Insulating Your House
ABSTRACT
The basic idea is to use the appropriate insulation within your home to save on heating and cooling costs. There are easy fixes and many new technology in insulation that will prevent thermal loss year round. The expenses might seem high but will be able to pay for themselves in years and create a more energy efficient environment. This article will discuss the different options and procedures available.
Physics Principles of Insulation
Building Materials
Insulators
- Choice ones that "retard the flow of heat from one object to another"
- High "resistance to heat transfer
- Porous Materials are Great Insulators
- This is due to the air in the pores acts as a "Good insulator"
- Choose darker objects = better emitter and absorber
- Darker objects > absorber/emmitter than white
- Thermos = bottle inside a bottle
- Device to reduce heat transfer - 2 bottles seperated by a vaccum = > heat transfer from to inside chamber

Common Mishapps When Insulating Your Own Home
- AIR LEAKS
- Unsealed gaps around: Joists, sills, windows, no weatherstipping around doors, Exterior Vents (Water Connections, Kitchen/Bathroom Vents, Dampers/vents)
- Cracks in Foundation/Walls/Chimneys
- Poorly fitted Air Barriers in Walls: Attach Hatches and Wall outlets
