Energy Testing

SLIP vs Replacement Windows:

Your original vintage wood windows are made with quality old growth hardwood material. This material has lasted the test of time and wood material like this just inst readily available anymore. Your original vintage wood windows are a valuable asset to your home, they just need to be modernized to current standards of functionality. Not to mention your originals windows match the style and character of your home/building. We always recommend to update your original windows instead of costly replacement windows which simply don’t hold up.

SLIP vs Conventional storms:

There are many valuable features that a SLIP has that a conventional Storm wont. One of the biggest values is how our SLIPS product looks compared to a storm window. We started producing SLIPS as an alternative to conventional storm windows in an effort to not take away from the look of a vintage window, and also give you increased protection from the outside elements and increased insulation value as well.  Storm windows can be big, bulky and a nuisance to opening your window. Slips you’ll hardly notice they’re there.

Q: Can I Install SLIPs myself or do I need an installer?

A: If you are have the appropriate tools and knowledge of basic use you can install the SLIPs yourself. Otherwise we recommend you use a certified installer.

Q: Are SLIPs paint-able?

A: Our SLIPs come coated with an attractive primer that allows for painting if desired.

Q: Do I need to fill out paperwork before putting them on my historic home?

A: It depends. If Federal monies are attached to the property then any changes to the property have to allow the Advisory Council on Historic Preservation (www.achp.gov) to comment on the project. Otherwise you are free to have our product installed. Our product was intended to keep old wood windows vs replace them… If you have any doubts contact your local SHPO

Q: Do I need to remove my SLIPs in the summer time?

A: There is no reason to remove the product. Once the SLIP installed it blends in and becomes part of the window itself.

Q: Should I get my windows painted before getting SLIPs installed?

A: SLIPs main purposes are for function, protection, and energy efficiency. If you want to add to to the aesthetics of your windows we recommend they do get painted prior to having SLIPs installed

Q:How do I clean SLIPs?

A:  Do not use a power washer to clean SLIPs.  Power washing SLIPS could force water into the interior window glass through vent holes, causing water staining on interior glass surfaces. If water does get in between the SLIP and the original glass (a rare occurrence), unscrew SLIP, clean glass, and reinstall. The glass is tempered and soft. Use a mild soap and a soft cloth to clean. Abrasive or rough products of any kind can scratch the tempered glass. Do not caulk or paint heavily around the SLIP, it could block the vent holes and cause fogging. If sweating is an issue, more ventilation is required.

Q:Can a SLIP go on a door?

A: Yes, a SLIP can be applied to doors with the same effect as a window

“My second experience was on Straub Hall (1929), where again the windows were removed, striped and repaired as needed, and in this instance were outfitted with the SLIPS. 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 IUG option, and given the lower cost the decision was made to go with the SLP 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. “

“We were able to keep our original windows from 1936. They are now operable again and insulated. We were able to take our storm windows off. This is a valuable addition to our home.”

Constance Crass, Homeowner

“I couldn’t be happier with your service and products. I have recommended you to our neighbors. Thanks again”

Dan Magner, Homeowner

“Very pleased with the windows and the improvement in comfort (no longer needed to wear a hat inside in the winter) after they were installed to all my windows. I am very happy with my choice to use your company to upgrade my single pane windows (1904 Bungalow). ”

Lisa Wisniewski, Homeowner

“I’m glad they are around as a resource for old windows.  I have always felt keeping the old windows with the new window slips was the best way to go in order to maintain our beautiful wide window sills and have insulated windows.”
