Structural Insulated Panels (SIPs)

SIPs are basically thick sheets of expanded polystyrene board sandwiched between two sheets of Oriented Strand Board (OSB) or plywood. They can be used to construct walls, roofs, floors — even basements. SIPs allow very little air to pass through them, so they create a super energy-efficient structure.

I'm not recommending one manufacturer over another, but Thermapan has several detailed videos illustrating SIPs and their advantages. For those with dial-up connections, they offer a free CD.
