sandwich panels

Sandwich panels are building materials composed of three layers: two outer sheets (often metal or other durable materials) and a lightweight core in between. The core provides insulation and structural support, while the outer layers protect and give strength. This design makes sandwich panels excellent for quickly constructing walls, roofs, and facades that are strong, insulated, and easy to install. They are widely used in industries like construction, transportation, and refrigeration because of their efficiency, lightweight nature, and thermal performance.
