Description
Why buy the case
3.75″ is the seam width — it runs down every panel joint on the wall, which means it is the width you burn through fastest on a ZIP System™ job.
12 rolls = 1,080 linear feet. Rough math on 4 ft panels with 8 ft vertical seams:
- Roughly 135 panel seams per case
- A typical single-story house needs 3 to 4 rolls for the field — one case covers about 3 houses
- Framing a subdivision phase: this is the unit you want on the truck
Running out of seam tape mid-wall stops the crew. At 90 ft a roll, a case is the difference between taping the job and making a supply run.
What is in the case
| Quantity | 12 rolls |
| Roll size | 3.75 in × 90 ft each |
| Total length | 1,080 linear feet |
| Condition | New, sealed factory case |
ZIP System tape vs. DuPont butyl flashing tape
These are not interchangeable. Different adhesive chemistry, different system, different warranty.
| ZIP System Tape | DuPont Flashing Tape | |
| Adhesive | Acrylic, heat and UV resistant | 100% butyl |
| Install temperature | Down to 0°F | Down to 25°F |
| Exposure period | 180 days | 120 days |
| Warranty | 30-year system warranty with ZIP System™ sheathing | 10-year with Tyvek® WRB |
| Roller required | Yes | No |
If the wall is ZIP System™ sheathing, use ZIP System™ tape. Taping a ZIP wall with another manufacturer’s product is how a 30-year warranty stops being a 30-year warranty.
Specifications
| Construction | Acrylic adhesive + bonding layer + polyolefin core + slip-resistant surface |
| Installation temperature | Ambient air and substrate above 0°F (-18°C) |
| Maximum exposure | 180 days before covering with roofing or wall covering |
| AAMA 711 classification | Type A, Level 3 (per ICC-ES ESR-2227) |
| Code compliance | AC148 and AAMA 711-13, per ESR-2227 |
Installation — the part that causes callbacks
The roller is not optional. This is a pressure-sensitive tape. It must be rolled in with a ZIP System™ roller to reach maximum bond. Pressing it down by hand leaves a seam that looks sealed and is not — and on a case of 12 rolls, that is a lot of wall to do twice.
You also need:
- A dry substrate, free of frost and debris
- Ambient air and substrate above 0°F
- The wall covered within 180 days
Do not use it as a substitute for self-adhering ice and water barrier in roofing applications.
Buying more than one case?
Call (832) 463-7946 or email sales@85builders.com with your quantity and the job-site ZIP code and we will send pricing the same business day.
We accept Texas resale certificates for tax-exempt purchases.
Buying fewer than twelve?
If a full case is more than the job needs, we also sell this tape by the roll, including discounted stock with damaged packaging and factory-sealed product inside:
- ZIP System Flashing Tape 3.75″ × 90 ft — single roll
- Same roll on clearance — $30.99, carton shows dirt and wear from storage
The wider widths, also by the case
If you are buying 3.75-inch by the case, price the wider ZIP flashing tapes at the same time — they cover the details this width has to be pieced together for:
- 6″ × 75′ — the standard width for panel seams, windows and doors
- 9″ × 50′ — outside corners
- 12″ × 50′ — roof valleys, single piece
Watch the lengths: the wider rolls are shorter. The 6-inch comes 75 ft, the 9 and 12 come 50 ft. Call us and we will quote any of them by the case.
Frequently asked questions
How many houses does a case cover?
About three single-story houses for field seams, at 3 to 4 rolls each. Openings and details use additional tape.
Can I use this on a wall that is not ZIP System sheathing?
The adhesive is engineered for the ZIP System™ overlay. On a Tyvek® or standard WRB wall, use a butyl flashing tape instead.
Do I really need the roller?
Yes. Huber specifies the tape must be rolled in to achieve maximum bond. It is the most common installation mistake with this product.
How cold can I install it?
Down to 0°F (-18°C), with the substrate dry and frost-free.
Is this a genuine sealed factory case?
Yes. New, sealed Huber factory case. Not repacked from loose rolls.
How fast does it ship?
We ship next business day from Cypress, TX.
