Prefabricated self-supporting panels, structural insulated panels, panelized building system or structural insulated sandwich panels are all formulations to define the same type of building material - SIP panels.<\/p>\n

When I wrote about the different types of wooden houses<\/a> a reader brought to my attention that there is another type of house I haven't mentioned. This is prefabricated panel construction, i.e. SIP panels, which is different from prefabricated structures<\/a> which we mentioned in our articles. The prefabricated structures are made in a \"house factory\", which reduces the working time on site. Walls are made on a project-by-project basis, varying from house to house. SIP panels are a factory-built building material like other wood-based panels<\/a> and used by construction companies to erect houses.<\/p>\n

SIP are structural insulated panels<\/h5>\n

SIP stands for the English name of the material - Structural Insulated Panels<\/strong><\/em> - and stands for structural insulated panels. These are sandwich panels that have an insulating material between two structural panels.<\/p>\n

The tiles are mostly made of OSB<\/a> construction, but can also be made of metal, plywood, fiberglass, cement or magnesium oxide. Insulation is the core of the panel and can be expanded polystyrene, extruded polystyrene or rigid polyurethane foam. Other core options are available but are less commonly used.<\/p>\n

Panels can be used to build interior and exterior walls, floors and foundation elements or roofs. They are built to suit any type of building project. The walls are also made to be assembled using similar panels that also contain insulation. This makes the building energy efficient and eliminates the possibility of energy bridging.<\/p>\n

Systems have also been developed that allow panels to be produced on site. This further reduces working time. However, the panels produced in the factory have better properties and the quality is the same for all batches.<\/p>\n

Based on the idea of insulation inside the panel, eco-friendly panels have also been built, where pressed straw bales are used as insulation between two plywood panels. These systems are used to build \"green\", ecological and energy-efficient houses.<\/p>\n

A bit of history<\/h5>\n

The term SIP was introduced in 1935 by the Forest Products Laboratory Madison, USA for panels consisting of a wooden frame with plywood and cardboard on either side and insulation on the inside. These panels were used to build houses that were dismantled after 30 years and analyzed for strength and warping over time.<\/p>\n

Their appearance was necessary because, with an increased demand for housing and the need for sawn timber, less wood was used to build a house. In addition, the system allowed for quick and economical construction, thus lowering the price of houses.<\/p>\n

In 1952 Alden B. Dow made the first SIP panel using foam insulation. The panel went into mass production in the 60s. Such prefabricated panels were used extensively in the USA for house construction before reaching Europe, where the method was later adopted.<\/p>\n

Advantages of SIP panels<\/h5>\n

Panels are presented by many manufacturers and builders as the building material of the 21st century. They believe that the use of SIP panels for building houses or industrial structures comes with advantages for architects, designers and builders as well as for the beneficiaries.<\/p>\n

Let's start by looking at some of the qualities of the panels:<\/p>\n
