Roof Ventilators


Cavity Trays Limited of Yeovil manufacture a wide range of ventilators for use in roofs, walls and floors. Various styles are available for new build and existing build/refurbishment applications.

Soffit entry ventilators include the SSV strip soffit ventilator which is produced in two widths to service roof pitches below 15° and above 15°. Soffit ventilators are also supplied as rectangular grills, circular and as prevented board. Alternatively, an over fascia model is designed to promote air flow without perforating the soffit.

At eaves level, the air passage is maintained by using one of several styles of eaves ventilator. The Type T resembles a butterfly with two projecting wings. It clamps each individual truss and introduces a flow route to either side. It is classified as universal as it suits almost all roof pitches and all truss centres. It is compatible with the soffit ventilators produced by Cavity Trays Limited.

The range of roof ventilators includes slate and tile vents, flat roof ventilators and horizontal intersection ventilators. All are described in detail within the literature entry. In total there are over seventeen different ventilation methods, permitting selection of the most appropriate to suit the style of project.

The cavibrick specification offers a higher standard coupled with watercheck, baffle and cross-flow controls. Available in a range of colours, the cavibrick may be used where an airbrick or lower standard style might once have been considered. The benefit to the Architect and Builder is a high performance module which is both pleasing in appearance and practical. The louvre layout satisfies BS requirements yet has been staggered to provide a level of insect resistance which is better than found on most styles.
