Tvitec wins the 2018 Isolar Award for eco-efficient glazing in a project in Washington DC

ISOLAR GLASS, one of the main European groups of independent manufacturers of insulating glass, has awarded the Spanish company TVITEC SYSTEM GLASS the Most Representative Project of the Year Award for the glazing work at 1100 15th Street Midtown Center in Washington DC. This complex is one of the reference projects of the León-based company in the capital of the United States.


From its factory in Cubillos del Sil, very close to Ponferrada, Spain, TVITEC supplied more than 22,000 square meters of diverse eco-efficient glass products to convert the former headquarters of the mythical Washington Post into a modern commercial and office complex, which will also host the headquarters of the American credit institution Fannie Mae. The 2018 Isolar Award for the most representative project was presented to a TVITEC representative during the annual meeting of the German insulating glass brand.

The award will be extended to the main actors involved in the project, especially in relation to the execution of the façade. In this case, the prestigious architecture studio SHOP ARCHITECTS, carpentry and building envelope specialists Oldcastle Building Envelope (OBE), and the main contractor, the American Clark Construction.

TVITEC manufactured nearly 5,000 double-glazed units for the Midtown Center with the addition of GUARDIAN and AGC selective layers to prioritise eco-efficiency both inside and outside the complex. The Spanish architectural glass processing company added its 4.0 tempering and lamination technology to ensure the required safety and sound insulation for this demanding project.


Midtown Center, in the heart of Washington, consists of two blocks of 14 floors that communicate with each other through a series of bridges that connect the two wings over a large central courtyard. The exclusive façade, designed by Shop, is a curtain wall with panels in which the glass is combined with copper panels and aluminium extrusions through 40 different geometric joints.

The International director at TVITEC, David López, was pleased with the award, which he dedicated especially to the American clients who trusted and continue to trust in TVITEC. The company is already developing other emblematic building projects in Washington, as well as in other American cities like New York, Boston, Dallas and Miami. Some of these are super-tall skyscrapers that exceed 300 meters in height.

The director of manufacturing, Recaredo Prado, who was in charge of collecting the award at the annual meeting of ISOLAR, thanked the jury and all the European partners of ISOLAR for this distinction, which highlights the international, sustainable and high quality nature of TVITEC’s glass solutions.
