Door Seal Design

That winter vortex may be over, but winter is still here for another few months so I am still not done dealing with door seals.  I have the door drape from Bane clean and that has been my method for the last few years, but it really doesn't seal all that well.  I've also tried the old moving blanket method and pool noodles, but they are not the most professional approach either.

While doing some work this past week, I spent some time studying the sealing methods used by many industrial buildings to seal off an area....namely thermal curtains or drapes.  I looked at one from Goff that looks very promising.  They have thinsulate and seem very durable.  It was being used to seal off a dock area and it made a pretty big difference in temperature between the two areas while staying flexible.  They use a tracking system which wouldn't work, but it looks like they could be hang using an expandable curtain rod or even held into position using the Zip-wall system.

They come standard in 60 inches at any height that you desire.  That is a little wide for a door way, but not by much, so I figure a standard sheet at 7 or 8 foot tall should do the trick.  They will even place your logo on them if desired, which might look nice from the street when you are working.  Oh, and they come in several colors as well.

So, what do you think....how about some discussion on how to make this the perfect door seal system.  

Should it be hung using an expandable curtain rod between the door jams or held up with zip-wall poles?  Any other ideas?
Should it by modified with a double-sided zipper down the middle so that you can pass through it without pulling it all down?
Should it mounted outside of the door maybe, up against the exterior instead of the jam?
Would this be too cumbersome and heavy for your tastes?  The one that I handled was 10 ft tall and weighed maybe 10 lbs.

I like how you always go outside of the cleaning biz to find solutions to problems. That drape does look pretty bulky but then again that was the full size drape. Maybe you can use magnets like the Majic Mesh does

I think I hear a mosquito laughing  

Interesting use of magnets, not sure if that would work. I'm taking my drawings down to the shop tomorrow to get started on the prototype. I hope to have an early version done this week and I will post it then for feedback.

Sealing the entrance isn't just for winter either. It holds the A/C and pets inside while keeping bugs outside in the summer as well. If anyone actually made one that worked, I think customers would be impressed by the considerate cleaner that used it. Cleaners like the ones on this board perhaps?

If you can make one that works and provides easy access and exit I'm sure a few other cold cleaners would like it too 

Thanks Mo, I'll see what happens.
