Construction-The Energysaver Grille is produced as a one piece moulding in tough, weather resistant PVCu. It is supplied with a snap-on mounting plate pre-drilled to suit 100mm (4inch) and 150mm (6inch) size ventilation installations.

How it works-Extract and passive ventilation systems all require external cowls or grilles to prevent draughts and rain ingress from entering a dwelling. Conventional grilles, even those with fixed louvres, are adversely effected by upward and cross winds that significantly reduce their Effective Area. This has serious adverse implications, particularly in relation to the statutory fresh air requirement for gas vents.

The problem is that the standard test to determine effective Area is always measured to 'free air' and wind effect can reduce Effective Area by up to 50%. Wind speeds as low as 5m/sec will make it impossible for most domestic mechanical ventilators to achieve 15litres/sec extraction.
