• A 250-micron plastic vapor barrier with approximately 400mm overlapping joints.

• Proper sealing at wall-to-floor connections to reduce moisture penetration and air leakage.

Customized Floor Design

Cold room flooring should be coordinated with the room's insulation system, structural foundation and expected loading conditions. Forklift traffic, pallet movement, floor moisture and operating temperature all affect the final floor specification.

Kendall can coordinate floor insulation and surface configurations with the overall cold room construction plan.

Frost heaving can occur beneath large or low-temperature cold rooms when moisture in the soil below the floor freezes and expands. Over time, this expansion may cause floor movement, cracking or damage to the insulated floor structure.

A suitable cold room frost protection system helps reduce the risk of frost formation beneath the floor and protects the long-term performance of the cold storage facility.

Kendall considers two frost protection methods for applicable cold room projects:

1. Subfloor Ventilation Pipe System

A ventilation pipe system is installed beneath the cold room floor. The pipes are arranged to allow air circulation below the insulated floor structure.

Both ends of the pipes are left open to support airflow. This circulation helps prevent excessive frost accumulation beneath the floor.

This method is considered during the floor design stage, particularly for large cold rooms where sufficient space is available for underground pipe installation.

2. Electric Floor Heating Mats

Electric floor heating mats provide heat beneath the cold room floor to help prevent frost formation.

This option can be considered when the site does not have sufficient space for a subfloor ventilation pipe system.

Frost Protection System Selection

The appropriate frost protection method depends on the cold room operating temperature, floor structure, soil conditions, building layout and available installation space.

Kendall coordinates the frost protection arrangement with the floor insulation and cold room construction design to help protect the floor structure during long-term refrigeration operation.
