Fiberglass insulation is widely used in residential buildings due to its effective thermal resistance and ease of installation. It consists of tiny glass fibers, which are arranged in a way that traps air and reduces heat transfer, thereby keeping homes warmer in the winter and cooler in the summer. This type of insulation is praised for its fire-resistant properties and moisture repellency, contributing to energy efficiency and comfort.

In residential settings, fiberglass insulation is commonly available in batts or rolls, making it versatile for various spaces within a home, such as attics, walls, and floors. Its popularity stems from a combination of cost-effectiveness, availability, and significant performance benefits.

While foam insulation, plywood insulation, and cellulose insulation have their own beneficial characteristics and applications, fiberglass insulation stands out as the most commonly used material in residential construction for its performance and practicality.
