Blowing in insulation - which companies do it best?

Original post made by Susan Strain on Jan 24, 2008

I rent an old cottage and propose to pay higher rent to be warm in the winter (and not too hot in the summer). Some companies (Eagle Shield, Bay Valley) won't give you an estimate if you aren't the landlord, so I'm not interested in them. Of the other companies, has anyone had a good or bad experience with them? Was the insulation worth the money? Did they leave the ceiling, etc., in paintable condition, or did you have to spackle? Were there any unexpected drawbacks?

I had blown in attic insulation put in many years ago, the company no longer exists. But they dragged the hose thru the trapdoor into the attic, no holes in the ceiling were necessary.

Now I would ask, is it better to have blown in insulation on the attic floor, or batts of insulation on the inside of the attic roof. The latter might help avoid heat buildup in the summer.

Walls, I can't say.

Walls can be blown in, its more expensive, they have to drill 2 ~1 inch holes every 16 inches in the wall. So you have to plan on a paint job after the work is done. When I remodeled my barret and hilp house, there was no wall insulation. Since I opened up the walls, I could put in batts.

My house also used to have metal casement single pane windows. There are a lot of these in P.A. These are about the worst windows to have in terms of heat transfer.

These smaller houses were built cheaply when energy was cheap. There are a bunch of opportunities to make them more energy efficient while not sacrificing personal comfort.

Do the ceiling, then replace fenestration. Then elect a leader who will drill Anwar and offshore, and build nuclear power plants.

you can also do batts on the attic floor which is the easiest to self install. If you put the insulation against the roof the problem is with the roofing materials. If your roofing materials use the attic space air to dry out after a storm, you dont want materials trapping moisture against the roofing materials.

Another method to avoid summer heat build up is an attic exhaust fan, or lighter colored roofing materials that will reflect some heat.

RS is correct. The concerns lately about mold make under roof ventilation a concern.

oh something else I missed, it you were to put the on the attic roof instead of the attic floor, you would end up paying to heat an unused space as the heat from the home will still leak into the attic from below.

I own an older Barret and Hilp home and have been experiening odd floor problems with moisture pushing the oak flooring upwards. Has anyone else experienced this problem?
