Attic insulation??
Posted: Sat Oct 03, 2015 4:37 pm
I have an opportunity to inspect and add blown in fiberglass insulation with a the new ridge vent system I'm having installed. I will blow in from the center peak opening before being covered.
Home is a 14X70 with joisted attic and shingled roof. I believe it's 3 or 4/12 pitch. FLAT interior ceiling throughout the home. (A full flat attic space) NO soffit venting at all. 2 big gable vents and a full ridge vent.
From a previous inspection through the hole for the bathroom fan, I realized that the insulation levels are between R13 and R19 and not consistent. I see some pulled back in the distance and it worries me that it's not right.
Anyway I know that the insulation must be on the attic floor and should not touch the bottom of the roof decking, but that is nearly impossible to not touch when adding blown in fiberglass to the edges of the roof. There is so little space at the edges Since there is NO soffit venting anyway, what is the concern with some insulation touching the decking? No soffit to clog!(The insulation touches the metal on metal/flat roof mobile homes. What is the difference in my case)? There are many old stick built homes with no soffit vents and insulation touching the decking at the edge of the roof, why would a mobile home be different? It would seem to me that, added insulation would help keep more moist heat from getting to the roof to condense.
Could someone tell me just how much and where to add blown fiberglass in my case whilw I have full access. Opinions are appreciated!!
Thanks, Todd
