| Description of roofing membrane: |
|
Breawarf roofing membrane is thermal
laminated by the high polymer material in
the middle layer . Paving on the top of
the insulation system, it can strengthen the
water tightness of the building, as well
as to eliminate humidity inside the
containment by the unique breath ability,
thus to retain the duration of
building effectively , playing a part
in thermal insulation, energy
conservation and living environmental
improvement.

| Building up principle of roofing
membrane: |
| Breawarf
roofing
membrane, thermal laminated by high polymer
material + polyolef in microporous membrane + high
polymer material, we create this technology in
China which is advanced all over
the world. Polyolefin microporous membrane
has excellent breathability, as well as good
duration. Polyolefin microporous membrane has not
only acid and alkali resistance, but also good
extensibility which enable the fasresilience after
tearing by nail so that to improve the
sealing performance.

| Operating principle: |
|
There are two kinds of operation principle
for breath: microspore and
hydrophilic group. Breawarf roofing membrane
adopt the principle of microspore. The
minimum diameter of water drop is
about 20 micron while the diameter of water vapour molecule is about 0.0004 micron, because of
the enormous difference, water vapour can get
across according to the dif fusibility,
while water molecule can't pass because of
the surface tension. As a
result, the roofing membrane can prevent
osmotic water , so that to have the water
proof function.

| Characteristics of roofing membrane: |
A Excellent Performance at water resistance
B Particular function of vapour
permeability, so called roofing membrane
C Good performance at UV
resistance
D Tear resistance, wear
resistance, good extensibility.
E Light and thin,
antiskid, with good low temperature flexibility,
suitable for construction in different
condition.
F The 100% recyclable polymer materials,
fit the ecologist
requirements. |

| Function of roofing membrane: |
Air-tightness
of Breawarf roofing membrane
Breawarf roofing membrane
paves outside of the insulation system, wrap
up the whole building, can strengthen
air-tightness effectively and reduce air
leak as well as convectional heat loss.
Water tightness of Breawarf roofing membrane
Thanks to the prominent
water proof performance, Breawarf roofing
membrane can wrap building tightly , protect
the building from corrosion of water vapour
and rain. Guarantee good insulat ion
performance and well durability of building,
enable the building to be more energy
conservation and environmental protection.
Permeability of Breawarf roofing membrane
Breawarf roofing
membrane paves outside of the insulation
system, enable the water vapour inside the
insulation system to exhaust, solve the
condensation problem, protect the insulation
system.When condensation appears because of
the temperature difference, the water drop
will forming at the top of roof or surface
of wall, incursion of such water drop into
the insulation system will result in the
lower thermal efficacy and shorter duration
of building. After pave Breawarf roofing
membrane, water vapour will exhaust easily .
The water drop condensate inside the roofing
tiles will drop to the Breawarf roofing
membrane, flow away from the drain tank.
Reduce construction
cost
Breawarf roofing membrane can protect the insulation system,
saving the fine concrete or the film
waterproofing materials which regularly
paved on top of insulation system so
that to reduce theconstruction cost. |

| Application of roofing membrane |
|
Mainly used as underlay for pitched roof and
enclosure protection for insulating layer of
walls. |
