Modern construction demands heightened fire safety measures,given their extensive adoption across office complexes, apartments, and retail spaces

These panels, made of two metal sheets with a polymer core,provide superior thermal efficiency while remaining easy to handle and install

but present significant combustion hazards without adequate fire protection

A proven strategy involves applying intumescent fireproofing materials

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

these coatings are minimally invasive and suitable for factory application or on-site re-treatment

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

In recent years, building codes have increasingly required fire-resistant treatments for exterior and interior wall systems

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

This added time can mean the difference between a contained incident and a catastrophic event

Professionals should only specify coatings certified to ISO, EN, or UL fire performance benchmarks

Regular inspections and proper application techniques are also essential to ensure long term performance

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