Sound insulation material SGM Barrier Mix Prime
SGM Barrier Mix is a top membrane material of the latest generation from the top model line SGM Prime from 2020. With a thickness of only 6 mm, it enables sound insulation of up to 35 dB, which, together with Barrier Mix Profi, currently ensures the world's first place among anti-noise materials. The efficiency of SGM Barrier Mix was achieved thanks to the principle of absorption of resonant sound, which has not been used in the field of automotive sound insulation. A specially selected material composition with precisely calculated characteristics of the base layers also plays an essential role. Barrier Mix is composed of a 4 mm thick sound insulation layer and a 2 mm thick anti-noise membrane. Thanks to this, it fully replaces the second and third layers of soundproofing, thus saving installation time and, of course, its price. SGM membrane materials also perform a thermal insulation function thanks to their multi-layer structure with an acoustic membrane. Barrier Mix contains a waterproof upper layer with an anti-noise membrane, however, the soundproofing layer is not 100% waterproof and therefore we recommend this material mainly for the interior of the car. The extremely adhesive self-adhesive layer guarantees efficiency from -40 °C to +100 °C and the material maintains constant efficiency throughout the life of the vehicle.
The main properties of the SGM Barrier Mix material
- Premium sound and heat insulating material from the top line of SGM Prime.
- The most effective anti-noise material on the market today with a thickness of 6 mm.
- The currently unsurpassed sound insulation capability of up to -35 dB.
- It fully replaces the second and third layers of soundproofing with maximum efficiency.

Where to apply the SGM Barrier Mix material
Barrier Mix Prime is intended primarily for soundproofing the most noise-burdened areas, which are mainly the floor, the central tunnel, the rear skirts on the side of the trunk or the partition of the engine compartment. It is applied as a second layer to an anti-vibration material that prevents vibrations and noise at the lowest frequencies (e.g. SGM Dual Prime or SGM Onyx 3 ). Thanks to the multi-layer composition with a noise-reducing membrane and a thickness of only 6 mm, it is no longer necessary to apply a third layer of noise reduction, which is fully replaced by Barrier Mix, due to the extreme efficiency of the material (up to 35 dB). Avoid application near highly heated areas such as the engine and exhaust system. The most common uses of SGM Barrier Mix Prime sound insulation material:- Floor
- Rear wheel arches from the side of the trunk
- Engine compartment bulkhead
- Central tunnel
- The bottom of the luggage compartment
- Space under the rear seats
- Fenders
About SGM damping materials
The Russian company SGM Technology was founded in 2006, and since then it has been one of the leading Russian manufacturers of sound and heat insulation materials for the automotive, shipbuilding, aviation and construction industries. The combination of excellent physical properties of materials and technological methods is the result of the highly efficient performance of the specialized workforce of SGM, which consists of specialists from the best technical universities of Russia. Currently, SGM offers over 200 types of materials that meet the strictest quality and stability standards with certification according to ISO 9001: 2008 and ISO / TS 16949. Long-term cooperation with such giants as Bosch or LG is proof of the highest quality of SGM products, which has long been one of the best on the market today. At the turn of 2019 and 2020, the SGM company presented hi-tech noise-reducing materials from the top Prime series, which in their performance slightly surpass even the premium materials of the market leader in noise reduction from Comfortmat. You can buy the products of both highly competitive manufacturers, who are constantly competing with innovations in the field of vehicle sound deadening, on our e-shop with a guarantee of the most technologically advanced and most effective products of today. Thanks to the official representation of our company for the Czech Republic and Slovakia, you can count on sufficient stock and professional service..jpg)

| Acoustic Loss Factor (MLF)The acoustic loss factor (in English, mechanical loss factor) expresses the ability of the material to absorb propagating sound and change the energy of vibrations created by the sound into thermal energy. The theoretical maximum loss factor is 1, which means no vibration. For example, non-sound-proof steel with a thickness of 1 mm has a loss factor of approx. 0.001 at 200 Hz. Therefore, the higher the loss factor, the better. By combining damping materials, it is possible to significantly increase the loss factor to values approaching 1. | 0.12 |
