The economically and ecologically smart choicee


Keep the heat on the right side of the glass

SketchThermo is a powerful liquid thermal barrier that is applied to windows.

Its role is to block 99% of ultraviolet (UV) and 85% of infrared (IR) rays and let all of natural light pass through your windows.

Energy efficient, SketchThermo drastically reduces heat transfer between the exterior and interior of the building while allowing natural light to pass through.

This reduction results in:

  • an indoor temperature 3°C to 5°C cooler in summer
  • a drastically reduction in heat loss in winter.

Benefits for you:

  • A cooler temperature in summer means a less expensive building to air-condition.
  • Less heat loss in winter means lower heating costs.
  • It is also a better distribution of the ambient temperature and more comfort for the occupants!
  • Don’t replace your windows with our coating that turns panes into energy-efficient glass

The guarantee of the application covers the performances described on the technical data sheets, for the periods and exclusions of each treatment indicated below. The limited warranty is conditional on the treatments being applied by certified Sketch Nanotechnologies technicians.

The warranty is transferable. The 10 year period does not reflect the duration of the product, but rather the time that our technicians can rectify if the claim conditions apply.

The warranty excludes any liability related to non-compliance with maintenance instructions, replacement or breakage of the thermo, normal phenomena of expansion and retraction caused by hot and cold.

The thermos can still loosen, become foggy and show signs of degradation like any other thermos that has not been subjected to SketchThermo.

The normal aging of your thermo will not constitute a reason for claiming the SketchThermo product warranty.
