The Sliding Door Challenge
Sliding patio and balcony doors are notoriously drafty. Their large surface area, multiple gaps, and wear from frequent use make them major sources of heat loss in apartments and condos.
Special techniques for sealing sliding doors in rental apartments
Sliding patio and balcony doors are notoriously drafty. Their large surface area, multiple gaps, and wear from frequent use make them major sources of heat loss in apartments and condos.
The sliding panel track creates a gap at the bottom. Use foam weatherstripping or door sweep designed for sliding doors.
Vertical gaps where sliding panel meets frame. Self-adhesive weatherstripping works well here.
Large glass surface loses heat. Apply window film or use thermal curtains for insulation.
Gaps around latch mechanism. Ensure door is locked tightly and check weatherstripping in this area.
Apply insulation film to glass panels as you would on regular windows. Large surface may require two people for smooth application.
Floor-to-ceiling thermal curtains are highly effective. Use tension rods or existing mounted hardware.
Special adhesive foam for sliding door tracks. Creates seal when door slides closed.
