What are Some General Rules for Installing your PU Sandwich Panel?
Some general rules for good installation of your PU Sandwich Panel are explained below:
Rules For Tooling
Soon after tooling it, all drill holes and cuts must be free from splinter using brushing.
Prevention Of Thermal Bridge
The inside facings act as a thermal bridge if it comes across a different environment with different temperatures and helps lose heat.
However, it can be problematic in the buildings outside and inside corners.
So it is necessary to eliminate the thermal bridges whenever possible or avoid developing thermal bridges.
Cutting of the internal facing at the end of the PU Sandwich Panel can lead to the elimination of the thermal bridge from the outside corner of the building.
The process should be carried one after installation is done. Make sure the cutting doesn’t affect the stability.
To eliminate inner thermal bridges, mounting thermal insulation is necessary between the framework and the end of the panel. Make sure the thermal insulation works properly and does not clasp.
Sealing Of Fasteners and Joints
To prevent air and vapor movement, joints in between should be tightly locked.
The PU Sandwich Panel should have no gaps. To remove gaps from it if any, fill it using insulating or sealant materials.
To avoid entrance of outdoor air or precipitation of buildings, seal the joints and fasteners.
Only the sealants and insulation mentioned in the drawing set should be used for sealing. Insulation should not be squeezed or lose its function.
Sealant should be applied on a dry and clean surface. If not clean, clean it before applying. Even application of a sealant is necessary on PU Sandwich Panel gaps and joints.
For more information, go through the instructions mentioned on the packaging and the safety sheet of your product.

However, you may use your product’s manual to check the exact or most suitable temperature for your specific unit.
How to Repair Damaged Coating of your PU Sandwich Panel?
The coating of the steel facing needs extra care. It can easily be changed due to ultraviolet radiation, air pollution, and temperature fluctuations.
If the PU Sandwich Panel is in direct contact with sunlight, the temperature can reach up to 60°C for light colors and 80°C for dark colors.
However, the temperature of the air in shades remains +28 °C. The possibility of damage increases at a higher temperature.
Microcracks can be observed if rainwaters drop on the heated steel coating. Polymer scratching also becomes easy in high temperatures as the hardness of polymer decreases.
The polymer coating vanishes out due to climate changes which make the surface matted and top polluted.
You may also experience bubbling, peeling, cracks, and corrosion of paints if the damage is extreme.
If PU Sandwich Panel is properly installed, has the light color of coating according to the climate then up to 25 to 50 years it will show no sign of aging. The light color coatings are more durable than dark color coatings.
If you encounter larger area damages they may be due to climate changes as climate changes are never local and are spread all over the area. The best way of repairing the damage caused by climate change is by painting it all over again.
Another main cause of damage in the PU Sandwich Panel is mechanical impact. It causes dents, scratches, and other damages but requires little repairing most of the time.

So early repairing of the damaged area is important. It can be done by restoring the protective coating by grinding.
The paint color of the repaired part will be different from the original color of the PU Sandwich Panel.
The difference can be easily visible when the repaired area will be large. So it is recommended to repair a damaged area soon after it is spotted.
The core of PU Sandwich Panels is mostly damaged during transportation, installation, or handling. Easily damageable among all are those which are made of the mineral wool core.
The only way to repair a panel having a mineral core is through panels that have no fire safety requirements. Fill polyurethane foam into the core after cutting out the damaged area.
The mechanical properties of the PU Sandwich Panel are not affected by little filling.
Cuts and Crossings
Cuts larger than 200mm affect the durability of the PU Sandwich Panel. So if you are making a cut check for its effects on durability.
If its structure is to be enhanced by adding any engineering communication or equipment, the level of safety requirements of the crossing must be the same as applied to the PU Sandwich Panel.
Distribution of the Loads
Protection of one that accesses the load is important. To equally distribute the load, cover the access area with mineral wool boards.
All the load should be shifted to the part that has the load-bearing frame. No additional load or access load is allowed to be placed. The design load should be taken into account.
How to Repair the Damaged Insulation of your Rockwool Sandwich Panel?
Improper cutting, installation, and transportation may cause the debonding of the steel core from the insulation core.
For small areas, flashings can be used. However, applying glue is necessary for larger areas debonding.
Single component polyurethane adhesive is recommended to be used for this purpose. Press the core after applying glue or put a weight on it to get it bound to the steel core firmly.
How to Clean your PU Sandwich Panel Surface?
You can water jet for cleaning the PU Sandwich Panel keeping its pressure up to 4Mpa. Directly point the water jet with a skew angle from 50 cm away for proper cleaning.
Avoid targeting the joints directly and make sure no water enters the joints.
The normal temperature of the water should be 30 C but in case of any fats or grease, the temperature can be increased to 50 C.
How to Clean Snow on your PU Sandwich Panel?
- All the tree leaves and dust should be cleaned once a year from the PU Sandwich Panel.
- The cleaning should only be done by plastic tools or tools with polymer coating.
- All tools with sharp edges should be avoided. The worker should wear shoes to avoid any damage to the PU Sandwich Panel or for its safety as well.
