When your attic is not properly insulated, it becomes very easy for cold and heat to make way into your interior.

Excessive heat and cold can only be regulated by air conditioners and heaters; when you have more heat or cold coming into your interior, the heater and air conditioner will have to work harder to make your atmosphere comfortable.

Energy costs are driven up when your heater and air conditioner work harder, so, you need to insulate your attic to reduce energy consumption and energy cost.

Even when you use thermostats and your attic is not insulated, you may not get the temperature of the room to be the exact temperature setting you chose.

Together with your attic insulation, you will also have to insulate your floors and crawl spaces if you want to reduce your energy consumption to lowest possible.

Increases indoor comfort

When you attic is under-insulated or uninsulated, cold and heat will exit and enter easily causing temperature fluctuations.

The heating and cooling will struggle to cope with these temperature changes and the atmosphere of your interior space will become uncomfortable.

With your attic insulated, you will be able to maintain consistent temperature in your interior, because hot and cold air will be prevented from just coming in and going out; the atmospheric condition outside will not easily influence the temperature of your home interior.

Reduces noise

In addition to ensuring steady temperature, attic insulation can also reduce the noise disturbance coming from your surroundings.

There are many things and activities all around you that cause noise that can be very annoying when you are trying to concentrate on something or trying to get some rest.

On their own, roof shingles also have the function of reducing noise but there is a certain level to which they can reduce noise.

Attic insulation will further reduce the noise, making sure that you experience no disturbance.

Improves the quality of indoor air

Without insulation in your attic, there are bound to be air leaks through which dust, dirt, and other pollutants will get into the interior space.

When the flow of these pollutants into your home reaches a certain level it begins to reduce the quality of your indoor air.

For people who have asthma, allergies or other respiratory issues, it is important that the air is free from all these agents that can trigger attacks.

Attic insulation will go a long way in preventing pollutants from getting into your space.

It will also eliminate the cost of buying an air purifier to remove dust and allergens from you indoor air.

Reduces HVAC wear and tear

Without attic insulation, your heater and air conditioning systems will have to work harder to try to maintain comfortable temperatures.

This leads to quick wear and tear of your heating and cooling systems.

However, when there is proper insulation, hot or cold air won’t move in and out, so the heater and conditioner will work less in maintaining a constant temperature.

Types of attic insulation

If you have never insulated you attic or if your attic is under-insulated, you need to carry out proper insulation for the reasons discussed above.

Whenever you are ready to insulate your attic, there are three common types you can choose from; these three types of attic insulation are discussed below.

Blown-in insulation

This is the cheapest attic insulation you can get, however it is not the most popular.

Basically, blown-in insulation is blown out of a blowing device, and it attaches easily to any surface it comes in contact with.

This type of insulation should only be installed by a professional; there are specific tool that are used for the insulation which an average homeowner may not have.

Sound rated insulation

If you are always experience noise disturbance from your surrounding and you want to reduce the noise getting into your interior space, you should consider this type of insulation.

Typically, sound rated insulation is made from mineral wool; this material doesn’t allow sound to pass through it and it is also fireproof.

With this type of insulation, you protect your home form temperature fluctuations and noise disturbance.

Blanket insulation

Even though blown-in insulation is the cheapest type of insulation, blanket insulation is the most common one there is.

This type of insulation is also known as Batt insulation and it is made from a mixture of plastic, fiber glass, and some other materials.

It is easy to fasten to ceiling and even walls; this may be the reason why it is the most popular attic insulation.


Houses without attic insulation are not many, however, there are a lot of houses that have under-insulated attics.

In homes with under-insulated attic and no attic insulation, air leaks are unavoidable; with hot and cold air air moving in and out, it will be hard to maintain a stable temperature inside.

Even with heating and cooling systems, temperature control will be hard because the exterior temperature is able to influence the interior temperature as hot or cold air moves in or out of through the attic.

Three common types of attic insulation have also been discussed so you can know about the options available to you whenever you are ready to insulate your attic.
