As in all other traditional reinforced concrete building systems, prefabricated houses, pre-produced steel houses, pre-manufactured wooden houses; YapıPAN SIP Panels also include a manageable fire risk according to international standards. In the TSE and other countries' standards, the building materials used are generally required to form a flame barrier of 60 minutes in case the flame source is not removed and the classifications of the materials are made according to these criteria. The importance of 60 minutes is the assumption that fire-fighting teams can intervene in the fire during this time. It is foreseen that any loss of life will be prevented during this period.
The fire resistance of YapıPAN SIP panels depends on the materials used in their cores and shells.

1 - YapıPAN SIP-EPS Core Types as System: B1
1.a. YapıPAN SlP-EPS-OSB: B2 Nonflammability Class
1.b. YapıPAN SIP-EPS-EIB: B2 Nonflammability Class

3 - YapıPAN SlP-ROCKWOOL- Core Types as System: A1
3.a. YapıPAN SlP-ROCKWOOL-OSB: A2 Nonflammability Class
3.b. YapıPAN SlP-ROCKWOOL-FIB: A1 Nonflammability Class
3.c. YapıPAN SlP-ROCKWOOL-MgO: A1 Nonflammability Class

4 - YapıPAN SIP - COMBINED SYSTEM: As different materials are used, there are different properties.

OSB plates and YapıPOR brand EPS core used in YapıPAN SIP-EPS Core Panels are B2 flammability class materials. However, the whole system is classified as class B1. Fibercement sheets and rockwool show A1 class nonflammability. The meaning of B1 is that the material is treated as Fire Resistant material, which means that the flammable material is self-extinguishing within 4 seconds when the flame source is removed. The class A1 material is that the material does not deform, ignite or burn for 120 minutes. Tests are carried out according to DIN 4102 Part 1 or EN ISO 11 925-2 by accredited laboratories as well as in the whole world.
SIP Panels are fire resistant building materials. Because there is no air gap in the structure of the components that make up the SIP Panels and these components do not get oxygen into the walls during the fire, the fire cannot progress on the SIP Panel.

One of the most important features of the fire that should be known is; firstly curtains, furniture, wallpapers, books, etc. burn at the time of the fire. The majority of the deaths are due to the toxic smoke from the burning materials inside the house or the structural elements falling on the people. Because OSB plates used on the inner and outer surfaces of SIP Panels are not toxic materials and become charcoal in case of fire, they are pretty safe materials.
In case of Fibercement boards, the situation becomes even safer and shows a non-flammability of 120 minutes. But it should be known that, if a fire that has already begun to spread to the floor and / or to the roof, it is not important which material your structure is made of. Because the fire has reached a certain temperature and at the temperature which the fire reaches the material of the house (steel, concrete or wood) does not change anything. On the contrary, the houses made of steel are more dangerous because steel is a material that conducts heat well and steel collapses in cases of high of heat. You need to underline here; The statistics in the USA, Canada and Russia showed us that the people do not die of fires, but with the collapse of the heavy FLOORS, ROOFS, CARRYING STRUCTURES and because of their breathing of toxic gases.
