FROSTLOK™ Marine Ice Retention Upgrade System

Patent-Pending System | Lock in the Cold

Upgrade your fish box, cooler, or onboard compartment into a high-performance insulated storage system built for real marine conditions.

FROSTLOK™ is a modular marine insulation system designed to help ice last longer while creating a cleaner, more durable compartment surface.

What’s Included

• FROSTLOK™ CORE Tiles — 11.5” x 11.5” each
• SKINLOK Surface Squares — 11.5” x 11.5” each

The included SKINLOK Surface Squares are designed to overlap seams and create a smooth, sealed surface throughout the compartment. This helps prevent debris, fish residue, moisture, and buildup from becoming trapped between tiles or exposed foam edges.

SKINLOK Surface Squares can also be easily trimmed with scissors to reinforce corners, cover edges, fill small gaps, or customize difficult areas during installation—helping create a cleaner, more finished result with minimal waste.

Adaptive Fit Installation System

FROSTLOK™ features a patent-pending full-depth grid design that allows the CORE tiles to bend, resize, and conform to irregular spaces with minimal to no tools and virtually no material waste.

The progressive install system allows you to:

• position tiles gradually
• align sections precisely
• conform to curves and corners
• achieve cleaner fitment in tight compartments

The integrated 1” grid design also allows small sections of the CORE material to be easily separated and reused to help fill tight voids, corners, and irregular areas—helping create a more consistent insulated surface throughout the compartment.

Designed for cleaner fitment and easier installation in real-world marine compartments.

Built for Real Marine Use

High-Performance Insulation

3/4” closed-cell XLPE foam helps improve ice retention without excessive bulk.

Moisture & Odor Resistant

Closed-cell construction resists moisture absorption and helps prevent odors and material breakdown in wet marine environments.

Designed for Irregular Compartments

Conforms to curved walls, corners, fish boxes, coffin boxes, cooler compartments, and storage areas.

Durable & Easy to Clean

The SKINLOK Marine Surface System creates a cleaner, more finished compartment surface that is easier to wipe down after use.
