Retractable awnings have a specific kind of functionality – they will fold in and out on a mechanical arm as required, providing shelter for your patio area, or allowing you to enjoy full sunshine as required. However, there are also different kinds that you can choose from. For example, if you have a business or a home where you want to install an awning, you will be looking at different kinds – commercial awnings will tend to be a lot stronger, and will be available in bigger sizes.
If you choose a retractable awning, then there will be different cassette types as well. A full cassette means the awning will fold away fully, so that all of the fabric on top is completely covered. This will give it maximum protection from the weather. If the area is already somewhat protected, you can choose a semi cassette awning that will not give as much protection to the material.
