Polyethylene (PE) foam is a lightweight, closed-cell material widely used in construction for thermal insulation, moisture barriers, and expansion joint fillers.

Key Applications in Building

1. Thermal Insulation: Regulates indoor temperatures in roofs, walls, and metal pre-engineered steel buildings (PEB) to lower cooling energy use.
2. Moisture & Vapor Barriers: Blocks water, condensation, and dampness from entering concrete or walls.
3. Joint Sealants & Fillers: Acts as backing rod material or expansion joint fillers to absorb structural shifting and prevent leaks.
4. Acoustic Dampening: Reduces sound transmission between floors and interior walls.
