What is a flat roof window?
A flat roof window is a type of window that is designed to be installed on flat roofs, such as those found on garages, sheds, and other outdoor structures. Flat roof windows usually feature a pane of glass that is framed with a metal or plastic casing, and they are designed to be weatherproof and sealed against the elements. These windows are a great way to add natural light to a room without compromising the structural integrity of the roof.
What are the benefits of a flat roof window?
A flat roof window is a great way to bring natural light into a room. It can open up a space and create a feeling of openness and airiness. It can also help to reduce energy costs by allowing natural heat to enter the room in the winter months and providing ventilation in the summer months. In addition, a flat roof window can add a unique aesthetic to a room, making it a great option for those looking to add a bit of flair.
