Do I need side walls?

Enclosing off a 20ft gazebo can really make this wide gazebo feel like a very comfortable yet enclosed outdoor space. By adding sides – you can create a nice weather-protected outdoor environment.
However, the purpose of sides is two-fold – added privacy and then ultimately protection from the elements.
It also has a minor thermal effect keeping any hot air more confined to the area and reducing wind chill that could affect. However, heat will still escape.

How do I make my 20ft x 10ft m gazebo weatherproof?

For all of our gazebos and our 20ft x 10ft gazebos are no different the material used is completely waterproof.

We also offer a range of 20ft gazebos with a rain canopy which extends the footprint slightly and adds further waterproof shelter. A great example would be our 20ft x 10ft Gazebo with extended rain canopy

I need a 20ft x 10ft shelter that lasts. Which is best?

All of our shelters come with a 12-month manufacture warranty – and are incredibly durable.
However, if you’re looking to achieve a semi-permanent structure – our 20ft x 10ft Heavy Duty Gazebo is made with a stronger frame than the rest and is built for commercial environments.
