In the ever-evolving realm of architectural innovations, Onduline® emerges as a pioneer not only in waterproofing but also in sound absorption technology. Architects, engineers, and contractors, brace yourselves for a revolutionary roofing solution that transforms your spaces into havens of tranquility.
Understanding Sound: A Symphony of Vibrations
Before we delve into the auditory prowess of Onduline® sheets, let's unravel the science behind sound. In physics, sound is the energy that traverses through matter in the form of waves. These mechanical waves, comprising variations in pressure, density, and particle displacement, propagate through a medium—be it air, water, or other materials.
Now, imagine the harmony of guitar strings or the rhythmic patter of raindrops on an Onduline® sheet. These stimuli induce vibrations that set neighboring particles into motion, creating a chain reaction. Just as guitar strings use nylon, Onduline® employs bitumen—a viscoelastic material—for its roofing sheets.
Bitumen: The Noise Blocker
Bitumen, renowned for its waterproofing prowess, reveals an additional talent—remarkable sound absorption. As a viscoelastic material, bitumen has the unique ability to absorb sound by converting vibrations into heat. This property makes it a key player in reducing the transmission of vibrations caused by external sources.
The significance of bitumen in sound absorption extends beyond roofing; it's a heavyweight champion in automotive engineering and household appliances, where it acts as a soundproofing material. The viscoelastic nature of bitumen, blending viscosity and elasticity, allows it to dissipate mechanical energy efficiently, attenuating vibrations and absorbing sound energy.
Impact Noise: Rain, Wind, and Debris
Onduline® sheets excel in absorbing impact noises—whether it's the rhythmic drumming of raindrops, the whisper of wind, or the clatter of fallen debris such as leaves and branches. This feature is especially crucial in countries where insulation is limited, and roofing materials are visible from the inside.
Quantifying the Silence: A 23 dB Difference
To put Onduline®'s sound-absorbing prowess into perspective, consider this: Onduline® CLASSIC sheets generate 23 decibels less noise under rainfall compared to a 3mm-thick metal roofing sheet with a ribbed profile. In practical terms, this means the indoor environment with Onduline® is four times quieter than under a metal roof.
The reduction from 83 dB(A) to less than 60 dB(A) is life-changing, creating a peaceful haven even during heavy rain. This noise reduction has been rigorously tested and validated by the Indonesian National Laboratory for Aerodynamics, Aeroplastics, and Aeroacoustics technology, following ISO 140-18:2006 standards.
Onduline® in Stables: Where Horses Feel Safe
Beyond architectural realms, Onduline® has become the preferred roofing system for stables. Horses, sensitive to noise during storms, find solace under Onduline® roofs. Unlike traditional materials that let sounds pass through, Onduline® sheets absorb and dampen the impact, creating a safer and quieter environment for our equine companions.
In conclusion, Onduline® doesn't just protect against the elements; it orchestrates a symphony of silence. Architects, engineers, and contractors, choose Onduline® for a roofing solution that not only enhances architectural aesthetics but also transforms spaces into peaceful retreats. Experience the Onduline® advantage—the perfect blend of form, function, and serenity.
