            Our product development is focused on minimum environmental impact, and that applies
            very much to Mataki Elastofol. Environment-friendly production aims at preventing
            pollution of water, air or soil.

Alter or extend
             without problems
The ageing-resistant properties of Mataki
Elastofol make it possible to splice new material
to old by hot-air torching, so repairs and exten-
sions in connection with alterations are easily
made. Skylights, lantern lights, pipes and other
fittings can be installed later with no trouble. So
alterations and extensions are not a problem.
   Because Mataki Elastofol is a roofing membrane
with an optimised application system, it can be
laid quickly; if an old roof starts leaking, it can be
repaired without delay. This reduces costs as well
as the risk of damage caused by damp, which
could interfere with production in industry or
make it necessary to evacuate tenants.

Minimum maintenance
The ability of Mataki Elastofol to resist weather,
wind, mechanical stresses, movement, UV radia-
tion and thermo-oxidative degradation minimises
the need for maintenance.
   Mataki Elastofol is a technically advanced system
compared to many other roofing systems, which
often require regular inspection.
   Mataki Elastofol is the closest you can get to a
maintenance-free roof.

                                                         The excellent splicing properties of Mataki Elastofol
                                                         make it easy to repair or extend, even where the material
                                                         is old. Alterations to roofs need no longer be a headache.

             by roofing contractors

Studies indicate that most cases of damage
to roofs are caused by faulty installation, which
can often be blamed on non-user-friendly systems
or materials. The unique properties of Mataki
Elastofol, with its safe and flexible splicing sys-
tem, eliminate such problems.                            Mataki Elastofol is secured with mechanical fasten-
