Why Worry About Attic Ventilation?
At Holden Energy Solutions we talk a lot about the importance of insulation and radiant barriers in keeping your home comfortable but there’s another critical factor, especially for homeowners in the Houston area.
Our weather here on the Gulf Coast of Texas is humid most of the year. When you take an area that’s warm, like an attic, and seal it properly, you invite another problem—mold. That’s why ventilation is critical to what we do.
Poor attic ventilation traps heat and moisture in your attic and ensures your energy bill will remain high. It also contributes to health problems.
With proper attic ventilation installed by Holden Energy Solutions, outside air flows into the attic and releases the heat buildup in that space. It also keeps it cooler, albeit it only marginally during our hottest months. Still, free flowing air is better than stagnant heat and a moisture problem.
What Is Proper Ventilation and How Is It Achieved?
Proper ventilation balances the air intake at your eaves or soffits with the air exhaust at or near your roof ridge. You want the correct amount of ventilation. Too little and you have a moisture problem. Too much and you allow cold air to penetrate and create more potential for leaks and possible problems in a hurricane. At Holden Energy Solutions, we analyze the exact amount needed and ensure you have the perfect balance.
Ventilation systems take many forms including:
- Ridge/Soffit Systems
- Slant Backs
- Wind Turbines
- Solar-Powered Ventilation
These vents work in tandem. The ridge vents run along the peak of the roof. Their external baffle increases air flow without allowing rain, snow, or dust to permeate your attic through them. The intake vents in this system are usually soffit vents. They contain tiny slits for airflow and can be narrow strips that butt together or take the form of wider vents that are located between the joists. Most newer homes have soffit vents.
Slant backs, like their name suggests, are metal squares with slanted backs. They direct exhaust or attic air upward. Their fully enclosed hood keeps critters, leaves, and pine needles out.
A wind turbine looks like a metal mushroom atop a roof. It catches natural wind currents, which cause an internal fan to rotate and propel the hot air out of the attic. They do not run by electricity so they are best used in areas where the average winds are about 5 mph.
Solar-power vents in some ways work similarly to wind turbines in that the fan is powered by something other than electricity—in this case, solar power. The fan will propel hot air out of the attic and unlike the wind turbine, average wind speeds in the area are not important. There is enough solar electricity to run the fan even on cloudy days.
