StP Aero Sound Deadening 4.5m²/2.3mm

StP Aero Bulk Pack (Diamond Line Range)

Want the best balance between light weight and top-level noise reduction?
StP Aero is part of the Diamond Line range — a premium, self-adhesive sound-deadening material designed for cars, SUVs, and even performance builds where every kilo matters.

How much do you need?
One bulk pack (12 sheets, 4.5 m² total coverage) is enough to:

• Fully soundproof all four doors, or

• Cover the entire floor or firewall of a sedan or SUV.

Where to use it:

• Doors

• Roof

• Firewall

• Wheel arches

• Boot/trunk

• Bonnet/hood

• Interior trims

How to install:

1. Clean the metal surface — it must be dry, oil-free, and smooth.

2. Cut the sheets to size and peel off the backing.

3. Press firmly onto the surface using a roller.

4. If the temperature is above +15 °C, install directly.

5. If it’s cooler than +15 °C, lightly warm the material with a heat gun to improve adhesion.

Why it works:

• Multi-layer build: aluminium foil top (embossed with logo) + high-quality adhesive polymer base.

• Lightweight & efficient: delivers high vibration damping with less weight (max 3.5 kg/m²).

• Temperature resistant: performs from –45 °C to +100 °C, and withstands short bursts up to +190 °C.

• Non-flammable and safe for all vehicle types.

• Engineered for car audio: eliminates panel vibrations, improves bass response, and increases cabin comfort.

Pack Details:

• 12 sheets (each 750 × 500 mm)

• Thickness: 2.3 mm

• Total coverage: 4.5 m²

• Colour: Black

• Weight: Up to 3.5 kg/m²

• Bond strength: 4 N/cm (after temperature cycling)

• Flammability: ≤ 100 mm/min – non-flammable

StP Aero is the smart choice when you want maximum noise reduction with minimal added weight — perfect for daily drivers, performance cars, and professional sound system builds.
