Temperature classes
Temperature classes are existing from T080-T600.
The T300 means that Glasvezel composiet has a normal working
temperature, which is equal or lower than T300. |

Gas tightness classes
This means that according to a standardised test
the leakage rate in litres/seconds per square meters
of the flue surface area shall not exceed the values
given in the following table (before and after exposure
to heat). |

According to the gas tightness test of CSTB France
Glasvezel composiet has a leakage rate of 0,074 l*s-1*m-2 under the test pressure of 5000 Pa. According
to this H2 class can be accepted. |

|
| R6 |
|
Thermal resistance
Thermal resisitance is R= 0,06 m² K/W. The
R6 value is resulted from the multiplication of
R by hundred. The value of R is derived from the
thermal conductivity coefficient (1=0,4 w/m, K)
given by Kompozitor Ltd. |

Distance to combustible materials
The designation of distance of the outer surface
of the chimney to combustible material is given
in milimeters as: C = 50mm |
