Share 'Blown fiberglass + blown cellulose'
Our Crew Chief asked me this question today: I have an attic with R-25 blown fiberglass insulation. Is there any reason I should not install blown cellulose on top of it to bring the attic up to R-38? I can't think of any reason. Does anyone out there know of any reason not to install blown cellulose on top of blown fiberglass? Thanks! George Kopf
