Sublime S2 SheerVent from Prefix

Prefix Systems have just launched the revolutionary new SheerVent for their S2 glazed roofing system, bringing all the innovation from the award-winning Sheerline S1 lantern into their next generation system for conservatories and glazed extensions.

With more experience than most in first generation roof vents, this new innovation from Sheerline is a game changer for the glazed roof market, bringing an integrated solution that doesn’t suffer from water ingress thanks to an integrated muntin bar with installation directly into the ridge baffle. 

S2 is re-defining the way in which glazed extensions look and perform, and now the dedicated SheerVent solution provides care-free long-term performance benefits and has been designed to seamlessly integrate with the S2 roofing system.

SheerVent’s sightlines are slimline and therefore it sits lower down than the traditional, clumsy looking first generation roof vents and is available in sizes up to 1.1 wide x 1.2m high. This new solution is fully thermally broken with 24mm glazing as standard and brings to market accessible 21st century automation through light, wind, and rain sensors for comfort and lifestyle benefits.

Chris Cooke, director of Prefix Systems commented: ‘The glazed and conservatory roof sectors have been plagued with poorly performing roof vents for decades. With the S2 SheerVent, we’re now able to offer our customers a next generation product that performs as well as it looks. The whole S2 glazed roofing system is already generating rave reviews from installation companies across the UK and this addition to the range will further support this view as we look to offer best in class solutions across glazed roofs, our award-winning WARMroof and through our outdoor living solutions, including Verandah.’
