GSE IN ROOF Junction for Top Flashing - Black

The GSE Junction for Top Flashing is a 375mm black flashing junction component used to join sections of top flashing within the GSE in-roof photovoltaic integration system. This piece forms a continuous, weathertight seal along the upper edge of the in-roof PV array where multiple top flashing strips meet, and is supplied in black to maintain a uniform appearance across the entire GSE system.

Key Technical Details

Key Features

• Connects adjoining top flashing strips at junction points along the upper perimeter of the GSE in-roof array, maintaining continuous weather protection
• 375mm profile provides sufficient overlap to bridge the joint between adjacent flashing sections and prevent moisture ingress
• Black finish is consistent with all other GSE in-roof system components, ensuring a clean and uniform appearance across the completed installation
• Lightweight at 0.294 kg, adding minimal load to the upper flashing assembly
• Purpose-built for the GSE in-roof top flashing system, ensuring precise fitment and reliable long-term performance at the flashing junction

Installation Notes

• This junction piece is used where two top flashing strips meet along the top edge of the in-roof array and must be installed as part of the adjustable top flashing configuration
• Top flashing is required when the existing roof tiles do not provide adequate overlap above the GSE half-frames at the upper boundary of the array
• A complete GSE top flashing installation typically requires the following components alongside this junction: top flashing strip, top flashing angle bead, pop rivets for angle bead, top corner support, top flashing right corner, top flashing left corner, and hook plates for centre
• Must be used exclusively with GSE in-roof mounting and flashing components to ensure correct system compatibility and warranty compliance
• Refer to the GSE in-roof installation manual for correct positioning, overlap orientation, and fixing sequence within the top flashing assembly
