Screed Identification
• There are many styles of screeds used in floorless walk-in coolers and freezers. The types of screeds furnished with your
unit will be identified on the unit assembly drawing.
• Breaker strips (thermal breaks) are used to prevent heat transfer between the cooled side and the ambient side of a
concrete floor. Without these thermal barriers, heat transfer through the concrete layer is relatively rapid, causing a
greater likelihood of condensation and icing outside of the unit, as well as increased energy consumption and cooling load
on the refrigeration system.
CAUTION
When having a product installed with a thermal break, make sure that the contractor leaves the top of the
thermal break exposed for later inspection, not covered by concrete. If there are performance issues after
installation, it may be necessary to inspect the position and condition of the thermal break.
• Standard screeds are available in both vinyl (with integral floor coves) and metal versions. Vinyl screeds cannot be used in
outdoor applications due to potential issues with UV degradation caused by sunlight. Most thermal breaks are installed to
be level with the concrete surface. Heights for vinyl screeds are 1.5” or 4”, while metal screeds are available in various
heights as necessary for the application. Standard screeds are pre-cut with intended installation locations shown on the
assembly drawing.
