Description

Danosa Torch-on Roof Waterproofing Membrane is a waterproofing membrane for nominally flat, pitched and curved roofs, gutters and parapets. It is installed as a multi-layer system with a mineral chip finish.

The product is supplied as a torch-on, reinforced, polymer-modified bitumen sheet in roll form.

Scope

Danosa Torch-on Roof Waterproofing Membrane has been appraised as a roof waterproofing membrane 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 supporting structures of timber framing with substrates of plywood; and,
  • with substrates of suspended concrete slabs; and,
  • situated in NZS 3604 Wind Zones, up to, and including Extra High'.

Danosa Torch-on Roof Waterproofing Membrane has also been appraised for use as a roof waterproofing membrane on specifically designed buildings within the following scope:

  • with building structures designed and constructed to comply with the NZBC; and,
  • with roof supporting structures of timber framing with substrates of plywood; and,
  • with substrates of suspended concrete slab; and, subjected to maximum wind pressures; 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 waterproofed with Danosa Torch-on Roof Waterproofing Membranes must be designed and constructed in accordance with the following limitations:

  • nominally flat, curved or pitched roofs constructed to drain water to gutters and drainage outlets complying with the NZBC; and,
  • constructed to suitable falls; and,
  • with no integral roof gardens.

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 the Appraisal.
