1. What is a PIR Sandwich Panel?

The PIR Sandwich Panel is made of polyisocyanurate solid foam core which is sandwiched between outer sheets that are made using either fabric or polypropylene.

The manufacturing of the PIR Composite Panel involves the contribution of blowing agent and MDI polyols (less than 5 GWP + ODP zero).

The purpose of this construction is to form polymers that are highly cross-linked.

The PIR Sandwich Panel works as a closed-cell possessing high thermal performance and excellent tensile and sheer strength.

Also, it is very lightweight which aids in the installation process. Areas having high humidity content have the best applications of the PIR Sandwich Panel. It is also suitable to be used in chill stores or freezers.

2. What are the Specifications of the PIR Sandwich Panel Plane?

The plane PIR Sandwich Panel Specification list includes:

  • Width: from 930 to 1130 (measured in mm)
  • Thickness: 50, 75, 100, 120, 150, 180, 200 (measured in mm)
  • Length: equal to less than 26 meters

3. What are the Properties of the PIR Sandwich Panel?

PIR Sandwich Panel properties include:

  • Coating Options: polyethylene (PE) coating, hydrophobic (HDP) coating, polyvinylidene fluoride (PVDF) coating, antistatic coating
  • Thickness: approximately 0.4 to 0.6 (measured in mm)
  • Construction Materials: prepainted galvanized iron (PPGI), stainless steel (SUS 304)

4. What are the Thermal Properties of a PIR Sandwich Panel?

PIR Sandwich Panel thermal properties are:

  • Coefficient of Heat Conductivity: from 0.018 to 0.024
  • Range of Heat Resistance: from -185 to +110 (measured in degrees centigrade)
  • Water Absorption: Equal to less than 3%

5. What is the Function of Roll Forming Machine in the Production of PIR Sandwich Panel?

An uncoller is a machine used to uncoil the PIR coil using hydraulic power which gets driving energy from the motor.

This also involves the placement of a rubber roller on the top of the uncoller to ensure that the coil does not undergo uncoiling all at once or over uncoil during the process.

This is then followed by a major step in which the sheet is passed through a roll-forming machine for properly shaping the coils.

The roll forming machine has two sub-units; upper and lower roll forming units. The main function of these units is to shape the steel sheet from both sides.

6. Why does PIR Sandwich Panel Production Involve Preheating?

The next step in the PIR Sandwich Panel production is the preheating step. Once the sheet is rolled and shaped, it is passed through the heating process.

A moderate temperature is maintained during this heating to prevent deterioration of the material.

Due to the temperature rise, the steel sheet’s heating process is activated.

This increases the force of adhesion between the steel sheet and the foam ensuring strong bonding between the two.

7. What Happens in the Metering Step of PIR Sandwich Panel Manufacturing?

PIR is then sent to the foaming machine which determinesits quality.

Catalysts are added to this machine, which determines the number of components accordingly.

Special liquid components are mixed in a specific amount and added to the metering machine for the production of polyisocyanate.

8. What is the Purpose of Foaming Portal and Pouring in PIR Sandwich Panel Production?

The mixing head is responsible for the production of oscillations which further help in gaining optimum application of the PIR mixture on the facing layer present on the lower side.

An A.C motor is used for providing energy for moving the mixing head.

This mixing head is further facilitated by a toothed belt which helps in the creation of free oscillating movements that are also programmable throughout the entire panel width.

The operation of the foaming portal is completely noise-free and does not cause any disturbance in the operating environment.

9. How do Heating and Block System Work in PIR Sandwich Panel Manufacturing?

PIR foam is kept between the two layers is chemically treated and cured at a specific regular temperature.

A heating system is used to provide the regular temperature required for this process by producing warm air.

A block system is a unit that prevents the leakage of the PIR Sandwich Panel which helps in the maintenance of the uniform foaming process.

A conveyor helps in the pressing of the foaming pressure and then conveying the PIR Sandwich Panel.

10. What is the Function of a PIR Sandwich Panel Cross-Cutter?

A PIR Sandwich Panel cross-cutter works as a cutting unit. It is used for perfectly cutting the parts used in PIR Sandwich Panel construction.

Talking about its construction, at the rear end of the cross-cutter, a gantry is placed whereas on the right is a saw unit installed.

An important thing here to keep in mind is the speed of the cutter. The speed must be in synchronization with the speed of the conveyer.

The operation of the cross-cutter can be either manual or automatic.

11. Why is a Cooling Conveyor used in Manufacturing PIR Sandwich Panel?

A cooling conveyor is a unit that helps in cooling down the heat present in the PIR Sandwich Panel after it has undergone several reactions generating heat.

This cooling is necessary to bring its temperature equal to the room temperature to avoid any further reactions and deterioration.

12. What are the Applications of a PIR Sandwich Panel?

PIR Sandwich Panel is a long-lasting and cost-effective option for various structures, from stadiums, malls, factories,and swimming pools.

Along with industrial structures and social spaces, it is becoming more popular as a product, with new applications.

These include military buildings, agricultural buildings, prefabricated housing, Jobsite buildings, silos, and residences. Some major applications of a PIR Sandwich Panel are:

14. How to Install your PIR Sandwich Panel?

PIR Sandwich Panel installation steps are:

Thorough Inspection:

Before installing the PIR Sandwich Panel, ensure that the structure is straight to which you will be attaching it.

Even small deviations that may occur in implementation are a cause of leakage mainly at the joints; which results in the so-called “wave effect” (which refers to the condition in which all the panels are not aligned on one plane).

Taking off the Protective Film:

You are advised to immediately removing the film before moving the PIR Sandwich Panel to the site of installation. Moreover, you are not advised to take off the foil after the installation of the panel.

The Fixation Step:

The best and most preferable assembly option is using vacuum lifts to safely transport the panels.

Use bolts for the installation of the first panel that penetrates through the entire thickness, to the end of the construction element.

Installation of Door and Window Profiles, As Well As Skylights:

Installation of window and door profiles requires a specific description. Skylights are also to be considered when it comes tothe roof panels.

Windows have locks that allow them to be attached to PIR Sandwich Panel without the need for additional parts to be purchased and installed.

A PIR Sandwich Panel can be easily cut on-site using common metalworking tools, such as:

  • Jig-saws
  • Saws that reciprocate
  • Nibblers

It is strictly not recommended to use high-temperature cutting instruments, like angle grinders.

15. How to Pack your PIR Sandwich Panel?

The packing machine helps in the packing of the finished PRI Sandwich Panel stacks. The packing process can be done either automatically or manually.

What you must consider is that the stacks should be properly aligned during the packing procedure.

Also, a good protective covering should be preferred for covering the stacks to ensure that they remain safe during loading, unloading, and transportation time.

16. What are the Basic Instructions for your PIR Sandwich Panel Stacking?

For stacking a PIR Sandwich Panel you can simply choose between automatic and manual stacking.

In the case of automatic stacking, a stacker is used, which works at the speed of production.

What you must keep in mind is to keep the speed of stacking less than the speed of PIR Sandwich Panel production.

It will automatically get your finished products stacked saving you a lot of hard work and time.

In the case of manual stacking, you can simply hire laborers for the task. This requires more effort and is more time-consuming.

The basic instructions for stacking your PIR Sandwich Panel involve:

  • Careful handling of PIR Sandwich Panel products to be stacked.
  • Skilled professional for this specific task.
  • Facilities for easy moving of the products and the final stack.

17. What are the Most Common Problems of a PIR Sandwich Panel?

When using a PIR Sandwich Panel, you might come across some of these common problems, including:

Costly Installation Modifications:

The major problem concerning to PIR Sandwich Panel is that its installation needs costly modifications.

Like, considering maker size and cutting it according to CAD blueprints using computer-controlled equipment.

Architects and builders must prepare for the electric wiring and plumbing.

And also for the doors, windows, and other architectural aspects, to avoid costly mistakes during PIR Sandwich Panel installation.

Extra Thick Making it Heavy and Bulky:

Workers may transport and handle tiny PIR Sandwich Panel by hand. But the one used for walls, ceilings, or floors is larger than eight by eight feet.

On the other hand, using a crane or forklift to lift and transport the panels to different places.

Non-Friendly Designs:

Architects should build a size-friendly PIR Sandwich Panel with no excessive jogs, bump-outs, or non-90 degree angles to save money and waste.

A non-friendly design can raise costs, increase waste, and, in some circumstances, reduce building or house performance.

Overall, boxy-shaped PIR Sandwich Panel houses and buildings are less difficult and less expensive to construct than structures with unusual curves and angles.

18. How to Solve the Problems of your PIR Sandwich Panel?

The solutions to some major PIR Sandwich Panel problems are:

Installation Issues:

The PIR Sandwich Panel assembly is a complex and professional step on which all operational expenses and building performance are dependent.

As a result, ask experienced businesses to validate their experience in the installation of your PIR Sandwich Panel along with taking advantage of a suitable warranty offer.

Damage and Corrosion Control:

In pharmaceutical industries when the inside of the building has an atmosphere witha very high water content because of the effects of abrasive detergents and washing, you are recommended to use PIR Sandwich Panel facing made out of stainless steel.

No doubt that it is an expensive solution however the only possible one to fight damage and corrosion in this case.

Load and Impact Control via Architecture:

The bearing capacity of a PIR Sandwich Panel is a significant feature since it is subjected to the effects of snow, wind, seismic activity, and other factors during operation.

When constructing building envelopes using a PIR Sandwich Panel, the criteria of “Loads and Impacts” must be considered.

For example, wind and snow load estimates for the same structure in different areas might change multiple times.

You must also consider structural characteristics, service loads, and building operating circumstances.

19. How to Maintain your PIR Sandwich Panel?

To maintain your PIR Sandwich Panel, two things must be considered:

  • The first is concerned with the time required to construct the PIR Sandwich Panel.
  • The second is concerned with the building’s usage, to which it has been put together.

General Instructions:

  • First of all, you should only choose a PIR Sandwich Panel that is not damaged.
  • The handling during the unloading operations from vehicles must be carried out with suitable means and appropriate protections, to prevent panels from being indented or scratched.
  • The current seals will have to be monitored to ensure that they are still airtight and watertight since this might lead to degradation.
  • The paint that may have been scratched accidentally will need to be preserved by retouching, which includes washing and painting. Large dents produced by collisions will need the replacement of the panel.
  • In the long term, smog accumulates on painted surfaces and may form a filth film, necessitating the use of water jets to clean the walls.
  • Periodic examinations of the PIR Sandwich Panel should be arranged to detect potential corrosion; if it is discovered, action should be done promptly, initiating preventive cycles to halt the process.

It is also used for constructing agricultural buildings like poultry houses, cowsheds, and pig houses, etc.

How Combustible is a PIR Sandwich Panel?

The combustibility of a PIR Sandwich Panel is lower in comparison to the PUR Sandwich Panel.

This low combustibility is maintained by coating an external carbon layer having pores for the protection of inner deeper layers. This prevents the inner layers from freezing.

What are the Criteria for Selecting PIR Sandwich Panel for Residential and Industrial Construction?

There are two major things included in deciding the criteria for selecting the PIR Sandwich Panel for residential and industrial construction; the class of combustibility and fire resistance.

The combustibility must belong to the G1 class whereas the fire resistance must lie in the E1 30 class. This ensures safe installation of PIR Sandwich Panel accompanied with maximum burning protection.

How to Set the Density of the Foam of PIR Sandwich Panel?

The density of the foam of a PIR Sandwich Panel must be higher near the face as compared to the midpoint of its height where there is free expansion.

This helps the foam rise to the upper face in a short time. The orientation of the core cells is kept in the foaming direction for properly orientated PIR Sandwich Panel production.

What are the Major Reasons for Thermal Loss of a Building which is then Prevented Using PIR Sandwich Panel?

Buildings encounter thermal loss problems which are prevented using PIR Sandwich Panel.

There are two major causes of this thermal loss, one is the transmission loss via floors, walls, and ceilings, the second is the ventilation loss as a result of permeable cladding which offers natural ventilation.

How does a PIR Sandwich Panel Reduce Transmission Loss?

For reducing transmission loss it is recommended to use a material that has low thermal conductivity.

PIR Sandwich Panel construction involves materials possessing low thermal conductivity making it efficient for reducing transmission loss.

How a PIR Sandwich Panel is Helpful in Reducing Ventilation Loss?

PIR Sandwich Panel effectively reduces ventilation loss by working as an efficient ventilation system.

This is further accompanied by the installation of corner locks which ensure its maximum tight packing. As a result, minimum ventilation loss is observed.

What is the Heat Capacity of a PIR Sandwich Panel?

The heat capacity of a PIR Sandwich Panel is 40 to 42λ.

This is considered a low heat capacity value which means that it has small space for heat storage as compared to other materials having high heat capacity.
