At B6 Gruppen, we offer several types of materials, all of which have good thermal insulation properties.
Common to our materials is that they are all of polymeric origin - and thus have a range of advantage compared to the traditional undesirable mineral wool.
The SI unit for thermal conductivity is "Watts per meter Kelvin" and expressed as follows: (W/mK) ie. Watt per meter, per degree temperature difference between the two temperatures, this is also known as λ-value (lambda value).
Note: The less λ-value, the better the insulation.
By comparison, mineral wool has a thermal conductivity of about 0.036 W/mK - which polymeric materials with ease can compete with.
Values for typically used polymere materials:
- EPS foam: 0,031 - 0,034 w/mk
- PE foam: 0,034 - 0,037 w/mK
- PUR foam (flexible) : 0,034 - 0,036 w/mK
- PIR & PUR foam (rigid) : 0,021 - 0,025 w/mK
