STEP 7: ENERGY SAVING R1 PANEL INSTALLATION
•
After the basic installation is complete, you'll want to install the energy saving R1
panels which will ensure that your unit meets the Energy Start standard for effi-
ciency. This will help prevent drafts coming in through the window filler panels by
adding a layer of foam insulation.
•
Start by measuring the width of your finished filler panels on either side (W) and
write it down. It is important that you wait until you're completely done the instal-
lation as the width will vary depending on how you installed the unit.
•
Remove the R1 Foam seal from the package and cut to the measurement of "W" as
recorded in the previous step.
•
Install one side. Note that there will be an extra 2-3 millimeters of material in
length (height) so that you'll be able to tuck it in under the window filler panel
frame to hold it in place. Repeat for the second side.
•
Note the finished installation.
