Eaves Panel Vent

The Manthorpe Eaves Panel Vents are designed to maintain a flow of air to the roof space from outside, thereby allowing the escape of built-up moisture.

The Cross Flow Eaves Panel range of vacuum formed trays can be used to create an air passage between the roof felt and loft insulation to enable ventilation of the roof space.

The rigid, flat-pack panels fit easily with open or cottage style eaves and when used in this application, a 4mm fly screen is available.

Sizes are available to fit the majority of rafter centres in new build and refurbishment scenarios.

Products are available to provide 10mm2 airflow and, for large spanning roofs and loft conversions, Manthorpe can supply a 25mm2 airflow version.

The Manthorpe Refurbishment Eaves Ventilator can be fitted from within the roof space to allow for the easy refurbishment of existing roofs. Their flexibility allows them to fold to accommodate various roof pitches. The optimum level of ventilation can be achieved by tucking the insulation well into the fold of the ventilator.

The fitter should check which product meets the level of insulation required.
