Summary: Tunnel phenolic foam board offers superior thermal performance, moisture resistance, and fire safety, making it an essential solution for efficient insulation. Its lightweight and easy installation add to its practicality in various applications.

What is Tunnel Phenolic Foam Board?

Tunnel phenolic foam board is a high-performance insulation material made from phenolic resin. Its unique structure not only provides excellent thermal insulation but also makes it resistant to moisture and fire, thereby enhancing safety and durability in construction and industrial applications.

Key Benefits of Tunnel Phenolic Foam Board

1. Superior Thermal Insulation

This insulation material boasts a low thermal conductivity rating, often around 0.020 to 0.024 W/mK. Studies indicate that using tunnel phenolic foam board can reduce thermal bridging by 30%, significantly lowering heating and cooling costs.

2. Moisture Resistance

Unlike traditional insulation materials, tunnel phenolic foam board resists water absorption and mold growth. According to research, using moisture-proof insulation can prevent energy losses of up to 20%, making it essential for areas prone to dampness.

3. Enhanced Fire Safety

Tunnel phenolic foam board is renowned for its fire-resistant properties, achieving a Class 1 rating in fire tests. This ensures that it slows down flame spread, providing valuable time in emergency situations and enhancing building safety standards.

4. Lightweight and Easy Installation

With significantly lower weight compared to other insulation materials, tunnel phenolic foam board is easier to handle and install. This can reduce labor costs and construction time, making it an ideal choice for both residential and commercial projects.
