Types of Insulation Materials for Attics
Choosing the right insulation material is crucial for effectiveness. Each type of insulation has its pros and cons, which can affect your energy savings and comfort levels.
Fiberglass: Affordable and widely used, fiberglass batts are easy to install but can irritate skin and lungs. Cellulose: Made from recycled paper, cellulose is eco-friendly and offers good thermal performance but may settle over time. Foam Board: Rigid and effective at reducing heat transfer, foam board is excellent for unvented attics but can be more expensive. Spray Foam: Provides an airtight seal and high R-value, but requires professional installation and is the most costly option. For related context, read how to install metal roofing panels.
