Noico Red 150 mil (4mm) Car Heat and Sound Insulation - Quiet, Cool

In this review the Noico Red 150 mil (4 mm) closed-cell polyethylene foam is examined as a practical, vehicle-focused insulation solution for drivers who want a quieter, cooler cabin without heavy or smelly materials. The bottom line: this liner is for DIYers and professional installers seeking a lightweight, water-resistant alternative to rubber or polyurethane foam that reduces noise and improves thermal comfort. It is easy to cut and apply and provides measurable reductions in road and engine noise while resisting oil and petrol exposure.

Key Features

• Closed-cell PE foam: Provides an effective thermal barrier to keep heat out in hot weather and retain warmth when needed.
• 4 mm nominal thickness: Balances low weight with meaningful sound attenuation for panels, doors, and floors.
• Self-adhesive sheets: Simplifies installation so a single person can cut and stick pieces into tight vehicle cavities.
• Water and odor resistant: Does not absorb water and has no smell, unlike polyurethane foams, making it suitable for damp environments.
• Oil and petrol resistant: Withstands common automotive fluids so it can be used near fuel-affected areas with reasonable durability.
• Wide coverage: The package covers 36 sq ft (3.4 sqm) in 34 sheets sized 15.7 by 9.8 in, allowing work on multiple panels or a full interior refresh.

Who It's For

The Noico Red 150 mil liner is best for car owners, van converters, and audio installers who want a practical insulation upgrade without heavy materials. It suits people working in warm climates who need a thermal barrier that also reduces engine, road, and drivetrain noise.

It may be less appropriate for applications that require extreme heat shielding, like direct exposure to exhaust components or mufflers, where high-temperature materials designed for 450-1500 C are required. Those needing a thick damping butyl for structural panel deadening should consider butyl-based alternatives instead.

Pros & Cons

Pros

• Effective noise reduction and warmth, with customers reporting quieter cabins and reduced diesel rumble or turbo whine.
• Easy to cut and install compared with heavier or sticky butyl products, making DIY fitting practical.
• Resistant to water, oil, and petrol and free of odor, so it stays stable in automotive environments.
• Lightweight coverage of 36 sq ft lets you insulate large areas without adding bulk.

Cons

• Not suitable as a heat shield for exhaust components or other surfaces exposed to extreme temperatures.
• At 4 mm thickness it may not replace thicker rubber products where maximum structural damping is required.
