Foam core composite panel

Types of Foam Core Composite Panel

A foam core composite panel is a type of sandwich panel. This consists of two outer layers (or skins) and a foam core in the middle. This panel is lightweight but has high structural integrity and thermal insulation. The core material can vary depending on the required insulation value, cost, and weight. Here are the different types of foam core composite panels:

• Polyurethane (PU) Foam Core Panels

  Polyurethane foam core composite panels are widely used. They are super lightweight, making them easy to handle and install. Also, they have excellent insulation properties, which reduce energy consumption. PU foam core panels are cost-effective and improve the panel's structural integrity. However, these panels have a high fire risk. They are more prone to moisture damage if they are not properly sealed.

• Polystyrene (EPS) Foam Core Panels

  Expanded Polystyrene (EPS) foam core panels are popular for providing an economical choice. They are less expensive than PU panels, which makes them a preferred option for projects on a budget. EPS panels are lightweight and have good insulation properties. Plus, they are 100% recyclable, which improves their environmental appeal. But, they offer lower insulation and thermal efficiency than PU panels. Also, EPS panels have a higher density, which makes them more difficult to handle during construction.

• Polyisocyanurate (PIR) Foam Core Panels

  These foam core panels offer a good balance between insulation efficiency and fire resistance. They have a closed-cell structure, which improves their thermal stability. PIR panels have a lightweight design and high compressive strength. Additionally, they have a good insulation value and are eco-friendly. Nonetheless, they are more expensive than PU and EPS panels. Also, their insulation value is lower than that of the PU foam core panels.

• Honeycomb Core Composite Panels

  These panels use a cardboard honeycomb structure as the core material. This makes them lightweight and very stiff. Honeycomb core panels offer good sound absorption and are more environmentally friendly. However, they have low insulation properties compared to foam cores. Honeycomb core composite panels are also more susceptible to moisture and require careful handling.

• Polyethylene (PE) Foam Core Panels

  These panels are cost-effective solutions for projects requiring lower insulation values. They have a good resistance to chemicals and moisture. Also, they are very lightweight and easy to fabricate. Unfortunately, they have lower insulation efficiency compared to the other foam cores. Additionally, they have a lower structural integrity and stiffness.
