Hi there,

The windows in this building are treated for UV protection, so to be honest that is where I would begin. A U/V film or window treatments (even sheers) will go a long way. Just bear in mind that if the factory has not applied a window film, it will often void the warranty on your windows - so do your research!

The rest of this question should be aimed at the showroom or manufacturers you are looking to purchase from. Not all materials are processed or finished the same way, and so they are going to be the best source for this information.

As far as cleaning goes, we have seen our cleaners do some amazing things with leather upholstery, but there are some things they cannot fix. In our experience, sun discoloration is unfortunately one of those things.

Good luck on your project!
