A method for sealing a dryer against leakage of hot gases from within the dryer through joints between adjacent panels enclosing the interior of the dryer. The method comprises fastening respective elongate enclosing members into abutment with mutually adjacent pairs of panels along the joints between them so as to form respective enclosures between the enclosing members and the panels at such joints. Thereafter, at a temperature less than the operating temperature of the dryer, a heat-resistant, gas-impermeable closed cell foam is injected into the enclosures through spaced perforations in the enclosing members so as to substantially fill the enclosures. Thereafter, when the veneer dryer is operated at its normal elevated operating temperature, the temperature of the closed cell foam is thereby increased so as to expand the foam within the enclosures into tight sealing abutment with the joints to prevent gas leakage therethrough.
