GreenShield™

Product Discription

GreenShield™ is an SBS modified bituminous 4mm membrane. It has specific anti-root additives and is particularly flexible at low temperatures.

Features & Benefits

• Compound

The waterproofing compound of Green Shield membranes is made up of a mix of empty residue distilled bitumen modified with elastoplastomeric polymers based on atactic polypropylene, isotactic polypropylene, synthetic rubber, specific anti-root additive and stabilizing aggregate fillers. The compound is UV rays resistant, thermally stable and particularly flexible at low temperatures.

• Reinforcement

The reinforcement used for Green Shield membranes is made up of a non-woven polyester mat stabilized with glass fibres, which gives to the product very good mechanical and breaking elongation characteristics, as well as very good dimensional stability. Such characteristics allow to use these membranes also on mechanically and thermally stressed surfaces.

• Outside Finishing

The Green Shield membrane is treated on the upper side with non-stick filler; other finishings such as polymeric film and non-woven may also be used. The lower side is finished with PE torch-on film; other finishings such as aggregate, polymeric films, nonwoven non-stick polymers may also be used.

Uses

The GreenShield™ membranes are planned to be used as under and middle layer, top layer, under heavy protection, against humidity from soil, for roof gardens.

Application Instructions

The laying deck shall be clean, smooth and dry. The membrane is then laid by melting the lower side with light propane gas flame. Edges shall be overlapped, always by torch, by at least 10 cm. on the sides and 15 cm. on top so that the roofing watertightness is maintained.

Please refer to specific specifications provided by your Regional Technical Manager.
