With the energy efficiency objectives in buildings that our country has committed to achieving, the use of solar control glass, which allow to improve the comfort of the rooms in terms of heat e brightness e to reduce energy consumption for air conditioning.
Save energy means reduce energy needs of a building using efficient systems for its satisfaction with a positive balance in terms of costs-benefits.
To make these improvements there are two ways to follow: provide for efficient plant equipment e create an efficient envelope
It is essential to take into consideration that an efficient building envelope offers the guarantee of lower costs in the bill and reduction of CO emissions2.
To create an efficient building envelope, it is necessary to carefully evaluate the characteristics of the windows and the elements that compose them, that is glass and frame.
I solar control glass, can be used for reduce the entry of heat into homes and buildings in areas where the climate is warmer, but also to avoid the phenomenon of solar glare.
In cities and areas with a more temperate climate, this type of glass is used to counterbalance the control of the sun's rays with a high transmission of natural light.
Features
Il solar control glass is indifferently called "selective" or "low emissivity" , although these two types do not have the same meaning in practice.
The main difference between the two types consists of the side where the coating is applied, as well as in other technical and production characteristics.
The coating of both glasses consists of type metal oxides magnetronic or pyrolytic.
In the first case the coating is deposited for pyrolysis, a hot process by which the coating is melted and incorporated into the glass, making it more resistant to bad weather and suitable for outdoor use.
The main feature of the selective glasses is that of perfectly transmitting light radiation and rejecting infrared radiation, especially the one with a lower wavelength (called thermal radiation) as the glass acts as a shield from UV and infrared rays.
With the use of selective solar control glass it is also possible to avoid the use of screening systems, such as curtains, blinds and shutters, and you will have bright and much cooler interior spaces.
In the second case, with i low-emissivity glasses, the metal oxide coating on the glass is deposited by a process electromagnetic, it is not very resistant to atmospheric agents and must therefore be placed inside.
I low emissivity solar control glass, like the selective ones, they allow the passage of light radiation, avoiding the passage of infrared radiation (in this case the one with a higher wave frequency) preventing the dispersion of heat towards the outside.
On the market there are solar control glasses that group both characteristics, generically called low emissivity, therefore in this definition it is often possible to find also the characteristics of selective glass.
