2 General information
This document provides generic construction details for Cedral Lap façade systems to assist with the design of Cedral Lap façade.
Construction details in this document have been independently certified for the purpose of compliance with Clause E2, External moisture, of the New Zealand Building Code within the scope of E2/VM1.
The weatherproofing performance of any project specific detail or application that is different from or not included in the construction details of this document shall be evaluated by the project engineer or consultant.
It is the responsibility of the project designer, architect and engineer to ensure that the information and construction details provided in this document are appropriate for the intended application.
Cladding support frame and its connection to substructure shall be designed by the project engineer in accordance with the relevant standards. The support frame maximum deflection under the influence of load shall be limited to Span/250.
The support frame, fixings, flashings and the like shall be of adequate corrosion resistance appropriate to the corrosivity category of the project location.
Non-proprietary flashings and capping shall be designed with respect to project wind loading, relevant standards and regulations.
This document is not designed to serve as an installation guide, and is intended to be used in conjunction with other relevant technical and installation documents.
Construction details contained in this document are not to a specific scale, and are for illustration purposes only.
The information in this document is correct at the time of issuing. However, due to our committed program of continuous material and system development we reserve the right to amend or alter the information contained therein without prior notice. Please contact your local Cedral sales organisation to ensure you have the most current version.

3 Ventilated facade
Cedral Lap and Click are designed for a ventilated façade system.
A ventilated façade is a kind of two stage construction, an inner structure with a protective outer skin, and the cladding panel or rainscreen. A ventilated façade consists of an insulated and weathertight structure, a ventilated cavity formed with a cladding support frame, and the cladding panel.
Allowance for adequate ventilation is paramount in ensuring a successful Cedral façade. Ventilated façades provide a number of added benefits to the building and its occupants. These may include but are not limited to the following:
· Positive contribution to energy savings · Minimises thermal bridges · Assists with condensation management · Reduces thermal movement of the structure and cladding support frame · Dissipates radiant heat · Increases acoustic performance of the external wall · Provides an effective drainage path for any moisture passing the cladding skin · Eliminates the need for exposed caulking and sealant, therefore reducing maintenance requirements · Assists with keeping the weather barrier dry and healthy · Provides opportunities for concealing external services such as downpipes within the cavity · Proven to be a more sustainable and healthier façade construction · Architectural design freedom
Air must be allowed to enter the cavity from bottom of the façade, window head, soffit, slab junctions, and the like, and exit from top of the façade, capping, window sill, slab and soffit interfaces, and the like.
All air inlets and outlets shall be protected against entry of birds and vermin into the cavity with a corrosion resistant perforated profile (angle).
The perforated angle should be of maximum 0.9mm in thickness, where placed between the cladding panel and support frame, and be of a minimum 50% open area with aperture size of maximum 3mm to 5mm. The perforations must be kept open and unobstructed to maintain drainage and ventilation of the cavity. The perforated angle shall be positioned to allow an adequate drip edge to the cladding panel.
