Should you DIY?
Are your windows right for SLIPs?
SLIPs are a great product for square/rectangular wood windows. This is due to the SLIP needing to cover the whole surface of the original window glass. SLIP extrusions that need to be fastened to the sash are 3/4″ and screw in at a slight angle. Its recommended that you have a 1″ space on the exterior sides of your putty glazing.

Do You Have The Skills?
Woodworking and technical skills are needed to successfully take on this project. Installing SLIPs on a fixed window is rather easy. Installing SLIPs on a single hung or double hung window is a lot more complex and takes much more steps.
Fixed windows– Installing a SLIP™ on a fixed window in a simple job and involves cleaning and prepping the window before applying the
Operating Casement Windows (including french casements, awning, hopper)- If Weatherstripping is not needed this will be similar to the fixed window install. We do recommend weatherstripping to get the benefits of the whole SLIP system by using our provided kerf in weatherstripping. Doing this involves removing the sash, kerfing 4 sides of the operating window. The process may also involve measuring and planing the sides of the sash.
Double/Single Hung Windows- These are the most complex and have the most steps for successful installation. Installing on this type of window requires disassembly of the window. Steps involve removing the sash, kerfing, channel routing, stringing the balances, caulking and more.
Do you have the time?
Installing SLIPs on casement windows can take 1-2 hours per windows. Installing SLIPs on a single hung or double hung can take approximately 3-4 hours per window.
Working on any home improvement project requires a certain knowledge of safety. Tool safety, ladder safety, proper PPE, and more. You must make sure you are aware of the hazards when taking on a home improvement project.
If your building was constructed prior 1978, you can assume lead paint is existing on the windows. Working around lead paint takes proper precautions. If you do not know how to work around lead paint, pleas reevaluate if you would like to take on this project. When doing a project we try not to disturb the lead paint, but it can happen on occasion. Please call 1 (800) 424-LEAD  to talk with a specialist.
Double hung Sash Operation
Yes you can use ropes! The reason we offer balances when ordering the SLIP™ Kit is because there are more unknown variables to calculate when using ropes . Also, shipping dense lead weights increases shipping costs dramatically. Here are a couple things to account for when using ropes.. CLICK HERE
