Natural Light Solar Attic Fan Benefits
Lowers attic temperature which reduces the load on the HVAC System
The most obvious reason for attic ventilation is to lower attic space temperature during the warmer months. Attic temperatures can exceed 160°F during hot summer days. Proper attic ventilation can reduce those temperatures by up to 50°F. No matter how much insulation is in the attic, heat can still transfer into adjacent living spaces. In fact, extra insulation can actually add to temperature increases because heat is trapped in the insulation. Proper ventilation evacuates this excess heat build-up. As the heat is exhausted, the work load of the air conditioning system is reduced, thereby saving energy and extending the life of the air conditioning system.
Extends the life of the roofing materials
Though asphalt shingles are designed to take the abuse of the sun for many years, they are subjected to greater temperatures when the roof decking is allowed to overheat, which is just what happens in an under ventilated attic.
In the cooler months, moisture is the most serious concern. Even with the use of vapor barriers to keep moisture from entering the attic, there are air leaks around ceiling light fixtures, bathroom exhaust fans that allow unwanted moisture into the attic. Moisture condensing on the framing members and the inside of the roof deck can lead to the growth of mold, mildew and rot in the roof deck and framing. A good indicator of moisture problem is rusty roof nails sticking through the roof deck.
Asphalt shingle manufacturers warranties require proper attic ventilation
Attic ventilation is required in cold environments - it evacuates the warm moist air that heat sources produce. Hot moist air lingering in the attic spaces can condense on the underside of the roof sheathing and rot it out and also causes mold to develop on the interior walls. Cold air in the attic space will not affect the temperature in the adjacent living spaces if properly insulated.
Good ventilation helps prevent ice dams, which begin to form when warm air in the attic melts the snow from beneath and creates runoff that refreezes on the colder eaves.
The Advantages of a Natural Light Solar Attic Fan
- Minimize backpressure of exhaust gases.
- Natural Light incorporates an angled throat within the flashing that provides a venturi effect, which increases airflow.
- Natural Light was designed from the ground up to minimize obstructions in the flashing and shroud.
- Maximize the exposure of the sun to the solar panel.
- Natural Light designed a mounting bracket that houses the solar panel that allows for angling the panel.
- Natural Light offers an optional special order remote solar panel which is installed away from the attic fan housing. It is used in applications where there is limited sunshine where the unit is to be installed. The remote panel is installed in a sunny area, capturing maximum amount of sunlight and therefore achieving optimal attic fan performance.
- Minimize the ambient temperature of the solar panel because power output rapidly declines as temperature increases.
- Natural Light powder coats the entire assembly, inside and out, in a neutral gray color thus ensuring that it does not act like a heat sink.
- The solar panel mounting bracket allows for an envelope of cool air to continually circulate around the entire solar panel.
- Adaptable to any location, roof type, in any environment.
- Natural Light is constructed of .080 (14 gauge) aluminum, the flashing and shroud are seamless ensuring weather tight installations.
- Stainless steel animal protection screen.
- Stainless steel hardware throughout.
- Powder coated to withstand any environment.
- Fifty year Neutral Cure silicone bonds the flashing to the roof.
