Car Sound Deadener Heat Shield 118x39 in Roll - Hood & Firewall

In this review the Abahub 118 x 39 in aluminum coated foam roll is examined as a practical and affordable way to reduce engine noise and block heat under the hood. The bottom line: this product is best for DIYers who want a lightweight, cut-to-fit heat resistant insulation and sound deadening layer that is simple to install and protects paint and components from engine heat. It works especially well when paired with a butyl vibration layer to improve overall noise control.

Key Features

• Size and coverage: The 118 x 39 in roll provides about 32 sq ft of coverage, enough for a single car hood or to cover multiple small panels.
• Aluminum coated foam: The reflective aluminum coating creates a heat barrier that reduces radiant heat transfer and protects finish on the hood.
• Workable thickness: At roughly 0.236 in thick the material can be cut with scissors for precise shapes and fits around hood and firewall contours.
• Water resistant: The foam resists water to help prevent trapped moisture and reduce the risk of rust on treated panels.
• Fire resistant insulation: The aluminum coating and foam construction provide a fire-resistant layer that blocks engine noise while offering thermal protection.
• Lightweight and portable: The folded roll is easy to handle during a DIY install and stores compactly until needed.

Who It's For

The product is aimed at car owners, truck and RV hobbyists who want a straightforward DIY solution for sound deadening and heat shielding without professional installation. It is a good fit for anyone adding thermal protection to the hood, firewall, doors or even using it as an appliance insulator.

It is less suitable for someone seeking a fully adhesive-backed, long-term factory-style fitment as stickiness and long-term durability receive mixed feedback; buyers expecting a permanent, peel-and-stick replacement for foam-backed factory parts may want a heavier-duty, adhesive-specific system.

Pros & Cons

Pros

• Effective at reducing engine noise and radiant heat when used alone or over a butyl vibration mat.
• Easy to trim with scissors and install around complex shapes because of the workable 0.236 in thickness.
• Water resistant and lightweight, which reduces concerns about trapped moisture and makes handling simple.

Cons

• Adhesion and long-term durability are mixed in customer reports, so extra fasteners or a butyl layer may be needed for secure long-term mounting.
• Not a direct replacement for thicker factory insulation systems where a bonded adhesive backing is required.
