Cathedral Ventilation Lining

application area: commercial ventilation

use type: offices, choir rooms

project scope: reline with minimal access to duct

added value: 25-year guarantee on air-tight and one-piece liner

Background

The 12 existing chimney flues had to be lined to be made suitable for ventilation to serve the newly refurbished building.

From each room the flues were lined with VentilFlex-25 Green up to the attic level and out the top of the chimney. The team had to carry out a precision job in a confined space with minimal access to the duct.

Statement of work

VentilFlex-25 Green was chosen for this project because of its versatility and its long life span. The liner is light and comes as a soft and folded tube, which makes it easy to transport and to lower into the ventilation duct. Once in position, the liner is inflated and heated up, gradually assuming and maximising the internal dimensions of the existing ventilation duct. The resulting one-piece liner is corrosion resistant, completely air-tight and it carries a comprehensive 25-year guarantee.
