“Absorex is designed to control condensation
and corrosion problems on metal and steel
roofs in all climate conditions, including
installations in harsh coastal environments,”
says Lance Woolley, business development
manager, Fibertex South Africa.
“This durable material prevents water
from dripping into buildings causing
damage to furniture, equipment and stored
goods. Absorex also protects against
mould growth and reduces reflective noise
from rain. In addition to protecting the roof
against corrosion and keeping the building’s
contents dry, the polyester layer improves
aesthetics of the ceiling.”
When temperature and humidity of the
roof structure reach dew point, Absorex
applied on the roof panels absorbs moisture
and contains it until conditions are back
above dew point. The moisture is then
released back into the air as vapour.
Absorex is designed for easy application
directly on the roll forming line of the steel
metal at the roof manufacturer, where it
is cut into sheets. This material, which is
resistant to tearing and cutting through, has
a self adhesive coating and a siliconised
foil protection layer which is removed
before application.
There are three different materials in
this range, with various qualities for water
absorption – Absorex 416 09,5 CF 95 g/m

,
Absorex 416 09, 11 CF 110 g/m

and Absorex

.
This range is tested to stringent EN ISO
13501-1 specifications for fire retardancy,
to meet new global standards for fire
resistance, smoke development and burning
Preventing corrosion and condensation
The extensive range of Fibertex geotextiles, which is designed for use in the
construction sector, encompasses Absorex – a non woven material, that
enhances the value of a building and protects its contents by preventing
condensation and limiting corrosion.
The Fibertex range of geotextiles includes
Absorex, which is designed to control
condensation and corrosion problems on
metal and steel roofs in all climate conditions.
This durable material also prevents mould
Cordless impact drill
Like all Makita’s 18V cordless range of tools, the DHP482ZJ Impact Driver
Drill has been engineered using the latest technology.
This model has a protective seal inside
the tool which provides improved water
resistance and dust
protection to the
internal components
– engineered to improve
operation in harsh conditions
(XPT). The twin
LED lights on the front of the
tool provide good illumination
even in dark places, with a
preglow and after-
glow function.
drops. All roof panels applied with Absorex
can be classified B-s1, d0. Absorex is also
fungus tested to EN 14199 method A2 as a
guarantee against mould growth.
Absorex materials are currently produced
at the Fibertex manufacturing facility in
France, with localisation plans in place to
manufacture this range at the Hammarsdale
plant. Fibertex offers support to its extensive
range of woven and non woven geotextiles
with a technical advisory and back up
service throughout Africa.
This model includes the following:
Variable speed, electric brake, reversing,
mechanical 2-speed, keyless chuck, 21
torque settings and is supplied in a
compact systainer case.
The DHP482ZJ is compatible with the
Makita 5 Ah (45 minutes charge time),
3 Ah (22 minutes charge time) and 1,5 Ah
(15 minutes charge time) batteries.
The batteries and
the charger are sold
separately. The
rechargeable and eco-friendly 18V Li-Ion
batteries provide longer run time. The LXT
Li-Ion battery generates an impressive 430%
more lifetime work with two-and-a-half times
more cycles.
