2 For testing from submitted samples of thermo insulating material in the laboratory was cut six samples dimensions 30x30 cm, different thicknesses, on which is checked coefficient thermal conductivity. The tests were conducted in accordance with BAS EN 12667/2005 on the device LM.305 lambdametar, manufacturers STIROLAB d.o.o. Slovenia. Test results are given in the table 2. Table 2.

Testing the reaction to fire Flaability of product exposed to a direct flame effect - Part 2 : Flame testing from one source, flat method EN ISO By accidental method it was taken six samples dimension 250 x 90 in accordance with EN ISO , three sample is expected by width, a three sample by length insulation plates of wool. There was no deviation of the test method, samples are conditioned rooms at a temperature (25±5) o C and relative humidity (50± 20)% in period 28 days. T h e f l a m e w a s a p p l i e d f o r a d u r a t i o n o f 30 seconds. Occasionally testing reaction to the fire, the flame did not reach 150 above the point application of flame, there was no ignition filter paper, as well as the drip flaable parts tes t sample. The sample showed if it is flaable but self - contained by creating protective black layer which is invincible.

9 IV. CONCLUSION Based on conducted tests, it has been established that sample thermal insulation material from wool ovations, dimension 300x300, thick 30 has a medium value of thermal conductivity λ= 0,03148 W/mK, and resistance to heat passage R= 0,95 m 2 K/W. For sample thermal insulation material from wool ovations, dimension 300x300, thick 80, medium value thermal conductivity amount λ= 0,03879 W/mK, and resistance to heat passage R=2,06 m 2 K/W. For sample thermal insulation material from wool ovations, dimension 300x300, thick 80, medium value thermal conductivity amount λ= 0,04053 W/mK, and resistance to heat passage R=2,46 m 2 K/W. The examined material falls into category D according to EN ISO An integral part of the report No /17 of year is Conclusion. The results shown relate exclusively on tested samples.
