Window Restoration
Transform Your Single-Pane Windows with SLIP™
Drafty Windows? Poor Energy Efficiency?
Upgrade to modern standards with the Slim Line Insulating Pane (SLIP™) - a cost-effective solution to enhance your home's comfort, energy efficiency, and style without replacing your windows.
SLIP™ adds a tempered glass pane to your existing sash, simulating double-pane windows while preserving the charm and value of your original wood windows. Its sleek, low-profile frame integrates seamlessly into various window styles, including single-hung, double-hung, casement, and picture windows. Unlike storm windows, SLIP™ is a permanent, hassle-free solution.
Why SLIP™?
● Energy Efficiency: Comparable to insulated glass units without the risk of fogging or
seal failure.
● Cost-Effective: A more affordable alternative to full window replacement.
● Historical Preservation: Retain the original look and functionality of your windows.
● Durable Design: Solid construction with minimal maintenance needs.
● Flexible Options: Interior or exterior installation with clear, obscure, or low-e glass.
Proven Performance
Energy tests by the University of Oregon show that SLIP™ reduces window energy costs by 72.9% on average:
● Single-pane windows: 454 therms and 474 kWh/year
● Single-pane + SLIP™: 123 therms and 129 kWh/year
