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.
