Make an Airtight House - well, almost
Make insulation in your home more effective with an airtight house. I don't mean absolutely airtight, but as close as you reasonably can. This makes your insulation more effective, and it supports a common objective of saving money.
Air transfers heat rather poorly when it's not moving, and much better when it is. That's one of the main reasons to seal up your house. Good insulation is wonderful, and making it even more effective just takes a little sealing with caulk or spray foam sealant.
Moving air also causes outside air to infiltrate places where you don't want it, and when you don't want it. That means pollen and dust in the house.
It's okay to have a window open at night in the summer to let in fresh air and a cool breeze, but warm air getting pushed into your home during the heat of the day isn't exactly my idea of comfort. In the summer, infiltration makes your AC work harder.
In the winter, you're paying more for heat or putting more logs on the fire to compensate for heat that is getting pushed out of your home. After all, if cold air is moving in, it has to be displacing warm air inside that you paid money to heat up.
Making an effort to achieve an airtight house will help minimize air quality and energy conservation problems year round.
Here are some weatherproofing tips that you might try to minimize unwanted outside air:
- install storm windows
- caulk cracks in your siding
- foam fill voids in your walls
- install pre-formed insulation in switch and outlet boxes
- plug utility penetrations
- replace door seals
- install storm doors
Every little bit helps to make your home insulation more effective and keep unwanted air from intruding into your home.
For problem areas like entry doors, consider building a vestibule or wind break to lessen the driving force of winds that can find a way into any place that isn't well sealed.
If one of you objectives of frugal living is to make your energy dollars go farther, then you have to take action to make an airtight house, within reason, to help your insulation be more effective year round.
