A Bit Of Vent Invention

Sheerline has launched SheerVent, a new roof vent for its S1 lantern. The company says it is a new approach to ventilation that doesn’t compromise on the aesthetic of the aluminium glazed roof.

SheerVent can not only be specified on new projects, it can be retrofitted to existing installations.


Invisible improvement

The roof window sits flush with S1’s rafter bars unlike alternative systems sit on top of the bars. Sheerline claims it creates an almost invisible roof vent when closed.

SheerVent does not require the use of muntin bars.

According to Sheeline, the vent offers reliability without the risk of leaks and water ingress. The product is fully thermally broken and uses the same 28mm glazing as the S1.


Power and colour

Customers have the option to upgrade to powered actuators to create an automated intelligent ventilation system. This can be further enhanced by sensors, which can be installed away from the lantern to monitor for rain, wind and light.

Another feature of SheerVent is colour choice. It is offered in a standard colour range with the option of custom or dual colours.



At present SheerVent being is manufactured in-house by Sheerline to establish the company’s quality processes are maintained before it is rolled out to fabricators nationally.

According to Sheerline there is a waiting list for customers who wish to supply the product.


Wider lanterns at FIT

Also launched at FIT Show 2023 was Sheerline’s new three-way option. This adds more styles to the S1 roof lantern. It includes the same style as the two and four-way designs but gives customers an option for wider roofs that don’t rely on jack rafters.

Roger Hartshorn, Sheerline CEO, says: “SheerVent was hugely popular when we unveiled it at FIT Show 2023. It is the next phase in the evolution of one of our most popular products – the S1 roof lantern. Customers often ask us about ventilation options that don’t compromise on the overall quality and look of the roof lantern.

“With SheerVent, we have achieved this thanks to our continual investment in both our equipment and products. We are committed to overcoming the issues traditionally associated with aluminium products to ensure Sheerline keeps its competitive edge.”
