My daughter’s bedroom is always 2 degrees cooler than the other bedrooms, all on the second floor. I measured with a laser temperature gun that the outside wall is 2 degrees cooler in only her room. Wondering what are my options for insulation in a finished room without taking the walls down, unless that’s the only way? Thank you
