INSULATED SANDWICH PANEL, WHAT IS THE WORKING TEMPERATURE RANGE OF INSULATED PANELS

WORKING TEMPERATURES RANGE OF PUR, PIR, ROCK WOOL INSULATED SANDWICH PANELS

In this blogpost we are going to shed light on what is the behaviour of insulated panels towards temperature and what is the working temperature range of insulated panels.

WHAT IS THE BEHAVIOUR OF INSULATED PANEL TOWARDS TEMPERATURE?

Recently, a new customer asked for some explanation about the upper working temperature limit of a PUR insulated sandwich panel.

He had some concerns about placing an oven in a laboratory made of structural sandwich panel.

Information over the behavior of insulated sandwich panel towards temperature is quite scarce, therefore we want to clear this point up.

What do we mean by “temperature”? The temperature of the surrounding environment, as the heating produced by the sunlight or by a running engine, e.g. an evaporator or an oven.

Permanent temperature hikes on a metal sandwich panel can lead to dimensional changes, loss of shape and strength, thermal decomposition and even worse consequences.

Therefore, in certain applications, we suggest to pay attention to these working temperature limits of the insulated sandwich panel.

The information that we suggest to keep into consideration reports the lower and upper temperature application limit in ° C and °F.

It states the temperature that an metal sandwich panel can usually be loaded without destruction or change occurring.

The duration of heating plays an important role over an insulated metal panel that permanently heats up. For example, in a roof application under the sunlight.

The temperature application limit does not keep into consideration the behaviour of the material in case of fire.

WHAT IS THE WORKING TEMPERATURE RANGE OF INSULATED PANELS?

THE WORKING TEMPERATURE RANGE IS:

  • PUR insulated sandwich panels from -40°C up to 80°C (from -40°F up to 176°F);
  • PIR insulated sandwich panels from -40°C up to 80°C (from -40°F up to 176°F);
  • Rock Wool insulated sandwich panels from 0°C up to 100°C (from 32°F up to 212°F).

Altougth these temperature ranges may appear conservative, we prefer to use this approach as a general guide line.

As metal insulated panel is a product that has a long life-span in a normal environment, it’s very important to keep this info into consideration when planning the purchase of it.

We encourage you to ask us further info on your specific case.
