Extra Span Shield

Extra Span Shield


The Extra Span type shield (formerly known as the Mini ES Shield), as a product, sits between the Mini type shield and the Ladder type shield.

The Extra Span type shield is used as a permanent solution for protect both personnel and equipment from the harsh weather conditions experienced both onshore and offshore in the oil and gas industry.

They are of a single layer construction but can be altered to provide a double layer of protection. Intended for protection of key equipment and in areas where personnel will not come into direct contact with the radiant shields.

The shield is of a single layer construction which can reduce the wind speed by up to 62% without affecting light transmission and ventilation. This can be further expanded by adding an additional layer which will reduce the wind speed by up to 72%. Protection against radiant heat is also provided.

The Extra Span Shield has been successfully tested to wind speeds in excess of 100mph.
