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

These panels, made of two metal sheets with a polymer core,offer excellent insulation and lightweight strength

may rapidly propagate flames if left untreated

Intumescent coatings represent a highly reliable mitigation approach

that undergo volumetric expansion under thermal stress, generating a low-conductivity char to preserve structural integrity

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

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

In contrast to heavy plaster or cementitious sprays that burden structures

intumescent layers are lightweight and compatible with both in-line production and post-installation retrofitting

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

Laboratory trials confirm that treated panels endure flame exposure beyond 90 minutes

where untreated equivalents collapse within 15–20 minutes

That extra window may prevent total structural failure and save lives

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

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

Adopting intumescent technology allows builders to enhance safety without sacrificing speed, cost-efficiency, or architectural flexibility
