Glass Bottle or Paper Bag?

If you wanted to keep something for 50 years would you keep it is a paper bag or a glass bottle?

This question came from a recent architect training I conducted in New York. I was engaged in a conversation about wall systems and sustainability with this group and the discussion moved to durability in relation to sustainability.

I posed that question and the response was a glass bottle. However, a case can be made for both.

Many of the passive energy saving measures we employ in our buildings can only be accomplished effectively during initial construction.  As an example; it is very difficult to add insulation to side walls over time because the cavity is designed, constructed and closed in.  If you want durability and longevity you better be building something upfront that will last at least 50 years.

To that end, do not employ difficult to replace materials that are not intended to last as long as the wall you are building. If you haven’t figured it out yet we were talking about different types of insulation.

If you can’t see it, inspect it, or fix it, you had better be sure it’s going to be around longer than you are.

Your thoughts are always welcome.
