How long is the lifespan of sound insulation materials? Do they require regular maintenance?

Soundproofing materials play a vital role in the pursuit of a quiet and comfortable living and working environment. However, when choosing soundproofing materials, many people, in addition to focusing on their soundproofing effect, are also very concerned about two key questions: How long is the lifespan of the soundproofing material? And does it require regular maintenance? These questions directly relate to our usage costs and long-term soundproofing experience.

Different types of sound insulation materials have significantly different lifespans. Common fiberglass sound insulation cotton typically lasts about 5-10 years. However, if exposed to humid or high-temperature environments for extended periods, the fiberglass may hydrolyze or deform, leading to a decrease in sound insulation performance and a correspondingly shorter lifespan. Furthermore, if fiberglass sound insulation cotton is subjected to external impacts during installation or use, damage to the fiber structure will also affect its normal use.

Rock wool sound insulation typically has a lifespan of 8-12 years. Its advantages include good fire resistance, but its chemical stability is challenged in acidic or alkaline environments, potentially leading to accelerated aging. Furthermore, rock wool is relatively hard, and prolonged vibration or friction can damage its surface, affecting its sound insulation performance.

Due to its material properties, foam sound insulation materials have a relatively short lifespan, approximately 3-8 years. They are susceptible to temperature changes and ultraviolet radiation, leading to aging and brittleness, which reduces their sound insulation performance. Furthermore, their low strength means they can be damaged by accidental squeezing or impact during daily use.

So, do sound insulation materials need regular maintenance? The answer is yes. Most sound insulation materials require some maintenance during use to ensure their performance remains stable. For example, regularly check the sound insulation material for damage or detachment, and repair or replace any damaged parts promptly. For sound insulation materials that easily attract dust, regular dust cleaning is also necessary to avoid affecting their sound absorption effect.
