Save Energy: In winter and summer, a door draft stopper is a great renovation item that can prevent air conditioning and heating leaks, making your room more efficient in terms of cooling or heating, saving you electricity and money. The door draft stopper works on many doors or windows, such as glass doors, screen doors, sliding doors, wooden doors, storm doors, etc. Perfect Design: The door draft stopper's triple-sweep design effectively reduces noise, prevents dust from entering through the door, and keeps the room quiet and clean. The self-adhesive insulating door draft stopper is very suitable for covering gaps in exterior/interior doors, RV doors, shower doors, baseboards, thresholds, windows, garages, basements, and furniture. Quality Materials: The cold insulating door draft stopper is made of silicone, which can bend and deform. The draft excluder for the bottom of the door is very flexible and won't damage your floor. The door strip is also very durable and has a longer lifespan. Easy to install: With strong adhesive, the door seal is easy to use; simply cut it to the correct size according to the size of your door. Please ensure the surface is dry and clean before installation. Then peel off the adhesive backing and stick it to the door! Please press the door seal firmly several times after the adhesive has set and leave it for 24 hours. Note: In cold weather, we recommend heating the adhesive for 2 minutes with a hairdryer before installation. The door seal may not function properly if the wall surface is rough or textured.
