If your car feels too noisy on the road, you’re not alone. Road noise, tyre roar, and vibrations from metal panels can make driving tiring. The good news is that with the right materials, you can significantly reduce noise and improve overall comfort.

In this guide, we’ll show you how to soundproof a car step by step using products from carinsulation.co.uk.

What Causes Noise in a Car?

Before starting, it helps to understand where noise comes from:

• Road and tyre noise (floor & wheel arches)
• Vibration of metal panels (doors, boot, roof)
• Wind noise (doors and seals)

To fix this, we use a layered approach:

1. PeaceMAT XR Sound deadening (butyl) – stops vibration
2. UK Liner or SOShield Foam insulation – absorbs sound and adds comfort

---

What You Will Need

• PeaceMAT XR – sound deadening mat
• SOShield – insulation + sound absorption
• Roller tool
• Knife/scissors
• Cleaning cloth

---

Step 1: Prepare the Surface

Before applying anything:

• Remove trim panels and carpets
• Clean all metal surfaces thoroughly
• Ensure surfaces are dry and grease-free

👉 This helps the material stick properly.

---

Step 2: Apply Sound Deadening (PeaceMAT XR)

Apply PeaceMAT XR directly to the metal:

• Cut sheets to size
• Stick onto panels (doors, floor, boot, arches)
• Use a roller to press firmly

💡 You only need 50–70% coverage — full coverage is not required.

Result:

• Reduces vibration
• Cuts road and tyre noise

---

Step 3: Add Insulation Layer (SOShield)

Next, install SOShield over the panels:

• Apply over sound deadening or directly onto panels
• Cover large areas (doors, roof, boot, sides)
• Ensure neat coverage

Result:

• Absorbs sound
• Keeps heat in during winter
• Reflects heat in summer
• Acts as a vapour barrier

Step 4: Focus on Key Areas

For best results, prioritise:

Doors

• Big improvement in overall cabin noise

Floor & Wheel Arches

• Reduces tyre and road noise

Boot Area

• Helps with echo and rear noise

Roof

• Reduces rain noise

---

Step 5: Reassemble Interior

Once installed:

• Refit carpets and trim
• Ensure everything is secure
