Description

Novaflex and Polibit Roof and Deck Waterproofing Membranes are waterproofing membranes for nominally flat, pitched and curved roofs, gutters, parapets and decks.

The products are installed as double layer systems on roofs with mineral chip finish and protected by a raised deck system.  On concrete roofs and decks the products are installed as a single layer and protected by paving slabs or screed.

The products are supplied as torch-on, reinforced, polymer-modified bitumen sheets in roll form.

Scope

Novaflex and Polibit Roof and Deck Waterproofing Membranes have been appraised as roof and deck waterproofing membranes on buildings within the following scope:

  • the scope limitations of NZBC Acceptable Solution E2/AS1, Paragraph 1.1 with respect to building height and maximum floor plan areas; and,
  • with building structures designed and constructed to meet the requirements of the NZBC; and,
  • with roof and deck supporting structures of timber framing with substrates of plywood or fibre cement sheet; and,
  • with substrates of suspended concrete slabs; and,
  • situated in NZS 3604 Wind Zones, up to, and including Extra High'; and,
  • with decks that have a maximum area of 40 m(refer to Paragraph 7.4).

Novaflex and Polibit Roof and Deck Waterproofing Membranes have also been appraised for use as roof and deck waterproofing membranes on specifically designed buildings within the following scope:

  • with building structures designed and constructed to comply with the NZBC; and,
  • with roof and deck supporting structures of timber framing with substrates of plywood or fibre cement sheet; and,
  • with substrates of suspended concrete slab; and,
  • subjected to maximum wind pressures (Refer Paragraph 8.1); and,
  • with the weathertightness design of all junctions being the subject of specific design by the designer.

Note: The design of these junctions has not been appraised by BRANZ and is outside the scope of the Appraisal.

Roofs and decks waterproofed with Novaflex and Polibit Roof and Deck Waterproofing Membranes must be designed and constructed in accordance with the following limitations:

  • nominally flat, curved or pitched roofs and decks constructed to drain water to gutters and drainage outlets complying with the NZBC; and,
  • constructed to suitable falls; and,
  • with no integral roof gardens; and,
  • no steps in level within the deck area, except into gutters; and,
  • no downpipes direct discharge to decks; and,
  • with membranes protected from physical damage or UV light by ceramic or stone tile finishes or timber, resting on approved pedestal support system.

The design and construction of the substrate and movement and control joints is specific to each building, and therefore is the responsibility of the building designer and building contractor and is outside the scope of this Appraisal.

The membranes must be installed by Jaydex International Ltd Licensed and Trained Installers.
