Having an older home
A way to tell if you may need insulation or more insulation in your home is to be aware of what year the home was built. Prior to the consistent building codes, a majority of homes built before 1980 were not insulated. If the home has no materials or insulation trapping the heat, it probably has poor energy efficiency. Walls, ceilings, and floors are the most important areas to insulate. By insulating these, you can notice an immediate impact on the temperature of the home. You will also be able to notice a decrease on the monthly energy bills.
The furnace is always running
If you notice that the furnace is running non-stop, there may be an issue with the insulation. An adequate amount of insulation can lead to less stress on the heating system. Besides helping keep your home warmer and monthly costs down, insulation can help the heating system. The heating unit could last longer because it will run less. It will also require less maintenance because there will be less wear and tear on the system. This can help save you time, money, and stress in the long run.
Inconsistent temperatures in the home
If you feel cold spots coming from the walls or attic, you may need to add more insulation. Also if one room is drafty while another room is warm, there could be a lack of insulation in the drafty room. The fireplace, walls, and attic are typical spots for drafts. If this is the case, look for insulation that can fit snugly in the rafters or other tight areas of the home. This will help reduce drafts, as well as a loss of heat.
Hot spots on the roof
You can notice if the home has hot spots by looking at the roof. Shingles that are exposed after a recent snowfall is an indication of warm air escaping from those areas. Check the attic to make sure it has adequate insulation in it. If you can easily see the floor joists, make sure to add more. It is recommended to use insulation like stone wool. This is because it will not sag or lose density over time.
Noticing mold growing
Mold in the corners of the ceiling could mean that the current insulation holds moisture. If this happens, make sure to replace the insulation as soon as you can. An insulation that does not store or transfer moisture is recommended for the areas. That way it is resistant to mold, mildew, and bacterial growth.
