- Suitable for use on buildings over 3.5m in height
Conditions of use
Hercules Cedarboard can be only be used when installed:
- in a horizontal orientation
- on vertical surfaces
- over a cavity
Hercules Cedarboard:
- must be used with joinery meeting the requirements of NZS 4211 for the relevant wind zone
- design details must be in accordance with the Hercules Cedarboard Design Manual (Version 2)
- all installation must be done by a Licensed Building Practitioner (LBP) even if Restricted Building Work is not applicable under the Building Act 2004
Relevant building code clauses
B1 Structure — B1.3.1, B1.3.2, B1.3.3 (f, h, m), B1.3.4
B2 Durability — B2.3.1 (b)
C3 Fire affecting areas beyond the fire source — C3.5, C3.6, C3.7
E2 External moisture — E2.3.2, E2.3.5, E2.3.7
F2 Hazardous building materials — F2.3.1
Contributions to compliance
B1 Structure: Hercules Cedarboard complies with B1 structure and the relevant code clause by virtue of the fact that the weatherboards are fixed through the wall underlay to the framing in accordance with Table 24 of E2/AS1.
B2 Durability: Hercules Cedarboard as Western Red Cedar is treated to Hazard Class 3.2 in accordance with NZS 3602:2003 and NZS 3640:2003 which allows it to be used uncoated or stained for 15 years.
C3 Fire affecting areas beyond the fire Source: Hercules Cedarboard was tested to the requirements of National Fire Protection Association (NFPA) 285 by a Telarc registered test facility.
E2 External Moisture: Hercules Cedarboard complies with the requirements of E2/AS1 applied to a risk score of 12 over a 20 mm cavity and testing to E2/VM1 has provided evidence of its use over a 20 mm cavity up to a risk score of 25.
F2 Hazardous Building Materials: Hercules Cedarboard contains no quantities of gas, liquid, radiation or solid particles which can be emitted that give rise to harmful concentrations at the surface of the material where the material is exposed, or in the atmosphere of any space.

Building code performance clauses
B1 Structure
B1.3.1
Buildings, building elements and sitework shall have a low probability of rupturing, becoming unstable, losing equilibrium, or collapsing during construction or alteration and throughout their lives.
B1.3.2
Buildings, building elements and sitework shall have a low probability of causing loss of amenity through undue deformation, vibratory response, degradation, or other physical characteristics throughout their lives, or during construction or alteration when the building is in use.
B1.3.3
Account shall be taken of all physical conditions likely to affect the stability of buildings, building elements and sitework, including:
- (f) earthquake
- (h) wind
- (m) differential movement
B1.3.4
Due allowances shall be made for:
- the consequences of failure,
- the intended use of the building,
- effects of uncertainties resulting from construction activities, or the sequence in which construction activities occur,
- variation in the properties of materials and the characteristics of the site, and
- accuracy limitations inherent in the methods used to predict the stability of buildings
B2 Durability
B2.3.1
Building elements must, with only normal maintenance, continue to satisfy the performance requirements of this code for the lesser of the specified intended life of the building, if stated, or:
- (b) 15 years if: those building elements (including the building envelope, exposed plumbing in the subfloor space, and in-built chimneys and flues) are moderately difficult to access or replace, or failure of those building elements to comply with the building code would go undetected during normal use of the building, but would be easily detected during normal maintenance.
C3 Fire affecting areas beyond the fire source
C3.5
Buildings must be designed and constructed so that fire does not spread more than 3.5 m vertically from the fire source over the external cladding of multi-level buildings.
C3.6
Buildings must be designed and constructed so that in the event of fire in the building the received radiation at the relevant boundary of the property does not exceed 30 kW/m² and at a distance of 1 m beyond the relevant boundary of the property does not exceed 16 kW/m².
C3.7
External walls of buildings that are located closer than 1m to the relevant boundary of the property on which the building stands must either:
- be constructed from materials which are not combustible building materials, or
- for buildings in importance levels 3 and 4, be constructed from materials that, when subjected to a radiant flux of 30 kW/m², do not ignite for 30 minutes, or
- for buildings in Importance Levels 1 and 2, be constructed from materials that, when subjected to a radiant flux of 30 kW/m², do not ignite for 15 minutes.
E2 External moisture
E2.3.2
Roofs and exterior walls must prevent the penetration of water that could cause undue dampness, damage to building elements, or both.
E2.3.5
Concealed spaces and cavities in buildings must be constructed in a way that prevents external moisture being accumulated or transferred and causing condensation, fungal growth, or the degradation of building elements.
E2.3.7
Building elements must be constructed in a way that makes due allowance for the following:
- the consequences of failure:
- the effects of uncertainties resulting from construction or from the sequence in which different aspects of construction occur:
- variation in the properties of materials and in the characteristics of the site.
F2 Hazardous building materials
F2.3.1
The quantities of gas, liquid, radiation or solid particles emitted by materials used in the construction of buildings, shall not give rise to harmful concentrations at the surface of the material where the material is exposed, or in the atmosphere of any space.
