Kerto LVL Q-panels and S-beams
The new Macallan Distillery and Visitor Experience in Craigellachie, Speyside in Scotland is a stunning sight. From above on the hillside you see five domes, resting under a living meadow roof, as you get closer the unique undulating wooden roof structure is revealed.
The contemporary building combines an undulating wooden roof with glass and steel. Light and green Kerto LVL (laminated veneer lumber) is part of the roof, which was fully prefabricated.
Kerto LVL Q-panels and S-beams are used as cheeks on both sides of the glulam beams and Q-panels in the roof decks. Kerto LVL S-beams can also be found outside on the service road.
“Kerto LVL S-beams and Q-panels are an integral part of the structure of each beam, because they contribute to the overall dimensions. Every beam has the same dimension. We also achieve a contemporary aesthetic by using Kerto LVL, which has an omnidirectional surface,” says Toby Jeavons, Project Architect at Rogers Stirk Harbour + Partners, a renowned international architectural practice responsible for the architecture.
The wooden parts were CNC machined and assembled at the Wiehag factory in Austria. The Kerto Q-panels and S-beams had high non-standard requirements.
“All Q-panels and S-beams arrived on time, and their quality and specifications were fully met. The Q-panels, for example, had to be very thin, with a sanded surface,” says Johannes Rebhahn, Sales Director International Timber Projects at Wiehag, who was responsible for the engineered wooden roof construction.
It was easy to add Kerto LVL to both sides of the glulam beams, because LVL has great workability while being a very strong and rigid material. It doesn’t warp or twist over time.
“Kerto LVL is a very good engineered wood material, because you can trust the material dimensions. In general, offsite construction is a great way to save construction time. When prefabrication such as cutting is done in the factory, and connections have been designed to be simple, the easier, safer and more cost-effective life on site is,” says Rebhahn.
The construction of the Macallan Distillery and Visitor Experience took only six months. It was a carefully coordinated operation and the roof contains some 3,600 beams and 2,500 roof panels.
