When you are in the market for a sandwich panel, the chances are you are likely to come across PIR and PUR insulation panels.
PUR means polyurethane and PIR means polyisocyanurate. PUR was popular in the past when it comes to making insulation panels. However, that has changed over time with PIR replacing it slowly. This can make someone want to know more about the two and how they differ.
The way to produce PUR and PIR is different. PUR is A polymer with repeating structural units of urethane segment made by the reaction of isocyanate and polyol. And PIR is a foaming material made by isocyanate reacts with polyether through catalyst.
How about fire resistance properties? Well, the PIR and PUR panels will have different fire-retardant properties. This is because PIR can withstand temperatures of 300 degrees C, while PUR can withstand temperatures of 200 degrees C.
As for insulation properties, PIR is also better. It comes with low thermal conductivity coefficient thus it would be able to keep the temperatures maintained easily within the desired range. You would not have to spend so much.
Both panels are also lightweight. This makes it easier to raise and install them. They are still both highly resistant to possible mechanical damage. Also, moisture cannot easily damage these panels making them good for various applications.
Figure 10 Workers Installing Sandwich Panels
PIR and PU panels are the most common options for those who want to set up a cold room storage. The reason is because of their thermal insulation properties. As an example, a PIR panel has a thermal conductivity coefficient of λ = 0.019. This is better than what you get with EPS sandwich panels.
The panels are also quite strong against any mechanical damage. You will mostly like the way these panels fit and stay strong against possible damages.
MGO or magnesium sandwich panel is a common choice other than the rockwool or EPS sandwich panel. There are various reasons why this is the case. They are mentioned below.
Yes. Sandwich panels can be designed to be specifically good for roofing applications. It is for this reason; you can also get sandwich panel roofs. They will be designed to look like the normal roofs in the market. From a distance, you might not even know that it is a sandwich panel used as a roofing material.
Sandwich panel corrugated shape designed for water drainage convenience. Connect to the gutter system. Usually the roof end be covered by steel or aluminium profile, no insulation exposed in air.
The way you handle the sandwich panels can sometimes determine if the panels will break or remain strong over the storage period.
There are various scenarios you should look at and how best to have the sandwich panels handled. Here are some of them;
Unloading the panels with a forklift
One forklift can handle sandwich panel less than 10m, pay attention to the lifting point must be at the center of the sandwich panel bundle. And necessary to use a plywood protect the sandwich panel, place it between forklift and the bundle. The forks of the machine should be longer compared to the sandwich panel width. This helps a lot with the balance of the panels.
When sandwich panel length exceeding 10m, you are required to use 2 forklifts to work at the same time. Note that the distance between the panels center and the forklifts shall be the same.
The upper surface of the forks should be smooth and clean. This is vital to prevent any possible damages to the panel surfaces.
You should never unload too many panels at any given time.
Storage of the sandwich panels
When you move sandwich panel piece by piece and by hand. Then move it vertically not horizontally.
Storage of the sandwich panels
Now that you have unloaded the panels, next is to store them properly.
You should always place them on a smooth level and dry & rigid surface.
You can also add support packages such as wood or polystyrene. This helps a lot in keeping the sandwich panels protected from the elements on the surface.
You should also place the sandwich panels at an incline of around 5%. This is vital to allow for the drainage of water in case there is condensation or leaks in the rooms.
You should not stack too many panels on top of each other. Zonsteel would have special instructions on how many panels can be stuck onto each other.
In case you have to store the sandwich panels for several months without using them, make sure they are stored under a shelter. Advise the stack time less than two months, otherwise the appearance and quality will be effected. The shelter is important to protect the panels from the elements such as sun rays, rain, and more. Also, ensure the room also has adequate ventilation.
In case the sandwich panel stack without any shelter, then put a tarpaulin on top to protect it from raining, especially the rock wool sandwich panel.
The measures mentioned above are just but a few things you should keep in mind. You can still do a lot more when you have the right guidelines. Consult with Zonsteel support team to get more help where necessary.

Sandwich panels are mostly precut to suit your needs. However, there is no doubt that sometimes you may want to cut the panels. Like make a hole for switch, for light, or for equipment. When you have to cut the panels at the project site, you have to follow are a few tips to ensure that you do it right.
Figure 12 Cutting Sandwich Panels
Sandwich panels can work great provided you also provide the right maintenance too. This is something people often leave out when they start using sandwich panels.
Sandwich panel maintenance can be divided into two phases. These phases are discussed below.
The installation period
If you want the panels to survive for long, they should always be installed based on the instructions as provided by the manufacturer. During this installation period, make sure that the metal chippings are removed from the surface of the sandwich panel. This is vital to keep them from scratching the surface.
The roof surfaces need regular cleaning. This is vital to remove metal objects such as saddle caps, nails, rivets, screws, and more.
The flashing elements are also known for holding dirt, metal chippings, metal dust, small screws, and more. Always inspect them and remove any foreign objects before applying a sealant to the elements.
If you want to learn more, please visit our website PUR/PIR Roof Panel.
Once you are done with the installation, it is best to clean the roof surfaces and gutters thoroughly. This ensures you remain with a clean sandwich panel.
The panels should be inspected for possible damages because you call it a wrap on the project. Sometimes if the installation is not done right, it can easily lead to damaged panels. In case a panel is damaged, you can always replace it.
Using the panels phase
This part is when you have been using the sandwich panels for a while. You still have to continue maintaining them if you hope to end up with a great looking sandwich panel.
This is the type of maintenance that can be done every six months. Check for any dirt and grime accumulation.
Check for any signs of leaks. Sometimes people do not seal their sandwich panels correctly. Apply additional sealant where you deem necessary.
Gutters can also be filled with multiple foreign objects. Such include plants, trash, sand, and dirt. In such a case, clean the gutters right to have a long-lasting sandwich panel.
Check the screws too. In case there are any lose screws, make sure they are re-tightened. This should leave you with sandwich panels fitting right and will not fall off easily.
It is possible that when constructing with sandwich panels, you might end up with some waste materials. These wastes are mostly derived from cut out pieces when you want to do a proper fitting. Sometimes they can be damaged panels too.
The damaged panels are those that cannot be used anymore due to breakage or any other reason. So, how are such panels disposed?
It will depend on your location. Some countries would have specific companies that are authorized to do such a job. This ensures that there is no pollution in the end. It will be best to consider what the local laws say about disposing of the sandwich panels.
Considering that the Zonsteel sandwich panels have to be transported to different countries, proper packaging is necessary.
Zonsteel will package the sandwich panels by protecting them with PE film. Then the packaged sandwich panels are attached to a steel pallet or a wooden pallet. In case they even have to be transported via sea, there should be enough protection for the sandwich panel to get to its destination safely.
The PE film is important to protect the surface from scratches. Once the sandwich panels are installed, the film can be removed to expose the beautiful look of the sandwich panel.

Polyisocyanurate (PIR) and Polyurethane (PUR) Sandwich Panels shares almost the same insulation characteristics, the main difference between them are as follow:
In general PIR and PUR rigid foam have almost similar chemical base and same insulating properties, they are produced by mixing several components in the metering machine or foam machine, the chemistry formulation of Polyisocyanurate (PIR) is primarily based on Methylene Diphenyl Di-isocyanate (MDI), these properties are also known as isocyanate, ISO or POLY (Polyethylene Glycol (PEG) and Polyester Polyol). However, PIR sandwich panels have a higher ratio of physical properties than Polyurethane (PU/PUR), this can dramatically improves the performance characteristics and fire behavior of PIR sandwich panels, and for example the ratio of isocyanate used for PIR foam is approximately 100:150, whereas Polyurethane (PU/PUR) contains only 100:110.
Polyiso rigid foam have great flame resistance characteristics over Polyurethane (PU), thanks to its rigid imide ring structures which slows the spread of flames and creates less smoke when burnt, on the other hand PIR Foam have higher fire performance than PU foam. PIR sandwich panels are normally classified as Class B1: Flame Retardant and have higher working temperature, while PU foam is normally produced as Class B2 (Normal Flammability building material). Hence, compared to PUR foam, PIR foam is more fire resistant and safer than PUR foam.
Polyisocyanurate (PIR) foam has superior closed cell structure (normally 97%) and hydrophobic nature, this offer them 0.9% water absorption, this rate is considered higher than Polyurethane (PUR) foam which have closed-cell structure, but their water absorption is normally below 2%, and thus, PIR sandwich panels have low water absorption and low permeability to moisture.
Rigid Polyiso foam (PIR) are dimensionally stable than Polyurethane (PUR), thanks to its excellent mechanical strength and cross-linked structure which offer exceptional stability to ageing, and high resistance to moisture and fire temperatures ranging from -200°C to +120°C, while, PUR can resist temperatures between -150°C and +80°C.
PUR sandwich panels
PIR insulated sandwich panels can be used under elevated temperature ranging from -40°C to 80°C (from -40°F up to 176°F), thanks to its temperature resistance properties of polyisocyanurate foams which are obtained using products of citric acid condensation.
PIR sandwich panels are completely resistant to moisture, thanks to their non-capillary & non-absorbent features which made them highly resistant to the overgrowth of mold, fungi, termites’ infestation, and vermin, whereas, their biologically stable properties and waterproof facing enable them to withstand extreme weather conditions.
One of the most important challenges facing the construction industry is the lifetime energy-efficiency of buildings, PIR sandwich panels are mainly designed to reduce the costs of heating and cooling for up to 50%, while they deliver great thermal performance, and ensure minimal thermal bridging through excellent air tightness and continuous insulation, hence they can contribute to LEED rating system and positively participate in zero-energy building standards.
Energy saving PIR sandwich panel
PIR sandwich panels are designed and manufactured in conformance with the EN - which specifies the requirements for factory made, self-supporting, double skin metal faced insulating sandwich panels. Furthermore, PIR sandwich panels should comply with the highest standards, whilst all components require rigorous testing and should carry a CE mark which confirms that all materials, labeling, and packaging meet the requirements of EU regulation.
Yes, PIR sandwich panels are eco-friendly building materials, they are made from the most sustainable and innovative polyisocyanurate foam (PIR) which are CFC, HCFC, and HFC free, on the meanwhile, they are 100% recyclable, reusable, and have a very low Global Warming potential. In addition to that, their great thermal insulation can ensure energy-efficient surfaces, and thereby saves heating, ventilation, air conditioning and maintenance cost.
Eco-friendly PIR sandwich panels
Polyisocyanurate (PIR) sandwich panels can last for over 70 years, they are mainly designed to provide high-performance building envelope that can last for decades without maintenance, thanks to their highly durable insulation that guarantee stable thermal resistance, while all material used doesn’t degrade over time.
The price of PIR sandwich panels in China ranges from $8.00 to $16.50, costs may vary according to many variables like panel thickness, size, facing materials, and customization options.
