Why IPS Off-Ridge Ventilation?

A properly ventilated attic is essential to a more efficient, longer lasting roof and home. Attics need to "breathe" using a proper balance of roof intake and exhaust ventilation.

Proper attic ventilation allows insulation to function more efficiently and keeps hot air and moisture out. This extends the life of the roof deck and shingles and lowers home energy costs. Proper airflow also protects the attic and roof from damaging condensation, mold, and ice dams.

MORE EFFECTIVE EXHAUST

IPS Ventilation actively pulls air from the attic. The innovative round designs utilize the Venturi effect, using exterior wind to create suction. The outer pressure forces out hot or moist attic air unlike any other static vent on the market.

UNOBSTRUCTED AIR FLOW

IPS Ventilation allows air to flow unobstructed from the attic. Static vents are judged by Net Free Area (NFA). NFA is the open ventilating area minus any obstructions. While most vent manufacturers display a certain NFA, they do not take into account the change of direction the air must make to escape the vent. IPS Ventilation maximizes NFA, allowing air to flow the path of least resistance up and out of the structure.


UNMATCHED DURABILITY

IPS Ventilation bases are constructed with a thicker gauge aluminum than any competitive product. They won't be damaged when shipped or buckle when nailed and are guaranteed to last for the life of the roof. Each static vent is warrantied for the lifetime of the roof system on which they are installed.


INCREASED WEATHER PROTECTION

IPS Ventilation caps act as umbrellas for increased weather protection, shielding the attic from rain and snow infiltration. The protective caps are complimented by inner louvers designed uniquely for exhaust. These louvers effectively deflect rain, snow, debris and even embers from entering the attic space.

VENTILATION BASICS

Attic ventilation is the key to a long-lasting roof system. A balanced (intake and exhaust), properly ventilated attic allows the roof deck, shingles, and insulation to work at peak efficiency and prevents premature deterioration.


REMOVING HEAT

Ventilation is crucial in removing heat from the attic. Trapped heat can cause roofing materials and insulation to become brittle, significantly decreasing effectiveness. Brittle roofing materials can become leak points, leading to even more internal damage.

Hot attics also put more stress on air conditioning units, as the heat from the attic seeps into living spaces and raises overall home temperatures and cooling costs. Proper attic ventilation can also keep air conditioning ducts from overheating.


REMOVING MOISTURE

Attic ventilation is not just important during hot summer days.

A lack of proper airflow during the winter allows mold and mildew to grow on attic surfaces due to trapped moisture from condensation. Excess moisture can also warp and rapidly ruin roof decking. Moldy and warped roof decking force the homeowner to do an entire re-roof if not properly taken care of.


AVOIDING ICE DAMS

Inadequate airflow can also contribute to the formation of ice dams. If there is snow on the roof, trapped air in the attic can cause some snow to melt and re-freeze on the roof's edge. Ice dams block water from falling off of the roof. As the water freezes and thaws, it makes its way under the shingles and opens up leak points. Leaks caused by ice dams cause expensive interior damage.
