A modern replacement system
Why Homeowners Replace Aluminum Windows
Older aluminum windows can contribute to drafts, condensation, noise, and rooms that are uncomfortable in changing weather. Timeproof USA replaces them with custom-built TimeLock vinyl windows featuring reinforced frames, precision-welded corners, insulation, and weatherstripping designed to help manage air, water, dust, and noise.
ENERGY STAR certified
TimeLock windows are ENERGY STAR certified and engineered for thermal performance, with ComfortLock insulation and TimeLock Thermal Reinforcement.
Built for low maintenance
The premium vinyl compound does not need painting and is engineered to resist rotting, cracking, pitting, corrosion, and peeling.
Custom-built for your home
Choose the window size, style, interior and exterior colors, hardware finish, glass package, grids, and trim.
Options for comfort and privacy
Double or triple pane glass, warm-edge glazing, sound-dampening features, privacy glass, tints, and internal grids are available.
What your replacement includes
A Better-Fitting Window System
Replacing aluminum windows is about more than changing the frame material. TimeLock windows use welded frame and sash construction, precision-welded corners, barrier-fin and bulb-seal weatherstripping, and ComfortLock Technology insulation. TimeLock Thermal Reinforcement is designed to provide better thermal performance than standard aluminum reinforcement while staying comfortable to the touch in both cold and heat. Standard fiberglass screens are included, with upgraded stainless steel mesh and hardware-free spring-frame options available in select markets.
Design around your home
Customize the Look, Glass, and Function
Every replacement window is built to order rather than selected off the shelf. Choose from double hung, sliding, picture, casement, awning, bay and bow, garden, and architectural shapes based on how each room is used. Interior and exterior colors, decorative hardware, glass packages, grids, privacy glass, tints, internal blinds, decorative glass, and factory-fit trim give you practical and visual options for each opening.
