Windows could save the planet.

Heat reflecting Windows
A new windows invention could help save the planet by illuminating the office, but keeping the heat out. Does that sound like the opposite of Microsoft Windows, which generates a lot of heat and leaves most users in the dark. That might be because it%u2019s got nothing to do with Bill Gates.

It can take the heat

Windows helped to create the original industrial revolution. Now windows could minimise the damage


The invention by Sumitomo 3M is a new transparent window film. Initial reaction to it was cool – as you might expect, reports www.nikkei.net. But what a difference the Kyoto Protocol made.

Suddenly everyone’s desperate to cut their CO2, if only to please their boss. So Sumitomo is being over-whelmed with orders.

The window film, the Nano70S, selectively reflects the infrared part of the sun's spectrum, letting in light without neutralising the air-conditioning. With obvious energy savings. And, air born viruses don’t circulate around the building, there’ll presumably be less sickness too.

The Nano70S is a multilayer PET film 50 microns thick in total. It blocks over 90 per cent of the light with wavelengths over 780nm – the infrared end of the spectrum, in other words. The other 70% of light, the visible part of the spectrum, gets in.

As an added benefit, the window film can stop glass from shattering if Wiggins from accounts decides to end it all in a spectacular fashion.

As we all know, Windows has a nasty habit of crashing, you see.

And it won't crash
