Insulating the attic is important for keeping your house warm and cool at the same time. When we are attempting to keep the house warm during the winter, we consider whether additional insulation in the attic would be beneficial. The crucial role that attic insulation plays in keeping the home cool during the hot summer months is something that we frequently overlook.

One of the most cost-effective ways to maintain comfort, conserve energy, and save money is to insulate the attic. The warm air your warming framework produces and the cool air your A/C gives loves nothing better compared to getting away from through our lofts.


If you’re having trouble keeping cool this summer without running your air conditioner round the clock, adding insulation to your attic may be your most important retrofit.

Adding insulation to your attic won’t always result in the comfort, energy savings, and lower utility bills you want. Like everything else in the home retrofitting industry, success can only be achieved by doing things correctly.


To successfully install insulation and maintain a cool home, follow these eight steps.


  1. First, air seal the ceiling:

The insulation layer slows down the transfer of heat from one side to the other. That’s good because it takes a long time for the warm air on one side to mix with the cold air on the other side through the insulation. Insulation is effective at slowing heat transfer, but it is not as effective at slowing air currents, particularly when the air is pushed through the insulation due to stack effect, pressure difference, or the predominant wind.

The insulation loses some of its value once air currents pass through it. The insulation is unable to carry out its intended function. Air seals the ceiling holes first before insulating the attic. Air seal those roof entrances made by handymen, circuit testers, central air, and fireplaces.


  1. The Attic Should Be Pre-Wired for Both Current and Future Technology:

I’ve been in a lot of attics, and I’ve seen how the insulation gets destroyed when every security professional, internet provider, satellite dish installer, phone company connector, and exterminator finishes walking and crawling through the attic.

They don’t care about your insulation; all they care about is getting you connected. You won’t have many R-values left after six men in boots march up there and flatten all of the fluffy, loose fill and blown-in insulation.

Pre-wire the attic if you can and be prepared for technology. If internet-based installers must enter the attic, instruct them to leave it as they found it. In the event that you packed it, cushion it back up before you leave.


  1. Ensure ventilation in the attic:

If you don’t believe me, an attic needs to breathe. If not, it becomes an oven. I’m certain you know what I’m talking about, you have experienced the broiler influence various nights in the course of your life.

It operates as follows:

It’s a splendid radiant day and the warm beams of the sun beat down on the rooftop the entire morning and throughout the evening. The temperature in the attic space fluctuates between warm and scorching. The attic’s scorching temperatures begin to spread through the ceiling around 4 p.m., warming the living room. The house keeps getting hotter and hotter as the sun



You open the windows and doors as the weather outside starts to cool down, but the attic keeps cooking. You try to fall asleep with ice water next to your bed and a cool, damp washcloth on your forehead.


You can find out how much ventilation your attic needs from the city building departments. They’ll say that for every 100 cubic feet of attic space, you need so many square feet of open ventilation. My recommendation is to provide more ventilation in the attic than the minimum required.


Why not offset your attic oven with ample attic ventilation? The more people you have, the better.


  1. Install the solar exhaust fan in the attic:

No one I’ve spoken to is unhappy with their solar-powered attic exhaust fan. One way to truly turn off the oven is this. According to the homeowners, the fans really help prevent the attic from heating the living room at night.


At the point when the sun stirs things up around the town cluster mounted right on the fan cover, the fan begins to turn coaxing sweltering air out of the storage room. The air is then supplanted by cooler air that enters the upper room along the lower part of the rooftop. Cooler air enters from the oven.


  1. Install Tubes for Solar Lights:

Why not put in one or two solar tubes and then add more insulation to the attic instead of insulating it and making it harder to get into it? Solar tubes are a great way to bring natural light into a room with no other light source than a light bulb.

Hallways, bathrooms, utility rooms, entryways, closets, garages, and kitchens are all popular locations for installing solar tubes. A room that you might want dark during the day is about the only place where a solar tube would not work well. For example, a bedroom for the graveyard worker.

Make sure to air seal the opening that allows the solar tube to pass through the ceiling if you install one. Connect the tube to the ceiling.


  1. Electricity and lighting:

While you’re getting ready to add upper room protection, adding loft lights and a plug or two may be helpful. This not only helps you during the retrofit of the insulation, but it can also help the electronic boys when they enter your attic to provide you with the best high-definition image possible.

The electric outlet and light switch are close to the attic access cover.


  1. Spray Foam to Get the Best Results:

Although the insulation that covers the floor of the attic does a good job of keeping the indoor climate separate from the climate in the attic, spraying foam insulation on the underside of the roof sheathing can be very helpful if you really struggle to keep the attic from becoming an oven.

Although spray foam insulation is more expensive than cellulose or fiberglass, it protects the insulation’s source. It significantly reduces heat transfer between the roof and attic by being applied to the underside of the roof sheathing.


  1. Seal the cover for the attic access.

The majority of covers for attic access simply do not fit well. The amount of air that moves through the cover during a blower door test is usually very obvious. Quantifying the amount of leakage with the smoke stick and infrared camera is easy.


Similar to door weatherstripping, air sealing the cover is done in the same way. Between the two surfaces that are next to each other, a flexible material like foam is placed. Now, the trick is to latch the cover to the ceiling in a way that makes the weatherstripping slightly squeezed.

Insulating the attic may be your best secret weapon against having a pooped out air conditioner in Texas, so don’t think of it as something that is best suited for the cold winds of North Dakota.

Gotten along nicely, protection can hold the stove in your storage room back from attacking the living space beneath. You might be able to finally fall asleep if you keep the bedroom cool enough.


Thank you for coming by; I hope to see you soon; however, I won’t leave the light on… Different Attic Insulation Options Have Different Benefits and Drawbacks Attic insulation has a significant impact on how well a home uses energy. In point of fact, the majority of building scientists concur that the attic ought to be the initial “target” area for upgrades to air-sealing and insulation. The majority of homes are constructed with attic insulation levels far below current U.S. Department of Energy recommendations, which are required by code. of Power.


There are a variety of options available to homeowners considering upgrading their attic insulation. Every storage room protecting choice enjoys particular benefits and restrictions. Choosing the best upgrade to your attic’s insulation can be made easier if you know these benefits and drawbacks.


Insulation made of fiberglass batts is popular due to its low cost and universal availability. Fiberglass batts are used to insulate attics in many homes, regardless of age. Unfaced batts are more prevalent in attic installations than faced batts, and the batts are typically installed between attic floor joists.


PROS: More reasonable than different kinds of storage room protection. Best insulation for do-it-yourselfers to install. Batts, like lights and ceiling-mounted vent fans, can be moved to gain access to the ceiling below, unlike blown insulation. When blown insulation is added to an attic, the attic’s overall R-value can often be increased without changing the batt insulation.


CONS: Challenging to introduce accurately around hindrances. Insulation-deficient voids result in significant energy loss. In most areas of the country, multiple layers of batt insulation are required to achieve the recommended R-values; Because of this, storage can’t be done in the attic unless special platforms are built before insulation is put in. Insulation made of fiberglass can’t stop airflow.
