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).

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.

2020- 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. This listing provides designers and installers with a tested and listed system to install for larger membrane penetrations and now allows for a listed system to be installed more readily in the field.

2020- New Top Track Seal Installation Method and UL Firestop Systems

July 22, 2020 - We are pleased to announce a new method for installing Hilti Firestop Top Track Seal CFS-TTS, our pre-formed firestop solution for head of wall applications. Top Track Seal may now be post-installed, after wall framing and gypsum board is in place, by installing the material like a backer rod. Simply cut or tear the Top Track Seal in the middle and insert one half into the joint on each side of the wall to achieve a friction fit.

This allows the use of this innovative head-of-wall solution on projects where framing speed is critical and/or in remodel projects where the framing cannot be removed or replaced.

This installation method also results in improved performance and up to 3-Hr rated assemblies with the same great air-leakage and movement capabilities that Firestop Top Track Seal CFS-TTS typically offers. Find our two new firestop systems for this application here:


2020- Firestopping High Density Polyethylene Pipe

May 21, 2020 - Hilti has developed firestop solutions for an increasingly popular nonmetallic pipe: High Density Polyethylene (HDPE). Hilti firestop system C-AJ-2770 has been updated to accommodate HDPE pipe (SDR 11) that can range in size from 1-1/2” to 6”. The solution involves the “tuck-in” method using Hilti CP 648E Wrap Strip.

HDPE pipe uses the standard diameter ratio (SDR) system for sizing pipes. The SDR is the ratio of the pipe outer diameter divided by the pipe wall thickness. With the SDR system, pipes are sized by the outer diameter (OD), which stays constant. At a given OD, the wall thickness can change as indicated by different values of the SDR. It is important to keep in mind that these pipes are still described in terms of nominal diameter in North America, but in regions that use the metric system, the pipes are referred to in terms of the OD in millimeters. This variation with the SDR system of pipes is the main reason why the current lineup of firestop devices is not used – they simply do not fit as they are designed for pipes using the schedule system. Hence, the use of Hilti CP 648E Endless Wrap Strip is very common with pipes using the SDR system.

​ 2020- Through Penetration Firestop Systems Tested to Withstand Movement

April 24, 2020 - Over the life of a building, movement occurs - causing a penetrating item of a through penetration to move relevant to the hole, even when rigidly supported. This may impact the performance of a rated firestopping assembly. It’s important to have a method to consider movement and the impact on firestopping.

Hilti is the first manufacturer to have UL certified firestop systems with movement capability of the system tested and documented in the respective UL listings. We have successfully tested and certified a variety of our systems, from those that use sealants, such as FS-ONE Max, to preformed devices, such as the speed sleeve CP 653 or firestop blocks CFS-BL.
