Tecsound Soundproofing Membrane

Tecsound Soundproofing Membrane – High-Density Acoustic Barrier

Tecsound is a high-density, bitumen-free synthetic soundproofing membrane designed to reduce airborne noise across walls, floors, roofs and ductwork. Combining viscoelastic properties with high mass, it delivers exceptional acoustic insulation without adding significant thickness. Its flexibility and tensile strength make installation simple on a wide range of building surfaces.

Why choose Tecsound

Outstanding sound insulation – up to 32 dB reduction when combined with lightweight partitions

Flexible and adaptable – conforms to uneven or curved surfaces

Self-adhesive sound-absorbing synthetic sheet

High damping capacity – ideal for metal sheets, partitions and ceilings

Fire rated – Euroclass B-s2,d0 to EN 13501-1

Durable and moisture-resistant – rot-proof with negligible water absorption

Easy to cut and fit – supplied in rolls for fast on-site handling

Eco-responsible manufacturing – ISO 14001 certified plant with verified Environmental Product Declarations (EPDs)

Typical applications

• Airborne noise control in plasterboard partitions and timber walls

• Soundproofing against airborne noise in ceilings and lightweight roofs

• Reduction of impact noise beneath laminated floors

• Damping of vibration and rain noise on metal decks and ducts

• Industrial soundproofing – machinery enclosures, pipes, and plant rooms

• Water absorption (24 h @ 23 °C): ≤ 0.03 %

Installation guidance

• Ensure the substrate is dry, clean and smooth (temperature +5 °C to +35 °C).

• Apply directly between two plasterboard layers or onto the base board of lightweight walls and ceilings.

• Fix mechanically or bond using Tecsound-compatible adhesive; joints should be butt-fitted with no overlaps.

• Seal any seams and perimeter joints to maintain acoustic integrity.

• For roofing or metal decks, install fleece-faced side upward with 50 mm overlaps and ensure full surface contact.
