How Condensation Affects Gazebos and Canopies

How Condensation Affects Gazebos and Canopies

Condensation affects all canopies, as well as tents, anoraks and other waterproof materials. Single-walled and double-walled gazebos can all be affected by condensation. 

If you need a refresher from your science classes, condensation is formed when water vapour cools, and goes from gas to liquid. There is always some water vapour in the air - even the driest places on Earth have some humidity, so Ireland and the UK have plenty!

Therefore, over time, moisture will form from cooling water vapour on the sidewalls and canopy roof of any waterproof structure.

Minimise condensation in your pop-up gazebo

To minimise condensation in your gazebo, keep it well-ventilated when possible. Condensation will even occur overnight or when the gazebo is not in use, so if possible, leave the gazebo open and ventilated when unoccupied.

If your gazebo is forming condensation, this can be wiped away quickly with a towel.

How to spot condensation

Condensation is a moisture that coats the walls of your gazebo; leaks only allow in water from one location. Condensation can start from the ground, which is typically coldest, and rise up, or can form in pools and puddles around the fabric. 

A leak should clearly be allowing water to travel from the exterior of your gazebo to the interior. Condensation is created naturally from the ambient air inside your gazebo.

Gazebo Heaters

You may wish to use a gazebo heater to minimise condensation. Keeping your gazebo warmer than the surrounding area will prevent water vapour from cooling on your marquee walls. 

Do not use any flames or gas heaters in your gazebo; these should only be used outside for safety reasons. Halogen gazebo heaters are the safe option for warming marquees and gazebos.
