VENTS

VENT 1 - CAVIBRICK

Use
The Cavibrick is a high performance ventilator which may be used instead of a conventional airbrick.

Introduction
Manufactured to brick dimensions, the new Cavibrick is a multi-purpose module for incorporation within masonry walls. It may be used with a range of compatible straight and telescopic sleeves, to ventilate specific areas, rooms or voids. It may also be used without attachments, when ventilation of the cavity is required. The Cavibrick promotes high air throughput via a front rectangular louvered grille. 
The louvres are proportioned to maximise performance and spaced to comply with the latest British Standards requirements. The staggered louvres also offer an insect resistant status, which is not enjoyed on some standard airbricks. The louvres are moulded to cross-flow separators whilst to the rear of the Cavibrick is an integral waterdam to arrest rainwater which might enter during severe weather conditions.

VENT 2 - TYPE EROV

Use
Permits entry of air via eaves.

Introduction
The eaves roll-out ventilator (EROV) provides an alternative method of introducing an airflow route at the eaves. It is suitable for use in new and refurbishment work and is compatible with our range of soffit and fascia ventilators.

VENT 3 - TYPE TAV

Use
Provides cranked air- duct route from cavibrick to area at different level.

Introduction
The Telescopic Adjustable Ventilator extends or contracts like a telescope. It extends to a maximum of five brick courses. It is designed to accommodate the high performance cavibrick, or may alternatively be used with a conventional air-brick. Airflow can be directed to a specific area of the structure, at a different level. Where a greater variation is required beyond five courses, an intermediate sleeve is available to extend the range. The Type TAV offers an unobstructed airflow route to promote best practice. An accompanying DPC cavitray is also available to order, to provide damp proofing integrity as defined within the Building Regulations.

VENT 4 - OFV

Use
Alternative entry route for airflow servicing the roof space.

Introduction
The Over Fascia Ventilator is secured to the top of the fascia board and provides a different means of permitting air to enter and vacate the roof space.

Over Fascia Ventilators are suitable for new and refurbishment work. They eliminate the need for visible soffit ventilation and can also be installed in nonsoffit locations.

VENT 5 - W WEEP VENTS

Use
Dual-function product acts as a cavity ventilator permitting the cavity to breathe. Also acts as a weep to evacuate water from lintels, DPC's and cavity trays.

Introduction
The Type W may be used to provide the balanced air conditions demanded within the cavity in timber-frame construction. 
The equivalent airflow of an open perp is required every 1.5 metres around the base of the cavity walls and around the top of the same walls. Where such wall cavities are closed or compartmented with the presence of horizontal fire stops or similar, ventilation apertures are required below and above such stops.

Type W cavivents are designed for such purposes. Type W cavivents are available in a range of colours to blend with the adjacent mortar or masonry.
