V2™VENT

Continuous Vents

One strip, four applications: soffit, ridge, eave, and inspection venting.

V2 Vents’ continuous vents run the full length of a balcony, eave, soffit, or ridge in a single piece instead of separate openings. Multiple flange styles fit stucco, milcor, and wood-frame construction, plus retrofit projects, all with a perforated exterior face that suits most rooflines.

Quality Manufacturing

What’s Built Into Every V2 Vent

V2 Matrix Intumescent Technology

Reacts at critical temperatures to defend against heat and flames

Rigid Hat-Channel Profile

Delivers high net free ventilation area (NFVA), built for balcony, ridge, and soffit runs.

Code-Aware Design

Built to align with Wildland Urban Interface code in California’s Chapter 5 (Chapter 7A) -> CWUI and beyond -> IWUI etc.

Independently Tested

Evaluated to ASTM E2886 and ASTM2912 for resistance to ember entry and direct flame impingement in both, horizontal and vertical directions.

Seamless Installation

Soffit Applications: Flanges

Multiple flange styles cover enclosed-eave installs. Because the vent is field-cuttable with a standard cold-cut chop saw and joins end-to-end, one product spans long soffit runs without visible breaks.

Standard Flange

Designed for classic nail-on installation under siding or wood trim.

Flange Front

Reverses installation geometry. Ideal for clean retrofit upgrades.

Retro-fit

Sized to slip directly into existing continuous wood/stucco vent slots.

Single Leg

L-shaped mounting option for tight soffit-to-wall applications.

Stucco/Milcor

Features integrated expanded plaster key ground for stucco embedding.

Roof Ridge Installations

Ridge Vent Applications: Universal and Standing Seam Metal Roofs

Several profiles fit under a vented ridge cap across roof types — standing-seam metal, tile, composite shingle, or wood shingle — for both new construction and re-roof projects.

Generic Ridge Detail – Standard Flange

Cor-A-Vent™ Ridge Detail – Standard Flange

Standard Flange system paired with Cor-A-Vent profile substrates.

Standing Seam Ridge Vent Detail – J Flange

Specialized J-Flange profile fitted directly inside metal standing seams.

Roof Ridge Installations

Balcony Inspection Vents

These same vents double as the inspection access required under SB 326 and SB 721 for balconies and other exterior elevated elements — with high net free vent area, available in G90 galvanized, stainless steel, and copper finishes, plus a Flange Front option built for retrofit.

Code Compliant Ventilation

Your home’s ventilation system should help defend from wildfire.

New building codes require vents to be made with fire-resistant, anti-corrosion material. We can help. Proper attic ventilation will help with airflow, and V2 Vents will help your home protect itself from ember attack, combustion and flames!

Critical Step

Sealing the Install with EverKem

  • Use EverKem 814+ intumescent fire caulking on every V2 Vents installation. Round eave vents use EverKem 136 mortar-based caulking instead, where mounting hardware isn’t practical and flanges run minimal.
  • Installation: Run a bead of EverKem behind the nailing flange before setting the vent — this keeps the seam between vent and building material airtight, closing off any gap embers could use to get in.

Code Compliant Ventilation

Providing necessary attic ventilation, but self-closing when it matters most.

Our fire and ember-resistant continuous vents for soffits provide the needed ventilation into attic space down the entire length of the soffit, roof ridge, or balcony.

V2 Vents are ideal for new construction in various materials and retrofit kits are available for existing continuous vents on the home. Strip vents such as ours do not use airflow-blocking baffles, resulting in more venting per square inch. Our continuous vents for soffits, roof ridges and balconies feature a stainless steel ember screen and intumescent, V2 honeycomb matrix that closes in the event of high heat.

It’s time for your home to protect itself.

* Within 5 miles of the coast, copper, stainless steel, or a powder-coated finish holds up better than standard galvanized against salt air. *
