Improving Fire Safety with Intumescent Coatings on Sandwich Panels

Ensuring fire protection is now a cornerstone of contemporary building design,especially with the widespread use of sandwich panels in commercial and residential buildings

Sandwich panels consisting of outer metal facings and an insulating polymer core,provide superior thermal efficiency while remaining easy to handle and install

but present significant combustion hazards without adequate fire protection

One effective solution is the use of intumescent coatings

which react to high temperatures by swelling and forming a protective char layer that insulates the underlying material

When applied to sandwich panels, these coatings significantly delay the spread of fire

enabling safer egress and enhancing firefighting effectiveness

In contrast to heavy plaster or cementitious sprays that burden structures

intumescent coatings are thin and can be easily applied during manufacturing or as a retrofit

It maintains the panel’s finish, color, and load-bearing characteristics without visual or physical compromise

Fire safety codes are tightening globally, requiring certified protection for کانکس ساندویچ پانل wall assemblies

establishing them as the preferred solution for regulatory adherence

Independent fire resistance tests report durations exceeding 1.5 hours for coated units

compared to uncoated panels that may fail in under 20 minutes

The extended resistance can transform a manageable fire into a survivable scenario

Manufacturers and builders are encouraged to select certified intumescent coatings that meet international fire safety standards

Ongoing maintenance and adherence to manufacturer guidelines are vital for sustained effectiveness

By investing in intumescent coatings, the construction industry can greatly reduce fire risks while maintaining the efficiency and design benefits of sandwich panels
