Optimum Vent

Description

Attic ventilator OP-A412 is conceived for sloped roofs. Its sophisticated 4 wings design and openings allow optimal attic ventilation. Its ventilator structure punched openings eliminates all maintenance needs and prevents rodents and birds from getting inside. Its anti-gust deflectors prevents bad weather infiltration from any directions. OP-A412 Ventilator allows an advantageous cooler attic in summer and dryer in winter, extending structural integrity, adding superior interior comfort, creating also energy savings. This static ventilator offers a superior air aspiration and, with the help of wind, produces a chimney effect. Air is continuously exchanged. It exchanges attic air at a rate of 418 ft³/min, ventilating a 1000 to 1200 ft² area.

Avantages

  • Easy to install, screws are included

  • Flashing base works for sloped roof with a rise/run 2/12 to 18/12

  • Storm proof deflector

  • Quiet and maintenance free

  • Standard colours available: brown, grey, black and charcoal. Other colours available on special order (additional fee).

Application

Determine ventilator’s emplacement from inside, with a nail at the center of two trusses and at 8 inches from roof crest. Trace, with a chalk , the inside of the flashing having the nail in the middle, insuring to have flashing parallel to roof crest. Cut the opening, remove nails from top and sides of the hole that would bother flashing installation. Apply Condor Plastic Cement beneath flashing base. Slide flashing under side and top shingles and screw to roof plywood. Lift side and top shingles and fix them to the flashing with Condor Plastic cement. Pay attention not to put plastic cement on flashing gutter, bottom part. Fix metallic part of flashing so it will level. Place ventilator on its flashing. Fix ventilator’s head on its flashing, making sure that it is level with crest. Place a screw on each side in its pre-perforated hole. Apply Condor Plastic Cement to obtain a waterproof base.

Yield

The national building code requires adequate ventilation of the attic, according to the minimum standard of Section 9.19.1 or according to CSA CAN3-A93-M82.

Use

Ventilation is required by Canada’s building code. The issue remains in the fact of keeping a fresh attic. Ideally, attic temperature would be, a few degree close, similar to exterior temperature. In summer, using an Optimum ventilator allows heat elimination from the attic. This heat radiates inside and warms up the house. It can also create seepage problems, warp coatings or curl asphalt shingles. Thereby, an air conditioner must work continuously to cool down living areas. In wintertime, interior house air is warmer and contains more vapor pressure, in opposition to the dry and cold attic air. Vapor will have a tendency to migrate to the attic and condensate on cold building structure pieces. This condensation can humidify and compress isolation reducing at the same time the isolation factor and allowing more vapor migration. This humidity leads to ice formation on the roof, mildew and rot of the structure.

Roof Exhaust Trap Vent  

Description

Optimum roof exhaust trap is designed for sloped roof. It is designed to prevent freezing of the interior trap and its side openings allows an optimal air evacuation in all seasons. The interior is insulated to prevent any risk of condensation. This roof exhaust trap allows polluted air evacuation outside from a clothes drier, bathroom fan or range hood. Its structure punched openings eliminates all maintenance needs and prevents rodents and birds from getting inside. Its frontal deflector prevents infiltration that could block the interior trap.

Avantages

  • Easy-to-install

  • For all types of sloped roof 2/12 to 15/12

  • Frontal Deflector

  • Silent trap and maintenance

  • Standard colours available: brown, grey and black. Other colours available on special order (additional fee).

Application

Determine exhaust trap emplacement from inside, with a nail at the center of two trusses and at a minimum of 5 feet from a roof edge. Trace, with a chalk, a 5 inches square having the nail in the middle, insuring to have exhaust trap parallel to roof edge. Cut the opening, remove nails from top and sides of the hole that would bother exhaust trap installation. It would be preferable to install a flexible pipe at this point, avoiding to have to do it in the attic in a narrow area. Fix the flexible pipe around exhaust pipe neck et finish by putting a good quality duct tape. Insulate this flexible pipe, protect the insulation with a polythene (vapor barrier) et fix it good to the exhaust pipe neck with a good quality duct tape. Apply Condor Plastic Cement beneath exhaust trap flange. Slide trap under side and top shingles and screw to roof plywood. Lift side and top shingles and fix them to the flashing with Condor Plastic cement. Pay attention not to put plastic cement on exhaust trap gutter, bottom part. Apply Condor plastic Cement to obtain a good waterproof base.

Use

Optimum Roof exhaust trap prevents ice formation on interior trap, eliminating cold air from getting inside the house. Furthermore, its lateral air exhaust sends air from above instead of sending it directly on the roof, so preventing ice formation. Evacuation exhaust being more than 5 ½ inches above the roof prevents its blockage even if there is snow accumulation. Polluted air evacuation is better on the roof than the actual building practice which puts the air exhaust in soffits. With an exit put in soffits, most of the polluted air is going to come back in the attic, forming condensation and can damage to the roof structure or insulation. Even if there is a use of an attic ventilator, this excess of hot air and/or humidity can bring a reduction of effectiveness of this last and cause problems. Don’t forget that soffits are the entrance of cool air in the attic which dispels the polluted air by the Optimum ventilator

Wall Trap Vent 

Description

The Optimum wall exhaust is constructed to prevent ice formation on the inner cover and the infiltration of weather. So there is no possibility of cold air into the interior of the house. Is lined with felt, the inner door is silent at all times. The structure made of galvanized steel, prevents perforation from rodents as seen sometimes on plastic valves. The mesh shaped in the same material as the structure makes the intrusion of birds or rodents can not inward while remaining easy to maintain. With a collar of 9’’, the valve does not need an extension that would increase the number of joints and prevents any obstruction of the device. The opening angle down, in turn, allows an optimum air exhaust in any season while preventing lint and dirt from sticking to the wall.

Avantages

  • Easy installation

  • Solid construction

  • Quiet, efficient and maintenance free

  • Removable grill

  • Rodent proof

  • Wall remains clean powder coated finish

  • Available in white

  • Many sizes

  • Standard colours available: brown, grey and white. Other colours available on special order (additional fee).

Application

Determine the location of the valve from outside by drawing with chalk a circle of 4’’ in diameter. Cut the line of the wall and place the valve while connecting to inner pipe. Then tighten the 4 screws at the locations provided for that purpose to hold the valve on the wall. Apply a bead of sealant Condor to make the contour of the valve leaks.

Use

Optimum wall trap allow exhaust air to outside devices such dryers, bathroom fans and range hoods. For dryer exhaust only, please remove the removable mesh at the bottom of the valve to prevent accumulation of possible residue.

Intake Vents 

Description

The fan shaped triangular cathedral, the OP-RAC or rectangular triangle OP-RAR offers air intake necessary when there is no soffit eaves, allowing good ventilation of the attic when combined with a standard fan.

Avantages

These units are made of galvanized steel painted in the desired color. They can also serve expelled passive air.
These additional air intakes are configured to prevent any infiltration of water or snow allowing ventilation. Because of the unit directly from the surface of the roof, you should always ensure that the fan is cleared.

  • Standard colours available: brown, grey, black and charcoal. Other colours available on special order (additional fee).

Application

These units are useful when the air inlet to the soffit is :

  • Completely blocked by insulation

  • The outer wall touches the roof of the bridge

  • At the junction of a mansard and attic

Slant Back Metal Roof Vent 

Description

These low profile design metallic vents are alternatives to regular vents.

Avantages

  • This powerful model OP-TA100 with enclosed covers offer excellent protection against insect and rodent invasion. This design prevents air flow obstruction caused by leaves or pine needles which could accumulate on the roof and affect the air exchange in your attic.

  • All of our models are made of galvanised steel and covered with powder coating paint.

  • The media filter prevents all types of leaks associated with bad weather.

  • Quiet and maintenance free

  • Standard colours available: brown, grey, black and charcoal. Other colours available on special order (additional fee).

Application

Determine ventilator’s placement from the inside of the attic. Mark the appropriate diameter of the selected vent with chalk. With a saw, cut an opening in the roof along the diameter of the circle mark making sure to have the flashing parallel to the ridge of the roof. Slide flashing under side and top shingles and screw to the roof plywood. Lift side and top shingles and fix them to the flashing with Condor Plastic Cement. Pay attention not to put plastic cement on bottom part ot the flashing gutter. Centre the vent on the hole. Make sure that the top of the vent is level with the roof line. For all the static roof vents, the shingles must be on the top of the flashing to the inside of the opening. The front part of the flashing must be on top of the shingles. This part will served as a gutter. Place a screw on each side in its pre-perforated hole. Apply Condor Plastic Cement on the top seal to obtain a waterproof base.

Use

Attic ventilation is required by Canada’s building code. This requires keeping air circulating through the attic. Ideally, the attic temperature should be, within a few degrees of the temperature of the outside air. In summer, an Optimum ventilator allows excess heat to excape from the attic. Otherwise, excess heat radiates inside the house and warms up the interior. It can also create seepage problems, warp roof coatings or curl asphalt shingles. An air conditioner then must work continuously to cool down interior living areas. In wintertime, interior house air is warmer and contains more vapor, as opposed to the drier and colder attic air. Water vapor has a tendency to flow into the attic and condensate on colder building structure pieces. This condensation can dampen and compress insulation. This reduces the factor which then allow more water vapor migration into the attic. This humidity leads to ice formation on the roof, mildew and rot of the structure.
