Bituminous Membrane NEOFLEX S4180
SBS Modified Bituminous Membrane
Polymer (SBS) modified bituminous membrane, reinforced with non-woven polyester mat.
The Polyester combines high tensile strength with an elongation above 50%. A high performance elastomeric waterproofing membrane which combines that ability to withstand high ambient temperature with the usual characteristics of an SBS membrane of high flexibility at low temperature that makes it easy to apply at sub-zero temperature.
ADVANTAGES
- Cold flexibility
- Heat stability
- Thermal ageing resistance
- UV resistance
- Resistance to foot traffic
SURFACE FINISH
It is covered either with polyethylene film or sand at the back
and comes in a variety of surface finishes; sand, polyethylene
film, slated or aluminium. The slate can be natural grey,
white, black or green or any other colour depending on
stock availability.
THICKNESS, ROLL SIZE & PACKING
It is produced 4mm thick in rolls of 1 × 10 meters. The rolls
are palletized and shrink wrapped.
SPECIAL FEATURES
- Positive vapour barrier
- Excellent resistance to atmospheric agents.
- High flexibility during application at sub-zero
temperature with no physical strains
- High malleability making it entirely suitable for difficult
basement and foundation works.
- High softening point allowing it to maintain shape
stability at high temperatures.
- Withstands thermal shocks.
- Accommodates structural movements.
- Resistant to chemical attacks.
APPLICATION INSTRUCTIONS
The membrane must be unrolled and laid down on the area
to which it is to be applied. Check the orientation carefully.
Adjacent rolls should then be laid, each overlapping the one
next to it by 10cms on the side and 15 cms at the ends.
Taking care not to change to orientation of each roll, reverse
the process until each has been re-rolled. When laying the
roll, the lower surface should be heated with a propane
torch, using sweeping left to right movements. This will melt
the lower surface to the membrane and allow it to stick to
the substrate. On slated membranes you should either
remove the special selvedge paper or on sand bottom rolls
torch the special polypropylene selvedge. Continue this
process for each subsequent roll, remembering that the
overlaps must be 10cms for the edges and 15cms at the
ends. When the process is complete, carry out an inspection
to ensure total adhesion.
STORAGE & MATERIAL HANDLING
The rolls should always be stored vertically in a shaded area.
Normally the pallets should not be stacked one over the
other. However, if a wooded board is used in between, two
pallets may be stacked one over the other.
