Howells Patent Glazing is pleased to announce the
launch of its new roof vent system.
Designed to integrate with the company’s patent
glazing bars, the vent 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.
Manufactured to British Standards using extruded
aluminium alloy, the vent is supplied in mill finish and can be anodized 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 anodized. Ancillary components are provided from
preformed aluminium alloy.
EDPM glazing seals offer excellent long-term
performance. Howells’ recommends a minimum roof pitch of 10 degrees.
Lower pitches can be achieved but are reliant on perishable silicone seals.
