Circulate Air In Attic

Here are the signs to look for.

Circulate air in attic.

Cool air in hot air out attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents. Frost on the underside of the roof or rafters. Gable vents may circulate air through only a small percentage of your attic. 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.

Make sure there is air flow from the eaves. 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. The only way to lower the attic temperature is to pass air over the lumber and insulation lots and lots of air. 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. Warm moist air trapped in the attic condenses and freezes on the wood. If your attic doesn t have a walkway take two small 2 x 4 ft sheets of 1 2 in. 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. 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. 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. Warm air that escapes living space also carries moisture that will condense on rafters or roof sheathing.

Snow melts and the water refreezes on the cold eaves creating ice dams. Warm air that escapes rooms below gets trapped in the attic. This is normally the point where air enters your attic. Window fans are especially useful for this purpose.

Whole house fans powered attic fans. 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. Ventilation systems help circulate the air in and out of your home and importantly also make sure that air keeps moving through different areas inside your home. 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.

Plywood to move around on. 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. Cover all your skin to protect it from the itchy insulation and wear a dust mask.
