Door Seals, do they help with heating costs?
« on: November 16, 2014, 05:06:50 PM »
My Mom recently sent me a link to these door seals, and I was wondering if anyone has had success with them or similar products?

My landlord put one of these on our back door a couple of years ago. HUGE difference in the indoor temperature. We have radiator heat so I can't speak to the $ savings, but it made a world of difference for our comfort level.

I made some very similar draft blockers using a sewing machine and some pipe insulation.  This is their first winter in use, and my apartment is still comfortable in mid-November and the heater hasn't been necessary.  Last year it was a struggle not turn on the heat in late October.  Qualitatively, the apartment is so much nicer without cold drafts blowing through from the balcony door.

Sounds like they might be worth it then.

Done and done.

Thanks for this post. Last fall I did all the research, made the door seal selection but never made the purchase. Just in time, too, it is (literally) freezing outside...

For exterior doors, these look like they might help if the weather stripping on the door is bad.  me, I'd just fix the weather stripping.  There should be a seal the door closes against at all edges, though some doors have a bottom "sweep" rather than close against a seal.

For interior doors these might be more useful, but keep in mind that a forced air furnace is designed to draw return air through many parts of the house.  Blocking this airflow could reduce heater effectiveness.  Ditto for bathroom fans, there needs to be a 3/4" to 1" gap under the door for airflow.

They shouldn't be too difficult to make with some fabric, elastic and a couple of pool noodles.

I just bought this two days ago and it has replaced the random rolled-up towel in front of the back door.  The floor around the door is definitely less cold, but our house is pretty drafty overall, so I suspect we won't see much difference in heating costs.

These are most useful for apartments/condos (not an outside door).   It does help with drafts in the winter and losing less cooled air in the summer and with noise from outside hallways.

I definitely noticed an improvement with the above when I installed it.
