Structural Insulated Panels (SIPs) are panels that are used to build the walls of a house. They are made up of two layers of metal or wood paneling with a layer of insulation in between. The insulation helps to keep the house warm in the winter and cool in the summer, which makes it much more energy efficient than other types of construction. SIPs are also much quicker to build a house with than traditional construction methods. They are a great solution when building an energy-efficient and cost-effective home.
