"How To Find How Much Isolation You Need"Īll the best! Please don't take offence. I have a few documents on my resources page that clear this up. Some designers have used it in recording studios, but it is always suspended limp between partitions and/or IS the partition. But this entails some very critical details and applications. We have used it to sound-proof RVs and mobile recording rigs. If you constrain it in any way, it becomes a very expensive small mass and ridiculously expensive compared to drywall or any other cheap mass. I'll just make this statement and you can look up the data: MLV MUST be used LIMP. Perhaps you didn't know that and are ignorant of the facts. TempleI hate to call you out on this, but your statements about MLV are completely misleading and false. Recording Studio Designer, Builder, Remodel, Los Angeles Soundproofing, Home Studios Consultant, Acoustic Products for MLV and Quiet Glue Pro Both have helped me out and provide expertise, materials and pro support. Soundproofing San Francisco | Soundproofing | West Coast Sound Solutionsįor MLV and Green Glue. you will get much better results, but it takes a lot of additional materials and is not cheap in terms of cost or labor. If you build out your wall with drywall, MLV, decoupling, insulation, drywall, Green Glue, drywall, etc. If you just glue MLV to drywall and drywall over that, it wont have much effect. Please don’t hesitate to contact us and let us advise you.No advantage per say, as an individual component, but used in combination with other techniques and materials it will have a substantial cumulative effect on sound transmission loss. Our acoustical engineers are happy to consult you as each noise issue is unique. If one would make it thicker the mass will be greater but the flexibility of the material will disappear and noise reduction will not be optimal.ģ mm or 1/8 inch thickness is the optimum thickness. If you make it thinner (necessary for some applications) the noise reduction will be less as the mass will be less. BlastBlock hanging will give it the freedom to move and absorb most of the sound energy.the noise will have to pass through all materials to get through a wall, the more changes in material, the more sound will lose it’s energy, hence wall – air – BlastBlock- air – wall will give the best results.The best way to install BlastBlock is to fit it with nails to a wall on the top and then let it hang loosely in the available space between 2 layers. Sticking it tight to a wall construction will only have a limited noise reduction improvement. For optimized improvement of the noise reduction, this is not the right way. ![]() Some manufacturers sell MLV with one-sided adhesive. The transmission loss (ASTM E90) is 29 Decibel for the 3 mm version (1/8″inch) with a weight of 4.9 kg per square meter. Most companies just buy a MLV, give it a special name and use it for noise reduction, those standard MLV’s are far less effective and most of the times contain Barium.īlastBlock has one of the highest Mold Resistance Ratings.īlastBlock has very good heat and fire resistance and tensile strength. We are manufacturing our own MLV so it’s specially designed for noise reduction. It is a proprietary mall loaded vinyl-based compound with added aluminium. BlastBlock MLV is a fully recyclable product without any Barium, so, it’s a safe and healthy material. MLV is manufactured by a limited number of factories. ![]() This property ( known as hysteresis or damping) contributes to the ability of MLV to attenuate sound. This process, induced by noise, uses a lot of energy hence the noise energy is absorbed and transformed into heat (almost not noticeable). Viscoelastic materials with added rigid properties have 2 main active noise dampening properties, they are soft and will permanently change shape during noise impact however the mlv’s rigid part will make sure that the BlastBlock will return to its original shape. ![]() The inert material that is added is calcium carbonate or barium sulfate. It is a viscoelastic material like polyvinylchloride (PVC /vinyl) that is loaded with a stiff material, this is what gives it it’s strong noise dampening properties. ![]() MLV is the abbreviation for Mass Loaded Vinyl and it has been used for soundproofing for over 50 years. MLV is a much-discussed material and BlastBlock has created it’s optimized version engineered in the Netherlands with added aluminium.
