Insulate Naturally

Summer heat protection compared to synthetic insulation. 
The Science doesn't lie.

​

It's all about low Thermal Diffusivity, Amplitude dampening & Phase shifting. 
Yes, it may sound a little technical and even a little boring, but the science doesn't lie

when it comes to the effectiveness of natural wood fibre insulation.

Amplitude dampening
 

​Amplitude dampening is a measurement of the difference between the fluctuations in the external and internal temperatures.  When the temperature fluctuates dramatically outside (for example, between 18 and 42 degrees = 24) and if the house can maintain a very low fluctuation in temperature (between 19 and 21 degrees = 3) then the building has been dampened from the external to internal side by 24/3 - a factor of 8.

 

Phase shifting
 

Phase shifting is the time span between the highest external temperature and the highest internal temperature. The aim of efficient summer heat protection is to delay the transfer of heat, until it cools down outside and the heat can be released back outside.  A phase shift of 10 hours is to be desired.  Wood fibre insulation achieves this by its density, low conductivity and thermal storage capacity.​
