I have been doing quite a lot of work to insulate and protect my home but I am losing heat despite my best efforts. I have a good idea that heat is getting lost in the walls due to poor insulation.
Here is what I have done:
1) Replace all central air ducting with metal ducting, sealed with mastic and wraped he ducts in R30 insulation and further added kraft radiant barrier material around this.
2) Replace the heater and AC with 14SEER and 90 OSF units.
3) increased the insulation to R75 through a combination of cellulose, R35 faced batts and unfaced R29 rolls.
4) Added a kraft radiant barrier to the attic.
5) resealed every duct, hole and gap with epoxy.
6) Added passive whirly birds to a total of 6 units and two large gables on a 1600sqr foot house.
7) Insulated all the outlets and pipe leads to the outside.
8) Replaced all the windows with vinyl windows. I added solar film available at ***** (the winter insulative type).
9) Replaced all the entry doors with new insulated doors that are properly sealed.
10) Repainted every room with radiant paint.
11) replace the furnace filter every month.
12) Run the fans constantly in reverse to pull down heat.
13) Added an electronic thermostat.
14) open blind during the day (winter) and close them at night (winter) - we do the opposite during the summer.
But I still am losing heat. I just cannot figure out where. I bought one of those infra-red emperature readers and found that heat is disappearing from two spots: 1) the windows and 2) certain spots in the walls.
My home is more than 30 years old, but I have pretty much modernized it as far as I know how to.
The windows are low-e windows with solar films I added myself. But the windows are about 2 deg F colder than the walls. Using the infra-red thermometer, you can see the cols spots in the walls too.
Do you have ideas where heat is going to? Do you have any suggestiong on how I could improve on what I have done?
