Will Installing this on all 5 of my double pane Sliding glass door help keep in heat during the winter?

Yes, it will. Low e coatings reflect heat back in the direction it comes from (it is not an insulator, but a reflector).

We have this film installed on our front storm door. It is opaque during the day from the outside and we are sure that this helps with the heat. We think that it probably does help to keep heat in during the winter but probably not to the level that heat is kept out during the summer. We are very pleased with our film. It was easy to install and does add to privacy during the day as well as keeps heat out in summer and to a lesser extent keeps heat in during the winter. We live in Mississippi and the heat out factor is a lot more important to us.

I only have one sliding glass door, and it's under a patio canopy so it's in the shade and that room is pretty cool these days. Sorry. We noticed a huge difference in keeping the summer heat OUT, but haven't had enough winter cold yet here in the Phoenix area to judge how well the heat stays in (still have not turned the heater on for the winter, but we hear that is normal for this area).

I do not believe this is designed to provide any insulation in the winter. It is designed to reduce sunlight thru the window to keep sun out in the summer. It may actually keep you from getting the warmth of the sun in the winter.

It is a heat-reflective film. However, I'm unsure if this works equally well in both directions (like insulation would.) This is a question best answered by the manufacturer. One thing that may differ is that in winter, the heat loss may be more due to conduction rather than radiation. The film would only be effective for radiative heat for the most part.

I have found it absolutely effective in summer to keep it much cooler inside but have not noticed a difference in the winter. If you do use it, be sure to read the reviews on installation, especially the part of having two people, using lots of lubricant (slightly soapy water works fine), and using the clothes pins to weight it down. Install the least visible door first, so you can learn by your mistakes. Be aware that you can pull too hard and stretch the material, and wind up with creases as a result.

If you can install it UNDER the pane-dividers, it will be more secure. Remember that the glass will still break, so I'd be afraid of the smaller panes breaking out of the frame, unless the whole of the glass in the door were covered.

Yes, my minor issue was that my insulated garage door was too thick. Easy install on any thin door. Great product.

Hard to answer that question since I don't know the weight of the 'insulated curtain" also since this is a single panel on a sliding door I assume that it gets some traffic. this will put a lot more stress on the rod in the center. I would suggest you mount it above the frame of the door and use the center support, assuming 36" door panels you can still open the door with half the window/door covered or just move both panels to the outside. Panels usually come 2 to a pack and only one panel across the whole 6' may not get you the effect you want. Since this is a double rod I use it with a gauss panel on the window side with sun blocking panel on the room side. All my windows are low-E glass with argon fill, so insulation is redundent. I got them a great price at Lowes custom made to my exact opening, at 25% of what a window company quoted me and delivered in 2 weeks.

Yes. My friend bought the one on the roller for a large sliding glass door & yes it blocks the sun therefore reflecting the heat.

I live in my camper and have a roll of this foil that I bought to add to the insulation this spring. However during the last cold wave I used some of it to cover all openings and windows temporarily. It kept the heat in and didn't interfere with my wifi (router is out side) or my phone that I noticed. I can't say anything for sure except that I didn't notice any problem.

I guess that could be true as all the windows probably won't be covered. BUT...it definitely lessens the heat on myself after I put them up. I have even put one on top of another at times when I wanted more shade. They are so versatile, awesome and cheap! You can put them up quickly and take them down quickly (which I often do when we change direction and sun is in a different place or if blocking view for driver). I also often fold one in half and stick it on part of my passenger side window when I don't need the whole window covered. TIP: I found when I put them on the dash in the sun to warm up for awhile before putting them up, they cling better. Hope that helps!

Haven't had any issues using these for heating or cooling and I have 3 of them on the main level of my house. You should be fine using these on your vents in the winter unless they get really hot. If your vents get hot enough to melt plastic, you have other problems. :)

as in all suction cups they won't work on very frigid weather, if they are hanging, but in this case where the Universal Cup Holder Suction mount is placed on the cup holder which is not hanging, it will surely work and at the same time your heater is on.

Depends on how you keep your thermostat. If you keep a constant 80° in your house you would be okay. But if you live up north, you probably don't and would need at least two of these.

I've not noticed but I only had them during this winter (cold). There's no reflective coating so I'm guessing they wouldn't keep the heat out. I'm assuming you're referring to something like a windshield reflector that covers the entire full windshield. Even if they were reflective they're not big enough to cover the entire windshield.

Yes it would, we have awning windows, so we opted for the sliding door kit. BUYER BEWARE!!!!!!!!The unit broke down after 3 weeks and Haier didn't stand by the product. It took from July to OCTOBER to rectify. They finally sent a new unit. GOOD LUCK

Oh yeah! It'll work perfectly. Just don't leave them on during winter. I ruined two that way.

It's perfect for a sliding glass door. I have it on mine. You will install it between the door jamb & the immovable door. Works great!

Hmm. Aren't you supposed to put a fanless convection heater in front of the coldest area. A sliding door should be ideal. That's how the heat spreads around because of the differential in temps. That's the point of getting a fanless convection, I thought.

Not sure. I haven't tried it on my glass door. I have glass tile and it works fine. I love it
