Key Takeaways

Fiberglass insulation is a commonly used option that reduces heat transfer and improves energy efficiency, but proper safety precautions must be taken during installation.
Cellulose insulation, made from recycled paper products, offers excellent thermal resistance, soundproofing capabilities, and helps regulate indoor humidity levels.
Spray foam insulation, while more expensive and requiring professional installation, provides excellent air sealing, improves indoor air quality, and has a long lifespan.
Mineral wool insulation offers excellent thermal and acoustic properties, soundproofing capabilities, and is non-combustible and resistant to moisture.

Fiberglass Insulation

Fiberglass insulation is a widely used and highly effective thermal insulation material. It is made from small glass fibers that are tightly woven together to form a dense and flexible material. Fiberglass insulation is commonly used in residential and commercial buildings to reduce heat transfer and improve energy efficiency.

When it comes to installation techniques, fiberglass insulation can be installed using various methods such as batts, blown-in, or loose-fill. Batts are pre-cut sections of insulation that can be easily placed between wall studs or ceiling joists. Blown-in insulation involves using a machine to blow loose fibers into cavities or attics.

However, it is important to consider potential health concerns associated with fiberglass insulation. The tiny glass fibers can irritate the skin, eyes, and lungs if proper safety precautions are not taken during installation. It is recommended to wear protective clothing, gloves, goggles, and a respirator to minimize exposure to these fibers.
