Klober Rainwater Outlet Vent PVC KF650000 70mm High impact PVC Rainwater Outlet with a 70mm vent diameter and a length below the base of 255mm. Klober single-piece Rainwater Outlets are designed to provide a means of drainage for ventilated cold flat roofs which use insulation rather than unventilated cold flat roofs which rely on a roof void. Installation is similar to a flat roof terminal whereby the downpipe penetrates the roof into the roof void to which it is then connected to a drainage system to drain away any surface water that may build up on a flat roof system. This prevents ponding which can occur when rainwater outlets are not used. Excess surface water can cause flat roof systems to fail over time and lead to damage which in turn can cause leaking to occur. This particular rainwater outlet features a 70mm diameter downpipe ideal for connecting up to 70mm diameter drainage systems. Key features: Flat roof drainage for use in ventilated cold flat roofs. Allows rainwater to drain away preventing ponding. Simple to install.
