Q: Why Ventilate your attic?

*For proper ventilation, the attic of the building must have
an "entrance" for the air located between the roof and
walls and an air "exit" located on top of the roof. Combined
effects of wind and level differences give the air a chance
to enter or exit the attic. A backdraft is naturally created.

Q: My house has a sloped roof, what are the products
that can meet my needs?

You can use either the 60300 or the 60100 Series. Both
are equipped with Venmar's exclusive multislope base
that fits roof slopes from 2'' per foot (2/12) to 16'' per foot
(16/12).
60300 Series: Efficient to ventilate from 700
to 1200 sq. ft, the 60300 Series has a net ventilation
area of 1 sq. ft.
60100 Series: Efficient to ventilate up to 700 sq. ft,
the 60100 Series has a net ventilation area of 0.60 sq. ft.
The Venmar Attic Ventilator with a multislope base
is the ideal product to replace traditional roof vents!

Q: How can I evaluate my ventilation needs if
I have a sloped roof?

Most local building codes recommend that a minimum of
1/300 of the horizontal surface of the rooftop be to ventilated.

Also, the National Building Code (1995) recommends that
no less than 25% of the required openings be located at
the top of the space (with no less than 25% of the required
openings located at the bottom of the space).

1. Calculate the length (A) and the width (B) of the
attic located over the heated space of the house
and multiply (AxB).

2. Find the corresponding dimension in the supplied
chart and determine the VENMAR ventilator(s) that
best suits your needs.

Q: If I have a building with a flat roof, what
product can I use?

Venmar Attic Ventilators for flat roofs are the ideal solution for a
flat roof or to replace goosenecks. Their base has a 45° angle which
must be installed on a wooden base covered with the roofing membrane.

60310 Series:
Efficient to ventilate from 360 to 600 sq. ft, the 60310 Series has a net ventilation area of 1 sq. ft.

60110 Series:
Efficient to ventilate up to 600 sq. ft, the 60110 Series has a net ventilation area of 0.60 sq. ft.

Q: I want to replace my existing round ventilator
without changing the existing seal cover

Use the 60350 Series; it is designed to replace traditional
round ventilators without changing the existing seal cover
(30 cm, 12 round). Efficient to ventilate 700 to 1200 sq. ft,
the 60350 Series has a net ventilation area of 0.80 sq. ft.

This phenomenon allows the air coming from the outside,
which is dryer, to enter the attic by the "soffit" and the
humid air from the attic to exit the building. The evacuation
of humid air helps prevent the deterioration of the roof
(type of roofing material, insulation and so on).

During summer, the attic temperature can go up to 50°C.
The shingles submitted to this excessive temperature,
become dryer and the deterioration of the material allow the
infiltration of water and snow.

During winter, when the cold air from the outside meets
the warm air inside, the snow melts. This can produce
a patch of ice that retains water. The water infiltrates under
the shingles and seeps into the house.
