Tecsound vs Insoplast Acoustic Membrane: Selection Guide
Tecsound and Insoplast are high-density acoustic membranes used to reduce airborne noise transmission in building assemblies. Although both products add mass without requiring a thick construction layer, their material composition, listed applications and available product formats differ. The correct choice depends on the wall, ceiling, floor or roof assembly rather than the product name alone.
What Is Tecsound?
Tecsound is a high-density, flexible synthetic soundproofing membrane. SRD Infra lists Tecsound for airborne noise insulation in lightweight walls, partitions, panels, roofs and light roof systems. It can also be used to reduce impact noise and vibration in floors, limit rain or hail noise on metal and timber roofs, and support industrial noise-control applications such as machine rooms, cabins, pipes and metal-sheet damping.
The listed product range includes Tecsound 35, Tecsound 50, Tecsound 70 and Tecsound 100, with self-adhesive Tecsound SY variants also available. Product weight, thickness and installation format should be selected against the required acoustic build-up.
What Is Insoplast?
Insoplast is a reinforced, flexible, high-density elastomeric bitumen-based acoustic sheet. SRD Infra lists it as an airborne-noise insulator and vibration-reduction layer for plasterboard partition walls, laminated plasterboard ceilings and cavities combined with sound-absorbing materials.
Insoplast is particularly relevant when a dense acoustic barrier is required inside a wall or ceiling assembly. The supporting frame, plasterboard layers, cavity insulation, junction sealing and workmanship remain essential to the final acoustic performance.
Tecsound vs Insoplast: Key Differences
| Selection factor | Tecsound | Insoplast |
|---|---|---|
| Material description | High-density flexible synthetic soundproofing membrane | Reinforced elastomeric high-density bitumen-based sheet |
| Primary noise-control role | Airborne sound insulation, impact-noise reduction and vibration damping | Airborne sound insulation and vibration reduction |
| Listed building applications | Walls, partitions, panels, floors, roofs and light roof systems | Plasterboard partitions, ceilings and acoustic cavities |
| Industrial applications | Machine rooms, cabins, pipes, downspouts and metal-sheet damping | Confirm suitability against the proposed industrial assembly |
| Product variants | Tecsound 35, 50, 70 and 100, including self-adhesive SY options | Select the specified Insoplast grade and assembly requirement |
| Typical decision point | Broader wall, floor, roof or equipment noise-control requirements | Dense barrier layers in plasterboard wall and ceiling systems |
Choose Tecsound When the Project Requires
- A flexible soundproofing membrane for lightweight walls or partitions
- Acoustic treatment for metal, timber or other light roof systems
- Impact-noise or vibration reduction in a floor build-up
- Noise damping around machinery, cabins, pipes or metal sheets
- A listed self-adhesive membrane option for the proposed assembly
Consider Insoplast When the Project Requires
- A high-density bitumen-based acoustic barrier
- Airborne-noise insulation in plasterboard partition walls
- An acoustic membrane layer above a laminated plasterboard ceiling
- A dense barrier combined with sound-absorbing cavity insulation
- A wall or ceiling solution designed around the complete tested assembly
The Complete Acoustic Assembly Matters
An acoustic membrane cannot compensate for gaps, rigid sound bridges or poor detailing. Selection should account for the supporting frame, number and type of boards, cavity depth, absorbent infill, perimeter isolation, electrical boxes, service penetrations, doors, ceilings and flanking paths. The required laboratory or site acoustic rating should be confirmed before finalizing the system.
For renovation projects, available space and the existing substrate can influence whether a thin membrane layer is practical. For new construction, the complete wall, floor or roof build-up should be coordinated before procurement.
Information to Send for Product Selection
To review a Tecsound or Insoplast requirement, provide the application area, wall or ceiling build-up, target acoustic performance, available cavity depth, total quantity, project city and relevant drawings. For roof or industrial applications, also include the deck or substrate type and the primary noise source.

FAQs
Is Tecsound better than Insoplast?
Neither membrane is universally better. Tecsound has a broader range of listed wall, floor, roof and industrial applications, while Insoplast is focused on dense barrier layers in plasterboard partitions, ceilings and acoustic cavities.
Can Tecsound be used on roofs?
SRD Infra lists Tecsound for airborne-noise insulation on roofs and light roof systems, and for reducing rain, hail or wind noise on metal and timber roofs. The complete roof build-up must be reviewed.
Where is Insoplast commonly used?
SRD Infra lists Insoplast for plasterboard partition walls, laminated plasterboard ceilings and cavities where it is combined with sound-absorbing materials.
Do acoustic membranes work without cavity insulation?
A membrane adds mass, but final performance depends on the complete assembly. Framing, boards, absorbent infill, sealing, decoupling and flanking paths must all be considered.
