The owner of the declaration is liable for the underlying information and evidence.

Product Group and Name Architectural and Insulated Precast Panels (UN CPC 3755)

Product Definition Architectural precast panel - a single-wythe exterior wall panel and/or architectural trim product.

Insulated Precast Panel - two conventionally reinforced or prestressed concrete wythes with a continuous layer of rigid insulation placed between.

Architectural and Insulated Precast Panels are engineered construction products produced by casting concrete in a reusable mold or "form" which is then cured in a controlled environment, transported to the construction site and lifted into place.
