A recent article by Yahoo! Finance listed out a handful of products and services where spending a little more up front will have you saving more money over time.
Insulate your home to save energy and money.
When it came to saving money around your home, they suggest paying what you can best afford on:
- Home Insulation
- Light Bulbs
- Energy Saving Appliances
Take the Home Tour and see what you can save through energy saving practices.
I do not see any mention, on your website, of the use of reflective technology devices, such as “Energy Shield” ( http://www.apsnrg.com ) blanket on top of the conventional insulation in the attic of the house. Do you think such devices are not effective?
Reflective barriers block radiant heat only. Once a layer of dirt settles on these they are no longer reflective. Heat also moves thru conduction and convection.
Building Science experts recommend you air seal the areas adjacent to your attic and then add insulation as needed up to a recommended R-49. Once properly air sealed and insulated, the hot or cold temperatures in the attic will have little effect on the adjacent rooms.

I would like to know if foam insulation on the underside of the roof and sealing all vents so that the attic is 10* difference than the living area is better than blown insulation. The duck work and furnace would not be in a hot or cold area. Would open cell or closed cell be better. I have been told that closed cell would make the home stronger in the wind. Would there be any moisture issues here in SC close to the coast. Would this be good or bad for the life of the roof.
I understand foam insulation is superior for a new home but how about one that is 3 years old.
