Article on fiberglass’s IR translucency
Dana has mentioned fiberglass’s IR-translucency several times. In a recent thread, it was identified as contributing to a particular heat gain issue. And I’ve experienced it myself after having blown fiberglass added to my attic and experiencing a positive difference in winter but a nonexistent to negative one in summer. If I’d known about this before having this work done, I wouldn’t have had it done it, either doing it myself or searching farther and wider for someone willing to use cellulose instead of fiberglass. Given the ubiquity of fiberglass insulation in North American markets, this seems like a really important thing to know about and I think it deserves its own article to highlight it. Maybe Dana could do a guest post!
