Structural insulated panels are sandwiches of foam insulation between two sheets of fibreboard or plywood, and are used to build walls, roofs and floors in all kinds fo modern buildings. Instead of three components - a frame, insulation and sheathing - SIP panels are all three thing and come ready to install. SIP-constructed buildings are vastly more efficient, quicker to build, stronger, quieter and more draught-free than older post-war building systems. This illustrated manual takes the reader through the entire process of building a panel-constructed house, from planning and estimating, ordering, storage and handling to construction.
