The word SIP, is formed by the initials of the words “Structural Insulated Panel”.
YapıpanSIP Panel is a type of sandwich panel that contains generally folllowing structures on its outer and interior surfaces as carriers: Oriented Strand Board (OSB) plate, Fibercement, Magnesium Oxide Plate (MgO), Scaleboard, Plywood and in the middle of them Expanded Polystyrene Foam (EPF) that is formed from styrofoam or rockwool. These materials have features to carry high amounts of loads and it is a high performance Sandwich Panel  / House / Preformed Wall / Prefabricated Structure System which is used as main material of inner-outer walls of buildings, roof and covering material, isolation material of roofs and outer walls, roof furnishing material as a structural member, main material in residence buildings, main material in prefabricated buildings, main material of vineyard houses and material of many other structures. 

Plates forming the surface (shell) of the Yapıpan SIP Panels are the structural carrier members of the panels and EPS or rock wool in the core is produced for isolation and load transfer.

Plates on inner and outer surfaces (shells) and EPS (Styrofoam) in the center are bonded to each other by applying high pressure and using very powerful Euro-polyurethane adhesives. YapıPAN SIP panels are used as walls, floors and roof panels in housing and other structures. In this way, structure gains Monobloc property and this provides an important advantage in case of an earthquake. Structural properties of SIP panels make them act like a NPI profiled steel. While insulation core between inner and outer surfaces make panels on the surfaces work together as a monolith and show resistance against rupture, panels on the surfaces are resistant to compression and tension forces.

Upon request or according to needs of projects, materials in a wide range such as Fiber Cement Plate, MgO Plate, cement board, sheetrock, green board can be used instead of OSB plates. Each of these plates has their own technical specifications. So we will appreciate to make suggestions according to the needs of your project.

Invention of SIP panel dates back to 1930’s however their first use in buildings took place in 1952 in US. Until now, hundreds of thousands of houses were built by using SIP panels in United States, Canada, Russia, Germany, Finland, Ukraine, Norway and many other northern countries and keep going to be used with an increasing rate. SIP Panel technology is exported to world from countries like United States, Finland and Canada which are aware of ecological ethics. During the 60 years from invention of SIP panels to present, they were processed even into their smallest details, examined by scientists in many research areas, eluded many natural disasters. There are regulations, laws and established associations about them. In brief, SIP panel technology is a highly safe and efficient system used by many western and northern countries for years. In some countries they are known as “Canadian Type Houses”.

Today no technology provides the advantages that SIP panels provide such as;
-harmless to health
-high heat efficiency
-fire resistant
-fast setup
-customer friendly
-worker friendly
-nature friendly
-economic friendly
-resistant to earthquake
-resistant to wind
-wide design opportunities

That is why SIP panel is a revolution in the area of PANEL/HOUSE/WALL/STRUCTURE technology and used by hundreds of thousands of people. Our today World of having high heat and energy costs, SIP panel technology is the only way to be used in peace and trust.



OSB plate used in SIP PANEL systems emerged as a requirement after result of the works carried out by a private company in 1930 in Wisconsin, USA in order to protect wood and forest products as well as to provide energy efficiency. The first SIP PANEL home in history was made in the USA in the 1950s. Since then, the use of this system, which is widespread in northern countries, is unfortunately not known enough in our country.

Increasing energy costs are increasing the costs of heating and cooling. This increases the interest of SIP Panel houses every day.
In the US, Russia and Canada, the use and awareness of SIP PANEL is quite high.

In these countries, it is a legal obligation to design special architectural and static projects for SIP PANELs. Its audit and approval is made by experienced and certified organizations.

SIP PANEL manufacturers have a union in the United States. There are also dozens of non-member producers who produce SIP Panels.

Today, hundreds of thousands of houses, homes, factories, poultry farms, schools, state buildings, police stations, multi-storey buildings, and hundreds of such buildings in the USA, Canada, Russia, and many other northern countries are producd from SIP PANELS in a FAST, ECONOMIC, EASY and SAFE way.

According to SIPA data, 2.000.000 m2 SIP Panel is produced annually in America. This figure is increasing by about 5% each year due to the peoples interest in the SIP Panel.

Of these SIP panels or structures, only 57.8% were built for housing, 41% for commercial use, and 0.9% for non-building use.

The most preferred SIP Panel type in the US is the OSB-faced SIP Panel with 85%. This rate is higher in Russia. 95% of the SIP Panels produced in Russia are produced from OSB3 plates.

The US has made many significant progresses in conserving energy in residential and other buildings. Research on this subject has been encouraged. The Housing department of the Office of Science & Technology (PATH) thought that the energy used in housing could be reduced by 50% in 2010, and this could only be achieved with SIP Panels. According to PATH, SIP Panels are the technologies of the future.
