Anyone heard of Innovida composite sip? Seems like they are similar to Durasip. Came across them in looking at affordable earthquake proof homes for Haiti.

InnoVida's Fiber-Composite panels are made of a
polyurethane insulation foam core that is sandwiched between two
composite structural skins bonded together with InnoVidaResin™.
Once
the panels are bonded together, with InnoVidaBond™, they are seamless.
The closed foam core becomes a monolithic structure that reduces air
leakage and thermal bridging through the panels by providing a
continuous span of structural and insulating material. The structure
also becomes 100 percent waterproof, much like the hull of a boat.
InnoVidaPanels™
make stronger, more energy efficient, cost effective homes and
buildings. The superior insulation significantly reduces the amount of
energy needed to heat and/or cool the structure and provides excellent
noise reduction.
Used for walls, roofs, floors and foundations,
InnoVidaPanels™ can be used to build homes, schools, commercial
buildings, warehouses - or any type of structure normally built using
traditional construction methods and materials. In addition, due to the
properties of the components, InnoVida can also produce floating
platforms for any type of structure.
InnoVidaPanels™ begin life
in one of our factories. The panels are manufactured and then cut by
special machinery to the specific measurements of the structure to be
built. Our panels can be curved into any shape and, like any other
structural material, can be covered with any desired finish (stone,
stucco, siding, wallpaper, etc.).
