Howells Patent Glazing has launched its new roof vent system, which is designed to integrate with the company’s patent glazing bars and is also compatible with other systems.
For complete flexibility, 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 & operating pole. EDPM glazing seals offer excellent long term performance.
