Circulate Air In Attic

Gable vents may circulate air through only a small percentage of your attic.

Circulate air in attic.

Here are the signs to look for. Plywood to move around on. Whole house fans powered attic fans. Snow melts and the water refreezes on the cold eaves creating ice dams.

Static roof line vents are effective for ventilation but generally aren t recommended due to issues with leaks. This will use more energy and make your air conditioner work harder which will increase your summer utility bill. This is normally the point where air enters your attic. The only way to lower the attic temperature is to pass air over the lumber and insulation lots and lots of air.

Warm air that escapes living space also carries moisture that will condense on rafters or roof sheathing. Fans and vents may be installed on the roof system that will draw the air out of the attic space and exhaust it to the exterior. Make sure there is air flow from the eaves. Window fans are especially useful for this purpose.

However if your attic has blocked soffit vents and is not well sealed from the rest of the house attic fans will suck cool conditioned air up out of the house and into the attic. You need to circulate massive quantities of air over anything that is hot because there is no water available to increase the rate of heat transfer. Attic fans are intended to cool hot attics by drawing in cooler outside air from attic vents soffit and gable and pushing hot air to the outside. Cover all your skin to protect it from the itchy insulation and wear a dust mask.

Soffit vents may leave air trapped at the top of your attic. Intake vents located at the lowest part of the roof under. These fans may be controlled by a switch or a thermostat which detects heat build up in the attic space and automatically exhausts the attic space. Grab a flashlight and inspect your attic during the winter.

All of these objects radiate the heat just like the glowing coals in a campfire. If the soffit of your home isn t perforated to allow air movement either replace it with perforated soffit or install round air vents under the eaves to allow air flow. There are many ways to improve your home s air circulation from the simple solutions like opening doors and windows to installing a whole house system in your attic. If your attic doesn t have a walkway take two small 2 x 4 ft sheets of 1 2 in.

Cool air in hot air out attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents. Warm air that escapes rooms below gets trapped in the attic. Warm moist air trapped in the attic condenses and freezes on the wood.
