Coastal Group launches new Roto Inowa sliding system

Manufacturers of timber windows and doors can now obtain the Roto Inowa sliding system from Coastal Group. The partnership between the companies also makes specific tooling available.

Roto markets the Inowa system as a premium product, emphasising its weathersealing properties, wide size ranges and ease of use. A patented locking arrangement – unique to the system – compresses the circumferential gasket on all four sides of the sliding sash when closed.

The maximum weight of a sliding sash is 400kg and the maximum sash sizes range from 3,000mm tall to 3,600mm wide, with a width-height ratio of 3:1 being possible within Roto’s standard specification.

Coastal is supplying the SoftClose option as standard, which ensures a gentle, controlled closing action. A further SoftOpen function, to assist users when sliding the unit open, is available as an additional extra.

Roto recommends the Inowa system for a wide range of applications, including installations exposed to extreme weather, such as driving rain and high winds.

“Roto has had enormous success with the Inowa sliding hardware on architectural projects worldwide,” says Coastal Group Managing Director, Loren Jenner. “The system doesn’t compromise in any area, with high levels of security and weathersealing, plus ease of use and accessibility. It’s the perfect choice for any window manufacturer wanting to offer its clients a premium system, which feels great to operate and provides a home or other building project with all of these benefits.”

Vesa Nenye, head of Roto’s sales operation in the UK, commented: “We’re really pleased that Coastal has incorporated the Inowa system into its expansive portfolio. The Coastal profile designs have achieved brilliant results in weather performance testing. With an established brand and reputation for customer service, Coastal is ideally placed to supply Roto Inowa hardware to the timber window and door sector in the UK.

“Roto Group has had a very positive partnership with Coastal for a number of years – as a supplier of our Deventer gasket products – which are the perfect accompaniment to the Inowa system.”
