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.

Easy Connect Maintenance Shield

Easy Connect Maintenance Shield


Locker Heatshielding, in conjunction with our partners at Galebreaker, have developed a range of Heat and Wind shields which are aimed at the maintenance and short-term installation market.

Fixings and Safety


The shields incorporate a patented ratchet mechanism to tension panels in place. They are easily connected to existing platform steelwork, directly hooking to an aligned flange, using either Lindapter CF connection technology where a flange is perpendicular to the shield, or split clamp mechanisms for connecting to SHS.

Quick to install, the shields can be placed in any area where protection from radiant heat and adverse weather is required without the need for additional supporting steelwork. The Maintenance shield is supplied in standard lengths for installation in the majority of locations with additional extension pieces provided to extend the length as required. Extensions are attached using the ratchets on the rear which are then covered by flaps which are laced to the extensions to create a continuous shield.

On completion of the maintenance work the shields can easily be dismantled and stored away for the next scheduled work.
