    PRODUCT DESCRIPTION

    Tecsound T35, T50 and TS50 are a polymer-based, asphalt-free, high density synthetic soundproofing membrane, that offers good acoustic insulation in different building elements. It has extremely high visco-elasticity as well as being extremely flexible even in cold temperatures.
    • Available in scrim reinforced (T35 Part Code A116)
    • Available in scrim reinforced (T50 Part Code A120)
    • Peel of self-adhesive backed (TS50 Part Code A130)
    PROPERTIES
    • RW 25.2dB for a single layer (@5kg/m²) (test certificate 4.042.669) and around 32dB for a 10kg/m² double layer.
    • High acoustic insulation especially when combined with lightweight panels and boards.
    • Acoustically equivalent to lead of the same surface weight.
    • Tecsound is particularly effective at reducing the critical dip (or coincidence) frequency which is always present in standard plasterboard constructions as well as increasing the low frequency performance.
    • Improved low frequency performance.
    • Highly flexible.
    • Class0 fire rating. (test certificate 4026067)
    • Airbus Industry (ATS-1,000 . 001) APPROVED
    • Great elongation capacity.
    • Easy handling and adaptable to uneven surfaces.
    • Cold and heat resistant.
    • Excellent ageing resistance.
    • Rotproof.
    This material has excellent sound insulating properties. Many construction materials and techniques do not provide enough damping. Rigid sheet materials such as plasterboard absorb little sound energy becuase they tend to vibrate and re-radiate sound on the other side quite effectively. Tecsound acoustic membrane however has tremendous density and mass whilst being extremely 'limp', its acoustically better than lead of the same surface mass, so will help absorb sound energy far more efficiently.

    Whilst some systems rely on visco-elastic glues to provide 'damping' the results achieved will vary greatly on the application of the glue. Is it too thick ? is it too thin ? has it been applied evenly and consistantly ?

    Visco-elastic glues do not add any extra mass to a system and at the end of the day the best way to reduce bass transmission is by having a heavy weight, heavily damped, mass/spring system. Tecsound Acoustic Membrane provides the best of both worlds, high additional mass and high damping, that can be applied not only over 100% of the area in question but uniformly.

    Fire Performance
    Euroclass B, s2, d0 in accordance with UNE-EN 13823:2002 and UNE-EN-ISO 11925-2:2002. (which is considered to be better than the old British Standard Class 0 rating)
    • B - Contribution to combustion is very limited. Demonstrated that the fire is not propagated beyond the strict area in which it has been applied.
    • s2 - Average amount and speed of emission of smoke.
    • d0 - No flammable drops or particles are produced.
    This classification places the T range at the forefront of soundproofing membranes in terms of fire resistance. It is the first soundproofing membrane on the market to receive Euroclass Certification . To give you an idea of how good this is, Euroclass Standards above B (A1 and A2) can only be awarded to incombustible materials. Materials between Euroclass A and B can be considered the safest in case of fire, whilst those of level C and below can begin to be considered dangerous.
    Worthy of note is that the tests were carried out directly on the product with no incombustible protection such as laminated plasterboard or metal plate and, on the self adhesive version, which makes the result all the more significant!

    APPLICATIONS:
    • Soundproofing against airborne noise in vertical walls with low surface density (lightweight partition walls or boards made of different materials).
    • Soundproofing against airborne noise in ceilings and floors.
    • When bonded between stiff rigid sheet materials it greatly reduces the resonance and coincidence dips.
    • When stapled over frameworks it greatly improves a lightweight partitions overall performance.
    • When bonded to lightweight resonating metal panelwork it greatly reduces vibration and re-radiated noise.
    • Damping of impact noise caused by rain on metal deck roofs.
    • Combined with sound-absorbent materials, it offers products with high acoustic performance.
    • Its applications in the industrial field cover from the soundproofing of booths to the acoustic insulation of machine-rooms, gutter pipes, sound-damping of metal sheets, etc.
