That summer is on, the temperatures are starting to rise, and the moisture starts to build up in your attic insulation and framing. Attic ventilation is extremely important and can actually prevent many problems you notice from happening. If you have moisture or condensation problems in your attic, preventing this moisture build-up with proper ventilation can save your property from structural damage and even wood rot. Moisture builds up due to any heat source: such as a fan, a fireplace, an appliance, or a radiator running for a long time. It can also be caused by poor insulation in your exterior walls, lack of adequate ventilation, and problems with the design of your attic (ie not enough square footage). If you have any of these problems with your attic, you should consider adding vents to improve ventilation and reduce the chances of damage.
How Do Ventilators Work?
Attic ventilators are designed to keep the air flowing in a downward evaporation pattern. The air will move from a warm area to a cool area. This will reduce the moisture and condensation level in your attic and let your air conditioning unit operate more efficiently. There are different types of ventilators, depending on what type of ventilation needs to operate in your attic.
Pleated ventilators are boxes with a large opening that either screw into the roof or into the ceiling joists. The sheet metal effect enables air to easily move through the ventilated area. If the area needed to be ventilated, install a ventilator that is designed to draw air from the outside, without allowing a full flow of cool air back down the pole itself, which could cause the ventilator to overheat. If this happens, you could have a problem with your framing; the unit could bend or lead out of the ventilator opening, posing a danger to your property. If this occurs, check with an experienced professional about how to correct the issue. Another type of ventilator does not have an opening but is considered a ‘vented attic fan’. This unit is installed near the attic ventilation opening but does not have a cover as it can be quite dangerous. It is recommended that you don’t stand on the attic pole in the middle of summer and battery or install a CO alarm.
Tips for Successfully Installing Attic Ventilators
Before you go to measure, buy, and install your attic ventilators, make sure you do your research on the proper unit. Even if you have already decided on the best type of ventilator for your home, don’t try to install it on your own. As you install and adjust them, the attic will become extremely hot and can cause serious damage. Your electric panel can fall down if you don’t have the right protective measures in place. These units are very specialized and are not meant to be installed in open areas or to be put in an area where moisture can be a problem. If you are thinking about installing fans that are placed on the interior ceiling, be aware that the fans create large amounts of moisture in the space. This can lead to mildew and mold adhering to the surfaces and can cause the paint on your interior walls to flake off. Your attic space can be a breeding ground for particles that can cause allergies and other health problems.
Your attic will send you a serious message if it is not ventilated properly. This will keep the air flowing downward, reducing air vents and providing a temperature that is sufficient for good air circulation. If your air conditioner isn’t operating as it should, turning up the temperature, or putting on the air conditioner, can ruin the airflow.
