1. Insulation: Insulation is a material designed to slow down heat transfer. It works by trapping air pockets or using materials with low thermal conductivity. Common examples include:
* Fiberglass insulation: Used in walls and attics, it traps air within its fibers.
* Foam insulation: Made from materials like polystyrene or polyurethane, it creates small closed cells filled with air.
* Vacuum insulation: Creates a near-perfect vacuum between layers, reducing heat transfer through conduction and convection. Used in thermoses and some specialized applications.
2. Heat Shields: These are designed to reflect heat radiation away from a surface. They often use materials like:
* Aluminum foil: Highly reflective, it deflects infrared radiation.
* Mylar: A thin, polyester film that can be highly reflective when coated with a thin layer of aluminum.
* Ceramic coatings: Can be specially formulated to reflect infrared radiation efficiently.
* Heat sinks: Used to dissipate heat, usually made of metal with a large surface area. These aren't technically a "shield" but are often used in conjunction with shields to improve cooling.
3. Double-Paned Windows: These windows use two panes of glass with an air gap between them. The air gap acts as a barrier, reducing heat transfer by convection and conduction.
* Low-E coatings: Added to the glass panes to reflect infrared radiation, further reducing heat transfer.
