Myths and Truths in Acoustic Isolation<\/strong><\/strong><\/h1>\n\n\n\n

We dismantle mistaken beliefs to help you build without errors<\/strong><\/strong><\/h2>\n\n\n\n

When it comes to planning acoustic insulation, many decisions are made under the influence of popular beliefs that have little or nothing to do with technical reality. That\u2019s why we\u2019ve gathered the most common myths and debunk them one by one with technical arguments and real solutions.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n
\u274c Myth<\/strong><\/td>\u2705 Truth<\/strong><\/td><\/tr>
\u201cA single drywall board is enough\u201d<\/td>At least two boards per side are required to ensure both mass and acoustic rigidity.<\/td><\/tr>
\u201cRock wool or mineral wool solves everything\u201d<\/td>Absorbent materials contribute absorption, but they don\u2019t provide isolation on their own. They are only one component of the complete system.<\/td><\/tr>
\u201cAny sealing strip will do\u201d<\/td>Only EPDM acoustic strips, like SENOR SE-BEC, provide airtightness, elasticity, and durability.<\/td><\/tr>
\u201cResilient mounts are optional\u201d
<\/td>		They are essential to break structural contact and prevent vibration transmission.<\/td><\/tr>
\u201cIt\u2019s better to install the floor first\u201d<\/td>The floor should go last so that partitions and linings remain decoupled.<\/td><\/tr>
\u201cIf it looks well installed, it works well\u201d<\/td>A system may look correct but fail in key invisible aspects: airtightness, supports, or modulation.<\/td><\/tr>
\u201cElastic connections make insulation worse\u201d<\/td>Elastic connections provide safety, rigidity, and vibration absorption\u2014they don\u2019t make the system worse.<\/td><\/tr>
\u201cMineral wool works as a resilient mount\u201d<\/td>No. Mineral wool has no elastic recovery capacity. It cannot replace an acoustic mount.<\/td><\/tr>
\u201cWith acoustic panels I won\u2019t hear my neighbor anymore\u201d<\/td>That\u2019s acoustic conditioning, not isolation. It only improves the sound inside the room.<\/td><\/tr>
\u201cEverything sold on the market is valid\u201d<\/td>Many systems are untested. At SENOR, we test all our systems to guarantee their performance.<\/td><\/tr>
\u201cThe cheaper, the better\u201d<\/td>Price shouldn\u2019t be the top priority\u2014the result is. A bad system is always a bad investment.<\/td><\/tr>
\u201cNo need to think about safety\u201d<\/td>Every component must include a safety device. At SENOR, it\u2019s an essential part of the design.<\/td><\/tr>
\u201cIf it isolates sound, it complies with regulations\u201d<\/td>In many cases, fire resistance EI is also required. SENOR offers systems with EI120 and EI180.<\/td><\/tr>
\u201cInstallation order doesn\u2019t matter\u201d<\/td>It does. The sequence affects final insulation. A bad order can cost you decibels.<\/td><\/tr>
\u201cI just need to glue some foam to the ceiling\u201d<\/td>Glued foams don\u2019t isolate vibrations or provide safety. They cannot replace a real acoustic system.<\/td><\/tr>
\u201cThe installer\u2019s experience is enough\u201d<\/td>Experience is valuable, but modern systems require specific and up-to-date technical training.<\/td><\/tr>
\u201cIf I use good products, installation doesn\u2019t matter\u201d<\/td>Installation is key. Poor assembly ruins even the best materials.<\/td><\/tr>
\u201cNo need to seal every joint\u201d<\/td>Air and sound leaks can reduce isolation by up to 16 dB. Airtightness is essential.<\/td><\/tr>
\u201cRigid fixings on channels don\u2019t matter\u201d<\/td>Without mounts around the perimeter, acoustic bridges are created.<\/td><\/tr>
\u201cAny roof support is fine for an acoustic ceiling\u201d<\/td>They must be specific and safe. SENOR\u2019s SE-F-RAPID supports are the only ones with DS (safety device).<\/td><\/tr>
\u201cA technical sheet is just a piece of paper\u201d<\/td>No. It contains key information to ensure product performance.<\/td><\/tr>
\u201cIt\u2019s all just a matter of luck\u201d<\/td>It\u2019s not luck\u2014it\u2019s technical knowledge, proper execution, and tested solutions.<\/td><\/tr>
\u201cAdding mounts is enough\u201d<\/td>You must choose mounts compatible with the profiles and within their load range.<\/td><\/tr>
\u201cYou don\u2019t need that many hangers\u201d<\/td>Using fewer hangers compromises ceiling safety. The risk of collapse is real.<\/td><\/tr>
\u201cAcoustic strips are too expensive and unnecessary\u201d<\/td>They are affordable and essential to guarantee airtightness and avoid sound and thermal bridges.<\/td><\/tr>
\u201cDrywall boards must be left 1 cm above the floor\u201d<\/td>Boards should rest on the acoustic strip. Otherwise, airtightness is lost.<\/td><\/tr>
\u201cStrips should only be as wide as the metal profile\u201d<\/td>They must cover the profile and boards to ensure proper sealing and prevent transmissions.<\/td><\/tr>
\u201cFloors should be built before partitions and\/or linings\u201d<\/td>They must be done last to maintain element decoupling.<\/td><\/tr>
\u201cExterior walls don\u2019t need plastering\u201d<\/td>A plaster layer improves mass, rigidity, and airtightness. It\u2019s fundamental to acoustic performance.<\/td><\/tr>
\u201cIf I replace or remove some products, it doesn\u2019t matter\u201d<\/td>Each component has a purpose. Replacing or removing it can compromise the entire system.<\/td><\/tr>
\u201cNo need to place absorbent material\u201d<\/td>It\u2019s essential in multilayer systems. Without it, acoustic performance drops drastically.<\/td><\/tr>
\u201cResilient mounts are too expensive\u201d<\/td>They offer excellent value: improved performance, safety, and faster installation.<\/td><\/tr>
\u201cSince insulation isn\u2019t visible, it doesn\u2019t matter\u201d<\/td>Even if unseen, it ensures comfort. It\u2019s as essential as electrical or plumbing systems.<\/td><\/tr>
\u201cInsulation is a bad investment\u201d<\/td>It\u2019s a key investment: improves comfort, increases property value, and prevents future costs.<\/td><\/tr>
\u201cIf I use a fire-rated board, it meets the standard\u201d<\/td>A single board isn\u2019t enough. The entire system must be tested and certified.<\/td><\/tr>
\u201cAcoustic insulation is too expensive\u201d<\/td>Properly executed insulation is one of the most profitable investments: it improves comfort, avoids neighbor conflicts, increases property value, and reduces future costs.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
