Presented by Larry J. Eichel, Sustainability Directory, February 5, 2019 1:00p.m. Insulating Glass Manufacturers Alliance (IGMA) Winter Conference
Nanotechnology has been growing exponentially since the late 1990s and early 2000s, this movement has expanded into a variety of built environment applications. Silver low-emissivity (low-e) coatings have been used to make windows more energy efficient while maintaining high transmittance since the late 1980s. Energy efficiency is of the utmost importance in today’s built environment as energy prices and demand continue to increase while natural resources dwindle and extreme weather incidents increase in frequency and severity. New breakthroughs in nanotechnology offer the aggressive solar heat gain coefficient (SHGC) values that are being required by more stringent building codes while maintaining higher transmittance and are more affordable than the traditional double and triple silver low-e coatings.
This presentation will discuss how nanotechnology is evolving the building industry, namely advancements in glazing coatings, allowing thermal protection to be more affordable and effective than ever before. Certain nanocoatings use solvent-borne metal-oxide nano-particles and an inorganic adhesive binder to form a self-leveling clear coat that is only 10 microns thick and is able to bond directly to glass and polycarbonate surfaces. This nanocoating is more cost effective than traditional window film, can be applied at either the manufacturing level or as a retro-fit, and is able to block up to 99.9% of UV rays, up to 85% of IR rays, and maintains up to 80% of VLT.
