Question: Cables pull through rigid sleeves that go through fire rated wall, does anyone has a white paper or link to show how they fire caulk inside the sleeve (the gap between cables and sleeves)? Thank you.

You're looking for information on firestopping cable penetrations through fire-rated walls using rigid sleeves. Here's a breakdown of resources and information to help you

Key Concepts and Best Practices
Firestopping Systems

The goal is to restore the fire-resistance rating of the wall after it's been penetrated. This means preventing the passage of flames, smoke, and hot gases.


Listed Systems

Crucially, you can't just use any fire caulk and hope for the best. Firestopping needs to be done using tested and listed systems. These systems are tested under fire conditions (ASTM E814 / UL 1479) to ensure they perform as intended. The manufacturers of firestopping products publish these tested systems in their product catalogs and online.

Matching Materials and Applications

The specific system you use will depend on:


The fire rating of the wall

(e.g., 1-hour, 2-hour)

The type of wall

(e.g., concrete, gypsum board)


The type and size of the sleeve

(e.g., steel, PVC)

The type, size, and quantity of cables

(e.g., communication cables, power cables, the number of cables)


The annular space

(the gap between the cable(s) and the sleeve's inner diameter)

Proper Installation

Following the manufacturer's instructions
exactly is paramount. That includes: Proper cleaning of the surfaces. Applying the correct depth of fire caulk. Using any required backing materials (e.g., mineral wool, fire-rated foam). Maintaining the correct compression/density of the firestop material.

Where to Find Information


Firestop Manufacturers' Websites

This is the
best place to start. Reputable firestop manufacturers like these have comprehensive resources:

Hilti

[https://www.hilti.com/](https://www.hilti.com/) (Search for "firestop cable penetration," "firestop through-penetration," or use their firestop selector tool.)

3M

[https://www.3m.com/](https://www.3m.com/) (Search for "3M Fire Protection Products" or "fire barrier solutions.")


Specified Technologies Inc. (STI)

[https://www.stifirestop.com/](https://www.stifirestop.com/) (Has an excellent system search function.)

Rectorseal

[https://www.rectorseal.com/](https://www.rectorseal.com/) (Look for their Metacaulk line.)


Passive Fire Protection Partners (PFPP)

[https://pfppartners.com/](https://pfppartners.com/) (Distributors who can provide technical support).

Tremco

[https://www.tremcosealants.com/](https://www.tremcosealants.com/)

What to look for on these sites



Product Catalogs

Downloadable PDFs that list their firestop products and, most importantly, the tested systems for each product.

System Selection Tools

Many manufacturers have online tools where you can input the details of your penetration (wall type, cable type, sleeve type, etc.), and it will suggest the appropriate firestopping system.


Installation Instructions

Detailed, step-by-step instructions for each listed system. These are critical.

Technical Data Sheets (TDS)

Information on the properties of the firestop material.


Safety Data Sheets (SDS)

Information on the safety of the material.

Videos

Some manufacturers have videos demonstrating proper installation techniques.


CAD Drawings/BIM Objects

For including firestopping details in your construction drawings.2.

UL Online Certifications Directory

[https://www.ul.com/](https://www.ul.com/) (Search for "UL Product iQ") You can search for firestop products and systems by manufacturer and model number. This confirms that the product is actually UL-listed.3.

Intertek Directory of Listed Products

[https://www.intertek.com/](https://www.intertek.com/) Similar to UL, Intertek is a testing and certification organization. Search for firestop products and systems listed by Intertek.4.

NFPA (National Fire Protection Association)

[https://www.nfpa.org/](https://www.nfpa.org/) While NFPA doesn't list specific products, they publish codes and standards related to fire protection, including:

NFPA 101: Life Safety Code

Addresses firestopping requirements.


NFPA 70: National Electrical Code (NEC)

May have requirements related to electrical cable penetrations.

NFPA 80: Standard for Fire Doors and Other Opening Protectives
Provides detail on the types of systems.5. IBC (International Building Code)

Often references ASTM E814 (UL 1479) for testing firestop systems.

Example Scenario and Search Strategy

Let's say you have: A 2-hour rated concrete wall. A steel sleeve. Multiple Cat6 communication cables. You want to use Hilti fire caulk.Here's how you'd find the right system:1.

Go to Hilti's website.
2. Search for "firestop cable penetration" or use their system selector tool.3. Filter the results

Wall Type: Concrete Penetrant: Cables (specifically, communication cables) Sleeve: Steel Fire Rating: 2-hour Manufacturer: Hilti4.

Review the listed systems.
You'll see options that specify the exact Hilti fire caulk to use, the required depth of caulk, whether any backing material is needed (like mineral wool), and the maximum number and size of cables allowed.5. Download the installation instructions for the system you choose. Follow them precisely.Important Considerations



AHJ (Authority Having Jurisdiction)

The local building inspector or fire marshal has the final say. Consult with them if you have any questions or uncertainties.

Trained Installers

For critical applications, consider using firestop installers who are trained and certified by the firestop manufacturers. This helps ensure proper installation.


Documentation

Keep records of the firestopping systems used, including the manufacturer's name, product name, system number, and the date of installation. This is important for future inspections.*

Maintenance

Firestopping should be inspected periodically to ensure it remains in good condition. Damage or deterioration should be repaired promptly using the original firestopping system or an approved alternative.

In summary, there isn't a single "white paper" that covers every situation. The key is to find the tested and listed system from a reputable manufacturer that matches your specific application and to follow the manufacturer's instructions carefully.
Start with the manufacturer's websites, use their system selection tools, and download the installation instructions. Flag for review
