Shelterbit Mineral Membrane

4.5kg/m2 Mineral Coated APP Bitumen Membrane

Excellent resistance to atmospheric agents

Resistant to chemical attacks

High puncture resistance

 

ARDEX WPM 185 (Shelterbit Mineral) is an A.P.P. (Atactic Polypropylene Plastomeric) type modified bitumen membrane consisting of a specially formulated bituminous compound of distilled asphalt modified with selected high grade visco-elastic polymers and reinforced with a combined reinforcement (Polyester and Fibreglass).

ARDEX WPM 185 is coated with a slate mineral granule topping 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 atmospheric agents

• Cold flexibility -5?C

• Excellent elongation

• Resistant to chemical attacks

• Withstand thermal shocks

• Heat welded laps provide homogenous joint

• Prefabricated membrane

• High puncture resistance

USES

ARDEX WPM 185 is used as a cap layer in exposed

membrane systems (allowing light foot traffic for

maintenance).

ARDEX WPM 185 is available in slate grey green

and white

INSTALLATION

The application of ARDEX WPM 185 should be carried

out by an accredited applicator.

Installation shall be strictly in accordance with the

manufacturer’s recommendations.

Acceptable substrates to which ARDEX WPM 185 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.

ARDEX WPM 185 is normally installed in a multi-layer

system incorporating ARDEX Bitumen membranes or

base sheets.

ARDEX WPM 185 is fully bonded to plan or base layer.

Overlaps are always torch-bonded with a width of 10cm.

The exact specification will depend on functional and

economic requirements. Advice should be sought for

suitable specification from ARDEX Australia Pty Ltd.

SAFETY PRECAUTIONS

ARDEX WPM 185 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 185 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 45kg

Rolls per pallet: 20
