UV rays cannot travel through glass! The heat can but no UV rays can travel through!

@Kevinator56 That's not true. UV can travel through glass just like violet light can. Some glass though can absorb UV with special chemical treatment.

@marauderfh NO! normal standard glass like in windows door and even cars will not let UV light pass through!
