Hi all,

I have a serious summertime problem. I do not have central air in my house and the windows in my theater do not support AC units. The room is 12x15. One of the 15' walls is essentially all windows and one 12' wall is also windows. I have shades (cheapo white roll down from homedepot) that adequately block light. The problem is that the sunlight passing through the glass heats the hell outta the place. Is there some sort of UV blocking plastic or something that one can stick to the glass to prevent this? It gets hotter in the room that it is outside sometimes (90 degrees!!!). I have a portable AC I wheel in there but it is loud and only 8000BTU (about as high as these units go for $1200!!!).

Thanks in advance

FREAK!

Certainly not an expert but with that many windows you are not really in that great of a situation without spending a bunch of money.


Have you thought about tinting the windows? Thay may help cut down on the light getting in and possibly cut down on the heat a bit. You may also find that heavy drapes may help cut down on the heat transfer into the room if they have a reflective (white) surface that faces the windows to act almost like tinfoil does to try and isolate the heat between the curtain and window.

Yes, there are a variety of custom applications to address this. One of the more common is adding a second (or third) pane of glass or plastic which can have a low e coating. These can be custom built and can fasten to the inside or ourtside of your windows in a variety of ways, one being via magnetic strips. These types of retrofits are commonly done on motorhomes and large trailers to winterize them however I don't know if they would do homes. I do know that there are specialty companies who do though. It should be just a matter of going thru the yellow pages and looking at window/door specialists and energy management retrofitters. Alternatively, there are also tinting kits you can apply, or have someone apply, similar to having a car window done. These will not be nearly as effective as the first suggestion, but likely a lot cheaper. And of course, don't forget about good old aluminum foil. Ugly, but it sure does keep the heat and light out! Good luck.

Keep in mind that some film treatments will heat up the window and can damage the seal for a dual pane window. Also some manufactures will not honor their window warranty if a third party film is applied. I saw a reflective film that you put on the outside of the window at some web site and it was claimed to be safe for insulated glass.
