COMING SOON!

With a sleek minimalist design that sits perfectly flush with S1’s rafter bars, and using powered actuators that can be intelligently automated, the S1 has reimagined roof vents, bringing them into the 21st century at last. Dispensing with the need for muntin bars, SheerVent® offers reliable ventilation without the risk of leaks. Fully thermally broken and using the same high-performance glazing as the rest of the S1 roof, SheerVent® is yet another feature that puts the S1 lantern ahead of the competition.
