Which sandwich panel to choose for building cold stores and freezers?

There are materials on the market that can be used for constructing various types of facilities. Examples include PIR and PUR sandwich panels designed for cold stores and freezers. These panels are characterized by high gas tightness, resistance to mechanical damage, as well as moisture and fire resistance. What distinguishes these two types of panels from each other? Where can they be purchased? Read on!

PUR Panels

The most popular material used for building cold stores and freezers is the sandwich panel with a core made of polyurethane foam (PUR). This material is distinguished by excellent insulation properties, making it capable of maintaining the appropriate air temperature inside low-heat environments (down to -40°C). Moreover, the panel offers high tightness thanks to special labyrinth locks created during the milling process in production. It is also resistant to mechanical damage and weather conditions, making it ideal for environments exposed to dents, leaks, and the effects of mold or fungi.

PIR Panels

Another important factor to consider when constructing cold stores and freezers is gas tightness and related fire resistance. This is why PIR sandwich panels, which have similar properties to their PUR counterparts, are also widely used. However, PIR panels contain significantly more isocyanate, making them more capable of withstanding the effects of fire, high temperatures, and intense pressure for longer periods.

Which type of panel should you choose?

Both PIR and PUR sandwich panels are characterized by a low thermal conductivity coefficient. In both cases, the foam layer doesn’t need to be thick to provide optimal technical parameters. Furthermore, these materials are lightweight, easy to install, and resistant to damage, moisture, mold, and bacteria. If you want to use them for building cold stores or freezers, we invite you to explore the online store PlytaCMB.pl, where you can find panels available in various types and core thicknesses.
