* 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
==Types of Insulation==
**Fills small cracks/crevices easier
**Reduces air Leakage better
** Better sound reducer (then
** R-3 to R-4 value per inch
** Cellulose fiber > (by 30%) then loose-fill rock wool
**Sprayed on Wall, ceiling, and floor cavities
**Expands to sold cellular plastic with many air cavities
**Good for irregular shaped areas and around
**Require specific machinery to spray/mix
'''IF YOU NEED HELP DETERMINING THE TYPE OF INSULATION, CONSULT A CONTRACTOR OR TRY THIS SITE
*Monitor your energy usage form year to year*Call Local Power Company/Contractor about an energy audit*
Meansure depth of insulation between joists in attic if unheated*Re-caulk windows, doors, siding, dampers, vents
! Southern Zone
* Install a vapor barrier of 6-mil polyethylene on the warm-in-winter side of the insulation.
* Insulate the rim joists at the top of the foundation walls by filling them loosely with fiberglass insulation.
* Insulate an attached garage with faced fiberglass insulation, with the vapor
barrior facing into the garage.
* Don't compress insulation to fit: it needs air space to work effectively.
'''In the Attic'''
Estimated Costs (Energy and It's Uses in the Environment)
* Increased Insulation = save as much as 50% on heating/cooling bills
* Federal Minimum Property Standards could be reached nationwide is everyone saved
atleast 15% of current heating demand.
--The minimum insulation recommendations are currently
Celings have to now have a [[R value]] of 38, not the previous 19*Wall's [[R Value]] should be 19, instead of the previous 11.*Floors should have a 11 [[R -value]], instead of the previous 22.
Thermal Resistance = [[R value]]
***Higher R-value = better insulating properties
R-Values Per Inch For Common Insulating Materials*
---For a broader table please follow this external link
*"If the wind velocity increases to 15mph, the R-Value of the air film is decreased by 50%.
- ANSWERS TO SOLVING SUCH PROBLEMS
* Plant trees and
schrubs near house to reduce wind effects.
==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)
