Keep your roof properly ventilated with the Timloc Black Rafter Roll (800mm, 6m), a roll formed eaves vent and roll-out rafter tray that stops condensation building up and causing serious damage to your property. It is ideal for new build and refurbishment work. For pitched roof eaves ventilation, it is a great fit on standard roofs pitched at 15° or more with an attic or loft space as the roof void; rafter spacings between 400mm and 600mm centres are accommodated.
