FAQ Click each question to reveal the answer.

Q. What are Tridek Contemporary Roofing Panels?
A. The Tridek Contemporary Roofing Panel is a customised structural roofing panel designed as an alternative to standard roofing methods. Tridek Panels are manufactured by bonding profiled roof sheeting to the top and bottom of an expanded polystyrene core, to give a composite roof and ceiling panel. To ensure a maximum surface area bond, the foam core is profiled to suit the metal skin. Tridek roofing panels are available in straight, curved and wave or multi-curved panels.
Q. How far can a Tridek panel span?
A. While outcomes vary according to a number of design factors (including wind loads etc.),it is generally the case that a 140mm panel will span up to 8.000m in a N2 W33 region. We have panels that can span up to 10.300m and carry substantial roof loads.
Q. Can a Tridek panel support solar panels and other mechanical unit loads?
A. Yes. In most cases solar panels, air-conditioning and hot water units etc. can be mounted on a Tridek roof. However in the case of extremely heavy loads we recommend that you consult with us directly, as in some cases in may be prudent to place a heavy load over an internal beam or wall.
Q. Can I cut a penetration through the panel?
A. Penetrations are cut as you would any panel roof: cut to top and bottom skins, core foam out, place flue or pipe, seal opening after placing flue or pipe and finish with an appropriate flashing.
Q. Can Safety Anchor points be installed?
A. Safety Anchors are installed to manufacturer's specification by fixing with appropriate fastenings to the top skin
Q. Can lighting and fan fixtures be installed in a Tridek roof?
A. A concealed service core is provided at each panel joint. Fans are fixed using a Tridek fan mounting block. Down lights, surface mounted lights or suspended light fittings can be fit easily, as can fans, air conditioning ducting and suspended ceilings.
Q. Can a suspended ceiling or service duct track be supported from the roof?
A. Yes, furring channels or battens can be fixed directly to the underside of the panel skin.
Q. By what method are the roofing panels fixed together?
A. Each panel is fixed at every 2nd rib with 14g, type 17 roofing screws, fitted with cyclone washers. The panels can be directly fixed to either timber or steel structure. A minimum of 50mm MGP10 pine is required for a timber structure, and, subject to engineer�s design between 2mm and 5mm is required for a steel structure.
Q. What is the standard width and length of a Tridek Contemporary Roofing Panel?
A. Tridek's series of roofing panels, depending on the profile selected, range from 650mm of effective cover to 762mm (the same as a standard sheet of corrugated sheeting). If required, panels can be cut during installation to achieve any width required.

Tridek panels can be manufactured up to 16m in length, longer lengths by negotiation. The Pro series panel has a cover of 762mm, the Smart series a cover of 700mm, and the Elite series a cover of 650mm. Cantilevers can be achieved to a maximum length of 25% of the back span (for example, an 8.000m panel span, could cantilever 2.000m). It is recommended that you discuss with Tridek staff your proposed cantilever span.
Q. How far can the Tridek Contemporary Roofing Panel span?
A. The maximum span of a Tridek Panel varies according to the thickness of the panel. The 140mm panel is capable of spanning up to 8 metres unsupported, depending on wind load requirements. Spans for other thicknesses of panels and wind loads can be found in our technical information.
Q. What is the maximum allowable overhang for eaves?
A. In length, the roof can achieve a standard cantilever of up to 1 metre. This can often be extended further in consultation with Tridek, through the utilisation of our engineering facilities. In width, the roof can have a maximum unsupported overhang of 300mm. Greater distances are achievable with the use of outriggers.
Q. Can the underside sheet be flat?
A. The use of a flat surface for the underside sheet affects the structural integrity of the panel, and therefore is not an option we currently offer with our panels.
Q. What materials can be used?
A. Aluminium and steel (pre-coloured, galvanized and stainless) can all be used as either the top or bottom sheet of a TRIDEK Contemporary Roofing Panel.
Q. Can I have a different colour for the top and bottom sheet?
A. Yes, the colours of both top and bottom sheets can each be customised independently of the other.
Q. Are there allowances for higher wind classes with the TRIDEK Contemporary
    Roofing Panel?
A. The higher the wind class or rating, the smaller the permissible span. More specific details can be found in our technical information. Panels suitable for cyclonic areas are available.
Q. Can the panels be used as a wall cladding?
A. Yes. The panels are quite versatile and have been used for various recent projects as a wall cladding.
Q. What is your lead-time?
A. We have an approximate lead-time of 3-6 weeks. However, where required, and within the bounds of our manufacturing schedule, we are happy to work with you to determine if and where the process of manufacture can be accelerated to help meet your construction deadlines.
