10 things you didn’t know about ISOBOOSTER

A great deal of care, attention and research has gone into the development and optimisation of ISOBOOSTER, striving to create optimum-performance insulation. The development of ISOBOOSTER is founded on age-old knowledge and basic physical principles. We are proud to make these accessible and applicable through our product, and happy to tell everyone about them. So here are: “10 things you didn’t know about ISOBOOSTER”.


10 things -1


The capillary action in stone draws water upwards through the stone. This leads to damp walls, corners, crawl spaces, basements, etc. Stone walls start acting like a sponge at a relative humidity of 75%. It has been established in situ that the relative humidity in cavities or crawl spaces with aluminium reflection does not exceed 62%. Read more about “Using Isobooster to make your home damp-free”.

Two Amsterdam physicists have researched how it is possible that water (the water molecule) falls apart (evaporates). They ’fired’ infrared light pulses with a wavelength of around 3000 nanometres at liquid water. (Thermal infrared). This wavelength corresponds to a frequency of 1014 Hertz, equal to the vibrational frequency of the hydrogen atoms in the water molecule. They studied the vibrating atoms and saw that this additional vibration energy weakened and eventually broke the bond between the hydrogen and oxygen atoms, thus making the water molecule ‘fall apart’.

As long as the vapour is allowed to escape, the air that remains is dry. Dry air insulates twice as well as humid air, leads to a healthier living environment and helps to prevent mould. Read more on “How does Isobooster work?”



Materials that contain less moisture conduct less heat. Empirical research has shown that molecules in stone, concrete and wood conduct heat slowly and even store it, improving the lambda value by a factor of 10. Stone, plaster and wood are excellent heat storage batteries (even 1770x better than air) and subsequently pass that heat on or give it back it in the form of radiant heat.



In the early 20th century, physicist Henri Coandă discovered that hot, rising air always moves upwards along surfaces (e.g. cold outer walls): The Coandă effect. The Coandă effect, also known as the ceiling effect, is the mechanism whereby air flowing along the wall creates low pressure, making the rising air stick to the wall. A continuous airflow develops, and Isobooster then reflects the heat. More information: “Isobooster and the Coandă effect“.



Isobooster insulation foil reflects the heat radiation, sending it back into the room at almost the same intensity, simply reusing the heat that would otherwise have been lost. 



Although still relatively unknown, the way metals behave when confronted with heat rays has been known for a long time. Indeed, one of the first articles recommending aluminium as an insulation material dates back to 1910.  If you would like to see an example of this, please click here to read an article from 1950 with a developed application.

It is common knowledge that if materials contain 1% less moisture, they conduct 10% less heat. It has been demonstrated in situ that molecules in stone, concrete and wood conduct heat slowly and even store it, improving the lambda value by a factor of 10.

Humans, with an average body temperature of 37°C, only emit ‘far infrared’ radiation (equivalent to approx. 100 Watt). Read more about “Infrared heat insulation


Want to try before you buy? Experience the effect of reflected infrared radiation yourself by holding a piece of aluminium foil close to your face. You will soon find yourself breaking out in a sweat!

Polyethylene, the basic material of our insulation foil, is very strong and resistant to caustic substances and damage. This makes Isobooster highly durable, offering you years of cost-saving comfort. Tests (by the Netherlands Organisation for Applied Scientific Research, TNO) have shown that Isobooster can last as long as 70 years! Click here for more benefits of Isobooster.
