Compression Flashing 2.4m
Compression flashing is a Colorbond or Zincalume profile fitted with a resilient foam seal, supplied here in a 2.4m stock length. It closes the gap between cladding panels, roofing sheets and structural walls, sealing against water, dust and air leaks. The foam strip conforms to uneven surfaces on contact, and because the flashing installs by sliding between profiles with hand pressure, there are no screws, rivets or sealants to fit.
Key Features

Specifications
- Product: compression flashing
- Length: 2.4m (stock)
- Material: Colorbond or Zincalume pre-painted steel
- Thickness range: typically 0.55mm to 0.80mm BMT
- Widths: standard 50mm, 75mm, 100mm; custom widths on request
- Profile: compression profile with a resilient foam seal
Installation
Slide the compression flashing between the cladding or roofing profile and the structural member, pressing it in with firm hand pressure. The foam seal compresses to fill the gap and holds the flashing in place, so no mechanical fixing is needed on most installs. For roofs pitched 5 degrees and over, use it along the sheet edge to close the join before the cladding is fixed over the top.
Applications
- Sealing joins where roofing or wall cladding meets steel columns or piers
- Protective barriers at penetration points like louvers and plant equipment
- Dust and water blocking at flashings, parapets, barge ends and sleeper walls
- Retrofit and new construction on pitched and skillion roofs
What You Need To Complete The Job
Pair the compression flashing with L flashings for the straight angles on the roof, and use a barge gutter for the gable finish. Browse the Custom Flashing range for more profiles.
Frequently Asked Questions
Why is it called compression flashing?
Because it uses a compression fit. The foam seal compresses as the flashing slides between two surfaces, filling the gap and holding the flashing in place without mechanical fixings.
Do I need screws or sealant?
No. The foam seal holds the flashing and fills the gap, so most installs need no fasteners or sealant. Use a fixing where the flashing is on an exposed edge that needs extra hold.
What widths are available?
Standard widths are 50mm, 75mm and 100mm, with wider sizes available on request. The 2.4m stock length is the factory standard, and cut-to-length pieces from 0.3m to 6m can be ordered.
What surfaces does it suit?
It suits roofs and walls where cladding meets steel, masonry or timber, including pitched roofs of 5 degrees and over. The foam conforms to uneven surfaces, which is what makes the seal effective on rough profiles.
