(a) Statement of Building Code Compliance
NZBC Compliance
Test information available from Pacific Coilcoaters and BHP NZ Steel, and past history of fascia systems, indicate that provided the product use and maintenance is in line with the guidelines contained in the current literature referenced, Dimond Rainwater Disposal Systems can be expected to meet the performance criteria in clause E2 of the New Zealand Building Code, for a period of not less than 5 years.
Use Outside the Stated Guidelines
If the need arises to use Dimond Rainwater Disposal Systems outside the limitations and procedures given in this or other referenced literature, or, if any doubt exists on product handling or use, written approval for use must be obtained from Dimond, before the project commences.
(b) Scope of Use
Dimond Fascia 147 and 185 are coated steel fascia systems intended for use as fascia and barge boards to support gutter systems, covering roof truss ends and gable ends around the roof perimeter on timber trussed residential buildings. External gutters are then fixed directly to the fascia to allow collection and discharge of rainwater.
Suitable for use with longrun metal roofing, metal tiles or concrete tiled roofs. Reference should be made to the Environments section, to ensure the correct coated material on the fascia is chosen for the environment.
Dimond do not recommend fascia systems are used in very severe marine or geothermal environments as fascia is not available in plain aluminium, AR8, ARX, stainless steel or copper.
Typically 185 panel is used up the gable ends while 147 panel is used along the front.
(c) Consenting Instructions
Metal fascia systems have been used successfully on timber trussed residential buildings for the last 20 years.
For consenting it is important to check the correct prepainted finish has been selected for the environment.
The gutter size should be chosen for its water carrying capacity and should ensure the size of the bracket and gutter can physically fit the panel depth.
