Barrel Vault/Chisholm College, Bedford, Perth Western Australia

This project was finished recently, and this will help you understand the benefits of our system.

You will be able to see how quick the installation process is with our 74mm polycarbonate system, and how construction time is dramatically reduced. Installation time on this project was 8 hours, and three tradesmen were available on site.

Everbright E610 Opal was installed at Chisholm College over the D Block Building. Everbright E610 was extruded and supplied in 2.7mtr curved panels and in 600mm configurations. Our panels simply clip together, making the installation process rapid, as our product only requires to be joined every 600mm on site. E610 free spanned 2.5mtr, incorporating Locking System 1. Locking system 1 simply means there are 6 polycarbonate locking bars required out of every 6 chambers. See design loads, which shows you in more detail the different locking systems available.

The total area was 86.4sqm, the curved panel length was 2.7mtr x 32mtr.

The design brief was for a translucent roof that was fully trafficable, should anybody from the college access the roof. Our product was selected due E610's superior panel strength and this offered additional protection. E610 polycarbonate panels incorporate an excellent safety factor. All loading criteria are based on 0.75kN/sqm and a 50% safety factor as part of a standard specification detailing.

Our system was also selected in order to provide weather protection over this entire area, while maintaining the ambient light. Another factor for the selection of E610 was it's thermal capabilities that dramatically keeps heat levels down. The product also has great appeal due to it's modern appearance, self cleaning dome shape profile and long life expectancy.

Since less structure is required with our system less shadows are created, and as such the natural light translucency is at it's full potential. On this project there was a requirement for a 300mm over hang and E610 panels also incorporate a 75mm drip nose. This is manufactured as standard on the sheets in the factory at either end for barrel vault roofs. The drip nose is incorporated into the top layer of our polycarbonate panels thus keeping the roof 100% weather tight.

Our polycarbonate system give a seamless and continuous line, with no steel frame work spoiling the visual effect. E610 Integral locking bars hide the aspect of where a panel starts and where it finishes, so it becomes a continuous system giving a uniformed and conformed design feature. Creating an architectural flare, that isn't possible with any other polycarbonate system available on the market. Other systems would necessitate the need for a framed grid work support system across the entire roof. On this project our system only needed to be secured to both sides of the eaves structure, all the joints are self sealing once the integral locking bar is fitted.

E610 is a very light weight product, that can be easily manoeuvred on site during the installation process.

The construction process with E610 is very simple and is less time consuming to install on site. We can advise that there was a significant cost saving on the structure requirements with our system on this project.
