When installing sandwich panels in commercial or industrial buildings, one of the most critical yet often overlooked aspects is fire stopping at the joints. Sandwich panels are valued for their thermal efficiency and rapid assembly, but the gaps between panels can become channels for heat and combustion gases if not properly sealed. Adequate fire barriers at seams ensures compliance with building codes and substantially reduces fire-related risks.

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 continuous barrier that resists fire penetration that curbs smoke migration.

Fire-rated sealants are essential. These are specially formulated silicones or intumescent compounds that swell under intense heat, sealing voids to prevent fire spread. Choose a sealant that is certified to meet the relevant fire resistance standards such as ASTM E814 or UL 1479. Always ensure the sealant is non-corrosive to the panel surface to avoid long-term material breakdown.

In addition to sealants, non-combustible firestop insulation can be installed behind the panels in the joint cavity. 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 coated with intumescent sealant on all exposed edges.

For penetrations such as utilities breaching the panel assembly, use intumescent pipe sleeves or firestop wraps. These devices activate under heat to seal around 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 perform periodic maintenance audits. Over time, sealants can become brittle or detached, and کانکس ساندویچ پانل insulation can loosen over time. Annual inspections by qualified personnel can identify weaknesses before code violations occur. Documentation of all fire stopping materials and installation procedures should be preserved for liability and regulatory purposes.

Finally, always follow the specifications provided by panel and sealant suppliers. Using unapproved sealants or improper techniques can compromise the fire rating. Training for installers on proper fire stopping techniques is equally critical to system performance.

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 make all the difference in the event of a fire.
