Palusol vs. RYZW: Which Intumescent Fire Seal is Right for You?

1. Introduction

🔥 Did you know?
75% of fire-related property damage starts with unchecked gaps! Whether it’s tiny cracks around doors or small spaces between walls, fires can spread faster if these aren’t properly sealed.

That’s where intumescent fire strips come in — specialized seals that expand when heated to block fire and smoke from moving through your home or building. 🛡️

Today, we’re comparing two leading choices:

• ALUSOL STRIP from PALUSOL
• RYZW Series from RESASEAL

Both are designed to save lives and property — but depending on your needs, one might be the better pick. Let’s find out!

2. What is an Intumescent Fire Seal? 🔍

When exposed to high temperatures, an intumescent material undergoes a chemical reaction that causes it to swell many times its original size, forming a protective barrier.
This expanded layer:

• Blocks flames and hot gases from passing through gaps
• Delays fire spread, giving more evacuation time
• Protects doors, walls, and safes from early structural failure

Without a fire strip in place, even fire-rated doors can fail quickly. 🚪🔥

📚 Quick Fact:
Fire codes often require fire-resistant doors to include intumescent fire strips around frames for full certification.
