Sandwich panels are one of the most common and popular types of Insulation structures used for various types of constructions. This type of panel is specifically used for covering walls and roofs in industrial buildings.
Insulated Sandwich Panels are usually made of Thermo insulating materials such as Polyisocyanurate (PIR), rigid polyurethane (PUR), EPS (expanded polystyrene), Isophenic (IPN) or mineral wool insulation core, which is then sandwiched (hence the name) between a double layer of metal sheets on each side.
These kinds of panels are especially cost-effective because it acts as a singular solution for multiple types of constructions. There may be slight variation in the thermal insulation performance, sound insulation and fire resistance based on which material is used as core.
There are several reasons why Insulated Sandwich Panels are preferred for constructions and the primary reason is cost efficacy. It is seen that using Insulated Sandwich Panels saved costs on not only construction materials but for labour and shipping as well when compared with other types of panels. The cost however does vary according to the material of the core that is used along with the overall width of the insulated sandwich panels.
EPS or expanded polystyrene cores are the most cost-effective, budget-friendly version of Insulated cores. But if you are looking for long term service and performance with cost-effectiveness PIR or Polyisocyanurate would be the superior choice. Polyisocyanurate cores are much better at thermal conductivity thus making them the best choice for thermal cores.
Construction using traditional technology and masonry procedure takes around 250 days on average for completion. Whereas construction for stud partition (stud partitions are frames that are structured with Insulated Sandwich Panels) take 30 days approximately, thus being hugely time effective as well. This is mainly because stud partitions of Insulated Sandwich Panels only require assembling rather than building, unlike traditional masonry system. Insulated Sandwich Panels can be disassembled just as easily as well because of the tongue and groove design.
One of the advantages of using Insulated Sandwich Panels and stud partition construction is that it’s mostly a dry process, i.e it does not require water for the process of construction or even assembling. All you have to do is assemble the panels with the structure and screw in the outer cladding so it stays fixed.
Thus usage of such sandwich panels is not only time and cost-effective, but it is also good for the environment as it saves water, unlike traditional mason construction. Not only this but certain industries specifically require a dry, water-free construction process for their storage system to perform optimally. For example, pharmaceutical or wood industrial farms specifically need controlled levels of humidity.
Installation of insulated sandwich panels is relatively easy as we mentioned previously. Once the sheet panels are delivered they can be assembled easily by a proficient construction group, each panel taking about 8 to 10 hours at most.
The subframes require assembling with beams and posts following which the film protecting the insulated sandwich panels and fastened to the subframes. After this, all you have to do is seal the panels together. This process is far simpler and easier unlike the long-drawn process of traditional construction.
