APP waterproofing membrane (-25°C)
Elasto-plastomeric prefabricated waterproofing membrane whose compound is composed of distilled bitumen, plastomers, elastomers and polyolefin’s (APAO) obtained from Metallocene catalysis polymerization, with molecular weight and selected tacticity. The P and PA versions are reinforced with a woven non woven single strand composite spunbond polyester fabric, offering very high mechanical characteristics and excellent dimensional stability. The PA versions are self-protected, on the upper face, with mineral slates which reduce superficial heat absorption improving the durability of the membrane. The self-protected versions have a lateral selvedge of 10 cm, and on request, a head selvedge of 15 cm to improve the adhesion between the sheets.
