Manufacturers have come up with new designs which provide buyers with a huge variety of no-leak, energy-efficient skylights and by just touching a button, you can ventilate a room.

The current skylights can also be used in corporation with solar blinds as a way to improve energy efficiency. These blinds can either be operated electrically or manually and are available in numerous varieties of light blocking or light diffusing materials.


Skylights are directly attached to your building’s roof and allow ventilation and sunlight to reach all the areas where you need light. Skylights tend to provide some warmth which in turn helps to cut of cost spent on lighting, cooling and heating the building.
