Lamella roof vs. awning

When planning a terrace roof, the question often arises whether to choose a slat roof or an awning. Both products provide protection from the sun and rain, but there are differences in functionality, design and price. In this article, we will compare the advantages and disadvantages of slat roofs and awnings, so you can make the right choice for your needs.

Louvered roofs are roofings that consist of movable louvers that can be opened or closed as needed.

Awnings, on the other hand, consist of a fabric cloth that is stretched over a frame and can be extended and retracted manually or motorized.
