Sliding windows and doors are particularly susceptible to water drainage problems in the exposed outer portion of the slider track. Water build-up can cause degradation of the finseal on the underside of the sash, leading to leakage, mildew and jamming due to icing.
The HI-FLO drainage system facilitates positive water removal from both inner and outer slider tracks.
Water draining off the window into the sill tracks flows through the sill and is released outside through the HI-FLO drainage weepers.
Wind pressure and insects are blocked from entering the house by the positive closing action of the HI-FLO drainage weeper door.
