An oven for heat treating, curing, stress relieving or otherwise treating objects within the oven has side walls that can be moved into contact and out of contact with side edges of a movable floor. All interior surfaces of the oven are insulated and, when the floor is located in the oven, the side walls can be moved so that the insulation on the side walls forms a sealed relationship with the insulation along the adjacent side edges of the floor. A door of the oven can then be closed. When the door is opened, the side walls can be moved out of contact with the floor and the floor can be removed. Preferably, the side walls are moved by the operation of pneumatic cylinders.
