With the introduction of a new BRANZ-appraised batten cap roofing system, known as Quick Batten Tray or QBT 450™, the roofing sector is about to change. Lifting the lid on products and systems that have traditionally been used in New Zealand, QBT 450™ is a system that allows for significant cost savings to a Batten Cap type profile, and a range of unique, striking finishes.
Batten cap roofing creates a dramatic aesthetic and has been particularly popular in the South Island where homes often allude to the gabled vernacular in form. “Batten cap roofing is particularly suited to this sort of design but it makes a bold statement in all sorts of designs,” The Architectural Roofing Company’s Bruce Gibson says.
Standard batten cap roofing systems require solid plywood sarking substrates, which adds a significant amount to the cost of installing a batten cap roof. The QBT 450™ system was designed to be installed directly over open purlins, reducing cost by removing the need for a plywood substrate, and also in terms of labour being able to be installed much more efficiently.
“Normally too, with batten cap roofing, you lay the trays down and then put the caps on top. What is different about QBT 450™ is that this profile has the cap and tray all in one piece reducing installation time even further,” Bruce says.
