Key Properties
Under some conditions, ridge ventilation has significant
advantages over other types of ventilation. Extracting from
the highest
point in the roof can increase the efficiency of air-flow.
This is particularly important for ‘passive stack’
ventilation systems for ‘wet rooms’, kitchens
and bathrooms. COROVENT Ridge is available to match all
popular ridge tiles, and can be made to match obsolete tiles.
They replace a normal ridge tile, and are virtually indistinguishable
from standard ridge tiles. The large ventilation capacity
12,500mm2 is suitable as an outlet terminal for most passive
ventilation systems, (shorter ridge tiles eg 300mm long
have a lower ventilation area), conforming to BS5572:1994
“Code of Practice for Sanitary Pipe work” and
BS5925:1991 (1995)”Code of Practice for Ventilation
Principles and Designing for Natural Ventilation”.
Ridge Features
- Extracting from the highest point in the roof can increase
the efficiency of air flow.
- Roofmatch service makes Corovent Ridge tiles virtually
indistinguishable from standard ridge tiles.
- Suitable as outlet terminals for most passive stack
ventilation systems.
- Ease of installation without the need to cut existing
ridge board in most cases.
- Selected lines offer a fitted extension sleeve as standard*.
