Fiberglass insulation is a type of thermal insulation made from fine glass fibers. It is commonly used in buildings to reduce heat transfer, helping to keep homes warm in winter and cool in summer. This material is lightweight, non-combustible, and resistant to moisture, making it a popular choice for attics, walls, and floors. The installation of fiberglass insulation can be done in batts, rolls, or loose-fill forms. It is important to wear protective gear, such as gloves and masks, during installation to avoid skin irritation and inhalation of fibers. Proper installation ensures maximum energy efficiency and comfort in living spaces.
