Adverse weather conditions?
Whilst the Clearspan structure can cope with harsher weather conditions than traditional marquees, it is still a temporary structure and can be vulnerable in extreme wind conditions. Snow is also a hindrance to the Clearspan system as the weight can put a strain on the covers in extreme conditions. Under these circumstances, heating levels need to be increased to keep roof sections clear.
On a smaller scale, windy conditions and torrential rain can result in it becoming noisy within the marquee - while excessive rain can cause the area surrounding the marquee to become soft and muddy on a grassy site.
