The Science Behind Thermal Wall Panels and Their Impact on Passive
House Performance
Thermal Insulation Properties

Thermal wall panels are engineered with advanced materials and construction techniques to provide exceptional
insulation properties. These panels typically consist of a core material with high thermal resistance, such as expanded
polystyrene (EPS), extruded polystyrene (XPS), or polyurethane foam, sandwiched between two layers of structural
sheathing. The core material's cellular structure traps air, creating a barrier that significantly reduces heat transfer
through conduction. This results in a high R-value, which measures the panel's thermal resistance. The superior
insulation properties of thermal wall panels contribute to maintaining stable indoor temperatures, reducing the need for
active heating and cooling systems in passive house design.

Airtightness and Moisture Control

One of the key requirements in passive house design is achieving a high level of airtightness to prevent uncontrolled air
leakage and associated energy losses. Thermal wall panels excel in this aspect by providing a continuous, sealed
envelope around the building. The panels are designed with interlocking joints and specialized sealing systems that
