Ondura is also recognized by the EPA as an Environmentally Preferable Product, making it the greenest roofing material on the market. Ondura's very construction makes it different and makes it a superior roofing and siding material at the same time. Its corrugated design enables it to be both lightweight (18 lb. per sheet) and strong, while its total asphalt impregnation means it outlasts most other roofing (including metal). Ondura is easy-to-cut and install, even over existing roofing like metal or asphalt shingles (up to 2 shingle layers).
Ten new grand juries are impaneled for each of the January and July Terms, with five serving for three months. Each grand jury meets for two scheduled days a week at 1201 Franklin, 3rd Floor, Houston, Texas 77002. The grand jury's workday can last as long as a regular work day, but is often shorter.
Thereafter, in the event the court excuses one of the initially selected jurors, it may then impanel the alternate. Courts in every federal judicial district empanel grand juries of 23 persons. Federal grand juries generally serve for 18 months. The 18 months begin to run from the date of empanelment. However, the district court may discharge the jury earlier, or extend the jury's service six additional months, if it finds the extension to be in the public interest.
