Drafty Windows?
Lack of Energy Efficiency?

Are you a homeowner living in a vintage house or apartment? 

If so, are you tired of your non-functioning, uninsulated, drafty windows? It’s time to Update!

Introducing
The Slim Line Insulating Pane | SLIP™

Owning an old home can sometimes be challenging. While you love the charm of your vintage home, it can be costly and time-consuming to manage.

Some of the challenges of owning an old home can include:

  • Loss of heat and air-conditioning through leaky windows
  • Water damage and leaks around window frames
  • Difficulty installing and operating bulky storm windows
  • Single pane windows are ineffective at reducing outside sound
  • Expensive to maintain vintage windows
  • Replacing windows can affect original charm and value.

Did you know that the average home can lose up to 30% of its heat or air conditioning energy through the windows? SLIPs are designed to maintain the beauty of your original windows while protecting you from the elements and increasing the insulation of your home. In terms of insulation power, SLIPs are similar to insulated glass conversions. Another key aspect is that SLIPs will ensure your window sash remains fully operable, without any need to open two sets of windows as you get with many types of traditional storm windows.

Adding SLIP™ to the windows in an average household will result in a cost reduction of 72.9% for the windows.

Average Energy Consumption Associated with Heat Gain/Loss of Windows at a Typical U.S. Household:

  • Single pane windows…454 THERMS and 474kWh
  • Single pane window with added SLIP™…123 THERMS and 129kWh
  • Single pane window with SLIP™ and weather-stripping…93 THERMS and 97kWh

A therm is a unit of measurement of energy (more specifically, thermal energy). The therm is used to measure gas consumption as well as consumer cost.

The overall U value of a test window wall assembly reduced 61%, from 0.44 to 0.17 BTU, from the base case to the final configuration. The U value reduction from baseline for each improvement is as follows: 18% for weather-stripping, 15% for wall insulation, 26% for SLIPs, and 28% for the double pane.

how does the slip work?
The Slim Line Insulating Pane is a sleek, low profile addition to your Single Pane Window
Single Pane Upgrade SLIP

We have made it possible to add a TEMPERED pane directly to each sash overlaying your current glass setup. This essentially turns your single pane window into a simulated double-paned window. The frame of the SLIP™ is an attractive, low-profile, pressed metal extrusion.

This simple solution can rejuvenate Single-hung, double-hung, casements, and more. This modernization is a long-term solution that does not seasonally need to be reinstalled.

SLIPs are highly effective, well designed, and well-priced, giving you superior value compared to alternatives. SLIPs have a sleek look and feel with a low profile that blends into the sash; you’ll hardly know they are there.

Another key aspect is that SLIPs will ensure your window sash remains fully operable, without the need to open two sets of windows or remove any components as you sometimes get with storm windows or inserts.
