Do you have an attic that needs to be insulated? Are you wondering how much it will cost to insulate your attic? In this blog post, we will provide an estimate of the cost to insulate an attic in 2023. We will also provide some tips on how to save money when insulating your attic.

The cost of insulating an attic is influenced by a variety of factors

Insulating your attic is a great way to save on energy costs. Depending on the size of the attic, type of insulation and R-value you choose, it can cost anywhere from a few hundred dollars to several thousand dollars. The average cost of insulating an attic is $2,500, but it is a great long-term investment. Larger attics require more materials, while higher quality insulation comes at an additional cost. It’s important to do your research before investing in attic insulation as this will help ensure you get the best product for your specific needs and space. Additionally, because it’s such a significant investment, homeowners should also explore any energy efficiency subsidies/incentives that are available in their area.

The most common type of insulation is Fiberglass

When insulating a home, fiberglass is often an ideal choice due its affordability and ease of installation. Fiberglass is among the most efficient materials for insulation. It also has the added benefit of making it more difficult for outside sound to penetrate the walls and ceilings of your home, providing greater acoustic comfort while also improving the energy efficiency of you house. A typical 1,000 square foot attic will require 30 to 40 bags of fiberglass insulation, costing between $200 and $300. All in all, preparing your attic for winter doesn’t come cheap – but by doing so, you’ll be able to save money further down the line through lower heating costs.

What are some other insulation options?

If fiberglass doesn’t fit your needs, there are many other options to choose from. Cellulose insulation is made of recycled paper fiber and works well for attics, walls, and floors in both new and existing homes. Spray foam insulation’s flexibility makes it the ideal choice for hard to access cavities like walls with irregular shapes or oddly placed electrical outlets. Finally, rigid foam board insulation is an extremely durable option that comes in sheets that fit together easily. As a result, foam board is popular for insulating basements and other areas with larger flat spaces.

Insulating an attic can save you money on heating and cooling

Not only does insulation make it easier to regulate the indoor temperature of your home, but it can also reduce your energy bills. Depending on your climate, insulating an attic could save you around 10% on heating costs, and up to 20% on cooling costs in hotter climates. That can add up to an average savings of about $50 a year! It may not sound like much, but those savings will add up over time. So if you’re looking for small but meaningful ways to save money and energy, insulating an attic is definitely worth considering.


In 2023, insulating an attic is a smart investment for homeowners. Not only will it help to save money on energy bills in the long run but there are also grants and incentives available that can further reduce costs. It can cost anywhere from a few hundred dollars to several thousand dollars depending on a few key factors. Insulation could potentially save up to 20% on cooling costs in hotter climates so if you’re looking for ways to lower your energy bills this year – consider investing in some quality attic insulation!
