Ensuring fire protection is now a cornerstone of contemporary building design,particularly as sandwich panels dominate both industrial and housing projects

Sandwich panels consisting of outer metal facings and an insulating polymer core,deliver outstanding energy performance without adding excessive weight

may rapidly propagate flames if left untreated

One effective solution is the use of intumescent coatings

which expand dramatically when exposed to heat, creating a carbonaceous barrier that shields the substrate

Coating sandwich panels with these materials substantially slows flame propagation

allowing building occupants to exit safely while emergency crews gain critical response window

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 load-bearing characteristics without visual or physical compromise

Modern regulatory frameworks now mandate fire-rated solutions for both external cladding and internal partitions

positioning them as the ideal, standards-aligned option

Testing has shown that coated sandwich panels can withstand fire exposure for کانکس ساندویچ پانل over 90 minutes

compared to uncoated panels that may fail in under 20 minutes

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

It is imperative to use products validated by global fire safety authorities such as ASTM or BS

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

This strategic investment safeguards lives and assets while preserving the logistical and aesthetic advantages of modern panel systems
