Eco-bonus for solar shielding

The Stability Act of 2015 has included solar shielding among the products that, for their contribution to energy savings, can take advantage of the ecobonus, thus allowing the tax deduction of 65% of the expenditure on the purchase and laying in the work of curtains and solar shields.

Solar shields or sunscreens (brise-soleil) are "systems that, applied to the outside of a transparent glazed surface, allow a variable and controlled modulation of the energy and optical parameters in response to the solar stresses."

It is known that solar radiation penetrating into enclosed environments through glazed surfaces, produces the phenomenon called "greenhouse effect" as the sun's rays remain trapped in the environment producing a considerable raising the internal temperature. There are on the market excellent orientable sunbreaker systems that allow an adjustment of internal light, systems that are also "packaged" horizontally, can be installed in place of the common wrapable shutters commonly called "shutters." These are aluminum or wood slats type "Venice" but more robust and equipped with mechanisms and guides, manual or automated, for handling and orientation.

These systems, as well as being very comfortable for light management, produce huge advantages in controlling the temperature of the rooms and saving summer energy in the increasingly widespread air-conditioned environments.

It is essential, however, that the sun shields, sunscreens, Venetians or curtains, are installed outside the glazed surface as if placed inside do not produce any benefit on temperature control because the sun's rays, once once past the glass, they remain trapped inside bouncing on the walls.

Tax deductions are not usable for solar shielding on north-facing windows, as these walls are not affected by direct solar radiation, and for fixed shielding because they have a reverse effect in the winter season, reducing the benefit of sunlight on winter heating.

For those who want to delve into the topic you can consult two very detailed guides published on the website of the Revenue Agency.
