Comparing Soundproofing Materials: Foam, Fibreglass, and Beyond


Soundproofing has become less of a luxury and more of a necessity in the hustle and bustle of city life. Whether creating a home theatre, office space, or a serene sanctuary, choosing the right soundproofing material can make all the difference. While professional soundproofing contractors in Singapore are the best people to consult when determining the ideal soundproofing measures for your needs, there’s no harm in learning about the soundproofing materials used. Thus, this article will explore the features, pros, and cons of various soundproofing materials, such as foam and fibreglass.

Acoustic Foam

Acoustic foam panels are designed to absorb sound waves, thus reducing echoing and background noise.


When it comes to affordability, foam frequently emerges as a frontrunner. It is generally less expensive than other soundproofing materials, making it an ideal choice for those within a budget. Foam is also incredibly easy to install: you can attach foam panels to your walls, ceilings, or floors using simple adhesive strips or glue.


Despite its versatile applications, acoustic foam does have its limitations. While it’s excellent for absorbing sound, it’s less effective at blocking sound from entering or exiting a space. Aesthetically speaking, foam panels may not align with every design scheme, limiting their applicability in some settings.


Fibreglass panels are made from fine glass fibres and are highly effective in trapping sound waves.


Unlike foam, fibreglass excels at not just absorbing but also blocking sound. This makes it a more comprehensive solution for spaces requiring stringent soundproofing measures. Another advantage of fibreglass is its fire-resistant properties, making it a safer option in most environments. It also tends to have a longer lifespan, thus maintaining its soundproofing effectiveness over extended periods.


However, these advantages come at a cost—fibreglass is generally more expensive than foam. Additionally, its installation typically demands professional expertise, adding to the overall expenditure.

Beyond: Other Materials

Mass Loaded Vinyl (MLV)

ass Loaded Vinyl (MLV) is a flexible material known for its excellent sound-blocking capabilities, often finding applications in industrial settings. However, it comes with a high price tag.

Acoustic Panels

Composed of compressed mineral wool or foam, these panels are highly effective for sound absorption and are often used in professional settings like recording studios.

Acoustic Plasterboard

This denser version of regular plasterboard provides a more effective sound barrier for walls and ceilings.

Green Glue

A viscoelastic compound that converts sound energy into heat, Green Glue is usually applied between two layers of drywall or plywood to improve sound isolation.


In summary, while foam offers an affordable and easily installed solution, its capabilities are limited. Although expensive and more complex to install, fibreglass offers a comprehensive and effective soundproofing solution. Other materials like MLV, acoustic panels, and Green Glue offer specialised options to meet distinct requirements.

Therefore, before you decide on a material, it’s imperative to understand the specific soundproofing needs of your space clearly—be it sound absorption, sound blocking, or both. In cases of uncertainty, professional consultation can offer valuable insights to make your soundproofing project effective and safe.
