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.

Hi Roger, This is outdoor use up to 105F, but I don't think this door lock good for low temperature -5F

With proper ventilation (to keep your roof cold) and insulation (so house air doesn't warm it up) you shouldn't have any ice damns so will be OK. I redid all that on my place before installing the guard, so don't know how it does with heavy damning. Without damning it has held up fine in the snow.

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

I just installed it,but appears to stop the drafts i had with other stripping. looks like it will work well in zero weather. Easy to install, fits tight even if your door is slightly out of plumb. I would buy it again.

That would probably work. The more insulation the better. I would use some kind of reflective like it type material for maximum heat. Good luck.

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. :)

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 got these covers in cold weather . I know it Will be easier to install in warmer weather . I canot answer your ?

Yeah, you surely could. I am from Minnesota and have installed 7 of these. The black rubber does a couple of things, first, covers the 2 3/4 hole that a normal door knob fits in and secondly, provides a gasket for weather and moisture. So, if you didn't use the black gasket, the hole must be smaller, or you'll see through the gaps to inside and you have to use a type of weather gasket. Thanks and good luck! They have all been flawless for me, even in -40 degrees during winter.

I don't know for sure, but I think it works with both heat and light. I think that the exterior door would be insulated to prevent the heat attraction and as long as the seal on the door is good light should not be a problem either.

I Do not Know, but I am using in drive-way in motion activated glass fixture. Do not know its impact in winter.

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.

Yes, if your doors are glass and not plastic. The company specifically recommends it on their website.

It depends on the size. Window glass is not necessarily and good keeping in the heat. I use this unit in my garage in between my two work benches - just to take the chill off my feet. Good little unit that my purpose.

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 I am using them on metal French Doors that are exposed to all weather, including snow. Work perfectly.
