Structural Insulated Panels (SIPs) are a versatile building material that can be effectively used in a variety of applications within a home. The correct answer highlights that SIPs can be utilized in floors, walls, and roofs.

SIPs consist of a rigid core of insulation, typically made from expanded polystyrene or extruded polystyrene, sandwiched between two structural facings, which can be made of oriented strand board (OSB) or other materials. This composition allows for excellent thermal performance, reducing energy costs and improving overall building efficiency.

In floors, SIPs provide a strong and lightweight alternative to traditional flooring systems, allowing for quicker installation and better insulation. When incorporated into walls, SIPs not only contribute to structural integrity but also minimize thermal bridging, enhancing energy efficiency. Similarly, when used in roofing systems, SIPs create an effective barrier that helps maintain stable indoor temperatures and reduce energy consumption.

Utilizing SIPs in multiple areas of a home underscores their flexibility and efficiency, making them a popular choice among builders looking for sustainable construction methods.
