Types of Attic Insulation

Having a well-insulated attic is crucial for a comfortable home. Proper insulation helps to keep heat in during winter and cool air out in summer, reducing the workload of your HVAC system and lowering energy bills. Insulation also enhances comfort, prevents pests from entering your house and protects against moisture damage.

There are many types of attic insulation, each with its own advantages and disadvantages. The most common type of attic insulation is called blanket or batt insulation, which consists of sheets or rolls of fiberglass, mineral wool, cotton, or other materials. They’re typically cut to fit between joists in the attic. These blankets are fitted to slow the transfer of heat, and are most suited to a standard attic space that’s free from obstructions.

The Environmental Impact of Proper Attic Insulation

Blown or sprayed loose-fill insulation is another option for attic insulation, often made of fiberglass, cellulose, and rock wool. It is blown or sprayed in place using special machinery, and is suitable for attics with a wide variety of obstructions or hard-to-reach spots. This type of insulation offers a quick and efficient installation, and is one of the most cost-effective options for attic insulation.

It is important to ensure that your attic insulation meets the recommended R-value for your location and climate zone, in order to achieve optimal energy efficiency and comfort. If your attic is under-insulated, it’s worth getting in touch with an insulation expert to see how you can improve it.
