Review: cheap and quick fix! - Coming into the winter season, I get a draft from the hallway in my condo building, especially living on the main floor, and it's like AC coming I to my unit. As a renter, I bought this based on the reviews saying it was easy to install and to remove with the adhesive. I only prepped the door with the alcohol wipe, letting it dry before adhering the strip to the door. I don't want it to ruin the paint by making the adhesive too strong when it comes time to remove it. For removal though I would use a hair dryer to help make it sticky. For this being a two pack, awesome deal and fixed my problem with the draft! It's helped reduce some of the hallway noise as well. highly recommend
Review: Bas de porte insonorisant - Je suis très satisfaite de mon achat. La bordure de caoutchouc est très facile à poser. Dans mon cas, je l'ai posée sur une porte de métal et la bande autocollante adhérait parfaitement. Je ne l'ai pas acheté dans le but de réduire les courants d'air mais bien pour ses propriétés insonorisantes mais cela fait les deux en même temps. C'est super!

## Questions & Answers

**Q: can I double one on top of the other to cover a larger gap? If not, please rec a product that covers a 2" gap. Thanks!**
A: No, that won’t work, I tried! Order this instead. It’s more expensive but super thick and sticky, comes with brads as well and closed over a 2” gap on my screen door. Yahhh …no more critters can get in! I’m ordering another set today to do both sides of the storm door.

**Q: Can it come off easily without ruining door?**
A: Yes, mine did. You may need to apply a blow dryer to heat it up some. But it comes off.

**Q: Will this damage a painted door or wood door upon removal?**
A: Yes, it destroye the paint on my bedroom door don't do it!

**Q: Does this work better when placed inside or outside the door?**
A: If it is an interior door like a bedroom door, you can put it on either side.  If it is a main door leading to the outside, I recommend using it on the inside.  You can put it on the outside but weather conditions will deteriorate the quality of the product over time.
