Rollex System 3 16″x12' Center Vent Soffit - Brown

This aluminum center vent soffit delivers 6.48 sq. in. net free air per lineal foot — that’s 77.76 sq. in. per 12’ panel. For Montana contractors dealing with ice dam prevention and attic moisture management, those numbers matter. The 0.019 gauge aluminum construction handles temperature swings without the warping and sagging common with vinyl alternatives after a few freeze-thaw cycles.

Ventilation Performance and Material Specs

The continuous center vent design provides 6.48 sq. in. of net free air per lineal foot. That’s not marketing fluff — it’s measurable airflow that meets code requirements for attic ventilation. The product meets or exceeds general building code requirements for net free ventilation area (NFVA).

Specification	Value
Material	High-quality, rust-resistant aluminum with oven-fused finish
Gauge	0.019 inch
Width	16 inches
Length	12 feet
Depth	3/8 inch (0.375 in)
Net Free Air	6.48 sq. in. per lineal foot (77.76 sq. in. per 12’ panel)

The oven-fused powder-coat finish isn’t just about looks. It’s what keeps the aluminum from oxidizing when moisture sits on it all winter. The finish resists dirt, rust, and breakage — critical when you’re dealing with Montana’s UV intensity at elevation plus the constant moisture from snowmelt.

Aluminum won’t sag or warp over time like vinyl. Twenty-year-old vinyl soffits often look like a roller coaster from heat cycling. This aluminum construction maintains its shape and requires only occasional cleaning with water.

Coverage Calculations and Installation

Each piece covers 16 sq. ft., with 12 pieces per carton providing 192 sq. ft. of coverage (1.92 squares). That’s straightforward math for bidding — no weird fractional coverage to deal with.

Coverage Details	Value
Coverage per piece	16 sq. ft.
Pieces per carton	12 pieces
Total per carton	192 sq. ft. (1.92 squares)

Installation uses standard aluminum soffit fasteners and J-channel. The panels can be cut with tin snips or a circular saw with a non-ferrous metal blade. Nothing special required — if you’ve hung aluminum soffit before, you know the drill.

The product installs into standard 16-inch soffit runs and is compatible with Rollex J-Channel, F-Channel, and Drip Edge accessories. It works with various siding types including vinyl, wood, and fiber-cement.

The limited lifetime warranty protects against manufacturing defects and finish failure. The aluminum is 100% recyclable — not that you’ll be tearing this down anytime soon.

Who Should Buy This

This product makes sense for jobs where proper attic ventilation prevents bigger problems down the road. The 6.48 sq. in. per lineal foot spec delivers measurable airflow for ice dam prevention. The aluminum construction outlasts vinyl in Montana’s climate.

Skip it if you’re looking for the absolute cheapest option. Solid aluminum soffit costs less if ventilation isn’t critical. Vinyl works fine in protected areas that don’t see extreme temperature swings.

The product delivers durability that looks new for decades. For contractors who understand that what goes under the eaves affects what happens on the roof, these specs justify the investment.

Frequently Asked Questions

How much ventilation does this actually provide compared to solid soffit?

The center vent design provides 6.48 sq. in. of net free air per lineal foot, totaling 77.76 sq. in. per 12-foot panel. Solid soffit provides zero ventilation. This vented version provides essential airflow to prevent ice dams and roof degradation.

Will the brown color fade in Montana’s UV exposure?

The oven-fused powder-coat finish resists dirt, rust, and breakage. The product includes a limited lifetime warranty that protects against finish failure. Rollex states the product will look new for decades.

Can this be cut with standard tools?

Yes — the panels can be cut with tin snips or a circular saw with a non-ferrous metal blade. No special equipment needed beyond what you’d use for any aluminum soffit installation.

What’s the actual thickness of this aluminum?

The aluminum gauge is 0.019 inch with an overall depth of 3/8 inch (0.375 in). That’s standard for quality aluminum soffit — thick enough to resist denting during installation.
