When installing sandwich panels in commercial or industrial buildings, one of the most critical yet often overlooked aspects is sealing panel seams against fire. Sandwich panels are valued for their energy-saving performance and streamlined installation, but the gaps between panels can become pathways for fire and smoke if not properly sealed. Effective fire stopping at these joints ensures compliance with building codes and significantly improves occupant safety.

The first step is to identify the type of joint being used. Common joint types include interlocking, lapped, and flush seam configurations. Each requires a slightly different approach to fire stopping. Regardless of the joint type, the goal is to create a integrated smoke and flame barrier that curbs smoke migration.

Fire-rated sealants are essential. These are specially formulated silicones or intumescent compounds that expand when exposed to high temperatures, creating an impermeable barrier against combustion. Choose a sealant that is listed under NFPA 285 and IBC standards. Always ensure the sealant is chemically safe for the panel substrate to avoid long-term material breakdown.

In addition to sealants, non-combustible firestop insulation can be installed within the seam voids. These materials are inherently fire-resistant and enhance thermal containment. When using batts, make sure they are compressed slightly to fit snugly without gaps, and then sealed on both sides with fire-rated sealant.

For penetrations such as cables, کانکس ساندویچ پانل ducts, or plumbing lines intersecting seams, use intumescent pipe sleeves or firestop wraps. These devices expand when exposed to flame to encase the penetration, maintaining the integrity of the fire barrier. Never leave penetrations unsealed, as they create direct pathways for fire.

It is also important to inspect all fire stopping installations regularly. Over time, sealants can deteriorate or lose adhesion, and insulation can shift or degrade. Scheduled audits by licensed contractors can catch these issues before they become safety hazards. Documentation of all fire stopping materials and installation procedures should be kept on file for inspections and audits.

Finally, always follow the recommended protocols from all product manufacturers. Mixing incompatible materials or deviating from installation instructions can compromise the fire rating. Training for installers on proper fire stopping techniques is as vital as selecting certified products.

Proper fire stopping at sandwich panel joints is not just about meeting regulations. It is a non-negotiable safety priority. Investing in meticulous firestop application can turn potential disaster into controlled containment.
