Abstract
A dual glazing window having a removable glazing panel is provided with a breather system connecting the air chamber between the glazing panels with the outside ambient air by routing an outwardly facing channel into the window rail or stile member either on its end edge or side face. The abutting rail or stile member will close the open side of the channel in the end edge while the adjacent glazing panel closes the channel in the side face. A breather sleeve is press fitted into the channel to protect the wood from absorbing moisture.
