Preformed eaves ventilator for introduction between rafters in existing roof spaces.


The refurbishment eaves ventilator fits between rafters and can be placed in position from within the attic space. The ventilator bottom portion rests under the insulation. The ventilator top hinged portion hinges to follow the roof line. Its simple shape allows air to travel to and from the roof void. Insulation is not permitted to close the gap between the truss rafters. (Note: In existing properties air entry is normally introduced through the existing soffit. Please see CSV circular soffit ventilators or CRSV circular recessed soffit ventilators which may be used with this refurbishment eaves ventilator.)
