Attic Insulation

Hi, my home was built in 1910. There is absolutely no insulation. The roof has wood shingles covered by a layer of regular shingles, no insulation and no vents. I'm looking for suggestions on how to ventilate and insulate the attic.

Insulation and ventilation


There is a wealth of information in the threads on this forum. Just about every aspect of insulation and ventilation has been repeatedly discussed. Sit back and read through the threads.

Ridge and soffit vents are the most efficient type. cor-a-vent.com

However if there is no sign of moisture damage then use a non condensating insulation such as a radiant barrier and you will have maximum performance. I would reommend a two layer material. It can easily be installed from the top in the joists.

The radiant barrier is about 95% efficient as compared to about 10% for fiber types.

You might also want to look into radiant barrier paint for the interior side of the exterior walls. They are about 70% efficient.

Thank you for considering my opinion.
