YapıPAN SIP PANELS FIRE RESISTANCE


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.

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.

Contrary to the general belief, the resistance of OSB plate and wood is superior to concrete and steel. Fibercement plates are already cement based and therefore very resistant to fire. Today, in the United States, constructing the places, where large crowds gather together such as the indoor sports halls, from wooden carrier materials against the danger of fire is becoming more popular and in Germany where the standards are very high, steel carriers are covered with wooden materials are used for the same reason.


Researches on fires and compiled statistics clearly show that wood materials used as carriers are one of the safest materials.

The reason for starting the fire is never wood materials or their ignition characteristics. It does not mean that SIP Panels will be ignited easily because they are formed from an OSB plate, whereas the components inside the structure do not allow fire as you can see in the video above.
In the United States, according to the National Fire Prevention Association (NFPA), 3,300 people die every year from home fires and 700 of these deaths occur in children under 14 years of age. According to the same source, the reasons for house fires are listed as follows;


45% Kitchen and cooking
16% Heating equipment
8% arson
8% Electrical wiring and fuse boxes
5% Smoking
4% Clothes pressing and drying machines
3% Explosion
% 3 Candle
8% Unspecified and other reasons

Fire statistics in our country are not too far from this table. According to the statistics published by the Istanbul Fire Office, 40% of the fire incidents in Istanbul occurred in homes in 2015. In the case of house fires, sources such as electric contact, cigarette, intented, chimney and iron, and furnace stand out. As it is seen, knowing the reasons of the emergence of fires well is the first step of taking a wise approach to the fire problem and taking early measures.
Due to the non-permeability and carbonization properties, it can be precisely determined how long a building consisting of SIP Panels can withstand large fires, which helps us to take measures to control the risk of fire. SIP Panel structures can be designed and manufactured to withstand fire for 30-90 minutes. However, due to the high expansion coefficient of the steel, the bare steel structure can withstand even an ordinary fire for only 10 minutes, and the structure immediately collapses without giving any warning call.
Although the non-flammable materials that form the structural systems (such as reinforced concrete) are not flammable, the bearing properties of the structural steel (deformations) are reduced. The structural steel is very easily affected by thermal loads as a material that conducts heat well. Permanent deformations or deformations can occur on the nodes and cause transversal and uncalculated forces. The steel has already begun to lose its carrier properties at 200 ° C, losing 33% of its carriage at 350 ° C, 50% at 500 ° C and 80% at 700 ° C. The length of a steel element, which reaches 640 ° C, is approximately 1% longer. Therefore, the risk of collapse in conventional or prefabricated steel structures is higher. This means a danger to your life.

The following statement is taken from the website of Turkish Structural Steel Association. https: //www.tucsa.org/ en / celik_yapilar_yazi.aspx?

One of the weaknesses of steel is that it is very sensitive to heat. Steel is not flammable as a material, but its strength and elasticity decline as heat rises. In particular, when the temperature rises above 200 C, there are apparent strength values decreases observed (2).
This weakness of the steel structural systems against heat can only be solved by insulating the steel elements.


A similar situation applies to reinforced concrete structures. The fire in a structure can be up to 1093 ° C and generally does not exceed 815 ° C. The melting point of the steel is 1450 ° C. Thermal stresses in the event of fire and loss of carrying power, the steel comes to the critical point for static calculations at 550° C. If it exceeds this temperature, there will be a collapse by plastic deformations which will occur at the nodes. In fact, you can even test yourself about the behavior of wood and steel against fire. When you go to the picnic, take a piece of wood and an iron spoon and hold them both in your hand and try to keep them on the fire for a few minutes. Which material burns yor hands more quickly, the more heat is passing through it, and therefore the rapid response to heat will lead to rapid changes in the physical and chemical properties of the material.


One of the biggest advantages of SIP Panels in case of fire is the ability to change the part of a structure of a building that is affected at very low cost. After a small fire, most likely even stone walls will lose their technical characteristics. This also applies to reinforced concrete, steel or other prefabricated houses, and you will need to replace or replace the walls of your house by a new one after the fire has lost its technical characteristics. This will cost you quite a lot. In SIP Panels, it is very easy to replace the burning panels after a small fire with a new one, which is cheap. After all this information, we have a variety of applications for our customers who do not trust the fire performance of OSB plates, which is one of the safest carrier building materials with 95% wood and which is the safest against fire;


a) YapıPAN SlP Panel Covering the walls of your building with plasterboard: In the USA, Russia, Germany, Canada and other northern countries, the majority of the users of the SIP Panel (78%) with internal and external OSB coating cover the structures with plasterboard plates. This coating makes the OSB plate more resistant to fire, makes a positive contribution to sound insulation and provides more diversity for the ongoing fine workmanship. Plasterboard plate can be used on its own in the interior partition walls as YapıPAN SIP-Plasterboard board can also be used as additional protection and decoration material on the surface of YapıPAN SIP-OSB Panels.

b) YapıPAN SlP-MgO or YapıPAN SlP-Fibercement: We have already mentioned that there are many options that you can use on the outer surface of your SlP Panel instead of OSB. Nowadays, materials that can be used as building plates (plates) are multiplied and their characteristics vary according to the place to be used.
