New Zealand Building Code (NZBC)
The product will, if employed in accordance with the supplier's installation and maintenance requirements, assist with meeting the following provisions of the building code:
- Clause B1 Structure: Performance B1.3.1, B1.3.2, B1.3.3, B1.3.3(f), B1.3.3(h), B1.3.3(j), B1.3.4, B1.3.4(a)
B1.3.3 - Frameless glass balustrade adheres with the minimum barrier height in respect to
the location and building type (As per Table 3.1 minimum barrier heights). Stair
barriers in areas likely to be frequently used by children under six years of age
require no gaps larger than 100mm and 150mm in the stair tread. Balustrade
geometry shall follow the dimensions illustrated barriers in figure 3.3 (Example of
barrier geometries).
B1.3.4 - Panorama balustrade style loading aligns with the barrier loads set out in
AS/NZS 1170.1 Clause 3.6 and Table 3.3. The magnitude of the barrier loads that
need to be applied in the design depends specifically on the occupancy of that part of
the building or structure
B1.3.5 - Panorama balustrade style displacement is recommended to not exceed
30mm under barrier and wind loads as described in B1/VM1.
B1.3.7 - Panorama balustrade style fixings and connections are designed to be
suitable for the supporting structure (material and strength), the fixing (type, edge
distance and spacing) and to be adequate to resist balustrade loads.
B1.3.8 - Panorama balustrade has a durability requirement of no less than 15 years.
B1.3.9 - Panorama balustrade style has no sharp edges or projections than can
cause injury when restraining people. All extrusions have minor radii and any sharp
edges are to be removed.
B1.4.3 - Panorama balustrade style uses aluminum that has been designed in
accordance with AS/NZS 1170.0:2002 Appendix B. All product is powder coated or
anodized to the specifiers standards to ensure the best durability of the product in the
installed location. - Clause B2 Durability: Performance B2.3.1, B2.3.1(a), B2.3.2, B2.3.2(a), B2.3.2(b)
B2.3 - Frameless glass balustrade element "Balustrade" must have a durability
requirement of no less than 50 years. - Clause D1 Access routes: Performance D1.3.3, D1.3.3(j), D1.3.3(k)
D1.1.7.1 - Frameless glass balustrade prevents falling from access routes and complies
with NZBC F4 - Clause F2 Hazardous building materials: Performance F2.3.1, F2.3.3(b)
F2.1.1 - Glazing likely subject to human impact shall comply with NZS 4223: Part 3. - Clause F4 Safety from falling: Performance F4.3.1, F4.3.2, F4.3.3, F4.3.4, F4.3.4(a), F4.3.4(b), F4.3.4(c), F4.3.4(d), F4.3.4(e), F4.3.4(f), F4.3.4(g), F4.3.4(h), F4.3.5, F4.3.5(a), F4.3.5(b)
F4.1.1 - Frameless glass balustrade adheres to the minimum barrier heights (F4/AS1 Table
1) in the respective area installed
F4.1.2.1 - Frameless glass balustrade aligns with the barrier height and geometry as set
out in Table 1, Figure 2, figure 3 and figure 4. The barrier design ensures that,
anywhere over the full height of the barrier, a 100 mm diameter sphere cannot pass
through.
F4.1.2.3 - Frameless glass balustrade style shall adhere to the acceptable methods of the construction
of rail barriers in conjunction with parapets so they are not readily available to be
used as seats, as required by Clause F4.3.4(h) for buildings other than housing.
F9.2.1 - The Frameless glass balustrade can be used as a pool barrier when at the
minimum height of 1200mm. Panorama has been design to best relate to Figure 1 (b)
