Team members from Shirey Contracting, an Issaquah-based remodeler and builder, work on installing a pre-fabricated structurally insulated panel at a residential remodel project outside Seattle, thus framing out a large picture window.  SIP's laminate a 6-8" thick layer of strofoam between two OSB boards in pre-made shapes, thus combining framing, sheathing, and insulating into a single step.
