How to stop heat transfer through a sliding glass door?

Question

Does anyone have any ideas for stopping (or minimizing) heat transfer through a sliding glass door?

I live in Phoenix, AZ. I own a condo with a sliding glass door to the backyard. During the day I can feel the heat coming through the glass. I have vertical blinds on the door that stops some of the heat, but it still gets really hot in the room.

The door is in the shade 95% of the time...it's mostly just the hot air. So putting an additional shade in front of it won't do much good.

Any ideas of additional methods for keeping out the heat? Anything I can add/put onto/put in front of the door to slow down the heat transfer?

Thanks!

Answer 1

I recently screened a house in Texas. I choose the "No Seeum" material for all of the screens. There was a significant drop of temperature in the house afterward. I choose to do the job myself, purchased the materials and took a Saturday to do 18 screens. Once you do the first one, the job becomes easier. My GF couldn't believe the difference. I did the screen on the backdoor first, so that she could see and feel the difference as it was slide open and closed.

The other option would be to coat it with UV protective window film. You can find it in the same stores you would find the screening materials, LOWES, HOMEDEPOT, ACE TRUVALUE, or most any good hardware store. You can choose tint percentages and mirrored or unmirrored finishes.

Either way, you will see a noticable decrease in your electric bill. Her's dropped by nearly 22% during February.

I hope this helps.

If you really want to see a change, do both to your windows.

Answer 2

if u wanna reduce the heat transfer....i have good idea
if you'll buy a additional shade just add it with leaving some distance between two shades.because air has a very low heat
conductivity.no need to buy a very thick shade just a thin shade is enough because after all these changes max heat is stopped by air between two slab.so it will reduce the heat transfer.the the one more problem is regarding radiation for which u should attach such transparent sheet on the outer side of the sliding door so it absorbs most of the radiating heat.or just use curtain on the outer side of the door in day.

A new sliding glass door with Low E coating, insulated glass and a frame material that is energy efficient. The window films can damage glass not designed for that kind of heat build up.

In remodeling and "flipping" we've put in heavy wooden blinds and even drapes but, this of course takes away from the view so, it's a matter of preference.
I use the heavy wooden blinds and when the sun isn't hitting the windows I can open them for the fresh air, I choose this over air-conditioning.

Possibly, depending on the thickness of the glass and it's distance from the ceiling fan, but I wouldn't want to find out the hard way. Didn't your mother ever tell you not to play ball in the house? Also, the door may very well stop the ball, yet still get cracked...
