Please double-click, for a somewhat larger image. This is an installation I will be trying in the next several weeks. I post this for comment, especially from Energy Trust. Is there a simpler way of doing this? Don't we agree insulation and support means should not hang down, with danger to the installation, and obstruction of passage? Certainly, infrequent supports must not permit insulation to fall out of contact with floor sheathing. Most crawl spaces do not have an excess of headroom.
