Liquid Window Insulation

Windows account for 30-50% of all energy waste in air conditioned buildings.  Liquid Nanotint is a clear insulative coating that blocks up to 98% of infrared heat and 99.9% of UV for glass and plastics.

  • Better than plastic films.  Lasts longer.  Won’t peel, crack, chip or bubble.
  • Warm in winter.  Cool in summer.
  • Better payback and lower lifecycle cost.
  • USGBC LEED credits.
  • 10% tint is bluish for color enhancement and glare reduction.


Liquid Nanotint™ is a spectrally selective thermal insulation coating ideal for single-pane glass and polycarbonate surfaces. Applied like a paint, Liquid Nanotint is capable of blocking 100% of Ultraviolet (UV) rays and up to 98% of Infrared (IR) heat while maintaining up to 84% Visible Light Transmission (VLT).*  Through the combination of solvent borne metal-oxide nano-particles and an inorganic adhesive binder, Liquid NanoTint forms a 10 micron thick self-leveling clear coat that bonds directly to glass and polycarbonate surfaces.

Unlike conventional window films, Liquid NanoTint will not peel, crack, bubble or fade over time lasting a minimum of 10 years**. In addition, NanoTint can be applied to bent glass, historic building windows, skylights and textured glass surfaces.  With the ability to mitigate both radiant and partial conductive heat, Liquid Nanotint can effectively keep indoor environments cooler in summer and prevent heat loss in the winter all while allowing you to benefit from the natural daylight gain.

NanoTint is professionally applied with a paint roller** which makes it the ideal choice for retrofitting existing inefficient single-pane glass buildings without having to spend money on costly replacement “energy efficient” window assemblies.  In the United States alone, up to 40% of all buildings are comprised of un-insulated single-pane windows. Billions of square feet of windows are responsible for over 25% of the heat transfer in structures – Liquid Nanotint presents a non-invasive, cost effective alternative to dark window film or costly replacement windows while delivering year round energy savings in any type of climate.

* Results may vary depending on the type and opacity of glass being coated.
** Application recommended by certified installers on interior surfaces.  Sample kits available on limited basis for certifying technicians only.  Not for DIY or consumers.

Comparison Chart:

How to read the chart above:

  • Tint.  The opacity or percentage of natural (visible) daylight being blocked.  The lower the percentage the better, unless your goal is to darken the space. Keep in mind, dark plastic films tend to be reflective at night, blocking the view out at night.
  • Visible light Transmission is directly related to tint.  The higher the percentage the better.
  • UV rejection is the % of damaging UltraViolet rays being blocked.  The higher the percentage the better.
  • IR rejection is the % of infrared heat from the sun being blocked.  For warmer climates that need cooling, the higher the percentage better.
  • SHGC is the % of solar heat entering the space. For warmer climates that need cooling, the lower the percentage better.
  • LSG is the ratio of Visible Light Transmission over Solar Heat Gain (VT/SHGC) which measure overall efficiency of a window or skylight coating.  The higher the percentage the better.

The Solar Heat Gain Coefficient (solar efficiency) of new (dual pane low-e) assemblies ranges from 0.41 – 0.60.  However, with daily thermal and UV aging, the soft rubber seals harden and decay, allowing the inert gas between the panes to leak out.  As a result, the thermal efficiency is reduced, leaving the SHGC higher (less efficient) than the even the single pane NanoTint coated alternative.

This is a summary of installation process.  Important.  The detailed installation instructions must be strictly followed.  Warranty is ONLY available if installed by certified technicians on interior surface.

Step 1.  Mask off areas to be protected.

Step 2.  Clean and dry surface carefully using cleaner/degreaser compound.  Test to make sure surface is completely hydrophylic (water sheets off) before drying with lint free wipes and applying LNT coating.

Step 3. Prime surface using lint free cloth.  Wipe on using squeegee and lint free cloth.  Do not use circular motions.

Step 4. Mix hardener and base by weight and roll on using select high density foam rollers.  Roll on following instructions.  Sprayer may be used on some opaque surfaces, like skylights, not requiring perfect visual clarity.

  • Dry time: 2 minutes.  Tack free in 30 minutes.  Odor free in 4 hours.  Full dry in 24 hours.
  • Cure time:  Safe for routine cleaning in 14 days.
