Description
What it is — and when 4″ is the right width
OX ArticFLASH is a butyl-based synthetic flashing tape (butyl is a synthetic rubber) built for self-adhered window, door, and seam flashing. It is peel-n-stick with high initial tack, needs no primer and no mechanical fasteners, and installs in the cold — down to 0°F — where most butyl and asphalt tapes stop bonding.
The 4″ width is the narrow-work roll: sheathing seams and butt joints, narrow window jambs, and detailing around pipes, fasteners, and penetrations where a wider tape is wasted material. For standard window jambs and heads, step up to the 6″.
How it compares to DuPont Flashing Tape
| OX ArticFLASH | DuPont Flashing Tape | |
|---|---|---|
| Adhesive | Butyl (synthetic rubber) | Butyl |
| Installs down to | 0°F | 25°F |
| UV exposure | 6 months | 120 days (~4 months) |
| Warranty | 15 years | 10 years |
| AAMA 711 | Meets or exceeds 711-20 | Class A, Level 3 (highest documented level) |
| Price (4″) | $25 | $34.99 |
Straight talk: if your spec names an AAMA 711 performance level, DuPont documents Class A, Level 3. If it doesn’t, ArticFLASH installs colder, tolerates more sun, carries a longer warranty, and costs less.

Frequently asked questions
Is ArticFLASH the same as OX Butyl Flashing Tape?
Yes. ArticFLASH is the earlier name for OX Engineered Products’ butyl flashing tape — same product, same specs.
Can I install it in cold weather?
Down to 0°F. That is the main reason to reach for it over a standard flashing tape in winter.
Do I need a primer?
No, not on common construction substrates.
How long can it stay exposed before I close the wall?
Up to 6 months of UV exposure.
How fast does it ship?
Within next business day from Cypress, TX.
