Introduction
A structural insulated panel, or structural insulating panel, (SIP), is a form of sandwich panel used in the construction industry.
SIP is a sandwich structured composite, consisting of an insulating layer of rigid core sandwiched between two layers of structural board, used as a building material. The board can be sheet metal, plywood, cement, magnesium oxide board (MgO) or oriented strand board (OSB), and the core can either be expanded polystyrene foam (EPS), extruded polystyrene foam (XPS), polyisocyanurate foam, polyurethane foam, or be composite honeycomb (HSC).
SIPs share the same structural properties as an I-beam or I-column. The rigid insulation core of the SIP acts as a web, while the sheathing fulfills the function of the flanges. SIPs combine several components of conventional building, such as studs and joists, insulation, vapor barrier and air barrier. They can be used for many different applications, such as exterior wall, roof, floor and foundation systems.
Challenges
Approaches
Use Titebond II, upcycled fabric scraps, hemp, lime, sand, pozzolans, to create hempcrete fiber coated panels.
This results in a waterproof, insulating, rigid panel which resists mildew and mold and is made almost entirely from the waste stream.
