Acoustic coatings are very thin layers of material that absorb sound, but they can be sprayed over other sound-absorbing structures to increase their effectiveness across a wider frequency range.
Additionally, for the course of its operational life, this biofiber-based coating functions as a carbon sink, lowering the building’s overall carbon footprint. As a result, the coating is environmentally friendly and sustainable.
Three case studies, all of which had stringent criteria to hide the acoustic structures, are used in the present work to illustrate the absorption characteristics of the biofiber-based coating.
In many cases, the blueprints include the acoustic design at the price of the architectural ambition. Traditional acoustic structures consist of glued sound-absorbing panels or suspended ceiling systems, which may not be the most appealing option visually.
In buildings that are historically significant or otherwise architecturally protected, using panels or suspended structures is frequently impossible.
Acoustic coatings provide a way to increase acoustic comfort while preserving the aesthetic appeal of surfaces and can even make it impossible to identify them as sound-absorbing materials from a distance.
This acoustic coating is effective at absorbing sound but not at blocking it. No matter how thick it is, a mere coating will never be able to completely block sound. You cannot soundproof a wall unless you add substantial bulk, such as an additional layer of plasterboard or a soundproofing membrane.
Similar to soundproofing panels, noise-reducing materials (NRC-rated materials) will aid in sound absorption.
Many of these “soundproof” paint manufacturers blend what they refer to as thermacels with the paint’s pigments. Thermacels behave like the shocks on a bicycle when sound strikes them by absorbing the impact and lessening echo.
Even after learning all this information, it’s clear that soundproof paint isn’t the best available solution for sound absorption.
The global soundproof coatings market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Providing vibration dampening and lowering vehicle noise, Audioguard is a waterborne, spray-applied coating from PPG Commercial Coatings.
Commercial OEM body builders can use Audioguard, winner of the PACE Award for Supplier Product and Process Innovation, as a solution to reduce structural vibration and noise in cabins, beneath hoods, within wheel wells, and on interior panels.
Because it is waterborne and has zero volatile organic compounds (VOCs), Audioguard is a particularly environmentally responsible approach to handle vehicle noise and vibration issues. It is constructed of a patented blend of fluid, fibre, and resin that cures into a strong coating material.
ArmaGel HTL, a novel, non-combustible aerogel blanket especially built for industrial applications where non-combustibility, thermal performance, and corrosion under insulation mitigation are vital, was just launched by Armacell, a global pioneer in energy efficiency.
The newest development from Armacell keeps mechanical equipment dry for longer and improves protection against corrosion underneath insulation by repelling water while allowing vapour to escape. Additionally, the availability of 5, 10, and 20 mm thicknesses offers consumers more options and facilitates a quicker installation.
Furthermore, ArmaGel HTL is among the easiest, quickest, and most affordable ways to increase energy efficiency. This aerogel blanket’s outstanding thermal performance enables a successful worldwide reaction to climate change.
