Byute Flash 300mm x 10m

Byute Flash is a self-adhesive flashing tape with a heavy-duty aluminium foil facing over a thick layer of high-tack butyl rubber. This 300mm x 10m roll is the wide stock size, made for box gutters, valleys, skylights and large penetrations where a narrow tape would need several parallel strips. Peel the liner, press it down and it forms a long-lasting seal against water ingress, air leaks and UV damage across a wide range of substrates.

How To Apply It

Clean and dry the surface, peel the liner and press the wide tape down over the joint, smoothing it firmly across the full width. The conformable body dresses over irregular surfaces and tight corners, and the aluminium surface sheds water and reflects heat. Where the run needs two pieces, lap them and press the overlap down. It is a one-person job with no heat gun or roller required.

Applications

• Box gutters and valley flashings
• Sealing around skylights, windows and doors
• Roof penetrations such as vents and chimneys
• Flashing around solar panels, caravan seams and cladding

What You Need To Complete The Job

Frequently Asked Questions

When would I use the 300mm width?

Use it where a flashing needs wide coverage, such as a box gutter, a valley or a skylight surround. One strip of 300mm tape covers the joint without laying several narrow strips side by side.

Is the 300mm tape harder to apply?

No. It is a peel-and-press tape, so the wide body just needs firm hand pressure across the full width. It is more conformable than it looks, which is what lets it dress over corners and penetrations.

Can it be painted to match the roof?

Yes. The silver aluminium facing can be painted over so the flashing blends with the surrounding material, which keeps a wide flashing line from standing out.

Is it suitable for a box gutter?

Yes. It is a common repair and sealing tape for box gutters because the wide width covers the gutter seams and laps in a single strip, and the butyl backing seals against the metal.
