An oven unit for heat treating sealant strip material applied to the perimeter edges of a window unit includes an oven box having a pair of spaced-apart sidewalls and an upstream end for receiving the window unit and a downstream end for egress of the window unit after heat treating. The window unit is conveyed through the oven box by a plurality of rollers extending between each sidewall and arranged from the entrance end to the exit end. Interspersed among the rollers and located immediately adjacent and below the window unit are a plurality of lower emitters for generating and directing radiant heat energy upon the sealant strip material. An upper row of spaced-apart emitters also di- rects radiant heat energy upon the sealant material. Interspersed among the upper row of emitters are a plurality of removably insertable reflector housings with each reflector housing having mounted therein a cambered, removably insertable, heat reflective panel adapted to reflect and redirect radiant heat energy upon the sealant material for facilitating the heat treating thereof. The oven unit also includes a damper system to permit convective heat flow within the oven box to the atmosphere.
