Summary

When comparing glass wool vs. rockwool acoustic insulation, rockwool typically provides better sound dampening due to its density and structural properties. However, glass wool is lighter and may be more cost-effective depending on the application.

Understanding Glass Wool and Rockwool

Glass wool is made from recycled glass and sand, creating lightweight fibers that provide thermal and acoustic insulation. Rockwool, on the other hand, is crafted from natural basalt rock, resulting in a denser product known for enhanced sound absorption qualities.

Noise Reduction Statistics

According to the National Institute of Building Sciences, sound can travel more easily through lighter materials. Research indicates that rockwool can reduce sound transmission by up to 50%, while glass wool typically provides a 30-40% reduction.

Case Study: Residential Application

A family in a suburban area chose rockwool insulation for a home renovation project, aimed at reducing noise from a nearby highway. Post-installation measurement showed a significant reduction in outside noise by 45%, validating the choice of rockwool for this application.

Case Study: Commercial Use

In an office environment, a tech startup opted for glass wool due to budget constraints. Although it provided cost savings, employees reported distractions from excessive noise levels. Upgrading to rockwool insulation soon after led to a more productive atmosphere, confirming rockwool's superior performance.
