2.7mm APP Bitumen Fibre Backed Base Sheet Excellent elongation 60% at break Cold Flexibility to -5?C Excellent resistance to pollutants
PRODUCT DESCRIPTION ARDEX WPM 116 (Shelterbit F.B. Base Sheet) is an A.P.P. (Atactic Polypropylene Plastomeric) type modified bitumen membrane slip or base sheet consisting of a specially formulated bituminous compound of distilled asphalt modified with selected high grade visco-elastic polymers. The product is reinforced with a combination of fibreglass and non-woven polyester. ARDEX WPM 116 top surface is embossed and protected by a heat senstive polythene film. This type of finish for the top 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 due to gases being trapped between the slip or base sheet and the membrane subsequently applied on top. The lower surface of the slip or base sheet is an uncoated non-woven polyester matt.
PHYSICAL AND CHEMICAL PROPERTIES A.P.P. modified compound Excellent elongation Cold flexibility -5?C Excellent resistance to pollutants Good elastic memory Good mechanical characteristics Good dimensional stability Good puncture resistance Will not decay Good elongation USES ARDEX WPM 116 is always installed as a base sheet in multi-layer systems either loose laid mechanically fastened (using large headed roofing fasteners under overlap area) or fully adhered with ARDEX WPM 245 Adhesive (Shelterbit Fibre Back Adhesive). ARDEX WPM 116 has been specifically designed for applications to heat sensitive substrates such as wooden decks or thermal insulation. Also can be installed as a base-layer on rough or un-even concrete decks. Overlaps are not normally torched sealed unless ARDEX WPM 116 is to be used as a vapour control layer or as a secondary-waterproofing layer.
INSTALLATION The application of ARDEX WPM 116 should be carried out by an accredited applicator. Installation shall be strictly in accordance with the manufacturers recommendations. Acceptable substrates to which ARDEX WPM 116 is to be installed must be properly prepared prior to membrane installation. ARDEX WPM 116 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 116 is hazardous; non-dangerous goods. 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 such as wet adhesive. Follow all local fire codes. STORAGE All rolls of ARDEX WPM 116 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: 1.05m x 10m (Fleece is 1.0m wide leaving 50mm selvedge for lap bonding).
Roll weight: Approximately 30kg.
Rolls per pallet: 30
