ESHADURO APP -5 | Plastomeric bituminous membrane
APP plastomeric bituminous membranesDescription
ESHADURO is a polymer-modified bituminous membrane based on atactic polypropylene (APP), designed to provide reliable waterproofing and long-term protection in hot climatic conditions. With a softening point of ≥145°C and resistance to temperatures up to 115°C, it meets the demands of the Greek sun whilst retaining flexibility at -5°C. It stands out in the APP range for two reasons: it is available in five types of reinforcement — including the polyester-mesh combination with isotropic mechanical behaviour (640/600 N/50 mm) — and offers four top-coat options, including the brown-red granules for waterproofing pitched tiled roofs and quartz sand. It is the most economical entry-level product in ESHA’s APP range.
The ARGYNET View: The most affordable of the three APP products, with the unique advantage of brown-red granules beneath roof tiles. Important design note: unlike ESHAGUM and ESHAPROOF, it is not certified to EN 14695 for bridge decks — for such projects, a higher grade should be selected.
Overview
Key Features
Resistance to weather and thermal conditions
- Resistance to ultraviolet (UV) radiation
- Resistance to ageing over time
- High resistance to high temperatures up to 115°C (EN 1110)
- Softening point ≥145°C (EN 1427)
- Flexibility at low temperatures down to -5°C (EN 1109)
- Good performance in corrosive environments: acids, inorganic salts, gases, pollution, ozone
Mechanical properties
- Tensile strength from 300/200 to 850/650 N/50 mm depending on the reinforcement (EN 12311-1)
- Isotropic behaviour 640/600 N/50 mm with polyester mesh reinforcement
- Elongation at break up to 45/55% (Spun Bond SP)
- Tear strength up to 350/350 N (ASTM D4073-94)
- Static puncture resistance up to class L3 (15–25 kg) (EN 12730)
- Dynamic puncture resistance: Class I3 (EN 12691)
- Dimensional stability from -0.1/+0.1% to -0.4/+0.3% (EN 1107-1)
Reinforcements — 5 options
- High-quality glass fibre fabric — dimensional stability, most economical solution
- Non-woven polyester — balance of strength and cost
- Polyester fabric with embedded glass fibres — maximum stability during heat-sealing, prevents ‘banana’ effect
- Polyester-mesh combination — isotropic behaviour in terms of mechanical properties
- Spunbond polyester (SP) — increased resistance to tearing, puncture, shear and tensile stress
Coatings — 4 options
- Green, white or brown-red mineral granules — protection from solar radiation and aesthetic harmony with roof tiles
- Thin polyethylene film — when the membrane is covered by tiles or concrete
- Quartz sand — top or bottom coating depending on the installation method
- Woven polypropylene fabric — painted with ESHACRYCOAT or ESHALUMIN
