Aerogel Thermoreflective Paint

Today, Ama Nanotech extends its range of Building & Construction solutions with the THERMOGEL PAINT line of thermoreflective paints containing Aerogel and other precious nanotechnological components, without glass or ceramic microspheres.

Formulated using advanced technologies, thermoreflective paints avoid the dispersion of energy through walls, drastically reducing thermal bridges and preventing the growth of mould without using chemical additives.

By using this type of paint with a double function – both as a surface finish and to enhance energy-saving properties – building shells become elements that play an active part in limiting the energy consumption of the entire building, with the added advantage of significant reductions in application times, with the consequence of even further savings.

In addition to guaranteeing longer duration (for example on wall coatings) on the surfaces to which they are applied, these special polymer-based paints with special additives reduce the temperatures of these surfaces both externally and internally, permitting energy savings in building climate control, a strategic element in policies for the limitation of energy consumption in a country like Italy characterized by summers that get hotter every year.

Reducing interior building temperatures by just one degree means reducing energy consumption by 8 -10%, avoiding the emission into the atmosphere of 470 kg of CO2 every year.

When THERMOGEL PAINT products are applied either internally or externally, the reflection of thermal radiation prevents the supporting structures from heating up, and the resistance to heat transfer is at least four times higher than for conventional paint products, ensuring that heat is not transmitted towards building interiors in summer. With these supporting structures that are not heated up from the outside, the coolness is also distributed evenly inside the building. In winter instead, the warmth generated by the heating system remains trapped inside the building for longer. Because they reflect both light and heat, THERMOGEL PAINT products can be used on all surfaces through which high temperatures and solar radiation can be channelled into the building shell. This means that they can be applied not only on flat surfaces, but also on old bitumen roofing felt, exterior walls, prefabricated concrete components, plastic and glass elements and interior walls.

In addition to the basic requirements for paint products – protection and decoration – another crucial factor is ENERGETIC EFFICIENCY, aiming to achieve significant energy savings that also have important environmental impact effects.

Technical properties of the THERMOGEL PAINT range

    (Thermogel OUTSIDE ASTM C1549-09) – Thermal emissivity E = 0.89
    (Thermogel OUTSIDE EN15976) – Solar reflex index SRI = 108
    (Thermogel OUTSIDE ASTM E1980-11) – Permeability to water vapour
    (Thermogel OUTSIDE Sd = 0.10 – EN 7783-2 standard)
  • Maximum water repellence
    (Thermogel OUTSIDE W24 = 0.020 – Norma EN 1062-3)
    (Thermogel METAL EELAB ETR 16-0061 certificate)
  • Solar reflectance R = 86
    (Thermogel METAL ASTM C1549-09)
  • Thermal emissivity E = 0.91
    (Thermogel METAL EN15976)
  • Solar reflex index SRI = 109
    (Thermogel METAL ASTM E1980-11)
  • Low content of VOCs
  • Active protection of surfaces
  • Excellent anti-mould properties
  • Excellent antibacterial properties
    (indoor air quality)
  • Excellent anti-static properties


  • there is no energy dispersion through walls
  • interior living comfort and wellness are improved
  • an insulation barrier effect is created
  • no condensation on walls because there are fewer thermal bridges
  • support surfaces are permeable but water-repellent
  • humidity levels in treated spaces remain stable, preventing the growth of spores, mould and germs
  • lower microcirculation of dust in interior spaces due to reduced air convection currents, helping to improve conditions of wellbeing and reducing the possibility of allergic reactions


Without Thermogel Paint, the thermal radiation of the sun is transmitted into the building in summer, heating the internal spaces, and living comfort can be guaranteed only by using air-conditioning systems.

The application of Thermogel Paint allows the solar radiation falling on the building to be reflected, keeping the interior temperature cooler and promoting energy savings. In winter, the warmth generated by the heating system also remains inside the building for longer.
