Will Blown-In wall insulation help with temperature control of my house?

I live in a one story single family house in the bay area of CA. One of the room, unfortunately assigned to the baby, in the house is especially cold at night and very cold at winter. I can tune up the heater, but then the rest of the house will be very hot in order to keep That room not-cold.


I wonder does anyone have experience with blown-in wall insulation, and can share with me how much it helps. I am sure our house is not side wall insulated, and we have efficient insulation in the attic.

So I understand you have central heating? It's hard with this system to regulate the temperature if a specific spot is colder (hotter would be as simple as closing the vent).





We have a problem in my house in our room, it's always freezing in the winter. The only solution is a independent heating unit (whether plugged in or you install one on the 220v).





So to answer your question, yes better insulation would help, but if the house is already well insulated, it won't change anything.Will Blown-In wall insulation help with temperature control of my house?
Yes, you can never have too much insulation whether you live in a hot or a cold climate; insulation lets you maintain an inside temperature different from the outside temperature at the lowest cost.





In the cold room, you should also carefully inspect around the windows for cracks. It is amazing how much warm air can escape through the smallest crack. The solution? A $2.00 caulking gun and a $4.00 tube of good caulking.





If the room is still too cool for baby, your least expensive solution is probably a thermostatically controlled electric baseboard heater. Buy one at least 30 - 36'; long, 1500 watts, 110 volts. Then you can keep the whole house cooler while maintaining baby's room at a more ideal temp. Locate the baseboard heater along the wall under the window.
Wall insulation will definitely help you control the temperature in your home. Not only will this type of insulation help keep your home warm in the winter it can also be effective in keeping your home cooler in the summer.
Any insulation in the walls will help maintain the temperatures. Blown in is the cheapest and easiest.
Also double-glazing the windows will very much help.
