Insulation not only keeps your home warm in winter but also cool in summer. There are several options available, including fiberglass, foam board, spray foam, and cellulose. Each has its pros and cons, depending on your specific needs and wall structure.Types of Insulation for Exterior Walls1. Fiberglass Insulation: This is one of the most common types of insulation. It comes in batts or rolls and is relatively inexpensive. Fiberglass is non-combustible and offers a good R-value, but it can be less effective if it becomes wet.2. Foam Board Insulation: Made from rigid foam panels, this type of insulation provides a high insulating value for relatively little thickness. It's often used in new construction and can be cut to fit around studs and other obstacles.3. Spray Foam Insulation: This insulation expands on application and fills gaps and cracks, offering superior air sealing. While it’s more expensive, it provides excellent thermal resistance and can reduce energy bills significantly.4. Cellulose Insulation: Made from recycled paper products, cellulose is eco-friendly and can be blown into walls. It provides good thermal performance but is more prone to settling over time, potentially reducing its effectiveness.Factors to Consider When Choosing InsulationWhen deciding on insulation for your exterior walls, consider factors like climate, cost, R-value requirements, and ease of installation. Also, think about whether you prefer a DIY approach or hiring a professional.ConclusionChoosing the right insulation for your exterior walls can make a significant difference in your home's energy efficiency and comfort.
