Key Properties
The importance of Roof Ventilation cannot be underestimated
to effectively eliminate the risk of condensation. Corovent
Slate, Tile and Ridge Ventilation Systems have been
specially developed to combat condensation through an
extensive range of stock and bespoke products. Corovent
matches all known Slate, Tile and Ridge designs with
special bespoke orders accepted on
obsolete or heritage products. Weathering, colouring
and textiles can also be easily and accurately matched.
A UV resistant hard wearing acrylic finish that is highly
weather resistant ensures colour stability for the life
of the product.
Slate and Tile Features
- Long reach felt sleeve supplied as standard. No
extra sleeve or site assembly required.
- Plain tile vents are installed simply replacing
only 3 tiles.
- Roofline slate vents are easily fitted avoiding
the need for cutting up slopes slates.
- Patented cassette system prevents water ever entering
the vent, instead it flows down
the internal channels to reemerge on the tile surface.

RV10K ROOFLINE TILE VENTS |
RV10K |
 |
The
unique COROVENT Roofline range offers
high or low roof ventilation through vents
that are almost invisible from the ground.
The design of the patented COROVENT ‘discreet
cassette’ system separates water
from the air, so the water is retained
above the roofline at all times. The Roofline
vents incorporate a factory fitted round
felt sleeve which penetrates the felt,
so no extra sleeve is required. This round
sleeve significantly reduces the felt
tearing that can occur around rectangular
spigots. |

It is always necessary
to cut and fold back the felt before fitting a
vent.
If this is done by following the COROVENT fixing
instructions no
leakage will occur. However a ‘felt weir’
isavailable as an extra safeguard, it guides any
condensation or rain water coming down the felt
away from the vent opening. |

All vents have been subjected
to 3 separate wind & rain penetration tests
and a deluge test to simulate extremely harsh
weather, based on conditions developed as part
of a DoE Partners in Technology Programme as
used by the Building Research Establishment
(BRE). All COROVENTS exceed the pass criteria
under all conditions. |
