Lambda performance of Glasswool

Lambda values allways have to be compared at the same temperature
In Europe values are measured and declared at 10 C
In the US at 24 C , in Japan at 25 C ...

Lambda, R - value, U - value
Material constant: insulating capacity
Lambda: W/m. K The lower the better
Application parameter R
Thermal resistivity, R = d/ (m2. K/W) d = thickness of insulating product
U The
rmal transmittance U = 1/R (W/m 2. K)

U- value calculation for building facade
U0 = ((U w x A w) + (U f x A f) + (U d x A d )) / A t
U = component U value A = surface, m 2 w = wall f = fenestration d = doors t = total

2. Acoustics
Too much noise outside the building entering the space
Too much noise from adjacent spaces
Too much noise generated within a specific space
-
Sound level vs. Sound frequency
-
Different acoustic attenuation mechanisms
1 sound absorption
2 sound transmission - spring-
3 sound impact
-
a) Sound absorption - air flow resistivity

P2 (Pa) r (kPa.s/m )
Mineral wool, in contrast to foams, is a porous medium, capable of attenuating air pressure (sound). Influencing parameters are: fibre fineness, fibre orientation
and density. The best result is obtained with an air flow resistivity r between 5 and 10 kPa.s/m 2.
