Heat from radiators or underfloor heating can also disrupt a WiFi signal, and you can focus a signal from your router to a fixed device like a PC by positioning a reflective surface beside the antenna on your PCI card.
Substances with a more reflective molecular structure will block WiFi signals better than materials that absorb the signal. Thicker items block the signal better because they provide more material for the WiFi signal to carry through.
