Made with insulation at its core, EXPOL Emperor Panel offers superior performance in standalone buildings. Traditionally used for specialised areas such as sterile or climate-controlled zones. It offers amazing efficiency in additional living spaces such as our range of Simple Spaces and Living Spaces.

Emperor panel comprises outer skins of 0.59BMT pre-painted COLORSTEEL produced by NZ Steel, with a core of CFC-free expanded polystyrene foam containing flame retardant.


Building with EXPOL Emperor Panel offers several advantages when compared to traditional construction methods.

Energy Efficiency: EXPOL Emperor Panel is highly energy-efficient due to it’s insulation properties. The panels consist of a polystyrene foam core sandwiched between two rigid sheathing materials, in the case of EXPOL Emperor Panel, ColorSteel. As a result, EXPOL Emperor Panel provide excellent insulation and can significantly reduce heating and cooling costs.

Improved Indoor Air Quality: The airtight construction of EXPOL Emperor Panel helps prevent drafts and infiltration of outdoor pollutants, ensuring better indoor air quality. This can be particularly beneficial for individuals with allergies or respiratory conditions. Additionally, the panels insulation properties contribute to consistent indoor temperatures and reduced condensation, which can help prevent mold and moisture-related issues.

Reduced Thermal Bridging: EXPOL Emperor Panel creates a continuous layer of insulation, reducing thermal bridging and preventing air leaks. 

Noise Reduction: EXPOL Emperor Panel provides excellent sound insulation properties, creating a quieter indoor environment. The polystyrene foam core helps dampen sound transmission, reducing noise from outside sources and between different areas within the building.

Strength and Structural Integrity: EXPOL Emperor Panel offers exceptional structural strength. The combination of the polystyrene foam core and ColourSteel skins creates a rigid, load-bearing structure. Additionally, the panels distribute weight evenly, reducing the risk of structural issues over time.

Faster Construction: Using EXPOL Emperor Panel can speed up the construction process when compared to traditional methods. The panels are prefabricated off-site according to precise measurements, ensuring a high level of accuracy and reducing waste. The quick assembly of panels can shorten the overall construction time, allowing you to move into your new Space sooner.

Sustainability: EXPOL Emperor Panel is an environmentally friendly building material. The manufacturing process typically uses less energy compared to traditional construction materials, and the insulation properties contribute to reduced energy consumption throughout the building’s lifetime. Additionally, the panels are made from renewable and recyclable materials, making them a sustainable choice for construction.

Design Flexibility: EXPOL Emperor Panel offers design flexibility, allowing for a wide range of architectural styles and layouts. The panels can be easily customized and cut to fit specific designs and dimensions. Whether you’re building a residential home, commercial building, or other structures, EXPOL Emperor Panel can accommodate various architectural requirements.

EXPOL Emperor Panel contains recycled content and can be easily recycled.
