There are 5 Series of double hung vinyl windows available from Thermal Windows and Doors that we install for our Chicago clients. They all carry Lifetime Vinyl Warranty and additional limited warranties that apply to their particular components and features.

What’s characteristic to double hung type windows is that they have double sash in a single window frame. This allows for both, top and bottom, to slide independently up or down providing ventilation along its top or / and bottom edge.

Another important feature is tilting of sashes which make cleaning and maintenance extremely easy.

Although double hung windows have many applications and home owners install them everywhere, the most common placements are nearby the patios or decks and pathways.
