For AeroTherm to perform at its optimum efficiency, only a 1mm coating is required to the internal surfaces. 

This plaster like coating cleverly combines advanced materials to enable the maximum efficiency of any heat created in the room. The thin depth of the coating allows the AeroTherm to focus on reflecting the heat within the room and not let it escape into the building structure. 

The two key materials that help AeroTherm to perform are Aerogel and glass microspheres. The Aerogel component has been nicknamed ‘frozen smoke’ or ‘solid air’ due to way in which the liquid element of the gel has been extracted out, leaving only a complex solid-matrix behind which is almost weightless. This nano-structure framework creates a large internal surface area which is able to disperse heat across the material and so restrict conductive and convective heat transfer through the material. Aerogel does not however prevent radiant heat passing through it but this actually helps the hollow glass microspheres in the AeroTherm to capture any infrared radiation and refract and reflect the energy waves freely back into the room.

This advanced process of absorbing, reflecting and emitting heat allows AeroTherm to quickly balance the transfer between any heat sources in the room and the room’s surfaces. The ultra-thin layer essentially becomes a thermo reactive coating that continually works to minimise any hot to cold movement. The impact of this is a lower heat energy requirement to maintain a comfortable room temperature, which minimises cold spots and creates wall to wall “thermal comfort” for the occupants.

A further benefit of creating warm walls is a much reduced risk of condensation forming on the surfaces, which leads to mould growth.

AeroTherm has been carefully designed to combine advanced materials such as aerogel and hollow glass microspheres.

A specially formed binder enables the materials to work together in a plaster for internal walls and ceilings.



Aerogel is the most advanced and effective insulant ever created. So good is its ability to prevent heat transfer in a lightweight material, that NASA used it extensively throughout their space program.



AeroTherm is filled with tiny hollow glass bubbles, which are only microns in diameter. These are dispersed through the AeroTherm to refract and reflect the radiant energy.
