check out this new insulation - you probably learned all about it in school, the physics of reflecting heat/cold. Yes, it is that silver foil shiny stuff, with about 1/8" of polymer (that comes 80% recycled), and IS recycleable (not currently through actual city pickup, but they're working on a solution for that!).

anyway - in its various applications - roof rafter, ceiling or floor joists, in-wall, can offer R11+   ----and the product is only 3/32" thick!!!!

not only can you save on lumber costs (new construction)

Low-E Insulation is a simple to install & environmentally friendly reflective insulation product. By providing high R-values either stand alone or in conjunction with mass insulations Low-E can help increase energy savings.

Low-E can be used in all facets of the building industry where conventional insulations are used. This includes residential, commercial and recreational applications. It can be used alone or in conjunction with mass insulations for high R-systems.

 

The second Law of Thermodynamics, unlike man made laws, cannot be broken HEAT goes to COLD by one of three ways: CONDUCTION, CONVECTION & RADIATION. 

WHAT IS CONDUCTION?

When two surfaces come in contact, the warmer surface gives up heat to the cooler surface as can be seen with a glowing burner on a stove heating the pot it is in contact with. In a building this is limited primarily to studs connecting outer and inner surfaces

WHAT IS CONVECTION?

The movement of air as a result of air being warmed. Warm air rises seeking the coldest point. Convection is visible as wavy lines above a hot road. Convection is a major concern in the winter, but not in the summer. 

WHAT IS INFRARED RADIATION?

Electromagnetic waves that can only be seen as part of the rainbow. It travels at 186,000 miles a second. Radiant energy travels in all directions seeking a cooler object to strike and then generates heat. Microwave ovens work on the same principles. Standard ovens heat the air, while a microwave heats what it sees.. Infrared is like microwaves at lower frequencies. Most of us do not understand microwaves or electricity but we use and enjoy the benefits of them. We may not understand infrared radiation but we can learn to make it work for us by learning how to control it.
