Chores Made Easier: How Do Self-Cleaning Windows Work?

Window cleaning is supposed to be a relatively easy task. However, grime is notoriously hard to scrub off windows. There’s also the problem of the white streaks that are left behind after wiping the windows. So, you’ll be glad to know then that Renewal by Andersen® offers energy-efficient windows with self-cleaning glass.

Titanium Dioxide and Its Uses

Renewal by Andersen’s self-cleaning windows are coated with a thin layer of titanium dioxide, which makes it harder for dirt to cling to the glass surface. 

The two things you need to know about titanium dioxide is that it is activated by light (a photocatalyst) and loves water (a hydrophilic). Once light hits the coating, it releases electrons that make it harder for dirt to cling onto the glass and easier for water to wash off of the windows. Normally, however, water can’t wash off all of the dirt because it tends to form beads on an ordinary glass surface, instead of sliding down uniformly. But since titanium dioxide is hydrophilic, it means that all the dirt is washed off, and no streaks are left behind.

A Few Caveats

Keep in mind that the titanium dioxide coating can only make the task of cleaning windows easier, not eliminate it. However, if you don’t have time for chores like cleaning windows, self-cleaning windows may be a worthwhile investment. 

Renewal by Andersen’s self-cleaning windows are also energy-efficient windows, thanks to their high-performance, Low-E4® glass. Low-E4 glass can block 84% of ultraviolet (UV) rays. It also outperforms other types of glass when it comes to energy efficiency, being 47% and 56% more efficient in the winter and summer respectively.
