Reliable 5700 Single Hung Windows
Our most popular window — all-welded vinyl, energy-efficient, and built to order in Houston.
About the Single Hung window
A single hung window has a fixed upper sash and an operable lower sash that raises to open. It is the most common window style in Houston homes — clean, classic, and budget-friendly, with only one moving sash to maintain.
The Reliable 5700 Single Hung is built to order in our Houston facility on the VEKA platform: an all-welded vinyl frame and sash, a sloped sill, and a brickmold exterior that gives it the finished look of a wood window. It carries a Grade 50 structural rating and an AAMA R-PG50-H performance rating, and it is available with insulated Low-E glass for the energy efficiency Houston summers demand.
