A Better Replacement for Metal Windows
Replace aging metal windows with custom-built vinyl windows engineered for energy performance, durability, and a finished look suited to your home.
Built for comfort
Move Beyond Aging Metal Frames
Older metal windows can contribute to rooms that feel less comfortable and may allow more draft, noise, or condensation than you want. TimeLock replacement windows use reinforced vinyl frames, precision-welded corners, ComfortLock Technology insulation, and TimeLock Thermal Reinforcement to support thermal performance without relying on standard aluminum reinforcement.
ENERGY STAR® certified
TimeLock windows are certified to meet national or climate-zone-specific energy performance standards.
Weather protection
Bulb seals and barrier-fin weatherstripping are designed to help keep out air, water, dust, and noise, including across uneven surfaces.
Low-maintenance construction
Premium vinyl is engineered to resist rotting, cracking, pitting, corroding, and peeling, and does not require painting.
Built to order
Choose the Right Replacement Configuration
A metal-window replacement project can be tailored to the way each room functions. Double-hung windows tilt inward for cleaning, sliders provide straightforward operation, picture windows emphasize the view, and casement or awning styles offer ventilation control. Bay, bow, garden, and architectural shapes can add different proportions and functions where appropriate. Product and service availability varies by market.
The TimeLock standard
Installation That Covers the Details
TimeLock is the installation standard behind every window project, not an upgrade tier. It includes professional installation, organized project management, detailed craftsmanship, and thorough cleanup. Each replacement window is custom-built around the selected size, style, color, hardware finish, glass package, and trim.
