application area: commercialuse type: extraction of cooking gases from kitchenproject scope: line brick extraction shaft to prevent grease build-upadded value: 25-year guarantee on liner, minimal downtime, easily fitted due to flexible materialBackgroundThis Hospital in Portsmouth has a busy commercial kitchen supplying restaurants and residents. Increasing reports of fumes from the greased-up brick extraction ducts have been a concern.A survey of the riser and plantroom was carried out to determine the most suitable solution. VentilFle-25 RKV for kitchen extracts was the preferred option due to the reduced access to the 30-meter brick riser.Statement of workThe shaft had been in use without a kitchen extract liner for the extraction of kitchen gases. This was a concern due to grease build-up, which can result in unpleasant odours within the building.VentilFlex-25 kitchen extract lining system was the chosen alternative lining method, with its jointless design, excellent heat resistance and fire rating, and crucially, an installation method that only required access at the top and the bottom of the riser.
