After evaluating your current attic insulation, it is important to determine the type of insulation you need. One of the first decisions you will need to make is whether to use blown in or batt insulation. Blown in insulation is a popular choice for attics because it can be quickly and easily installed, and it can fill in small gaps and crevices that may be present in your attic space. Batt insulation is another option that comes in pre-cut panels or rolls that must be laid out manually.

When deciding between blown in and batt insulation, there are a few factors to consider. First, blown in insulation tends to have a higher R-value per inch than batt insulation, which means that it provides better thermal resistance. This can help keep your home warmer during cold winter months and cooler during hot summer months. However, batt insulation may be easier to install if you have an irregularly shaped attic space or if you have obstructions like pipes or ductwork that may interfere with the installation process.

Another consideration when choosing the type of insulation for your attic is the R-value. The R-value measures how well the insulation resists heat flow and is determined by factors such as thickness, density, and material type. The higher the R-value, the more effective the insulation will be at reducing energy loss and improving comfort levels in your home. Your climate zone will also play a role in determining what R-value you need for your attic.
