New roof vent systems

Howells Patent Glazing has launched its new roof vent system, which will be exhibited at the FIT Show.

Designed to integrate with the company’s patent glazing bars, the vent is also compatible with other systems.

It can be accommodated into any application with overhead glazing, both single and double glazed. The vent attains the best achievable results when independently tested (Wintech) for air permeability, water tightness and wind resistance.

With a five-year warranty, the new vent system comprises electrically operated opening ventilators connected to an open/close switch or digital control panel with rain sensor and thermostat. The vent can be managed using a manual worm gear and operating pole.

Manufactured to British Standards using extruded aluminium alloy, the vent is supplied in mill finish and can be anodised or powder coated in a wide range of colours. Satin Hipca White (RAL 9910 Satin), anthracite grey (RAL 7016 Matt) and dual colour – grey external/white internal – are available as standard.

To complement the vent system, the patent glazing bars can be mill finished and anodised. Ancillary components are provided from preformed aluminium alloy.

EDPM glazing seals offer excellent long-term performance. Howells’ recommends a minimum roof pitch of 10º. Lower pitches can be achieved but are reliant on perishable silicone seals.
