evissa

Evissa delivers high-performance Structural Insulated Panels (SIPs) for energy-efficient, healthy buildings designed with comfort and well-being in mind.

Combining Passive House principles with innovative engineering, Evissa integrates design and construction in a collaborative, adaptable process that supports both creativity and precision. 

Each SIP features a Graphite Polystyrene (GPS) core between OSB facings, offering structural strength, airtightness (~1.5 ACH @ 50 Pa), and exceptional thermal performance. Panels are joined using OSB splines, timber studs, or I-joists. 

Working closely with architects and engineers, Evissa ensures project goals are met through modular SIP technology and smart, sustainable building solutions.
