How to Install your Insulated Sandwich Panel?

Insulated Metal Panel is designed for appropriate and quick installation by limiting the number of needed exchanges and keeping projects on track by providing a single source to the building’s structure encloser.

Installation can be in a number of stages:

Unpacking and Transferring it to the Building Site

Physically or using a forklift are the ways through which Insulated Building Panel will be transferred. Transport lines and spreader blasts will be used to transfer a lengthier panel than six meters according to your requirement.

The exhibited splitting of belts for bundles ranging in length from 6 to 14 meters is 2-5 meters.

The Final Construction is Subjected to Quality Control

Before putting up the panel, you need to double-check that the design to which the Insulated Sandwich Panel will be attached is straight. Indeed, even the tiniest variation in execution might result in spillage at the board joints, resulting in the so-called “wave impact.”


Attach strips of PES sealing tape to the panel before it is fixed. It will be attached to the structure at areas where it will come into touch with the Sandwich Panel’s interior lining. The application of seals efficiently protects the liner from mechanical damage.

Sandwich Panel is Installed:

Introduce the core panel using fasteners that run through the length of the panel, all the way to the development component.

The Installation of Door, Window, and Skylight Profiles

Installation of small windows, doors, and skylight include locks that operate with their Insulated Sandwich Panel fixings without the need to purchase and install additional components.

Insulated Sandwich Panel may be cut using common metalworking tools in the local area.

Putting Together the Next Set of Panel

Areas where the panel is linked without a fastening (for example, a level junction between one panel and another on a segment, or a joint between a divider panel and a rooftop board) should be secured as well, using low-pressure polyurethane foam or butyl.

Treatments for Masking

The creation of veiling structures, such as joints, corners, wind supports, edges, or plinths, is the final stage of installation.


What is the Standard Work Procedure of Insulated Sandwich Panel?

Any work on Insulated Sandwich Panel follows the standard work procedure:

Make a large enough gap in the ISP for the line to pass through and apply slack. Where the ISP entry is too large to be created with an opening saw, a square or rectangular entrance is appropriate.

Install the line and apply line slacking, ensuring that the slacking is continuous during the ISP penetration. With the exception of any exterior metal cladding, all components of the slacking should be applied at this point.

Make blazing from two pieces of white Color Bond sheets that are similar to the ISP skin for either side of the ISP.

At the very least, ensure that the blaze covers the penetration by 50mm. Set up with dazzle bolts and silicone sealant between the glimmering and ISP. Get rid of any excess silicone sealant.

Make a small hole in the fabric and fill it with polyurethane foam to compensate for the deficiency. Reduce the amount of froth in the aperture by cutting it back.

If metal cladding has been determined, attach it to the slack pipework.

The obvious preoccupation joint is a popular tongue and notch joint, which keeps the fixation visible. It’s dependable, safe, and easy to set up.


What are the different types of Insulated Sandwich Panel?

What are the Environmental Features of the Insulated Sandwich Panel?

The inner and outer layer features of an Insulated Metal Panel will be resolved by the natural conditions to which your building is subjected.

  • The Insulated Metal Panel’s exterior sheet will not be affected by temperature changes produced by atmospheric pollution, wind, sun, and contact with dazzling rays, as well as compound and real collisions.
  • Because of the Sandwich Panel’s protective center, the temperature of the inward sheet is lower than that of the exterior sheet.
  • In this way, environmental variables and UV rays do not affect the inner sheet. Inward sheets, on the other hand, maybe sensitive to a range of physicochemical impacts, such as accumulation and compaction, as a result of the structure’s interior ecological circumstances.


What Selection of Insulation is used for the Insulated Sandwich Panel?

From the Sandwich Panel Selection material, you may select the appropriate protective material for the features and demands of your building.


Polyurethane is a rigid foam created by combining the main components ‘polyol and isocyanate’ with impetus materials at high stress and unusual circumstances.

Polyurethane has a closed-cell structure that provides excellent thermal insulation, dimensional stability, and water resistance. It does not cause germs to grow.

Because of its great compressive strength, it has excellent mechanical properties.


When the main segments of the polyurethane synthetically react at varied mix proportions, another macromolecular structure termed polyisocyanurate is formed.

Because of the differences in its manufacture, polyisocyanurate unbending froth is a variation of polyurethane with greater, enhanced fire resistance.

When compared to polyurethane, the amount of smoke produced in the event of a fire is far lower.

Mineral Wool:

Mineral wool is made by liquefying synthetic rocks and other solid oxides at high temperatures to form strands.

Mineral wool is the finest choice for sound insulation and fire resistance in your construction because of its stringy and open cell structure.

When compared to PUR and PIR, it has a higher protection value.

Extended Polystyrene (EPS)

Extended polystyrene is a petroleum-based thermoplastic polymer. Water fume is used to warm and expand the raw polystyrene material, which has a tiny granular pattern.

To expand the granules, pentane gas, a natural gas, is used. EPS is the most cost-effective and lightweight option among a variety of warm-weather protective options.


What is the Lifespan of the Insulated Sandwich Panel?

Filling insulated material between two metal surfaces frames the sandwich Insulation with composite material.

Insulated Sandwich Panel longevity and life is determined by careful planning to select the appropriate specialized determination of item parts based on the structure’s requirements, as well as the temperature and environmental circumstances in which it is situated.

Furthermore, the heap carrying capability of the Insulated Sandwich Panel, which should be calculated effectively based on the heap they will transport, should be designed with the insulated material coordinating with the structure’s requirements for increasing life span.

Light-Weighted Insulated Panels and their associated objects should be cleaned and regulated once a year after installation according to regulations and increase in life span.


How much does Insulated Sandwich Panel Cost?

The following material purchase expenditures can be taken as the best cost estimate:

  • An Insulated Sandwich Panel with a frothed polystyrene center costs around 15USD per m2 net.
  • An Insulated Sandwich Panel with a mineral-wood core costs as little as 20USD per m2 net.
  • An Insulated Sandwich Panel with a polyurethane core (PIR) costs around 15USD per m2 net.

Regardless of the cost of purchasing sandwich boards, the following should be included in the estimation:

  • The price of labor.
  • Containers and vacuum lifts are available for rent.
  • Frill acquisition (fasteners, flashings, seals) accounts for around 10-15% of the purchase price, all else being equal.
  • When the sandwich boards are stated by the customer, we provide transportation.



Before selecting Insulated Sandwich Panel, it is essential to choose the best core material for your building and its installation.
