RHCB Series Felt Fire Seals Installation and Use Instructions
Introduction
When it comes to fire safety, windows are often overlooked compared to doors and walls. Yet, windows can act as a critical pathway for smoke and flames if not properly sealed. That’s where the fire door seal—in this case, the RHCB Series Felt Fire Seal for fire-rated windows—comes into play.
The RHCB Series is specifically designed for window fire sealing applications, offering easy installation, practical features, and reliable protection. In this guide, you’ll learn exactly how to install and use RHCB felt fire seals step by step.
What Are Felt Fire Seals for Windows?
Felt fire seals are narrow, fire-resistant strips installed around the perimeter of fire-rated windows. Their purpose is to:
Block the passage of smoke and flames in the event of a fire.
Maintain the integrity of the fire-rated glazing system.
Provide a reliable, long-lasting sealing solution.
By expanding under heat, these seals close the small gaps around fire-rated glass and frames, ensuring maximum protection.
Key Features of RHCB Series Felt Fire Seals
Adhesive Tape Head for Easy Application – Each roll comes with an adhesive tape head, making it quick and simple to apply around fire-rated window frames.
Clean Cutting and Reuse – If you need to cut the seal in the middle of a roll, cutting from the lower part of the adhesive backing preserves the tape head for next use.
Error Correction Made Simple – If you accidentally cut without leaving the adhesive tip, a quick fix is available. By carefully igniting the adhesive backing with a lighter and letting the flame extinguish, the adhesive separates cleanly from the protective layer. This allows you to peel it off without damaging the fire seal itself. (We still recommend the first method as best practice.)
Step-by-Step Installation Guide
Step 1: Prepare the Frame
Clean the window frame thoroughly to remove dust or debris. This ensures proper adhesion.
Step 2: Apply the Seal
Use the adhesive tape head to align the felt fire seal along the frame. Press firmly for secure attachment.
Step 3: Cutting Correctly
Always cut from the lower part of the adhesive backing when shortening the seal.
This method keeps the tape head intact for later use.
Step 4: Fixing Mistakes
If you lose the adhesive head, carefully use a lighter to ignite the adhesive backing.
Once extinguished, the adhesive will separate from the protective layer, allowing you to peel it cleanly without harming the fire door seal.
Practical Tips for Use
Store rolls in a cool, dry place to maintain adhesive quality.
Use sharp cutting tools for smooth, clean edges.
Do not overstretch the seal during installation.
