US Patent And Trademark Office Townhouses

ATAS International Inc.

In 2005, the US Patent and Trademark Office Townhouses were constructed in Alexandria, VA. The architects Skidmore, Owings, and Merrill, from Washington, DC, chose ATAS International Inc.’s metal roofing materials based on a number of criteria.

They determined they wanted a durable and affordable roof system that was compatible with the two office buildings almost adjacent to the townhouses. The building, because of its location, was subject to review by the local Design Review Board. The building was over 400 feet long, and therefore had to resemble much smaller structures. The roof had to provide a different appearance on each part of the building. Existing buildings were historic structures, therefore the townhouses had to have an acceptable appearance to be compatible with these existing historic structures. ATAS International Inc.’s product met all of these requirements.

The buildings were completed with four of ATAS International Inc.’s metal roofing panels. Turner Construction, Baltimore, MD, was the contractor of this project. Prospect Waterproofing Company, Sterling, VA, installed the panels. The four panels were ATAS International Inc.’s Dutch Standing Seam, Castle Top, Permashake, and Opaline. All panels were manufactured with a custom color: champagne gold.

Dutch Standing Seam used in this project was made from .040 Aluminum. This panel was the most used panel in the US Patent and Trademark Office Townhouses. Over 9,600 square feet of this material was used. The Dutch Seam panels had a 19 ¼” width, and were full length. The Dutch Seam panel has a user-friendly seam design that allows for easy installation.

The Permashake panel used in this project was made with .032 aluminum. This project was difficult to access, however the boxed packaging protected the panels and the installstion process, done by a single mechanic, was more productive. 2,900 square feet of this material was used for the US Patent and Trademark Office Townhouses.

ATAS International Inc.’ Castle Top shingle, is a flat diamond shaped metal shingle. The material used in this project was .032 aluminum. Care is required in the layout of this metal shingle. Over 6,200 square feet of this material was used on this project.

Opaline was the fourth panel used. The panels were used for siding. This was an easy installation, and the narrow spacing eliminated oil canning. The material used for the Opaline panel was 0.32 aluminum. Over 1,600 square feet of Opaline was used.
