Type 2: Insulated Sandwich Panel

At Entec, we offer a range of prefabricated plant room construction styles to suit different project needs. Our Insulated Sandwich Panel rooms are a popular choice for clients who need a fast, cost-effective solution without compromising on performance or compliance.

These rooms are ideal for housing electrical equipment in a clean, thermally efficient, and weatherproof environment. Whether it’s a pump station, control room, or switchboard enclosure, our sandwich panel rooms are designed to meet your operational requirements and site conditions.

An insulated sandwich panel room is built using composite wall and roof panels made up of two steel sheets bonded to a rigid insulation core. These panels are lightweight, strong, and thermally efficient, making them ideal for prefabricated buildings.

Depending on the room’s design requirements, the panels are either mounted on an internal support structure, or are constructed without a structure, with the wall and roof panels themselves providing the building’s strength.

Key benefits include:
