Hey everyone, let’s talk about something I get asked CONSTANTLY as a PET flooring supplier: what’s the actual acoustic performance of this stuff? A lot of folks roll their eyes when they hear “sustainable flooring” — they think, “Yeah, it’s eco-friendly, but will it actually do anything for my space when it comes to noise?” I’ve been in the game for years, working with every type of client: small café owners renovating their tight downtown spots, office managers fighting open-plan chaos, even a few residential folks who hate hearing their upstairs neighbor’s TV at 2 a.m. So let’s break this down like I would chat over a coffee — no jargon, just real stuff you can actually use. PET Flooring
First, let’s cut to the basics: what even is PET flooring for those who don’t know (though I’m guessing if you’re here, you’re probably deep in the hunt). It’s made from 100% post-consumer recycled plastic bottles — think the ones you toss in the bin for curbside pickup, right? We collect those, shred ’em, turn ’em into fibers, then press ’em tightly to create those interlocking tiles or planks people install. But back to acoustics, because that’s the big one. When people ask me about noise, they’re usually thinking two main things: impact noise (that thud of heels, a dog running, a glass being dropped) and airborne noise (conversations, music, a TV blaring next door). PET flooring hits both way harder than a lot of people expect.
Let’s start with impact noise, because that’s the one that makes or breaks multi-level spaces. I’ll use a recent example: a small yoga studio I worked with in Brooklyn last year. They had an upper level where classes ran, and a ground-floor coffee shop that got busy on weekends. The owner was freaking out because every time someone stomped during a tree pose, the baristas below could hear it so clear they’d pause their orders. Old flooring was the standard medium-density fiberboard (MDF) vinyl plank garbage — it basically acted like a drum, bouncing every thud straight through. We installed our PET acoustic tiles, and three weeks later the owner hit me up laughing, said a regular who works at the coffee shop brought her a free latte “for the first time in months.” Why? PET’s core is super dense but also has that soft, fibrous structure — it’s not hard like wood or vinyl, so it absorbs that impact instead of reflecting it. The lab tests we do in-house (I show clients these, no shady numbers) say it reduces impact noise by like 15 to 20 decibels. Wait, what does that even mean? If your upstairs kid’s toy box being dropped from a foot high was a 60-decibel noise (like a normal conversation), that drops to 40 — which is basically library-level quiet. Compare that to vinyl, which only knocks off 5 or 6 decibels, and you see the difference.
But here’s the thing I hate when other suppliers gloss over: it’s not just the flooring itself, it’s what it’s installed over. A lot of people think just putting PET tiles on subfloor is enough, but skip the underlay? That’s half the battle missed. Wait, let’s clarify: some PET products come with a built-in acoustic underlay, but even if yours doesn’t, pairing it with a closed-cell foam underlay (the thin, flexible kind, not that crumbly open-cell stuff) boosts impact noise reduction by another 10 decibels, easy. I had a residential client last month who lived in a 3-story walkup — her previous floor was hardwood on plywood, and she could hear her downstairs neighbor’s alarm go off every morning. We did the PET tiles with the built-in underlay, and now she only hears it if she puts her ear right to the ceiling. That’s a real win.
Now airborne noise, which is the forgotten one for a lot of folks. Airborne noise is when sound travels through the air — so open-plan offices where someone takes a call and the whole team hears it, or apartment walls where the neighbor’s TV is a constant background hum. A lot of sustainable flooring gets written off here, but PET is actually pretty solid. The dense fiber structure of PET blocks sound waves instead of letting them pass through, unlike wood or luxury vinyl plank (LVP) which are porous (even if you can’t see it) and let sound seep through. For open-plan office clients, this is their main pain point. I worked with a tech startup that had 20 people in a 1,000-square-foot space — before, they used LVP, and every call was a group huddle. After we installed our PET planks, they reported a 30% drop in background noise, and people said they could focus way better. I’ve seen in test reports that PET flooring has an airborne noise transmission class (NRC) of 0.45, which is higher than LVP’s 0.25. NRC is the rating that measures how much sound a material absorbs — 1 is perfect, 0 is nothing. So 0.45 means it’s absorbing nearly half the sound that hits it, instead of bouncing it around your room like LVP does. That’s why office open areas don’t turn into echo chambers, why café noise doesn’t travel all the way to the back corner, why your kid’s playroom noise doesn’t bug the living room.
Wait, but let’s be real — no product is perfect, right? I don’t sugarcoat that. PET flooring isn’t the best for every acoustic scenario. If you’re in a space with super high impact noise, like a gym with heavy equipment or a warehouse where pallets get dropped, you might need an extra thick underlay to make it work — but even then, it’s still better than most alternatives. And for airborne noise through walls? No flooring will fix that, that’s the insulation and drywall. But for within the room and between floors, it’s top-tier.
I also get a lot of questions about how it compares to other eco-friendly options, like cork or bamboo. Let’s do a quick real-world test from my side, not just lab numbers. Cork is soft, right? It absorbs impact, but it’s way thinner, and it compresses over time — so after a year or two, that impact noise reduction drops off. Bamboo is hard, almost like wood, so it bounces sound instead of absorbing it, so acoustic performance is garbage. PET? It stays dense and flexible for years — we’ve had client floors in commercial spaces for 5 years now, and their acoustic ratings still match when we first installed them. That’s a big deal for businesses that don’t want to re-do flooring every 2 years because the noise got worse.
Another thing people don’t talk about: it’s not just about reducing noise, it’s about making the space feel calmer. I’ve had clients say that even if the noise level is technically the same, the room feels quieter. Why? Because hard surfaces (like tile, wood, LVP) reflect sound, so you get that constant echoey hum that makes your ears feel tired after a while. PET absorbs that echo, so the sound feels more controlled. That’s why offices see higher productivity, cafés have less customer complaints about loud spaces, apartments are way more livable.
Now, let’s cover some common myths I hear a lot. First myth: “PET flooring is thin, so it can’t block noise.” Nah, most commercial PET tiles are 8 to 12 mm thick, with the core made of tightly pressed recycled plastic — that’s way denser than a 6 mm LVP plank, and density is half the battle for sound blocking. Second myth: “It’s only good for impact noise, not airborne.” I’ve already talked about office clients, but residential folks with open floor plans say the same — if you have a kitchen next to a living room, the PET flooring keeps kitchen clatters from bugging people watching TV, way more than wood would. Third myth: “It’s just a fad, so the acoustic performance won’t last.” Again, I’ve got real clients with 5-year-old floors, and the numbers don’t lie. The recycled plastic fibers don’t break down or compress like natural materials, so the acoustic performance stays consistent.
Wait, let’s wrap this up with some practical takeaways, because that’s what you actually care about, right? If you’re a café owner, get the 10 mm PET tiles with built-in acoustic underlay — that’ll stop foot traffic noise from bothering customers at the back. If you’re an office manager in an open space, pair PET planks with a 5 mm closed-cell underlay to cut down that call echo. If you’re a residential client in an apartment, go for the interlocking tiles (super easy to install yourself) with the underlay, and you’ll barely hear your upstairs neighbor’s footfalls.
