Introducing
the EVALON® Membrane system
EVALON®, due to it's unique formulation, is virtually
plasticer-free and offers superior performance with regard to
strength, elongation, dimensional stability, long term flexibility,
weathering and chemical resistance. Membranes are available
in unbacked or fleecebacked sheets, in a number of colours and
can be fully adhered, loose-laid and ballasted or mechanically-fixed.
The Evalon® roofing system has the following:
Chemical Resistance
EVALON® also has a substantial track record as a
pond lining and tanking membrane, making it the ideal choice
for "Green Roofs" (roof gardens).
Vapour Permeability
A useful feature of EVALON® is the possibility
of releasing moisture vapour through the waterproofing layer
into the atmosphere.
This is even more important in buildings with high internal
humidity and/or temperature, such as swimming pools, laundries,
and buildings accommodating certain kinds of manufacturing processes.
Fire Resistance
EVALON-FR achieves an Ext. F.AA Rating in accordance with
BS 476: Part 3: 1958, without protective covering (laid on PIR
insulation on steel decking).
Flexural Fatigue Resistance
Another very important factor in evaluating a roofing system
is the flexural fatigue resistance of the waterproofing. This
is of particular interest in lightweight roof constructions
with increased potential movement (wind, vibration, thermal
movement).
Resistance to Weathering / UV
EVALON® membranes have superior weather resistance in
comparison with other roofing materials. This is mainly due
to the fact that EVALON® only contains proven constituents
such as EVA-Terpolymer and PVC
Expected Service Life
ALWITRA GmbH & Co. has manufactured and marketed PVC and
EVA membranes for over 25 years in Europe and overseas. EVALON®
is thge result of continuos research and development in cooperation
with DuPont de Nemours, one of the world's largest chemical
corporations and specialists in plastics. All our experience
