PUF Sandwich Panels

PUF (Polyurethane Foam) panels are a type of sandwich panel used in construction and insulation applications. These panels consist of a rigid core of polyurethane foam sandwiched between two layers of metal or other durable materials. The core material, polyurethane, is known for its excellent thermal insulation properties, structural strength, and lightweight characteristics.

Key Features:

Thermal Insulation

PUF panels provide superior thermal insulation, significantly reducing heat transfer and improving energy efficiency.

Lightweight

The lightweight nature of PUF panels makes them easy to transport and install, reducing construction time and labor costs.

Structural Strength

Despite being lightweight, PUF panels offer high structural strength and durability.

Versatility

VersatilityPUF panels can be used in a variety of applications, including cold storage, industrial buildings, residential buildings, clean rooms, roofing, and cladding.

Fire Resistance

PUF panels can be treated to enhance their fire-resistant properties, making them safer for various applications.

Moisture Resistance

These panels have low water absorption, ensuring they remain effective in humid conditions.

Sound Insulation

PUF panels also provide a degree of acoustic insulation, helping to reduce noise levels.

In summary, PUF panels are a versatile, efficient, and cost-effective solution for various construction and insulation needs, offering superior thermal insulation, structural strength, and ease of installation.

PUF Panels Technical Parameter:
