The Faster, No Mess Smoke & Acoustic Solution

June 6, 2022 - Smoke and acoustic wall assemblies are often one of the most common partition types in today’s mixed-use and multi-family construction. While sealing joints for fire resistance in smoke partitions is not typically required by code, the passage of smoke should typically be mitigated by an approved material. When it comes to these assemblies, smoke passage isn’t the only concern for many owners and specifiers. Sound attenuation, energy efficiency, odor limitation, and infection disease control are often important design and construction considerations.

Hilti has developed a simpler to install, more productive, and more cost-effective solution to use with these non-fire-rated assemblies: CS-TTS SA Smoke & Acoustic Track Seal. CS-TTS SA is a head-of-wall, prefabricated seal that saddles the ceiling runner to provide a smoke and sound seal between the concrete slab above and the gypsum assembly below. This solution offers the opportunity to install the top of wall seal at the same time as the track attachment, which can significantly help reduce rework and additional trips to the joint compared to sealant. CS-TTS SA has been acoustically tested according to ASTM E90 and provides an acoustic performance up to 62 STC (related to specific construction). 

Firestop Installation for Membrane Penetrations

May 20, 2022 - Correct firestop installation is critical to helping achieve compliant and safer fire-rated assemblies – whether you are sealing a horizontal joint, filling an opening around a pipe through-penetration, or protecting electrical boxes. Hilti CP 617 Firestop Putty Pads, moldable firestop putty, helps protect electrical outlet boxes, junction boxes and washer/dryer boxes in common electrical applications.

Hilti has new training documentation available to help ensure electrical outlet box membrane penetrations are correctly firestopped when installing Hilti CP 617 Firestop Putty Pads. An installation guide provide guidance to support correct firestop installation, in accordance with the listing documentation, and installation review.

CP 617 Putty Pads: The Solution for Large Membrane Penetrations

November 30, 2020 - Hilti has designed and tested a specific listing to address “large membrane" openings with the use of our new Putty Pads CP 617. A penetration that only affects one side of a rated wall is referred to as a membrane penetration. Such penetrations occur frequently due to the installation of recessed electrical boxes. The International Building Code (IBC), which is adopted in most US jurisdictions, and the National Building Code of Canada (NBCC) 2015 and later require recessed fixtures be installed such that the fire resistance rating of the wall not be reduced.

One way to prevent boxes from reducing the wall’s fire rating and thus meet the code performance requirement is by using putty pads or other listed materials. Metallic electrical boxes that exceed 16 square inches (e.g., 4” x 4”) have the most stringent code requirements. In accordance with the IBC or NBCC, all recessed steel electrical boxes larger than 16 sq. in. must be protected in some manner, regardless of the spacing relative to other boxes on the opposite sides of wall. 
 
Hilti’s new UL/cUL Listing, W-L-7277, is designed to address recessed steel electrical boxes (18ga or heavier) with maximum dimensions of 20-18” wide by 42” high by 5-3/4” deep.

The department was first established in 1990 with a single Product Manager and has since grown to a comprehensive technical team of over 30 engineers and CAD designers, including some team members that are recognized by NFPA as Certified Fire Protection Specialists.

The primary focus of the team is producing engineering judgments and conducting firestop testing to develop and demonstrate the capabilities of Hilti’s innovative solutions. Since 1994, more than 2,900 actual tests have been designed, constructed and witnessed, producing well over 1,500 individual listed systems. In 2015, Hilti constructed a new state-of-the-art testing and development facility in Irving, TX, which has helped to support the Hilti Fire Protection Team meet the demand for new innovations, simpler and safer installation of firestop systems and to continue to focus on the importance of life safety in building construction. 

New Technical Article: An Introductory Review of Steel Protection

June 2, 2021 - While fire prevention has always been a priority, we have not been able to completely engineer building fires out of our lives. Thermal protection of structural steel currently includes many forms, one of which is Thin-Film Intumescent coatings. Increasingly, intumescent fireproofing finds its place on a wide array of projects such as hospitals, schools, office building, pedestrian bridges and even parking garages.

While limitations exist, steps are being taken by intumescent manufacturers – Hilti included – to widen the use of intumescent fireproofing. Innovative chemistry and refined application techniques are making intumescent coatings a more cost-effective alternative to other steel protection methods. Our newest technical article provides and introductory review of steel protection and the versatility of intumescent coatings.

Fire and airflow containment challenges in mission critical facilities

May 13, 2021 - With significant efforts devoted to risk mitigation in both new and existing data centers, correct firestop design and installation is essential. Data cable penetrations present the most unique challenge to firestopping – not only due to combustible cable jacketing that can burn away under fire conditions, but also because of cable re-penetration. 

Openings or pathways for data cables are continuously modified or upgraded through the lifecycle of a data center. This amplifies the risk even further as cable penetrations that may have initially been firestopped correctly could easily revert to being non-compliant and leave a facility exposed. Dive deeper into our new technical article, where we review the challenges with fire and airflow containment for mission critical facilities, with a focus on data centers.
