Balanced Ventilation

How It Works

A balanced vent system is one that best utilizes three natural forces: air pressure, the thermal effect and diffusion. Basically, for every square inch of ridge (exhaust) vent you must balance it with at least one square inch or more of soffit (intake) vent.

COR-A-VENT®_{ridge & soffit vent products offer:} • V-600 products – 20 sq. in.

Net Free Vent Area (NFVA)/lineal foot • V-400E & X-5 products – 17 sq. in.

NFVA/lineal foot

• V-300 & Fold-A-Vent®_{products – 13.5 sq. in.}

NFVA/lineal foot

• S-400 Strip Vent line offers 10 sq. in. NFVA/lineal foot

With a ridge and soffit system, cooler ventilation air will be drawn into the attic (or roof cavity if a cathedral ceiling) through the soffit/eave vents located within the positive pressure (intake) areas. It will exhaust through the vents in the negative pressure areas, at the ridge. Wind moving

over the ridge literally “siphons” the hot/moist air out of attic. If the ridge vent were to be installed alone, then part of the ridge would become an inlet vent to relieve this “draw”. This could cause weather infiltration.

The ridge vent must always be installed in combination with some form of soffit/eave intake vents. Do not use ridge vents with gable vents or other roof mounted vents.

The “Ventilation Chute”, or air passageway between the soffit and the ridge must not be blocked or restricted so as to impede airflow. Once again, the ridge vent in this situation can act as intake andexhaust, causing weather infiltration.

For a more attractive ridgeline, COR-A-VENT recommends installing the ridge vent to the very ends of any given ridge. A ridge that is the same height from end to end

makes our vent even less noticeable.

Please refer to the backside of this page for examples of typical continuous soffit vents and vent chute details.

Figuring Your Ventilation Needs:

V-400E: Square footage of building footprint X .48 = Lineal Feet V-400Eneeded 17

V-300: Square footage of building footprint X .48 = Lineal Feet V-300 needed 13.5

Example: 25' x 50' = 1250 Sq.F. 1250 x .48 = 600

600 ÷ 17 = 35 L.F. V-400E needed

The above formulas will give the amount of COR-A-VENT ridge vent needed for a 1/150 vent ratio, provided an equal or greater amount of soffit venting is used. For a 1/300 ratio, (building code minimum) use half the amount of ridge vent. Note: Code interpretation may vary. Consult your local building dept.

For the best appearance, install COR-A-VENT continuously the entire length of the ridge.

Note:Should you need any assistance in designing your ventilation system, fax or mail a sketch and information to our technical services department. COR-A-VENT will respond with recommendations for your particular building design.

COR-A-VENT®_{has promoted and taught}_{balanced ventilation}_{from the day we}

started. It’s a concept all vent manufactures readily endorse. Unfortunately, that information doesn’t always end up in the hands of the person designing the building or installing the vents. Balanced venting helps insure the performance you expect from ridge venting – uniform, increased airflow through the roof cavity without weather infiltration.

Balanced venting:An equal or greater amount of vent opening(sq. in net free vent area/NFVA) in the soffit (intake) than at the ridge. For example, our V-400E products have 17 sq. in NFVA per lineal foot. To balance this, you need 2 soffit/eave/intake vents of approximately 8.5 sq. in. per lineal foot (1_/₂_{of 17 in}

each overhang).

Balanced venting:

Continuous soffit vents are recommended, especially for venting cathedral ceilings. Wherever there is ridge

vent above, there should be soffit/eave/intake vents on the structure below. Also, COR-A-VENT strongly recommendsusing of one of our V-300 products (available in 11, 81_/₂_{or 7" widths) on cathedral ceiling and hip roof applications.}

V-300 delivers 13.5 sq. in net free vent area. The volume of space to be vented in cathedrals is smaller. Therefore a lower profile (5/8") vent is called for to further reduce the chance for infiltration. When installing a ridge vent system, allother vent openings (except soffits) must be closed off.

USE BALANCED AMOUNTS OF SOFFIT VENT TO RIDGE VENT

Continuous aluminum strip vent – 8-9 sq. in. NFVA per lineal foot.

8" x 16" under eave cornice vents with maximum spacing of 4' apart – gives 14 sq. in. NFVA per lineal foot.

Continuous perforated panels – 1' wide overhang (typical) – gives 12-13 sq. in NFVA per lineal foot.

COR-A-VENT’s S–400 Continuous Strip Vent – 10 sq. in NFVA per lineal foot.

Maintaining an unrestricted air passageway between the soffit and ridge is crucial to the performance of the vent system, and must not be blocked or restricted. COR-A-VENT recommends a minimum 2" air space between the roof sheathing and vent chute or insulation

COR-A-VENT®_{, Inc.} _{is proud to introduce the first shingle-over}

ridge vent made from 100% pre-consumer recycled plastic, new

Revolution Rolled Ridge Vent.

Revolution (REV-11) is the only truly “Green” ridge vent available. The 11-inch wide by 20-foot long plastic vent core is made entirely from the same polypropylene plastic used to manufacture all of COR-A-VENT’s other products. We meticulously capture the excess scrap during production, reprocess it and feed it directly into the Revolution, keeping it out of landfills while also reducing the use of petroleum needed for

new plastic production.

Revolution’s precisely spaced ventilation channels provide 12 square inches of Net Free Vent Area per lineal foot to promote the removal of damaging moisture and heat from inside your attic. This helps reduce heating and cooling loads when used in conjunction with balanced intake ventilation. The simple, yet highly effective structural design of Revolution supports power-nailability for easy installation on asphalt shingle roofs, while also providing protection from rain, snow & insects.

4. Beginning at end of ridge, apply vent with minimum 1¾" nails (2 coils provided in box) following “NAIL HERE” guides along vent cap. Only apply nails within the area between leg cavities – DO NOT apply nails outside of “NAIL HERE” guide marks. Vent may be power nailed or hand nailed. Do not overdrive nails. Apply ﬁ rst four nails (two on each side), then remove colored band to unroll rest of vent. Continue to apply according to marked guides. Repeat Step 3 to seal opposite end of vent.

5. For runs longer than 20 feet, additional vent rolls can be applied. Line up end of additional vent roll with previous roll by overlapping at offset lip, then apply Peel-&-Stick end cap to seal junction. Follow Step 4

to apply rest of vent.

6. Center shingle cap on vent and nail along “NAIL HERE” guideline. Continue applying caps until all vent is covered with ridge caps. Do not overdrive nails. Nail head should be ﬂ ush with top of shingle, without indenting it. Pre-forming caps in cold weather helps avoid cracking.

Revolution Installation Instructions

1. Measure a 3" slot, 1½" each side of ridge centerline. This allows for a 2x ridge board or smaller. Snap chalk lines the entire length of the ridge. Cut slot with circular saw and clean out debris. Set saw depth so as not to cut roof rafters. Stop slot 12" short of any ridge end, intersecting ridge or obstruction (such as a chimney).

2. Cut clear band around roll, leaving colored band to hold all but the starter section together. Vent installs with legs down and ﬂ at cap on top.

3. Remove backing from 1 Peel-&-Stick end cap section. Apply half of the section to end of the vent, starting with the top cap. Wrap other half of end cap down and underneath vent legs and Snow Screen to close off end of vent.

WRAP END FROM TOP TO UNDERSIDE OF VENT

7. For shorter runs of vent, trim areas provided every 12". Cut with utility knife, snips or saw, taking care to follow recognized manufacturers’ safety procedures for each.

Be careful not to touch knife blade. Always cut in a direction away from yourself. Wear proper hand and eye protection. 12 Square inches Net Free Vent Area per lineal foot. 20' long x 11" wide x 5/8" thick.

For use on roof pitches 3/12 - 16/12.

Call our technical department for any special application questions.

Important notes: COR-A-VENT ridge vents should always be installed with soffi t/eave/intake vents of equal or greater area. All other vent openings (except soffi ts) should be closed off. The air passage way or “Ventilation Chute” between the inlet (soffi t/eave/intake) and the outlet (ridge) vent must not be blocked or restricted. COR-A-VENT products meet or exceed all nationally recognized building codes for ventilation.

COR-A-VENT

®

has the answer for stopping all forms of weather infiltration with the

X-5ridge vent:The Complete Solution– superior ventilation performanceandthe ability to

stop rain and snow infiltration cold…even in weather extremes.

X-5employsdual protectionto stop infiltration. First is theAWF– theactive weather foil, a specially designed,wind-activated, weather impenetrable valve– permanently attached to the bottom layer of ourX-5vent material.

The AWF will stop wind driven rain from penetrating your roof cavity. Second is theenhanced

snow screen, an air-permeable filter that keeps out snow, even at low wind speeds, while still allowing hot, moist air to flow out of the attic.

(13)

How does the AWF work? We’ve engineered the valve to close at 10 MPH(± 2 MPH). The leading (windward) edge of the AWF, which is shaped like an airfoil, catches the wind blowing at it, whether directly or at an angle, and snaps shut. Meanwhile, on the downwind (leeward) side, the vent remains open and continues to exhaust hot, moist air from the attic. Below 10 MPH, the valve opens completely for positive ventilation fromboth sidesof the vent. TheAWFeffectively blocks weather from entering through the vent’s flutes.Dade County acceptance1and our own in house rain tests confirm this. The harder the wind blows, the tighter the AWF seals.

How long will the AWF last?Developed from a special formulation of Reemay®_{non-woven with a UV inhibited proprietary coating, it’s} guaranteed to last. Tested to the same standards as composition shingles, the AWF fabric was subjected to a 5000-hour exposure test from a Xenon Arc weatherometer.

That’s the

equivalent of25 years exposureto south Florida or Death Valley sun. The results –

no significant embrittlement or degradation.

X-5

is made from a special 4mm sheet of extruded PP. This means less restriction and more airflow. At the same time, it has

17 sq. inches of NFVA(Net Free Vent Area) per lineal foot, which exceeds all national building code requirements.

X-5

will work with shingle, metal, tile and cedarroofs and is also a

perfect Roof-To-Wall vent.

X-5

in architectural design calls for flexibility and COR-A-VENT’s V-300 and Fold-A-Vent (FAV-20) families of ridge vents deliver the unique flexibility to adapt to just about any roof design – whether on new construction or when re-roofing. V-300 & FAV-20 are low profile (5_/₈_{" high) and recommended for hard to ventilate roofs,}

such as cathedral ceiling and hip roofs. Both are available in 11", 81_/₂_{" and 7" widths}

and work great with 3-tab or architectural shingles as well as cedar shake, slate, flat tile and metal roofs. Your ridge line will look sharp with V-300 or FAV-20.

Protection…

is what COR-A-VENT offers with our enhanced snow screen (V-300E & FAV-20E) to keep out wind-driven precipitation. The highly breathable filter will allow hot, moist air out, but won’t let weather in.

Adaptability…

is what V-300 & FAV-20 offer in any hip design for a clean, uncluttered appearance. They are ideal for steep pitch and short ridge length hip roofs and can be extended all the way down the hip to the gutter for a smooth, unbroken roofline. V-300 7" or FAV-20 7" are sized for use with RIDGLASS™ and Z®_{Ridge* high profile hip and}

ridge caps. Call our technical department for help with hip installations or unique applications.

Reliability…

is what you get with V-300 & FAV-20. Our 4-ply design delivers 13.5 sq. inches of Net Free Ventilation Area (NFVA) and the dimensionally-stable, profile extruded polypropylene material is impact resistant and self-cleaning, but still cuts easily with a utility knife. Installation is a breeze. V-300 & FAV-20 are power nailable and go on fast and straight – they won’t compress or hump like other low profile products.

Fold-A-Vent…

is the perfect 20' solution. It is formed into 5 – 4' sections. The folds “relax” as the sections are extended, so the vent goes on flat and smooth. While nailing the first section, our exclusive

“Yellow Starter Band”keeps the remaining 4 sections together. Install with your power nailer and standard 11_/₂_{" coil nails. The unique routed}

center slot allows you to center the vent on the ridge by sighting down it. No need to snap chalk lines. The flexible center hinge allows easy alignment on roofs up to 16/12 pitch.

Unlike “rolled products”, the FAV-20 bundle stays put on the ridge while you install it – you won’t end up chasing it down the roof or picking

it up off the ground. Corrugated rolled vents look nice in the package, but wait until you try to unroll them! They have a

built-in curl. That’s because the vent is rolled into a package while the plastic is still warm. Roll it out and

it wants to come right back. Installation is tougher and you’re left with a series of humps to flatten out.

COR-A-VENT®_{has promoted and taught}_{balanced ventilation}_{from the day we started. It’s a concept all vent manufacturers}

readily endorse. Unfortunately, that information doesn’t always end up in the hands of the person designing the building or installing the vents. Balanced venting helps ensure the performance

you expect from ridge venting – uniform, increased airflow through the roof cavity without weather infiltration.

Balanced Venting:An equal or greater amount of vent opening

(sq. in. net free vent area/NFVA) in the soffit (intake) than at the ridge. For example, our V-300 & FAV-20 products have 13.5 sq. in. NFVA per lineal foot. To balance this, you need 2 soffit/eave/intake vents of at least 6.75 sq. in. per lineal foot.

Balanced Venting: Continuous soffit vents are recommended,

especially for venting cathedral ceilings. Wherever there is ridge vent above, there should be soffit/eave/intake vents on the structure below.

Also, COR-A-VENT strongly recommendsusing one of our V-300 or FAV-20 products (available in 11", 81_/₂_{" or 7"}

widths) on cathedral ceiling and hip roof applications. V-300 & FAV-20 deliver 13.5 sq. in. net free vent area. Because the volume of space to be vented in cathedrals is smaller, a lower profile (5_/₈_{") vent is needed to further reduce}

the chance for infiltration. When installing a ridge vent system, all other vent openings (except soffits) must be closed off.

USE BALANCED AMOUNTS OF SOFFIT VENT

TO RIDGE VENT

Balanced ventilation –The right proportion of venting.

COR-A-VENT®_{products meet or exceed all nationally recognized building codes for ventilation. COR-A-VENT products are}

covered under the following patents: 5,054,254; 5,339,582; 5,439,417 5,542,882; 5,603,657; 5,704,834; 5,921,863; 6,039,646; 6,213,868; 6,558,251B2; 6,589,113; D465,839 — additional patents pending.

For the best appearance, install V-300 & FAV-20 products

continuously the entire length of the ridge.

Figuring Your Ventilation Needs:

V-300 & FAV-20 have 13.5 sq. in. NFVA/lineal foot.

V-300: Square footage of building footprint X .48 = Lineal Feet V-300 or FAV-20 13.5 or FAV-20 needed

Example: 24' x 70' = 1,680 Sq.F. 1,680 x .48 = 806

806 ÷ 13.5 = 60 L.F. V-300 or FAV-20 needed

The above formulas will give the amount of COR-A-VENT ridge vent needed for a 1/150 vent ratio, provided an equal or greater amount of soffit venting is used. For a 1/300 ratio, (building code minimum) use half the amount of ridge vent.

Note: Code interpretation may vary. Consult your local building dept.

Note: Should you need any assistance in designing your ventilation system, fax or mail a sketch and information to our technical services department. COR-A-VENT will respond with recommendations for your particular building design.

1.Measure a 3" slot, 11_/₂_{" each side of ridge}

centerline. This allows for a 2x ridge board or smaller. Snap chalk lines the entire length of the ridge. Cut slot with a circular saw and clean out debris. Set saw depth so as not to cut roof rafters. Stop the slot 12" short of any ridge end, intersecting ridge or obstruction (such as a chimney).

2.Cut the 3 clear bands leaving the colored band to hold all but the starter section together. Turn the vent bundle upside down to expose the underneath side of the starter section end. Follow steps 3 – 4 to create its own Folded End Cap.

6.Continue to tack nail both sides of entire length of vent. Use nail pattern shown in step 4. Center shingle cap on vent and nail. Continue nailing until all vent is covered with ridge caps. Be careful not to overdrive nail. Nail head should be flush with top of shingle, without indenting it. Pre-forming caps in cold weather helps avoid cracking.

5.Continue applying FAV 20 by walking out remaining sections. Pull firmly to fully extend, center vent on ridge and nail other end down. Make sure vent matches roof pitch before nailing both sides in place. If necessary add FAV 20 until entire ridge is covered. Use a utility knife to cut last section to length. Fold end to finish (steps 3 – 4). Caulk between bottom edge of vent and roof.

B A

3.Use a utility knife to cut out a “V”shaped notch from the centerline approximately 13_/₄_{" in}

from edge and remove loose material (A). Cut through the bottom 3 layers of the vent as pictured (B) (located approx. 13_/₄_{" from &}

parallel to the end). Remove loose pieces. Be careful not to cut into top layer.

4.Fold flap under and secure with a 2" roofing nail. This allows the nail to penetrate an extra layer of vent material (inset). Align starter end

1_/₂_{" in from edge of roof, and centered on ridge.}

Be sure to caulk between bottom edge of vent and roof. Nail the starter section at points A, B & C, 2" up from edge.

If Architectural Shingles, Shakes or roofing with an irregular surface is used, apply a bead of caulk to roof deck before installing vent. This will seal any gaps that could allow weather penetration under the vent.

COR-A-VENT products are low profile,from 5/8'' to 1'' high, and virtually disappear beneath the ridge cap. Made of thermally stable, crush resistant polypropylene (PP) sheets*, our vents don’t compress over time, so roofing screw holes don’t elongate and leak. COR-A-VENTis easy to install, with a minimum of waste. A wide, solid base on all

our products insures a good seal under the vent. The vent’s cross section lets maximum air flow through, while our enhanced vents (V-600TE & V-400E) keep

fine powdered snow out. COR-A-VENT’sdesign also works with any closure and cap system.

We’re the leading manufacturer of attractive, tested vent applications for metal roofing.

Standing Seam.

This is becoming the preferred roofing system for builders of low-rise commercial, industrial

and institutional buildings. More than 50% of these types of structures erected in the past several years have standing seam roofs and more than 1 billion square feet of standing seam metal roofing has been installed. This roof-style is designed to be weather-tight, with a clip-fastened system beneath the steel panels to cut down on roof penetrations. Paired up with COR-A-VENTridge vents, it’s a beautiful roof that will last.

Profile.

Also known as “screw down” roofing, this system is durable, lightweight and relatively inexpensive compared to other

types of metal roofing and is installed over and

fastened directly to the decking underneath. Profile panel is widely used with industrial and agricultural structures like garages and utility buildings, or horse and animal barns.

COR-A-VENTis a perfect match for this

investment – the one on the roof and everything underneath it.

Metal Shake.

With the look of shingle and the durability of metal, this alternative to typical residential roofing has plenty of options.

Choose from metal shakes that resemble cedar wood or tile, or stone-coated products that resemble asphalt

shingles, like the inset photo of stone-coated shingles from COR-A-VENTcustomer Gerard Roofing Technologies.

COR-A-VENTcomes in a variety of widths

to match the cap sizes of today’s popular metal shake roofs.

_{” Eave Vent Designed to Fit Between the Rafters}

Introducing COR-A-VENT’s Latest Soffit Vent Innovation—

Providing soffit ventilation for open-rafter construction has long been a headache for many builders. The options have been few, consisting mainly of a couple of screened-over holes in the blocking or a few metal grates every two or three rafter bays that don’t provide nearly enough ventilation and, quite honestly, don’t look very good.

But COR-A-VENT®_{has the answer} with its newest product, Raft-A-Vent™, a 22.5" long vent strip designed to fit between the rafters, on top of the blocking.Raft-A-Ventis the ideal product for this situation.

At only one inch thick, Raft-A-Vent

will virtually disappear under the eave, but still provides 18.75" of Net Free Vent Area per piece and is designed to run continuously in every rafter bay* to provide the superior intake ventilation you need for a balanced vent system.

Good ventilation helps reduce moisture buildup and the possibility of mold growth.

For an unmatched system, pair Raft-A-Vent

up with any one of COR-A-VENT’sridge vents, like V-300 81_/₂_"_or_FAV-20₈1_/₂_"_,

both UL®_{Class A f}_i_{re rated products}_. *See the back of this flyer or go to cor-a-vent.comfor

Example: 25' x 50' = 1250 Sq.F.

1250 x .48 = 600

600 ÷ 17 = 35 L.F. V-400E needed

The above formulas will give the amount of COR-A-VENT ridge vent needed for a 1/150 vent ratio, provided an equal or greater amount of soffit venting is used. For a 1/300 ratio, (building code minimum) use half the amount of ridge vent.

Note: Code interpretation may vary. Consult your local building dept.

For the best appearance and performance install COR-A-VENT ridge and soffit vents

continuously at the ridge and in the soffits.

COR-A-VENT products meet or exceed all nationally recognized building codes for ventilation. COR-A-VENT products are covered under the following patents: 5,054,254; 5,328,407; 5,339,582; 5,439,417; 5,542,882; 5,603,657; 5,704,834; 5,803,805; 5,839,059; 5,921,863; 6,039,646; 6,213,868; 6,558,251B2; 6,589,113; 6,598,356; D465,839 – additional patents pending.

Note:Should you need any assistance in designing your ventilation system, fax or mail a sketch and

information to our technical services department. COR-A-VENT will respond with recommendations for your particular building design.

COR-A-VENT®_{has promoted and taught}_{balanced ventilation}_{from the day we}

started. It’s a concept all vent manufactures readily endorse. Unfortunately, that information doesn’t always end up in the hands of the person designing the building or installing the vents. Balanced venting helps insure the performance you expect from ridge venting – uniform, increased airflow through the roof cavity without weather infiltration.

Balanced venting:An equal orgreater amount of vent opening(sq. in. net free vent area/NFVA) in the soffit (intake) than at the ridge. For example, our V-300 products have 13.5 sq. in NFVA per lineal foot. To balance this, you need 2 soffit/eave/intake vents of at least 6.75 sq. in. per lineal foot (1/2 of 13.5 in each overhang).

Balanced venting:

Continuous soffit vents are recommended, especially for venting cathedral ceilings. Wherever there is ridge

vent above, there should be soffit/eave/intake vents on the structure below. Also, COR-A-VENTstrongly recommendsusing of one of our V-300 products (available in 11, 81_/₂_{or 7" widths) on cathedral ceiling and hip roof applications.}

V-300 delivers 13.5 sq. in. net free vent area. The volume of space to be vented in cathedrals is smaller. Therefore a lower profile (5/8") vent is called for to further reduce the chance for infiltration.When installing a ridge vent system,allother vent openings (except soffits) must be closed off.

USE BALANCED AMOUNTS OF SOFFIT VENT TO RIDGE VENT

Maintaining an unrestricted air passageway between the soffit and ridge is crucial to the performance of the vent system, and must not be blocked or restricted. COR-A-VENT recommends a minimum 2" air space between the roof sheathing and vent chute or insulation
