How to Keep Your Attic Cool in Summer? If you’re like most Americans, your attic can get awfully hot during the summer, leading to an increase in your energy bill and an uncomfortable living space. To combat this problem and keep your attic cool all summer long, try these helpful tips for reducing heat in your attic in summer time.
Keeping your home cool during the summer is a priority for most homeowners. But if you have an attic that’s also hot, it’s important to learn about the types of things you can do to make sure it stays as cool as possible. After all, by cooling down the attic, you can prevent issues like mold and mildew from developing throughout the rest of your home.
An effective way to keep your attic cool in summer is to add more ventilation in the form of gable vents and ridge vents on either side of the roof. You may also want to consider installing ceiling fans or even using solar-powered fans on top of your roof shingles so that they pull heat away from inside your home instead of trapping it under those same shingles (and causing a whole lot more problems!).
Why Do Attics Retain So Much Heat?
An attic is a very active place. It is full of vents and air ducts, and it retains heat from the sun, which in turn heats up the air trapped there. When you consider these facts, it’s easy to see why attics are hot.
We mean, the answer is simple. As much as one-third of your home’s heat gets trapped in your attic, making it hotter than it should be. And that’s not just a problem during summer months—it also means you’re wasting money heating an area that’s not being used for living space.
However, you can make sure that your attic stays cool by sealing gaps around air ducts or simply insulating them with fiberglass mesh cloth insulation. You can also install a fan in the ceiling area of your attic so that when it blows warm air out of your home through an opening at the gable end or roof peak of an attic space it will suck cooler outside air into your house through those same openings.
What happens if your attic got too hot?
If your attic is hot, you will not be able to sleep well. You cannot concentrate on anything and it is almost impossible to cook in such conditions. It is even more difficult when the temperature goes up more than 30 degrees Celsius.
In addition, the risk of fire increases significantly when temperatures rise above 35 degrees Celsius and become unbearable for most people who live there.
The excess heat can also make your attic a health hazard as it leads to dehydration and body overheating which may lead to heat exhaustion or even brain damage if left unattended for too long without proper treatment (elevated body temperature).
Finally, keeping an attic at high temperatures will reduce its insulation value which means higher costs for cooling or heating systems that should be installed in order for them not being damaged by excessive warmth inside their premises if left unattended long enough due to lack of care on behalf of homeowners who do not take care about their properties properly at all times during summertime weather conditions like these ones where we live now!
Tips On How To Lower Attic Temperature
1. Air Sealing
As much as 30% of the air that leaks into your home does so through the attic. This can lead to higher energy bills and make your home less comfortable. Air sealing your attic is a great way to improve your home’s energy efficiency and comfort.
What is Air Sealing?
Air sealing is the process of making a home airtight in order to prevent drafts moisture and pests from entering. Air sealing is usually done with weather stripping caulk and other materials that can fill gaps and cracks. Air sealing can be used on both new and old homes.
Air sealing your attic is the process of preventing air from leaking through cracks and holes in the walls, ceiling, and floors of your home. It reduces the amount of air that escapes from the home, which reduces the amount of energy required to cool the home. Air sealing also helps prevent moisture buildup in attics by keeping out moisture-laden air.
How Air Sealing Cools Your Attic?
Airtightness is the key to a cool attic. By sealing all of the cracks and gaps in your attic you can prevent hot air from entering and prevent cool air from escaping. This will keep your attic cooler which will in turn keep your home cooler.
How to Air Seal Your Attic?
Air can enter a house through several common areas: around windows; between utility lines and framing members above ceilings; at attic floor vents; under door jambs or sills; and gaps around chimneys or flues.
To air seal your attic you’ll need to identify all of the gaps and cracks where air is leaking in. This includes around electrical outlets light fixtures plumbing pipes and ductwork. Once you’ve identified all of the leaks seal them with caulk or weather stripping. For bigger gaps you may need to use expanding foam insulation.
Now, you can seal your attic using a variety of methods.
- You can use insulation and sealing materials to cover the gaps between the floor joists and the roof rafters, as well as any other places where air is seeping into your attic.
- You can also use spray foam insulation for this purpose. Spray foam is easy to apply and will fill in all those tiny gaps between the ceiling joists and roof rafters, reducing how much heat transfers from inside your home into your attic during summer months.
- You can seal your attic yourself with caulk or weather stripping.
- Or you can hire a professional to do it for you.
Air sealing your attic can be a big project but it’s worth it for the energy savings and comfort it provides.
2. Attic Insulation
If you’re looking for a way to keep your attic cool in the summer, installing insulation is a great place to start. Insulation is generally inexpensive and easy to install, but it’s also an effective way of keeping heat out of your house and letting cool air flow through the attic more easily.
Without insulation, the heat from the sun can quickly build up in your attic, making it extremely hot. This can cause your air conditioner to work overtime to try to keep your home cool, which can lead to higher energy bills.
What is Attic Insulation?
Attic insulation is one of the most important things you can do to improve your home’s energy efficiency. By insulating your attic you can keep your home’s heat in during the winter and out during the summer. This will help you save money on your energy bills and make your home more comfortable year-round. There are a variety of attic insulation products on the market so it’s important to choose the one that best fits your needs.
How Insulation Cools Your Attic?
Insulation works by creating a barrier between the hot air outside and the cooler air inside your home. This barrier helps to keep the heat from the sun from entering your attic, and it also helps to keep the cool air inside your home from escaping. This makes it much easier for your air conditioner to keep your home cool, and it can also help to reduce your energy bills.
There are a variety of different types of insulation available, and the type that you choose will depend on a number of factors. The climate in your area, the type of home you have, and your budget will all play a role in choosing the right type of insulation for your needs.
If you are not sure which type of insulation is right for your home, you can always consult with a professional. They will be able to help you choose the right type of insulation and install it properly, ensuring that your attic is cool and comfortable all summer long.
How to Apply Attic Insulation?
Wear a dust mask and gloves to avoid itchiness and irritation from the insulation fibers.
Start by measuring the width and length of the attic floor then calculate the square footage. This will tell you how much insulation you need to buy. There are three main types of insulation: fiberglass batting, loose-fill fiberglass and cellulose (recycled newspaper). Fiberglass is the most common type of attic insulation and it comes in rolls or pre-cut batts. Loose-fill fiberglass is blown into place with a special machine while cellulose is sprayed in place.
Once you’ve selected your insulation install it between the floor joists with the paper side facing down. Cut the insulation to fit snugly so no gaps exist to the outside. Attach the insulation to the floor joist using either nails or plastic staples. Test for leaks in the walls and floor of your attic. Start by sealing any cracks you find with polyurethane caulk using a caulking gun.
Or, alternatively, you can follow the following steps too!
The first step in attic insulation is to remove your existing insulation and dispose of it properly. This can be done by pulling out the old material, which may be batts or loose fill. If you are insulating with a foam board, rip up any old fiberglass insulation that has been installed over these boards. Once the old insulation is removed, check for air leaks and seal them before installing new materials.
After sealing all air leaks and venting areas, install new insulation on top of your joists at 16-inch intervals down their length (whether they are 24 or 48 inches apart). You should have enough space between each piece of batt so that there is room for vapor barriers as well as sheets of plywood if necessary for structural strength.
Use 1-1/2 inch thick extruded polystyrene (XPS) panels if possible because they provide better R-values than 2-inch XPS panels; however 2″ XPS will work well for this purpose as well so long as it does not exceed 3 feet long before being cut into sections suitable for installation between rafters or trusses below them instead using full sheets – otherwise you may end up wasting some product when cutting large sheets down into smaller pieces later on which could cost more money than buying smaller sized ones upfront.
3. Attic Ventilation
What is Attic Ventilation?
Attic ventilation is the process of providing fresh air to the attic space in order to remove heat and moisture. This is typically done with a combination of exhaust fans and intake vents. The most common type of exhaust fan is the gable fan which is installed in the gable end of the attic. Intake vents are typically installed along the soffit or eave line. Attic ventilation helps to keep the attic space cooler in the summer and drier in the winter which can help to extend the life of the roof.
How Attic Ventilation Cools Your Home?
Attic ventilation is one of the most important aspects of keeping your home cool in summer. By circulating air through the attic, it helps to remove the hot air that can build up and make your home uncomfortable.
How to Ventilate Your Attic?
There are two main ways to ventilate your attic in summer: natural ventilation and mechanical ventilation. Natural ventilation relies on convection to circulate air, while mechanical ventilation uses fans to move air.
Natural ventilation is the most energy-efficient way to ventilate your attic, but it requires careful planning. You need to ensure that there are enough openings to allow air to flow freely, and that the openings are positioned to maximize cross-ventilation.
To allow the air to flow freely you can use soffit vents. These vents are installed in the soffits (the space between the edge of the roof and the fascia) and allow air to flow into the attic.
You can also use gable vent. A gable vent (or ridge vent) is another type of ventilation device used on residential roofs to allow heated interior air from an unvented attic space exit directly through an opening at or near ground level while simultaneously providing an intake for fresh outdoor air into this same area so as not create any pressure imbalances between them (like those caused by chimney drafts).
Mechanical ventilation is more expensive to operate, but it can be more effective in circulating air. If you choose to use mechanical ventilation, make sure to select a fan that is specifically designed for attic ventilation. These fans help to draw the hot air out of the attic and replace it with cooler air from outside.
These fans works by drawing cooler air from outside through the foundation into the house and pushing hot air out through the gable end of your home’s roofline where it exits into the atmosphere or down into a lower level of your home depending upon how you have configured your system.
You can use a fan, solar powered attic fan and an attic venting kit. A gable fan is another good option for ventilating your attic. A power attic ventilator or power ventilator will also work well in this case. Using a power attic vent could be one of the best options for you if you want to take care of the problem yourself without having to hire someone else who does not know how to do this or what exactly it takes to make sure that we have proper ventilation in our homes during summer months when it gets extremely hot outside and temperatures inside may reach up towards 100 degrees Fahrenheit or higher depending on where you live.
Whichever method you choose, regular maintenance is essential to ensure that your attic is properly ventilated. Inspect your ventilation system regularly to make sure that it is clean and in good working condition.
4. Install radiant barriers
Radiant barriers are a type of insulation that helps keep your home cool in summer and warm in winter. They work by reflecting heat away from your home, which keeps the inside temperature comfortable.
Radiant barriers are made of a variety of materials, but most commonly, they are made of aluminum foil. Aluminum foil reflect the heat that would have otherwise been absorbed by the attic. They’re effective for temperatures above 80 degrees F, and they can be installed on the roof or walls of the attic.
Installing a radiant barrier in your attic is a great way to keep your home cool in summer. Radiant barriers reflect heat away from your home, which helps keep the inside temperature comfortable. Radiant barriers are made of a variety of materials, but most commonly, they are made of aluminum foil. Installing a radiant barrier is a relatively simple process, and it is a great way to improve the energy efficiency of your home.
5. Install Attic Fan
If you want your attic to stay cool in the summer, one of the best things you can do is install an attic fan. Attic fans are designed to exhaust the hot air that builds up in your attic, and they can make a big difference in keeping your home comfortable.
There are a few things to keep in mind when you’re choosing an attic fan, though. First, you’ll need to decide whether you want a gable-mounted fan or a roof-mounted fan. Gable-mounted fans are easier to install, but roof-mounted fans are more effective at exhausting hot air.
Second, you’ll need to consider the size of the fan. The larger the fan, the more air it will be able to move. However, you’ll also need to make sure that the fan is the right size for your attic space.
Finally, you’ll need to decide how you want to control the fan. Some attic fans are controlled with a switch, while others have a thermostat that turns the fan on when the attic temperature reaches a certain point.
Attic fans are often used along with other types of cooling systems such as central air conditioning units and window units because they work best if they have plenty of ventilation around them so they can bring fresh air into the attic while also pushing hot air out through vents at the top of the home’s walls.
Installing an attic fan is a great way to keep your attic cool in the summer. Just be sure to choose the right size fan for your space and decide how you want to control it.
6. Add reflecting roofing
Adding a reflecting roof to your attic is a great way to keep it cool in the summer, while also saving on energy costs. The reflecting roof will reflect the heat away from the attic, keeping it cooler.
There are different types of reflective roofing such as aluminum panels or steel sheets which have an aluminum coating on them. If these materials are added to your home’s ceiling then it will help to keep your house cool during summer months as well as winter months because it reflects sunlight as well as heat back into space where there is less temperature variation in comparison with ground level temperatures.
7. Clean the Vents
Check your vents first. If they’re covered with insulation, dirt or leaves, it could be a major culprit of heat building up. You’ll have to completely remove any blockage before you can reap any benefit from cleaning them.
Once you’ve got clear vents, use a household appliance cleaner or compressed air to get rid of any dust or cobwebs that may be inside. If there is still some amount of condensation around your ducts that doesn’t seem to go away despite keeping them clean and dry, apply some weather-stripping tape over where they come into contact with your home—this will help prevent moisture from getting into your ducts in future as well as keeping cool air from escaping.
8. Seal the Windows
By sealing your attic’s windows you can reduce airflow and help keep heat outside. Make sure all windows are well-fitted and tight, particularly if they have old weather stripping or look like they could have air leaks.
Use caulk or foam sealant to cover any open gaps around window trim, but be careful not to let it drip down into your living space. It’s also a good idea to cover any screens with metal mesh so mosquitoes don’t make their way into your attic during warm months.
To further prevent heat from entering your home, you can paint your roof white—it will reflect more sunlight than darker colors (which absorbs more).
9. Use a Dehumidifier
The first step is choosing a dehumidifier that’s appropriate for your space. Most are pretty small (around 50-pounds) and can easily be moved around so you can keep it out of your way when not in use.
10. Put Up A Shade or Blinds
While you might think of your attic as a dark, cobwebby storage area, it’s also an excellent place for hot air to build up during summer months. If your home doesn’t have central air conditioning, putting up blinds and shades can do wonders to keep heat at bay. You should also consider installing attic fans and replacing any window seals that are broken; these simple additions can save you a bundle on electricity costs and lower temperatures significantly.
11. Close Down Rooms You Don’t Use
Some rooms, like your laundry room and garage, likely aren’t used much during summer months. If you’re not using those rooms, close them off so they don’t add heat to your attic. This also includes your bedroom if you sleep with your door closed; keep it open at night so that cool air can circulate throughout your home. Since ceiling fans run off of electricity and create air circulation, putting one in an unused room will help distribute cool air evenly throughout your home.
12. Schedule an insulation check-up with a professional.
Insulation is the key to keeping your attic cool in summer. Your home’s cooling system includes insulation, ductwork and air conditioning. Insulation is the most important element of your home’s cooling system because it has a direct impact on how much heat escapes from your house through cracks and other openings. In fact, it’s estimated that as much as 50% of all heat loss from homes occurs through the attic area!
Keeping in mind that insulating properly can help save you up to 30% on cooling costs during hot weather months (and 15% during milder months), this is clearly an important step toward keeping cool without breaking the bank. If you’re ready to learn more about how you can increase the energy efficiency of your home with proper insulation, read our article on proper insulation installation practices here!
13. Try to keep the furnace away from your attic.
If you have an attic, there’s a good chance that it’s hot and stuffy up there in the summertime. If you can’t move your furnace away from your attic, then there are some steps you can take to try to keep it cool.
First of all, make sure that your furnace is not exhausting heat into the attic. This is easy to check: just look at the ducts leading from your furnace into your home and make sure they’re not hanging down into the space above where people are going to be spending time (like bedrooms).
Next up: if possible, move or relocate your furnace (or air conditioning unit) so that it’s not directly above anyone’s bedroom or living area. Again—this sounds like an unlikely scenario but if this is something within reason for you then it might be worth looking into!
If You Want To Beat The Summer Heat, Focus On Your Attic And Its Features.
If you want to beat the summer heat, focus on your attic and its features. The attic is the hottest room in your home during summer months. This happens because it’s the only part of your house that doesn’t have a roof over it, so sunlight can easily get in there and heat it up.
The problem is that most attics are full of insulation as well as other stuff like ductwork or pipes which make them even hotter than they should be – trapping heat inside them.
If you want your attic to cool down, follow these steps. Air seal the vents of your attic so that the hot air does not enter it. Get proper insulation and vent fans so that air circulation is good enough in your attic. Install radiant barriers in the attic to let it cool down. Install Attic Fan in the attic to let it cool down. Cover your roof with reflective roofing material to prevent heat from entering your house through the roof and keep your attic cool during summer days.
