Refrigeration U: What Is A Screed?

To some folks, a screed might sound like a Star Wars villain. However, if you are installing a walk-in, a screed can be your best friend.

Most screeds are U-shaped vinyl channels that fit onto the bottom of a walk-in panel forming a seal against outside air and moisture. Screeds also hold in cold air and increase a walk-in’s performance and energy efficiency. They are essential if you have a floorless walk-in.

Other types of screeds include foam sealers which are constructed like a walk-in panel. Wall panels sit on top of foam sealers and cam-lock to them. To hold the foam sealers in place, plywood foam sealer guides are installed on the floor underneath.

Screeds also help align walk-in panels during construction. Once place on a concrete floor, they form a track to guide the placement of panels.

When installing screeds, remember that your floor must be level for a proper seal. Also, make sure the screed is square by confirming that the two dimensions between opposite corners are equal.
