⚠️ Special Order Product — Please allow additional lead time when ordering.

Ceramic-Reinforced Thermal & Acoustic Coating for Automotive, Marine & Industrial Applications

Al's Liner HNR is a proprietary, high-performance heat and noise reducer formulated from a blend of latex synthetic polymers — including acrylic, PVA, and vinyl styrene — and reinforced with ceramic micro spheres for exceptional thermal insulation, heat reflection, and sound deadening. Whether you're building out a custom vehicle, protecting a boat interior, or reducing cabin noise in a work truck, HNR delivers professional-grade results with the ease of latex paint application.

Keep your vehicle cool in summer, warm in winter, and quiet year-round.

Key Performance Benefits

• Reflects Exterior Heat by 45°F or More — Ceramic micro spheres actively reflect radiant heat, reducing interior cabin temperatures
• Superior Sound Deadening — Dampens road noise, vibration, and mechanical sound for a quieter ride
• Bonds to Virtually Any Substrate — Minimal surface prep required; applies to metal, wood, fibreglass, concrete, and more
• Easy Latex-Style Application — Brush, roll, or spray like standard latex paint — no special equipment needed

What Makes HNR Different?

Unlike traditional foam or mat-based sound deadeners, Al's Liner HNR is a sprayable, rollable liquid coating that conforms to complex shapes and reaches areas that rigid materials can’t. The ceramic micro sphere technology provides both thermal reflection and acoustic dampening in a single product — saving time, labour, and material costs on every job.
