill.
From this perspective, it is very important to ask ourselves: is selective glass or low-emissivity glass preferable?
Let's start with the features
Don't worry, the answer is quite simple and does not require scientific knowledge of materials. However, let us try to outline the characteristics of the two types of glass.
Il selective glass it is obtained through a magnetron treatment with which silver ions are fixed on the material. This material promotes optimal control of both the temperature of the rooms and the incoming light. In fact, it blocks UV and infrared rays and reduces the heat transmitted by windows.
Il low-e glass it is achieved by applying a layer of metal oxides which limits thermal transmittance, i.e. the diffusion of heat towards the outside. This property optimizes the insulation of the house, containing heat dispersion and helping to maintain the ideal temperature.
Advantages and opportunities of selective and low-emissivity glass
In both cases, it is quite simple to see i savings on your bill. But the benefits increase significantly if you select the ideal option for your apartment. First of all, the choice does not necessarily have to be unique. They can be adopted different types of glass based on the exposure of the house and the climate of the place.
In regions where temperatures are quite low throughout the year, it is preferable to opt for low-e glass. The latter in fact contains the use of heating, slowing down the dispersion of heat from inside to outside.
For milder climates, you should instead opt for selective glass which creates a barrier against ultraviolet and infrared rays, preventing rooms from overheating and limiting heating and cooling needs.
In general, it is therefore a good idea to install low-emissivity glass on windows facing north and selective glass on windows or doors located to the south, south-west or south-east.
Therefore remember that it is not a question of choosing either selective or low-emissivity glass, but that it is possible to find the ideal combination for the specific needs of your home.
A professional in the sector, whether an energy designer or a window and door manufacturer, will be able to carefully evaluate the various factors and advise you on the best solution for a green and comfortable.
