St Louis, Missouri -- Convenience Products, which makes Touch 'n Seal insulating foams and sealants, has added two fire-rated sealants to its range: FireStop Gun Foam and FireStop 814 Sealant.
The company says both products have been tested and certified to be code-compliant for use in passive fire containment.
"Fire containment requires the use of multiple products working together," said Michael Sites, Touch 'n Seal's marketing manager, in a 30 Oct company statement.
"When a structure is being built, it's important to understand fire containment standards and use proper, industry approved materials to reduce the spread of smoke, flames and toxic gasses in the event of a fire. Our two new sealants meet or exceed UL and ULC standards for use as part of one and two hour rated firestop through-penetration systems."
Touch 'n Seal claims its FireStop Gun Foam is the only US-manufactured, one-component foam approved as a through-penetration firestop sealant for both commercial and residential applications. It is also UL (Underwriters' Laboratory) classified for use in common fire penetration joint systems.
The company says its red FireStop Gun Foam provides a permanent insulating and air sealing bond with many building materials including wood, masonry, insulating foam boards, metal, plastic, and sheetrock.
For HVAC, electrical, and plumbing applications, the foam prevents passage of smoke and fire when it is used to fill the void around pipes and conduits. It can also be used as fireblock material in space connections such as soffits and drop ceilings, partitions and stud walls at ceilings and floors, and in the tops and bottoms of stair stringers.
The foam's permanent seal against air and moisture infiltration will not shrink or decompose with age, the manufacturer claims, and FireStop Gun Foam prevents the passage of flame, smoke, hot gas, and water. Coloured red for easy identification as a fire sealant, the foam dries within minutes of application, and the company says after about 30 min, it can be cut if necessary. Depending on ambient temperatures, it cures fully in one hour.
