GSE IN ROOF Pre-Compressed Foam Sealant Strip (5m Roll)
The GSE Pre-Compressed Foam Sealant Strip is a 5-metre roll of grey pre-compressed foam designed to create a watertight perimeter seal around in-roof photovoltaic arrays installed using the GSE mounting system. Applied to the flashing components at the edges and top of the array where they interface with the surrounding roof tiles, this sealant strip expands after installation to fill gaps and prevent water ingress across the array boundary.
Key Technical Details
- Product: GSE Pre-Compressed Foam Sealant Strip
- Manufacturer Reference: ART106373
- Roll length: 5m
- Cross-section dimensions: 20 x 40 mm
- Colour: Grey
- Type: Pre-compressed expanding foam
- Mounting category: In-roof integration accessory
Key Features
- 5-metre continuous roll provides sufficient sealant for multiple flashing junctions within a GSE in-roof array perimeter
- Pre-compressed foam expands to fill irregular gaps between GSE flashing components and adjacent roof tiles, accommodating variations in tile profile and surface
- 20 x 40 mm cross-section is sized to match the flashing-to-tile interface dimensions within the GSE in-roof system
- Creates a weather-resistant barrier at the edges and top of the array, reducing the risk of wind-driven rain or debris entering beneath the flashing assembly
- Grey colour provides a discreet, unobtrusive finish at the flashing perimeter that blends with common roof tile and flashing tones
Installation Notes
- Apply the pre-compressed foam strip to the GSE flashing pieces at the perimeter of the in-roof array where the flashing meets the surrounding roof tiles
- The foam is supplied in a compressed state and will expand after application to fill the available gap, so allow sufficient time for full expansion before assessing the seal
- Use along the edges and top of the array to complete the watertight perimeter in conjunction with GSE flashing, corner pieces, and junction components
- Must be used as part of a complete GSE in-roof installation to maintain system weatherproofing performance and manufacturer warranty conditions
- Refer to the GSE in-roof installation guide for guidance on foam strip placement, orientation, and the recommended sequence relative to flashing assembly
