Product Description

Tecsound® is a high-density, polymer-based asphalt-free synthetic soundproofing membrane, which is visco-elastic and highly adaptable, and provides good acoustic insulation in the different construction elements without increasing thickness. We offer four variants – Tecsound 35, Tecsound 50, Tecsound 70, and Tecsound 100, and Tecsound SY100 (Self Adhesive)

Tecsound was first introduced to the soundproofing industry as a replacement for lead sheeting. Lead sheeting had been the soundproofing agent of choice for several years but, as we all know, lead was later determined to be a toxic agent and the need to find a replacement product became imperative.

Texsa Tecsound® Specifications:

  • Density: 2000 kg/m³ (Twenty Five Times heavier than RockWool, as heavy as lead)
  • Thickness: Tecsound 35 – 1.75mm, Tecsound 50 – 2.5mm, Tecsound 70 – 3.5mm, Tecsound 100 – 5.2mm
  • Pliability: Does not break when bent at -20°C
  • Tensile strength: 30 N/cm²
  • Elongation: 300%
  • Crushing strength: 4.84 kg/cm²

Texsa Tecsound® Advantages:

  • Vibration reduction: an ideal solution to solving vibration problems.
  • Convenient: Easy to install with Fevicol SR, Speb 7, or any high grade spray adhesive.
  • Practical: bitumen-free and totally recyclable

Texsa Tecsound® Applications:

  • Airborne noise insulation in vertical surfaces with low surface mass (lightweight partitions or panels in various materials)
  • Airborne noise insulation in ceilings and roofs
  • Reduction of impact noise level in all types of frameworks, information of floating floors
  • Damping of impact noise produced by atmospheric agents in metals roofs
  • In combination with sound-absorbent materials, it results in products with high acoustic performance characteristics
  • Its applications in the industrial sector range from soundproofing booths to insulation of machine rooms, drainpipes, acoustic damping of metal sheets etc.,

Mass Loaded Vinyl Membrane can be used in various places like Offices, Recording studios, Music rooms, Residential areas, Home theaters, Rehearsal rooms, Nightclubs, Auditoriums, Conference Rooms, Hotels, Dubbing room, Schools & Universities, Generator rooms, Commercial places, etc.

Texsa Tecsound® Features:

  • High acoustic insulation, combined with flexion-pliable elements (sheet plaster, carrier board)
  • Flexible
  • High elongation capacity
  • Easy to handle and adaptable to uneven surfaces
  • Hot and cold-resistant
  • Self-extinguishing
  • Excellent ageing-resistance
  • Rot-proof

Instructions for use

The Tecsound acoustic membrane can be applied to most surfaces including rendering , plasterboard, metal, and most plastics. The surface should be even smooth clean and dry. The surface should be cleared of any elements that might cause damage to the membrane. Old plaster work should be checked and possibly primed first to ensure good adhesion.

When adding to a wall you have a number of choices. With a resilient bar system we recommend that you add it at the 19mm plywood/gypsum/bison board level. Glue regular Tecsound with a high performance adhesive like Fevicol SR or Speb 7. The membrane should be overlapped at junctions and run right up to the walls and ceiling overlapping by around 10mm.

When adding to the floor we ideally recommend adding straight to the floor surface. This can be onto floor boards or to other floor surfaces. However you can also add draped over the joists, if you are looking to have wooden floor boards above. Again at the joins we recommend at least 3cm overlap and run the membrane right up to skirting boards or walls so no gap is left.

Ceiling applications can prove trickier and we would tend to use Tecsound 35 which is lighter and easier to handle. However if you are set on using Tecsound 100 on the ceiling we would again apply it after the the 19mm plywood / gypsum / bison board. This can then be sandwiched between the 19mm and 12.5mm boards.

Some of the many uses for the flexible membrane can be seen below. Its use in anything from car sound proofing to improving speaker performance. It also has use in industrial soundproofing.

  3. Fixed the leak

    Amogh Gadre

    Good performance for damping sound leakage from door of home theatre. Requires additional layer of ply/mdf because it does not look good exposed. Very heavy and should handle with care – two people needed to install. Felt it was expensive but free shipping compensates for the price. Other companies offered lower rate but wanted Rs 3000 to courier one piece! 5/5 for one day delivery to Pune. Seamless transaction.

Our head-office is in Mumbai; however, we don’t have a showroom or physical stores. We're an online company - we distribute our products online all over India via a distributed warehousing system - we have warehouses in 8 locations. Since our products are technical and used for solving specific acoustic problems, they do not attract walk-in customers. If you want to buy our products, just place your order online or reach out to us via the contact forms.
We do not offer Cash on Delivery. Our products are extremely large and bulky - you can fit a human being into most of our boxes. As a result, one of the highest costs in running this company is the money paid to courier companies like Fedex, XPressBees, etc, which runs into crores of rupees annually. If we allowed COD and the buyer changes their mind and refuses to pay during delivery, we incur double shipping costs (a) for sending the product to the buyer + (b) for shipping the product back to our warehouses. In some cases, this may be more than the value of the product itself. For this reason, we find it impossible to offer Cash on Delivery.
We follow maximum transparency in showing you actual delivery dates at a product level. The exact delivery dates are visible on each product page, cart page, checkout page, as well as your order confirmation emails. Once your order is shipped, regular shipping updates are provided via SMS.
We supply products only. We're an ecommerce company and our focus is on importing, distributing, manufacturing, and supplying a wide range of technical isolation & acoustic products across India. For installation you can engage local contractors / carpenters. Please contact us if you need specific information on installing any product in our catalog.
We accept returns upto 30 days from the date of receipt of product. If you need to return a product, just contact your sales representative and we will arrange a reverse pickup via Fedex. Your refund will be processed within 3 days after we get it back. We charge a 15% fee for restocking the product so this is subtracted from your refund. This is waived off if you have not removed a product from it's original packing and are returning it unused.
Your order could be in several spots... our warehouse, our custom-shop manufacturing units, anticipating dispatch, with the courier on its way, or conveyed. The principal thing to check is have you had your dispatch email? If yes, at that point it's en route. You can track your order by clicking your tracking link from that email. In the event that you haven't got your dispatch email within a week of placing your order, please do contact us.
