COMPOUND
SAGITTA membranes employ a compound consisting in distilled bitumen modified with plastomeric polymers (APP).
The good resistance to thermal ageing and flow resistance at high temperature makes these membranes particularly suited for use in temperate and warm climatic areas and for application on thermally-insulated roofs.

REINFORCEMENT
SAGITTA membranes are available with different reinforcements:

+ Rot-proof non-woven polyester fabric stabilized with fiberglass. These “composite” reinforcements combine the excellent mechanical properties of polyester reinforcements with the extraordinary thermo-dimensional stability typical of glassfiber and guarantee high levels of performance to the membranes.

+ Rot-proof stabilized fiberglass reinforcements offering excellent dimensional stability and avoid unsightly wrinkling of the membranes and shrinkage of the waterproofing surface.

SAGITTA can be supplied with either a sanded, talc or slate chip (mineral) top finish, while the bottom surface can be smooth or embossed and protected by a heat sensitive non-stick film PE/PP or sand. Since the SAGITTA compound is virtually unaffected by UV radiation, the membrane can be left without further protection. However the system is also available with the membrane’s upper surface coated with slate flakes that lower the membrane’s temperature when exposed to intense sunlight, which in turn all have the effect of slowing down the ageing process, increasing the life of the system. 

WAREHOUSING & FIXING DIRECTIONS
Material has to be stored in a covered place; it is advisable not to exceed 12 months. Rolls must be stored vertically on pallets or on flat surfaces. Protect the membrane from extremely low temperatures and stabilize the material before its installation, leaving it at least 24 hours in a room at +5°C. All General Membrane products can be installed loose laid, partially bonded or fully adhered as required by the specification of the contractor. It should be noted that this refers only to the first layer of a multiple-layer system and that all subsequent layers should be installed fully adhered to the previous layer. For a correct use of the products, please refer to the specific technical documents issued by General Membrane Spa. If any law, norm or regulation different from what declared by the manufacturer is in force in the Country where the product must be installed, it must be considered as compulsory by the applicator. It is his own responsibility to follow the suitable legislative references.
