At the front of my attic I have two side by side windows. What I want to do is use the foam core as a backing for two hill scenes I bought to go across those windows. Question is the foam core will be exposed to the sunlight for at least half the year. Will the ultraviolet rays cause the foam core board to degrade. Any help greatly appreciated. Thanks Paul

Depending on how its reinforced it might be OK. I would certainly use some sort of backer on the sun side possibly even covering with aluminum foil to reflect the heat. Foamcore all by itself is not real stable. Glued up in a structure it gains some strength but still moves around a lot from variances in temperature, humidity, etc,. Russ
Russ, thanks for the information. That was helpful..................Paul
Hi Paul, How about using a thinner piece of Masonite (or Hard Board as some call it). You could paint the window side white to deal with the sun issues. If it starts needing maintenance simply repaint it. This would be light weight and easy to handle, yet durable and stable in this environment. You could install screws or nails or what ever to allow it to hang on the window frame/trim and be secure yet easily removable for cleaning. Any hole in the window frame/trim could be easily filled if necessary in the future.
Just an idea....

Mike M, Thanks another good idea. I never thought of that one. I know I have a ton of white paint. I'll get a 4X8 sheet and have it cut to the height I need for that area and also have a 2X8 piece cut for a backdrop on the switching...............Paul
Hi Paul, I'm glad if it helps. You should post some pictures of your project when it's done. I too like to use Masonite for back drops - it is durable (tolerates bumping, kids, etc.) and can be painted or changed easily. It is easy to mount things to with double sided tape or other easily removed adhesives (rubber cement and other such things). I have also used foam board for back drops in various situations, but always in "protected" places where it is sheltered from people and harsh environments. I agree with the posters above it would not be a suitable choice here.
Good luck with your project.

The Masonite would be the better sturdier way to go here. One other consideration is you may want to think how this will look from the outside. you did not mention of there would be Curtains or blinds on the window.
I did a quick measurement and the area will be 8 1/2" tall and 76" long. Masonite is the choice and painted white on the back side to reflect the sun. The two backdrops I bought will have to be cut down to fit the area. As I move forward with this I will post pics......................Paul
