Abstract: A dual glazing window having a removable glazing panel 32 is provided with a breather system connecting the air chamber 34 between the glazing panels 30 and 32 with the outside ambient air by routing an outwardly facing channel 38 into the window rail 26 or stile member 60 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 68 is press fitted into the channel to protect the wood from absorbing moisture.
