|
|
I just moved to a new house and would like to take steps to reduce the heat in the attic. Of course the best time to foam a roof is while under construction. Is it practical to foam those areas one can reach after the house has been built? In addition to increasing insulation for energy conservation, I want to reduce the heat in the attic so stored items aren't damaged.
Suggestions? |

| I disagree. More insulation will help the interior of the house. But I do agree about using radiant barrier and as much ventilation of the attic space as possible. I remember when the big push to get away from wood shingles on houses and the houses started having problems cooling. My solution which was usually the cheepest was to ventilate the attic with turbine vents and sophet vents. Dont use spray foam, it is not as good of a thermal barrier as blown in insulation. |

Ron,
Actually you caught my interest in the solar powered ventilater, I have not seen any of those yet. At the time I was installing turbine vents (15 years ago) solar ventilaters were not offered, the only other option was the 120v power ventilaters most did not last 1 year. I would like to find out more on the solar powered ventilater. |

Where can I find these fans? I need to ventilate my attic but I don't like elctric fans (not very dependable and use the energy your trying to save)and whirly birds really do not move the air fast enough to make real differnce(my personal opinion). Being an old rafter rat I should know.
I have about 2200 sq. ft. of attic space and they put on black shingles when the house was built. |

Have you investigated passive solar energy?
Depending on your construction, you have several options, such as ridge vents. These range from styles barely noticeable to the huge contraptions seen on the top of commercial steel buildings. And could include a cupalo or a solar chimney. All depend upon engineering sufficient air imput. This would take advantage of the heat collected by the dark roofing.
On the subject of insulation, A couple weeks back, on a show from Florida, Bob Vila, <bobvila.com> I believe, demonstrated a "new" spray-on ceramic that was impressive. They held a short strip of metal by the end that had the coating on one side of one end, while applying a blowtorch to the other [bare metal] end!
Take care.
