Grillage Bolar Inc.

Since it was founded in 1946, Bolar has been designing and manufacturing highly effective foot grille systems.
At the time, this type of system didn’t even exist. In fact, at the turn of the 20th century, all Canadian buildings were heated by one or more furnaces, which were usually located in the basement. As a result, ventilation grille systems were installed in the floor to circulate hot air. Over time, this type of grille system became obsolete with the advent of new heating technologies.
