Insulation (cont., p. 10)

 

Things You Should Watch For

● Hire an experienced, licensed, insured insulation contractor with good references ─ whom you actually called.  Make the hire well in advance of when they’ll actually be needed.

 

● Make sure insulating foam is used around windows and exterior doors.  

Stuffing pieces of batt insulation into cracks isn’t good enough.

● Use foam wherever holes are drilled for passage of wire and pipe from heated to unheated areas.

Foam is not needed if the passages are interior with heated areas on both sides.

● Make sure dead areas behind tubs and in wall corners are insulated.

 


● Depth is critical when using blown, loose-fill, attic insulation.  A vertical ruler should be posted to make sure they get it right.

● Walk the entire house after the insulators finish. 

If you see a place that doesn’t have insulation, but looks as if it should, you’re probably right.

Verify this with the contractor.


● Insulation function is measured in “R-Value” (resistance).  Higher R-Value is always better and always more expensive.


It’s possible, however, to keep piling on R-Value at an increasing cost that ends up being overkill, and not really cost effective.


A reputable contractor will tell you when you are reaching that point.  You may compare his recommendation with Department of Energy R-value Recommendations.
