When designing and constructing cold rooms and freezers, the flooring plays a critical role. These environments present unique challenges, and the type of screed used must withstand extreme temperatures while ensuring safety, durability, and energy efficiency.
Why Specialised Screeds Are Essential
Cold rooms and freezers require flooring solutions that can:
- Handle extreme temperatures: Standard screeds can crack under sub-zero conditions due to thermal stress.
- Prevent thermal bridging: Improper insulation can lead to energy loss and reduced efficiency.
- Resist moisture and frost: High humidity and frost exposure can damage unprotected screeds.
- Support heavy loads: Cold storage often involves heavy equipment and inventory.
Best Screed Materials for Cold Rooms
To meet these demands, the following screeds are commonly used:
- Polymer-Modified Screeds: Flexible and resistant to cracking.
- Epoxy-Based Screeds: Highly durable and moisture-resistant.
- Fibre-Reinforced Screeds: Strong and shrinkage-resistant, ideal for heavy loads.
- Insulated Screeds: These include insulation layers to enhance thermal efficiency.
Preparing the Floor for Screeding
Proper preparation ensures long-lasting performance:
- Insulation layers: Prevent thermal bridging and improve energy efficiency.
- Moisture barriers: Protect against frost damage.
- Level subfloor: A stable base prevents future cracking.
Key Considerations for Screed Thickness and Curing
Screed thickness impacts insulation and load distribution, but thicker screeds may require longer curing times. It is essential to allow gradual cooling to avoid thermal shock when the cold room is operational.
Maintenance Tips for Longevity
To keep cold room floors in top condition:
- Conduct regular inspections for damage.
- Repair cracks promptly to prevent further issues.
- Keep surfaces clean to reduce slip hazards.
