Vinyl Windows Built for Comfort and Lasting Performance
Timeproof USA installs ENERGY STAR certified vinyl replacement windows with custom sizes, styles, colors, glass packages, hardware, and trim—backed by the TimeLock installation standard.
Why choose TimeLock windows
Performance, durability, and design flexibility
TimeLock windows combine a premium vinyl compound with construction features designed for comfort and long-term use. Each window is built to order, so your project can reflect the needs of each room and the look of your home.
Energy-focused construction
ENERGY STAR certified windows include thermal performance features such as ComfortLock Technology insulation and TimeLock Thermal Reinforcement.
Low-maintenance vinyl
The premium vinyl compound is engineered to resist rotting, cracking, pitting, corroding, and peeling, and does not need painting.
Custom-built for your home
Choose window size, style, interior and exterior colors, hardware finish, glass package, grids, and trim for a more tailored result.
Window options
Choose the shape and function each room needs
A replacement project does not have to use one style throughout the home. TimeLock options include double hung, sliding, picture, casement, awning, bay and bow, garden, and architectural shapes. Double hung windows tilt inward for cleaning, while casement and awning styles provide control over ventilation.
A window system made to order
A consistent installation standard behind every window
TimeLock is the installation standard behind the Windows & Doors System, not an upgrade tier. The documented process includes professional installation, organized project management, detailed craftsmanship, and thorough cleanup. Every window is built to order so style and performance choices can be coordinated with the room, opening, and exterior design.
Before selecting your windows
Match the window to how you use the room
Consider how each opening needs to operate, how much ventilation or privacy you want, and whether easy cleaning is important. Double hung windows tilt inward, picture windows emphasize the view, and casement or awning windows offer different approaches to airflow. Your choices can also include double- or triple-pane glass, privacy styles, tints, grids, hardware, and trim.
