Quick Answer: How To Keep Attic Warm In Winter

How Can I Keep My Attic Warm In The Winter? Block windows. Just like you’d use heavy drapes to block the cold in your living room, it’s necessary to cover areas where leaks promote temperature shifts. Insulate the space. Extend your ductwork.

Why is my attic so cold in the winter?

Many attics contain ductwork that supplies cool air to upstairs rooms during the summer and heated air during the winter. If the joints in your ductwork are not properly sealed, your forced air system can suck attic air into the ducts –air that’s either really hot in the summer or really cold in the winter.

How can I heat my attic in the winter?

Other effective ways to heat your attic include baseboard heaters or space heaters. Both of these solutions might require running electricity to the attic. Do not run extension cords from the floors below to your attic. Monitor the use of baseboard and space heaters to prevent any chance of a fire.

How can I keep the heat in my attic?

Install electric ventilators and attic fans, which remove hot air from an attic. They have thermostats that turn the fan on at a recommended preset temperature of 100-110 degrees. Alternatively, install passive vents such as gable, soffit and ridge vents, which are openings in the roof that allow hot air to escape.

How do I keep my attic from freezing?

Insulate pipes located in the attic and crawl space using pipe insulation, even if the climate where you live does not often have hard freeze conditions. You can also wrap pipes in heat tape or heat cables with a thermostat control.

What is the ideal attic temperature?

The ideal attic temperature should be no less than 60 degrees in the winter and no more than 10 to 20 degrees above the outdoor temperature in the summer. If your attic temperature climbs above 130 degrees, you may start running into issues with your energy bill, as well as the integrity of your roof.

Should I leave my attic door open in winter?

— Dan W. J.D.: People seldom think about it, but the attic access opening can account for a significant loss of heat from your home during winter. This loss is a combination of heat flow through the uninsulated cover and warm air leakage where it rests on the molding.

Should attic be vented?

When done correctly, attic venting can reduce the potential for condensation in winter and summer. Even when outside air is hot and humid, if the attic space is air-sealed from the interior, it is much hotter than outside air. The hotter the air, the more moisture (i.e. absolute humidity) the air space can hold.

Will insulating my attic make my house warmer?

Insulating an attic will make your home feel more comfortable. You’ll feel warmer in the winter and cooler in the summer. Plus, by replacing old insulation or installing new insulation in an unfinished attic you’ll save money on cooling and heating bills in the long run.

How much heat do you lose through your attic?

As much as 85 percent of the heat lost in a house passes through the attic. In fact, the U.S. Department of Energy estimates that boosting attic insulation can lower heating costs by 10 to 50 percent (depending on the current level of insulation).

How hot is an attic on a 100 degree day?

Thanks to the radiant heat affect, attic temperatures on a 100-degree day can reach 170 degrees or more.

Can I put a regular fan in my attic?

Attic fans do really work. They will help to circulate air in your attic and ventilate the space so that it stays closer to the outside temperature. Attics can reach extremely high temperatures in hot, summer months and gather an excessive amount of moisture in the winter. Attic fans will help fight these problems.

How hot is an attic on a 90 degree day?

More often than not, attic temperatures will be in excess of 125 degrees on a 90 degree day. This will overwork your air conditioning equipment, run up your utility bill and shorten the life of your roof. Ridge vents help – excessive heat can escape through ridge vents.

Should water pipes in attic be insulated?

Because most attics are unconditioned, a hard freeze that plunges attic temperatures into the mid-20s for any length of time can cause a burst pipe. Insulate exposed pipe. Wherever water supply lines pass through the attic, foam pipe insulation sleeves should be installed on all exposed spans.

Will water pipes freeze in attic?

Pipes in attics, crawl spaces and outside walls are all vulnerable to freezing, especially if there are cracks or openings that allow cold, outside air to flow across the pipes.

Does foam pipe insulation prevent freezing?

Pipes can be fitted with foam rubber or fiberglass sleeves to help decrease the chances of freezing. Insulation can help keep a pipe closer to the temperature of the water inside the pipe, but it does not add heat to the pipe and will not prevent freezing if the pipe is exposed to prolonged freezing temperatures.

How often should attic fan run?

Generally speaking, an attic fan should run as long as it takes to replace all the attic air with outside air. Usually, this takes roughly 15 minutes. However, you can calculate a much more accurate time by dividing the strength of your fan by the volume of your attic space.

What should my attic fan be set at?

When it comes to an attic fan’s temperature setting, it’s best to adjust it to anywhere from 90 to 110 degrees Fahrenheit. It’s impossible to state a single number because your attic can effortlessly soar above 95 degrees (on average).

What should attic humidity be in winter?

If there is too much moisture in your attic, it will condense on the upper portion of your roof deck which rusts the exposed nail, rots the deck, and could inspire mold to grow. Throughout winter, your home should have about a 35% to 40% humidity level.

What happens if attic is not vented?

But in homes without appropriate insulation and ventilation in the attic, heat migrates. Meanwhile, because hot air is full of moisture, all that water hanging out in your attic is causing condensation to build up. Excess heat and condensation can cause major damage to your roof and roofing materials.

How do you tell if your attic is properly ventilated?

How to determine whether you need better attic ventilation Look at your eaves and roof. Touch your ceiling on a warm, sunny day. Thick ridges of ice on your eaves in winter are a sign of poor attic ventilation. Warm air that escapes living space also carries moisture that will condense on rafters or roof sheathing.

Can I put a box fan in my attic?

A box fan sucks air from its back and propels it forward. This makes it well suited to substitute for an attic fan, and you can install it yourself. No extensive remodeling of the attic must be done, since you will be able to use an existing attic vent.
