Window Restoration
Drafty Windows? Lack of Energy Efficiency? Update and insulate your windows to modern standards with this reliable long term solution. Introducing the Slim Line Insulating Pane | SLIP™.
Over 20 years of experience restoring wood windows has made this product come to life. Modernize your single pane Windows and make your home more comfortable, with the SLIP™ (Slim Line Insulating Pane). This update is an innovative and cost-effective way to retain your original, and valuable, wood Windows, while making them more efficient, saving you money, and enhancing the comfort of your living space.
SLIPs are designed to update single-pane wood windows to modern standards of efficiency and operation. We have made it possible to add an additional 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, picture windows and more. This modernization is a long term solution that does not seasonally need to be reinstalled.
A SLIP™ will dramatically boost insulation power in your windows and will bring great savings to your month to month energy bills. In terms of insulation power, SLIPs have been tested and are comparable with insulated glass units. However, unlike true insulated glass, SLIPs will not fog up and succumb to seal failure and require periodic glass replacement, meaning lower future maintenance costs.
SLIPs are highly effective, well designed and well-priced, giving you superior value when compared to alternatives. SLIPs have a sleek look and feel with a low profile that blend 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.
When installing SLIPs on doublehung windows, the weight of the balances needed for window operation may be adjusted. This can be done simply by adding weights into the weight pockets when operating with ropes and pulleys.
Hidden balances can also be fitted to the window if a more modern window operation methods is sought after.

PERFORMANCE
Energy testing was performed by the Energy Studies in Buildings Lab at the University of Oregon. Using results on the study, it was concluded that adding SLIP™ to the windows in an average household will result in a cost reduction of 72.9% for the windows.
-Single pane windows…454 THERMS and 474kWh
-Single pane window with added SLIP™…123 THERMS and 129kWh
-Single pane window with SLIP™ and weatherstripping…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.
How to get SLIPs on your windows
The creator and manufacturer of the product, Chosen Wood Window, has been, and still does, install SLIPs on commercial and residential buildings in the Northwest for over a decade.
For people further out who are looking to modernize their windows, we highly recommend our SLIP™ Kit. We assemble, sell, and ship custom made DIY SLIP™ Kits. These kits contain all the custom sized materials that are needed for a successful install. Contractors and handy homeowners are highly encouraged to purchase these kits! We have a full length installation instruction video as well as a tutorial video on how to measure for your custom sized SLIPs. Please visit our YouTube page Here.
Based on the energy modeling that we did for the building, including live mock ups, the study showed that the SLIPS were very close to the energy performance of the IGU option, and given the lower cost the decision was made to go with the SLIP system. We are now three years into occupancy and have had no issues with the windows. The SLIPS are very unobtrusive, and we were able to save hundreds of historic windows and still met our stringent standards of energy performance that exceeds Oregon State Code."
