Evissa Pty Ltd
Design & Construct Company focused on Modular Technology and Passivhaus
Structural insulated panels (SIPs) are high performance building panels used in floors, walls, and roofs for residential and light commercial buildings. The panels are made by sandwiching a core of rigid foam insulation between two structural facings.
SIPs are manufactured under factory controlled conditions and can be used as a modular component and/or custom designed for each project.
Composition of Evissa SIPS consists of two typical Oriented Strand Board (OSB) panels, glued with a high-performance adhesive, on an Expanded Polystyrene (EPS) board.
Structural integrity of the building is achieved through the OSB skin. SIPs use less timber than typical framing. The panels are held together by OSB SPLINES / TIMBER STUDS / I-JOIST SPLINES / BOTTOM & TOP TIMBER PLATES.
Evissa SIPs can provide an airtight building envelope (~ 1.5 air changes per hour at 50 pascal pressure test, measured by a blower-door test) as well as meet the design needs of other highly energy-efficient buildings.
