Shelterbit SBS Cold Climate Membrane

Provides an excellent waterproofing membrane for new

and existing constructions

High flexibility during application at sub-zero tempreture

with no physical strains

Withstands thermal shocks

Proven performance in colder regions

 

ARDEX WPM 191 (Shelterbit Fibrepol SBS) is a high performance Styrene-Butadine-Styrene (S.B.S.) rubber modified bitumen membrane reinforced with a combined reinforcement (polyester and fibreglass).

The exceptional elongation properties of S.B.S. combined with the strength and dimensional stability of the reinforcing provides an excellent waterproofing membrane for new and existing constructions.

ARDEX WPM 191 is coated with either a sanded or talc top surface finish while the bottom surface is embossed and protected by a heat sensitive polythene film. This type of finish for the lower surface has been chosen for two specific purposes.

1. To act as a temperature gauge during application. When the film melts it shows that the compound is at the correct temperature.

2. The embossing is to allow the gases to rapidly escape when heated to its correct installation temperature avoiding possible problems of bubbling and blistering.

 

PRODUCT DESCRIPTION

ARDEX WPM 191 (Shelterbit Fibrepol SBS) is a high

performance Styrene-Butadine-Styrene (S.B.S.) rubber

modified bitumen membrane reinforced with a combined

reinforcement (polyester and fibreglass).

The exceptional elongation properties of S.B.S.

combined with the strength and dimensional stability of

the reinforcing provides an excellent waterproofing

membrane for new and existing constructions.

ARDEX WPM 191 is coated with either a sanded or talc

top surface finish while the bottom surface is embossed

and protected by a heat sensitive polythene film. This

type of finish for the lower surface has been chosen for

two specific purposes.

1. To act as a temperature gauge during application.

When the film melts it shows that the compound is

at the correct temperature.

2. The embossing is to allow the gases to rapidly

escape when heated to its correct installation

temperature avoiding possible problems of bubbling

and blistering.

FEATURES AND BENEFITS

• Positive vapour barrier

• Excellent resistance to atmosphere agents

• High flexibility during application at sub-zero

temperature with no physical strains

• High malleability

• Accommodates structural movements

• Resistant to chemical attacks

• Withstands thermal shocks

• Proven performance in colder regions

• Good elongation and flexibility

USES

ARDEX WPM 191 is used as a single layer or multi-layer

tanking membrane in horizontal or vertical applications

also for waterproofing balconies terraces and flat roofs.

ARDEX WPM 191 membrane is a sandwich membrane

and must be protected from UV radiation.

ARDEX WPM 191 is available in mineral finish for

exposed roof areas.

 

INSTALLATION

The application of ARDEX WPM 191. should be carried

out by an accredited applicator.

Installation shall be strictly in accordance with the

manufacturers recommendations.

Acceptable substrates to which ARDEX WPM 191 is

to be installed must be properly prepared prior to

membrane installation.

All surfaces must be dry clean smooth free of sharp

edges loose or foreign materials oil grease and other

materials which may damage the membrane.

Prior to the application of ARDEX WPM 191 the surface

may require priming with ARDEX WPM 240 (Shelterbit

primer). Coverage of primer will depend on the porosity

of the substrate.

ARDEX WPM 191 is normally fully bonded to the

prepared substrate with side laps of 10cm and end

laps of 15cm overlaps shall be sealed by torch.

ARDEX WPM 191 may be used in various combinations

to produce a variety of specifications tailored to suit the

individual waterproofing need.

The exact specification will depend on functional and

economic requirements. Advice should be sought for

suitable specifications from ARDEX Australia Pty Ltd.

SAFETY PRECAUTIONS

ARDEX WPM 191 is hazardous; non-dangerous goods.

However during installation exercise caution when working

with open flame. Examine all surfaces to which the flame

has been applied for smouldering or burning conditions.

Do not use open flame on or near highly combustible

materials. Follow all local fire codes.

STORAGE

All rolls of ARDEX WPM 191 should be stored in

a covered area protected against sunlight and UV

radiation. Rolls should be stored in a vertical position

on a smooth floor so as not to damage the edges.

PACKAGING

Roll size: 1m x 10m

Roll weight: Approximately 43kg

Rolls per pallet: 23
