Overall Scope:
Multiple glazing units had failed resulting in water pooling at the base of the transoms where the DGUS are situated. Prolonged exposure of the DGU perimeter seals in water would appear to be causing a breakdown of the seals and as such allowing moisture into the cavity. Remove and replace the defective External Cover Caps, Pressure Plates and External Gaskets. Deglaze and replace the Failed Glazing Units.
