Insulated sandwich panels have a lot of uses in construction. One main use is in the construction of cool rooms and freezer rooms, but they are useful beyond that as well. Beyond their general use for insulation, whether that’s sound or temperature insulation, in all sorts of building types, insulated sandwich panels work well in any situation where thermal insulation is needed. As already mentioned, insulation is useful in a general sense, but beyond being need in cold storage, it may also be needed to generally control and regulate temperature in processing facilities for food and even pharmaceuticals.

So it’s clear that insulated sandwich panels have a lot of uses.

Insulated Sandwich Panel Construction

Insulated sandwich panels are typically constructed of an insulator core with a metal or polymer outside. The insulator is sandwich between the outside layers, which is where the name “sandwich panel” comes from. The outside of the panel provides most of the strength and rigidity to the panel while the insulator provides insulation.

The insulator on the inside of a sandwich panel is usually made of polyurethane, polyisocyanurate, expand polystyrene, or mineral wool. All of these materials are generally good insulators, but they each have their pros and their cons, and they all have their uses based on how much insulation is needed, their exact use case, budget, and more. With this, the size and thickness of sandwich panels will vary depending on their use. A higher amount of insulation will obviously need a thicker panel, even if its insulating core is extremely efficient.

For example, mineral wool panels tend to have good fire resistance, and are usually used in situations where risk of fire is higher. The trade off with mineral wool, though, is that panels made from it tend to be more expensive than other materials. On the other hand, expanded polystyrene sandwich panels tend to be less expensive than other materials, but don’t have the higher insulation rating of other types of sandwich panels.

Why Use Insulated Sandwich Panels?

Insulated sandwich panels can make construction extremely fast and easy.

In a situation, for example, where a cool room needs to be built in a warehouse, it’s often faster and easier to build with insulated sandwich panels than it is to attempt to built walls and other partitions with enough insulation to do the job. Basically speaking, insulated sandwich panels are designed to be a partition and an insulator all in one.

Insulated sandwich panels are also designed to fit together easily during construction. What this means is that the construction of a facility, such as a cool room or processing facility, using sandwich panels is generally faster and easier. Since the panels themselves are efficient, it can also lead to an overall reduced need for materials as well. All of this combines to bring down costs in terms of both labour and supplies.

Of course, insulated sandwich panels don’t have the same load bearing capabilities as other construction materials, but they’re not meant to.

Insulated Sandwich Panels Work Like Any Other Insulator

There’s nothing special about insulated sandwich panels other than the fact that they’re designed and engineered to be great insulators while also being quick and easy to build with in situations where insultation is needed. Typically the insulation we’re talking about is thermal insulation, but they can also work well for soundproofing, protection again moisture, and in situations where building materials need to be fire resistant. It all depends on what the core and the outer materials are made of.

Since insulated sandwich panels are so varied, it’s usually best to work with an expert on what type of sandwich panel would be best for a particular project. This is where we can help.
