General Membrane Sagitta
This is an APP (Attactic Polypropylene) plastomeric type modified waterproofing membrane. It consists of a specially formulated bituminous compound of distilled asphalt that is modified with selected high grade visco-elastic polymers and inert filler. APP material has a very good heat stability, very high softening point and good workability, specially in sub-tropic and tropic climate (like the Philippines). It can also be used in the exposed roofing system.
Physical and chemical Properties : APP modified compound
• Excellent cold flexibility - 0°C
• Excellent UV resistance
• Excellent elongation
• Excellent resistance to aggressive chemicals
• Extremely good elastic memory
• Excellent resistance to chemical agents and pollutants in the atmosphere
TWO TYPES OF SAGITTA :
Type(A) - (1) SAGITTA P Non-woven spunbond polyester carrier : • High mechanical characteristics • High elongation • High puncture resistance • Will not decay |
(2) SAGITTA P 4KG Mineral slate chip finish • UV barrier increasing product life • reduces spread of flame • allows a range of different colours for the cap-sheet |
SAGITTA P is based on filaments of polyester which are then welded together. It is for this reason that it is called Non-woven.
This product has a good mechanical strength, and has a good dimensional stability.
The data beneath proves it so :
Tensile strength longitudinal / transversal Elongation Tear Resistance |
= 400 / 300 N / 50 mm = 35% = 130 N |
SURFACE PREPARATION
Areas where materials are to be installed using the “torch-on” method must be clean, dry, smooth and treated with primer to ensure good bonding between the membrane and the sub-strate. The roof should also have appropriate falls to ensure that water will run towards the drains, and not cause ponding on the roof.
