VB-VK Commodore Firewall Insulation

Pre‑Cut Firewall Insulation Pad – VB to VK Holden Commodore

Over time, the original firewall insulation in VB–VK Commodores deteriorates, crumbles, and breaks down, leaving the cabin exposed to excess heat and engine noise. Once the factory pad fails, thermal and acoustic transfer increases noticeably, reducing driving comfort. Whether your original insulation is damaged, missing, or simply past its service life, Car Builders’ premium pre‑cut firewall insulation pad is the perfect OEM‑style replacement, restoring comfort and protection to factory standards.

Designed specifically for VB, VC, VH, VK Commodore models, this pad delivers a precise fit and straightforward installation.

Upgrade Your Firewall Insulation with These Add‑Ons

1. Sound Deadener Sheets – Extra Noise Reduction

For enhanced acoustic control, pair your firewall insulation with Car Builders Sound Deadener Sheets. These vibration‑damping sheets reduce structure‑borne noise, minimising sound transfer from engine and road vibrations into the cabin.

• Includes 6 sheets (300mm x 500mm)

• Dampens vibrational noise from the engine bay

• Boosts the effectiveness of the firewall insulation

Installation:

• Map out sheet placement before installation to ensure full coverage.

• Clean the firewall thoroughly to remove dirt and grime.

• Apply the Sound Deadener Sheets directly to the firewall, then install the pre‑cut insulation pad over the top for a layered thermal and acoustic barrier.

2. Application Roller – Ensure Long‑Lasting Adhesion

For optimal adhesion and longevity, use the Car Builders Application Roller during installation. Proper surface preparation and even pressure ensure a strong, long‑lasting bond for both Sound Deadener Sheets and the Firewall Insulation Pad.

• Ensures even pressure across the material

• Handle doubles as a convex tool for shaping products into contours

• Radiused wheel prevents marking or tearing—common with cheaper square‑edged rollers

Key Features of the Firewall Insulation Pad

• Vehicle‑Specific Fit – Precisely cut to match the firewall contours of VB–VK Commodores for an easy, factory‑like installation.

• Premium Underbonnet Insulation (PUBIN) – Made from durable needle‑punched polyester, engineered to resist heat, moisture, and wear.

• Self‑Adhesive Backing – No messy glues or fasteners—just peel and stick.

• Superior Cabin Comfort – Reduces engine noise and heat transfer for a cooler, quieter drive.

• Resilient & Washable – Withstands high‑pressure washing without deterioration.

• Non‑Ignitable & Heat Resistant – Rated to 405°F (207°C) for reliable thermal protection.

• Sleek OEM Appearance – Finished in 100% black for a clean, factory‑correct look under the bonnet.

Enhance Your Firewall Protection Further

For extreme heat applications—such as turbocharged setups or areas where components sit close to the firewall—reinforce your insulation with Car Builders Peel & Stick Heat Shield. A common approach is to install the firewall pad normally, then apply Peel & Stick Heat Shield only in high‑heat zones for targeted protection.

This high‑performance barrier uses needle‑punched fibreglass with a durable aluminium face, tested to withstand 475°F (246°C) for 30 hours with no failure.

Easy DIY Installation – Pro Tips & Tricks

Preparation:

• Clean the firewall thoroughly using a wax and grease remover for strong adhesion.

• Trial‑fit the insulation pad before peeling the backing to confirm alignment with all holes and contours.

Installation:

• Apply Sound Deadener Sheets First (If Using) – Roll them firmly onto the firewall.

• Start at the Centre – Peel a small section of backing and anchor the pad in the middle.

• Secure in Sections – Work outward gradually, peeling as you go. Avoid stretching the material.

• Roll Down Firmly – Use the Application Roller to ensure even pressure and a strong bond.
