Tecsound SY100 self-adhesive membrane is a high-performance viscoelastic material that reduces airborne noise and dampens vibrations

Use Tecsound SY100 in various applications, including soundproofing for walls, ceilings, and floors. Tecsound SY100 is a 10kg/m² viscoelastic membrane that adds mass when applied to various structures reducing airborne sounds. Reduce vibrations through plasterboards and other hard surfaces that resonate with sounds with Tecsound. Combine Tecsound with acoustic insulation, soundproof plasterboard and the AcoustiClip to form a complete soundproof system.

SKU: 010060 Categories: Ceiling Soundproofing, Wall Soundproofing


Tecsound SY100 is a highly versatile soundproofing membrane. It is used in various types of construction that require a thin, yet effective barrier to reduce airborne and vibration sounds.

The self-adhesive Tecsound sheets are suitable for most wall and ceiling surfaces. One of the main areas of use for Tecsound is between sheets of plasterboard. The viscoelastic nature and high mass/density of the product ensure vibration and airborne sounds are significantly reduced when applied to the plasterboard. Use Tecsound directly onto metalwork to minimise structural vibration.

Tecsound SY100 Applications

• Increases airborne noise insulation on partition walls with low surface mass (stud walls and party walls)
• Soundproofing against airborne noise in ceilings and lightweight roofs
• Reduction of impact noise in laminated floors
• Damping of noise caused by weather such as rain and hail in lightweight roofs
• Combined with sound-absorbent materials, it offers solutions with high acoustic performances
• Its applications in the industrial field cover from the soundproofing of cabins to the acoustic insulation of machine-rooms, cowling of engines, gutter pipes, sound-damping of metal sheets, etc

Installing Tecsound SY100

  • Tecsound SY is mainly applied between two plasterboard panels
  • The membrane adheres with the self-adhesive underside to the first plasterboard to which the second plasterboard is attached

To prevent thickening, the membrane is placed without overlap (only butt joint). Care must be taken to ensure that the seams fit tightly and that there are no openings
Tecsound SY can also be used in lightweight roofs. Install the membrane with the polyethene film on top and overlap of at least 50 mm. In the case of profiled steel deck, the membrane must be placed transversely to the profile. Make sure that there are no openings as these will have a negative effect on the noise reduction capacity

Make sure you are getting the right soundproofing for your needs. Understanding the most common types of noise and how to stop them will help you decide the right solution.

Different Types of Sound

  • Airborne sounds – Conversation, TV noise and radios are examples of airborne sound. The best way to stop airborne sounds is to add mass/density to the walls or ceilings.
  • Impact/vibration sounds – Footfall and moving furniture across a floor are examples of impact sounds. The best way to reduce these sounds is to create separation.

In summary, the best way to reduce airborne sounds is by increasing the mass of the area you would like to soundproof. Reducing impact/vibration sounds is achieved by creating separation within the structure.

Reducing Impact and Airborne Sounds

By following some of these steps, you will ensure you get the best level of soundproofing for your room.

  • Mass/Density – Increasing the mass and density of the area you are soundproofing will block airborne sounds from transferring between rooms. You will increase the mass of walls and ceilings using materials such as soundproof panels or high-density acoustic insulation slabs.
  • Separation – Incorporating separation within the structure will reduce vibration and impact sounds transferring between rooms. Achieve separation by building independent stud walls and ceilings. If you don’t have the space in the room, you can use acoustic clips and resilient channels to decouple the wall and ceiling.
  • Absorption – Use materials that are going to absorb sounds. Acoustic insulation is suitable for sound absorption as it converts the sound waves into heat as it passes through the insulation. Dense mass loaded barriers will also dampen and absorb sound.

    If you have particular delivery requirements, please let us know at the point of order. It is possible to leave delivery instructions when you place an online order.

    Special Deliveries

    We can arrange to have orders delivered on Saturdays. A surcharge would be applied of an additional £50.

    How long will delivery take?

    We aim to despatch orders within 2-3 days of placing your order.

    If you order online, you will receive a confirmation email that we have received your order and it has been processed. We will then contact you once the order is just about ready to be dispatched to confirm a suitable delivery date. If you would like to discuss delivery times with us, please call 01423 339163. We recommend contacting us if you require the goods to be delivered on a specific date before placing your order.

    If you place an order over the weekend or on a Bank Holiday, this will be confirmed as an order on the first working day after the weekend or Bank Holiday.

    If you need goods in a hurry, give us a call. We carry most items in stock, which can be delivered quickly if required. Call 01423 339163.

    How will my order be delivered?

    The majority of orders we despatch are sent on pallets. We use a network of pallet distribution companies across the UK. All our pallet deliveries are kerbside deliveries. This means the pallet will be delivered as near to the delivery address as possible. Pallets are unloaded from the vehicles with a pallet truck. If it is possible the pallets can be dropped on driveways if they are accessible with the pallet truck.

    Pallet deliveries are typically made on 7.5-tonne vehicles that are similar in size to bin lorries. Occasionally larger vehicles are used. If you know of any reason why it might be difficult to deliver to your address with this type of vehicle, please let us know so we can pass the information on to the delivery company. Typical delivery problems can include parking restrictions, access issues for certain size vehicles, low bridges and overhanging trees. Call 01423 339163 if you are unsure.

    Unfortunately, the delivery drivers will not bring the goods into your property or unload the individual items from the pallets.

    Many of our heavy items require two people to carry them safely.

    All orders sent on pallets are wrapped and secured to the pallet to protect them while in transit. Once you have received your order, we would recommend storing the materials inside. If you plan on leaving your goods outside, you should use additional coverage to protect them from adverse weather conditions.

    Damaged or missing items

    If items are damaged or missing when your order arrives, you should sign damaged or missing items on the driver’s paperwork. Call 01423339163 to let us know of the issue to allow us to rectify the problem quickly.

    We might ask for a picture of the damage to speed up the process of arranging a suitable solution.

    To enable us to resolve any issues with your delivery, it is essential that you sign for your delivery when it arrives.


    Can I return items from my order? Yes, you can return unused items from your order that are in a salable condition. We can arrange to collect unused materials and bring them back to us. We would refund the cost of the items returned back to us, less the shipping cost incurred by the company collecting the items. The cost to return the goods would be confirmed at the point of arranging the return. The refund would be paid once the goods have been brought back and have been checked at our warehouse.

    Alternatively, you can arrange to return the materials back to us, and we will issue a refund once they have been received.

    *All prices displayed are exclusive of VAT @ 20%. This will be added at the end of the checkout process before you confirm your order.
