How to Read Specifications:

• B-very limited contribution to fire
• s1-little or no smoke generation d0-no droplets within 600 seconds 
• CE1-for structural applications

In addition to being B-s1-d0 certified, as required by the Technical Building Code, and CE1 structural certification, our product line is manufactured from a sustainably sourced, FSC® certified Baltic pine using the latest plywood manufacturing technology. Paged Softwood ThickPly FR is manufactured using complete immersion method in a sustainable fire retardant with no harmful compounds.

The standard PN-EN 13501-1+A1 is the Polish version of the European standard with the same number. It specifies the EU principles of classification with respect to reaction to fire for all construction products, including products placed within construction elements.

After acquiring a relevant fire resistance class based on the assessment of conducted tests and their results obtained in accordance with the standards effective in all EU Member States all construction products need to be marked properly on their labels.

7 basic classes

Pursuant to the standard applicable to construction products, there are 7 basic classes, i.e. A1, A2 ,B ,C ,D ,E ,F; however, in the case of floors, fire resistance classes are marked as A1fl, A2fl, Bfl, Cfl, Dfl, Efl, Ffl.

Specified in the standard PN-EN 13501-1+A1, the main fire resistance classes, i.e. A1, A2, B, C, D, E, F characterize a product with respect to the following criteria:

• the quantity and speed of energy emission during the combustion of a product,
• the time before a product ignites after contact with a burning object,
• the speed and range of the spread of flames.

• the basic class of a product is the most important; it specifies how (or whether) a product contributes to the development of a fire, i.e. how much energy a given product adds to the fire
• the safest fire resistance class is A1; it is followed by classes A2 and B. Products representing classes C-D-E and F may cause flashover or a sudden explosive spread of a fire characterized by a sudden temperature increase. Consequently, their applications should be limited as far as possible.
• the additional marking “s” placed next to the basic class as specified in the standard PN-EN 13501-1+A1 stands for “smoke”. Smoke is the cause of two thirds of all fire victims; therefore, it is a good idea to avoid all products generating intensive smoke, and marked as s2 or s3.

• the second additional marking “d” (drops) placed next to the basic class indicates the occurrence of burning drops and/or waste. The occurrence of burning drops or waste may cause the transfer of a fire to locations distant from its source.
