Why Upgrading Your Attic Insulation Is Key To A Comfortable Home?

Does your home become too hot in the summer and too cold in the winter? If so, it might be time to upgrade your attic insulation. Good attic insulation is key to having a comfortable home, no matter what the temperature is outside. Here’s what you need to know about attic insulation and its importance. 

The Importance of Attic Insulation 

Attic insulation serves two primary purposes.

First, it keeps your home warm in the winter and cools in the summer. In the winter, heat rises and escapes through the roof if there’s not enough insulation. It makes your home less comfortable and can potentially drive up your energy bills as your heating system must work overtime to compensate for the heat loss. 

Second, heat from the sun can enter your attic and make your home uncomfortably warm in the summer. Again, this strains your cooling system and drives up your energy bills. 

How Upgrading Your Attic Insulation Can Improve Your Home’s Comfort Level?

When it comes to home comfort, your attic plays a key role. In the winter, heat rises, so if your attic isn’t well-insulated, that heat will escape through the roof. The result? Your home will be colder, and you’ll have to crank up the thermostat to compensate, which can drive up your energy bills. 

On the other hand, the sun beats down on your roof during the summer, causing the temperature in your attic to rise. Once again, if your attic isn’t properly insulated, that heat will seep into your living space, making your home uncomfortable. That’s why ensuring that your attic is adequately protected is essential. Here are some of the benefits of doing so.

  1. Improved comfort: Both in the winter and summer, upgrading your attic insulation will help to regulate the temperature in your home, making it more comfortable for you and your family. 
  2. Lower energy bills: By trapping heat in the winter and keeping cool air during the summer, you can drastically reduce your energy consumption, leading to lower energy bills. 
  3. Enhanced durability: Along with helping to regulate temperature and saving you money on energy bills, proper attic insulation can also extend the life of your roof by protecting it from extreme temperatures. 
  4. Improved indoor air quality: By sealing gaps or cracks in your attic, you can help prevent outside air contaminants from entering your home and impacting your indoor air quality. 

Types of Attic Insulation 

There are three main attic insulation types: fiberglass batts, spray foam, and blown-in cellulose. 

Fiberglass batts are the most common type of attic insulation. Its material is made from glass fibers, spun into a mat, and bonded with resin. It is one of the most common types of insulation used in attics. They’re made from recycled glass bottles and other materials and are easy to install. However, one downside to fiberglass batts is that they can settle over time, leaving gaps in the insulation. 

On the other hand, spray foam is a newer type of insulation made of polyurethane foam sprayed into place. It expands and hardens to form a barrier against heat loss and heat gain. It’s also one of the most effective types of insulation for reducing drafts and improving comfort levels in the home. However, spray foam can be more expensive than other types of attic insulation.

Finally, blown-in cellulose is from recycled paper treated with fire retardants and blown into place with a particular machine. Cellulose is from recycled newspapers and other paper products and is treated with fire-retardant chemicals for safety.

It’s also environmentally friendly since it recycles materials that would otherwise end up in landfills. However, one drawback to cellulose is that it can be more challenging to install than fiberglass batts. 

Choosing the Right Type of Insulation for Your Home 

The type of insulation you choose will depend on several factors, including the climate you live in, the kind of home you have, and your budget. 

For example, if you live in colder weather, you’ll need more insulation than in warmer weather. The amount of insulation you’ll need will also depend on the type of home you have. 

A well-insulated house will need less than an inadequately insulated home. If you need help choosing the right type of insulation for your home, don’t hesitate to call our Bay Area attic insulation contractors.
