My house is 125 yrs old. It's November in Utah. BRRRRRRRRR... I am looking for genius (CHEAP) ideas to help us stay warm. One situation in particular...
I have a finished attic (no heating ducts) with no stairs. It is accessed through a ladder in my bedroom closet. Needless to say, it's the cat's penthouse. The rest of us are too lazy to go up there. SO... there was a door on the closet, but I removed it, because it prevented me from organizing my bedroom normally. (I love old houses. I love old houses). So.. I hung a curtain there, and this allows the cat to sneak through. yet... I know that the hot air in my bedroom is rushing straight up that entrance to the attic. So... is there a more efficient way of plugging that hole and still allowing access for my kitty to get through?
I feel bad because I already plugged up her kitty door to the back porch because it was letting too much cold air in.
"Always remember that you are absolutely unique. Just like everyone else."
The kitty door to the back porch is probably the most energy efficient of the 2 options.(You are loosing heat upwards not sideways) You should be able to find a more efficient style of cat/doggie door, one that prevents drafts. If no one is using the attic cover the hole with a sheet of plywood/osb with insulation on top of it. A sheet of 2"thick styrofoam is light and better than nothing, can be attatched w/ double sided tape to whatever cover you use.
Be sure to remove whatever is in the attic that may freeze when you block the opening or you may have a bigger mess on your hands than you bargain for.
I'd definately cover the opening as suggested. Just think of all of the heat that is going up into an unused space. Not to mention all of the cold air that will be coming down through that same hole.
Brrrrrrrr, I'm cold, just thinking about it.
I, too, have a vintage home. I love it and wouldn't trade it for the world, but it does have it's issues when it comes to winter.
My doors slide into the walls and disappear (pocket doors)and on the inside wall there is a terrible draft that comes down through the open track every winter. I actually take duct tape and cardboard and cover up the tracks for that door, or I swear, I could make ice cubes in that area of the house.
None of the other pocket doors have that problem, so I'm not sure it the insulation settled differently when the house was moved out here or what the problem is. I've had several contractors look at it and no one has come up with a viable solution yet.
Good luck with your project. It's not worth it to use the attic as a playground for the cat, when you think of the hundreds of dollars you are wasting on heat every year to heat a space the size of your house twice.
