Overview

Heritage Tray® Performance



Evolving from the already popular and stylish Eurotray® family, Heritage Tray® markets itself as an elegant, economical and flexible roofing profile. Additionally, it can be roll-formed on-site, an attractive logistics option for larger construction projects.

*Vented underlay (Tyvek Metal or Dimond approved equivalent) laid full cover over purlins (or laid full cover over the face of cavity battens for walling) is required in all Wind Zones. In addition, Plywood substrate is required in Extra High and Specific Engineering Design (SED) Wind Zones.

**Refer to the NZMRM Code of Practice:12.1.3A Roof Noise caused by timber shrinkage, to reduce the risk of noise and other potential problems such as shrinking, warping, or deformation after roofing installation, ensure that the timber substrate has a moisture content within the range of 12% to 15%. Use a moisture meter to measure the actual moisture content and allow the timber to acclimate to the local climate

***Contact Dimond Roofing on 0800 ROOFSPEC for specific advice on product suitability for your location.

Sheet lengths:
Heritage Tray is custom run to order.


Where long sheets are used, consideration must be given to:

  • Special transportation licences
  • Should be run on-site
  • Site access for special lifting equipment
  • Fixing techniques to accommodate thermal expansion


This roofing system is to be installed by a RoofingSmiths or a Dimond Recommended Installer.


***NOTE:

  • Photovoltaic laminates (PVL’s) can be installed on to this profile at an additional cost when the cladding is completed and other trades have finished or it can be installed at a later date
  • Laminates are 348mm wide and available in 5.910mm and 2.585mm lengths with a lead time of 16 weeks
  • Laminates cannot be installed on raking sections of roofs
  • Consult with Dimond Roofing for further information
  • The Dimond Roofing Heritage Tray profile is only available in a fixed cover width, and cannot be manually folded. When the profile is used as wall cladding, careful attention is required to sheet set-out and sheet width tolerances to ensure the sheet modules align to wall openings.

SOUND REVERBERATION

Extreme wind events may cause sound reverberation on Heritage Tray pans. It does not cause detriment to product performance.


OIL CANNING


Oil Canning is the visible waviness in the flat areas of metal roofing and walling. Oil canning produces an aesthetic effect inherent in standing seam tray profiles and profiles/flashings with wide flat elements. It does not cause detriment to product performance.


Oil canning can occur during the forming and installation processes and during thermal expansion of the roof sheeting during its life cycle. The effect can be more or less pronounced depending on differing light and sun angle conditions and the coating gloss levels.


For Heritage Tray, oil canning can be reduced by the vented roof underlay (e.g. Tyvek Metal). There are several options to reduce the oil canning effect in tray-type profiles and flashings, for example:

a) increasing the thickness of the material,

b) using stiffening swages in wide flat elements and

c) limiting flat elements to less than 150mm width.


For further information, please refer to the New Zealand Metal Roof and Wall Cladding Code of Practice, Section 12.3.

Notes
  1. For Non-Access / Roof - Purlins are required to be at maximum 500mm spacing
  2. Category 1 maximum spans are based on static point load testing as a guide, and further limited by practical experience of roof performance under dynamic foot traffic loads. Category 3 maximum spans are limited as a guide to achieving a satisfactory appearance for wall cladding. Loads given are based on 2 screw fasteners per clip
  3. Loads given are based on 1 clip/sheet/purlin. Refer Fastener Layout Options
  4. Loads given are limited to a maximum of 4.7kPa. If design requirements exceed this limit, Contact Dimond Roofing for specific advice.
  5. End span capacities given in this table are based on the end span being the same as the internal span.
  6. Design Criteria for Limit State Capacities
    1. Ultimate Limit State
      No pull through of fixings or fasteners withdrawal resulting in sheet detachment due to wind up-lift (outward) loads.
  7. System Design
    The span capacity of Heritage Tray is determined from the Heritage Tray Limit State Load/Capacity Chart using the section of the chart appropriate to grade and type of material and to the category of serviceability selected from the two categories below. It is recommended that to obtain a dependable design strength capacity for the ultimate limit state, a reduction factor of Ø = 0.8 is applied.

    The capacities given do not apply for cyclone wind conditions.

    Serviceability Requirements

    While these categories are given for design guidance to meet the serviceability limit state criteria, foot traffic point load damage may still occur if there is careless placement of these point loads.

    Unrestricted-access roof

    Expected regular foot traffic to access the roof for maintenance work and able to walk anywhere on the roof. No congregation of foot traffic expected.

  8. Wind Pressure Guide
    As a guide for non-specific design the following S.L.S. design loads in accordance with the MRM Roofing Code of Practice can be used for buildings less than 10m high, otherwise, AS/NZS 1170.2 should be used

    Low wind zone = 0.68kPa, Medium wind zone = 0.93kPa, High wind zone = 1.32kPa, Very high wind zone = 1.72kPa and Extra high wind zone = 2.09kPa.
Fastener Design

Heritage Tray®Fastener Design



Fasteners that are used to secure Heritage Tray clip down as a roof cladding must penetrate into the purlin a minimum of 30mm for timber and 6mm for steel purlins. For wall cladding, the clip fasteners must be long enough to pass through the substrate, cavity batten and into the main frame by 30mm for timber and 6mm for steel.

If cavity batten and/or insulation is used over the purlins the screw length will need to be increased by at least the cavity batten and/or insulation thickness.
