What type of insulation is known for friction fitting in space?

Fiberglass batt insulation is recognized for its versatility and effectiveness in various applications, particularly in residential and commercial construction. It is composed of fine glass fibers that are formed into batts or blankets, making it ideal for friction fitting between wall studs, joists, and beams. This friction fit provides a snug installation, minimizing gaps that could lead to thermal bridging and reducing energy efficiency.

The characteristics of fiberglass batt insulation allow it to maintain its structural integrity while also being lightweight and easy to handle. This makes it suitable for various environments, including areas that require thermal protection and sound dampening. Additionally, fiberglass insulation has good fire-resistant properties, contributing to safety in building applications.

While blanket insulation refers to any insulation product sold in a roll or blanket form, fiberglass batt insulation specifically highlights the use of fiberglass as a material, which is what makes it particularly suitable for friction fitting. Other options, like foil-backed insulation, serve different purposes, primarily addressing vapor barriers or reflective properties, and cellulose insulation is more about eco-friendly applications and air sealing. Thus, fiberglass batt insulation stands out for its unique fitting capability in spaces where precision and snugness are essential.
