Being a âSettlementâ currency is not quite the same as being a âReserve Currencyâ like the dollar, but it a major step in that direction. It is, in fact, a very large step. Which currency large international trades are done in matters.
There are approximately 33.33 square feet in a bundle of standard composite shingles. A square is a 10-foot by 10-foot area and requires three bundles of shingles for coverage.
16 sawn shingles usually cover 25 square foot per bundle at 5 1/2 exposure, which is the maximum allowed for roofing applications. You can expose less of the shingle to change the appearance, but you will get less coverage per bundle that way. If I had to guess, this is what I would think you are talking about.
