Industrial DSD

Eco Shield™ DSD is a six-layer laminate consisting of two outer layers of aluminium foil, one layer of spunbond, one layer of reinforcing scrim and two layers of laminating polyethylene. It is a top of the range product and carries the SANS 1381-4 Class A mark certification.

The reinforcing scrim provides additional strength and stability making the product ideal for industrial applications.

Eco Shield™ DSD has a B/B1/2/H fire rating which means it has a superior fire resistance and can be used in any structure with a B1 fire rating with sprinklers.

Installation Instructions
1) Domestic specifications
One layer of Eco Shield Industrial over rafters and under battens. Lay Eco Shield longitudinally over the rafters working from the eaves to the ridge and lapped 100 mm at joints.
2) Industrial specifications
Fix strainer wires from ridge to eave purlins at 300 to 600 mm centres depending on the application. The wires must run on top of the purlins. Lay Eco Shield Industrial over the strainer wires from the ridge to the eave. Secure Eco Shield to leg face of top purlin, pull taut down to the eave and fix to bottom purlin, pull taut down to the eave and fix to bottom purlin in similar manner. The Eco Shield should be overlapped 150 mm at each point to ensure that the strainer wires support each lap.
Special precautions
The foil layer has a poor resistance to acids and alkalis and must not be used in contact with wet concrete or be exposed to a corrosive environment. Unless special precautions are taken, the atmosphere in the roof space can cause corrosion of the foil layer that will directly effect its emissivity and therefore its  thermal insulation properties.
