seam-logoDiscover the next generation of SmartSeam® suspended cover. The smart choice for protecting people, products and property from falling dust and debris.

After 20 years of innovation, the next generation of SmartSeam® is here! It is the only suspended cover that is compliant to the International Fire and Building Codes for containing dust and debris safely throughout North America. SmartSeam® keeps facilities operational during construction projects, while eliminating your liability in case of a fire.

That is why TuffWrap developed, and only uses, SmartSeam® for suspended cover projects.



Code Compliant

Re-engineered and tested to the highest standards, SmartSeam® is compliant with the International Fire and Building Code Standards, FM 4651, UL 723S and NFPA 13.

Protective Dust Cap

The only suspended cover solution with a protective dust cap over the heat reactive seam that provides extra dust and debris protection.

Heat Reactive Thread

A custom fusible thread has a lower melting point than other materials around it allowing the 6′ x 5′ panels to quickly open in case of fire permitting the sprinklers to activate as intended.

Strong 4-Ply Material

The four-layer polyethylene material is 6 mil thick and designed to provide the most puncture resistant and highest tear strength of any suspended cover available.

Innovative Scrim Design

If an accidental puncture occurs, the diagonal and perpendicular scrim orientation resists tearing and continues to provide protection.


Additives helps mitigate electrostatic discharges (ESD) thereby providing protection from combustible dust for data centers, clean rooms, electronics, grain elevators, battery manufacturing, and more.


Protects against mold, mildew, and bacterial growth which is critically important for the food and beverage, healthcare, and pharmaceutical industries.

Flame Resistant

SmartSeam’s innovative composition is tested and classified to reduce flame and smoke spread for temporary suspended ceilings. Approved for installation below sprinkler systems.


How does SmartSeam work?

What makes SmartSeam special is its heat-reactive seam, an advanced technology engineered by TuffWrap. When the seam is activated by the heat of a fire, the suspended cover panels open, permitting the sprinklers to function as designed.

After three years, close to one thousand tests, and extensive research and development, SmartSeam is Classified by UL to 723S for installation beneath sprinkler systems.  

Understanding the details. Having a product that is Classified by UL to 723S and therefore meets NFPA 13 is an important process that we as interior protection providers take very seriously. Here’s what you need to know:

Research and Development: SmartSeam is a proprietary product invented by an in-house team at TuffWrap. Not only is the seam critical to its functionality, the configuration of the poly panels and how it is installed are important as well. Every aspect of the final solution was taken into consideration in order for it to work properly.

Manufacturing process: SmartSeam is made in the USA. It is TuffWrap’s own invention and therefore we also designed and built equipment specifically to become the manufacturer of this product. Our machinery is “one of a kind” and not currently available for use anywhere else. We are inspected by an independent laboratory four times a year.

Meeting the standards: To meet NFPA 13, the suspended cover product has to be Classified to UL 723S for drop ceilings. In our industry, that is the only standard and test that qualifies.
