Why is my bedroom so cold after foam insulation was installed?

I insulated my front bedroom above my garage with foan insulation under my floors and also my exterior walls, my house is 35 years old with shingle walls in the front of the house with brick on the sides.
The cold still comes in and its the coldest room in the house.
The attic is very insulated, so i dont know why this is happening.

Thanks for your help

How is the air-flow?

It doesn't take much - a small hole or crack - to allow cold air to pour into a room like water through a sieve. . . check your ductwork - is it insulated properly? Is it functioning properly without any rust-holes in the ductwork (etc).

How about your windows and window casings - are they secure, insulated behind? If you touch your window and it's cold - that could be your problem . . . consider new windows but in the meantime perhaps the insulating shrink-wrap is good (sheets of plastic are attached to the window-casing with double-sided tape and then using a blow-dryer shrinks it tight . . . this prevents air flow).

Are there holes around pipes or wiring (in the floor or ceiling) that would allow air to pass through?


At this present moment in time I am making cabinets for the kitchen - just in case you wanted to know what I'm doing when I'm not around.

Also, can we get more info on the foam? What kind? How much? What is professionally installed, etc.

Also, is the garage insulated?

If the garage is uninsulated it's possible that there just isn't foam.

The other possibility is that your bedroom is not gettting enough heat. How is that room heated ?
