A Simple Guide to Insulating Windows

Lancaster Heating

Are you looking to save money on your home heating costs this winter? Start
by properly insulating each window in your home. Those that do not properly
fit their frames will create a draft that will allow your home's heat
to escape. Here is a step by step
guide:

Exterior Insulation

Mother Nature and her moodiness can create exceptional wear and tear on
the exterior of your home, including windows and doors. Before you start
insulating the interior of your windows, make sure you seal their exterior first.

  • You want the caulking that you're going to apply to dry properly, so
    pick a day where there is no precipitation and the temperature is above
    45 degrees. Start this maintenance early enough in the day to allow for
    as much drying time as possible while the sun is out.
  • Grab a putty knife and begin scraping the edges of each window. This will
    remove old, worn caulking and paint to allow more room for the new sealant.
    Afterward, wipe the edges clean of any residue.
  • Use a caulking gun filled with no-drop, exterior grade silicone caulking.
    Apply the caulking in a continuous motion around the entire window at
    a 45-degree angle. Once applied, push in the caulking with your putty
    knife and smooth the edges.

Interior Insulation

Once the exterior sides of your windows are sealed, you can head inside,
warm up, and begin insulating the interior. For maximum insulation (and
savings), you'll need to apply new weatherstripping.

  • If your windows currently have weatherstripping installed, take the time
    to carefully remove it, as this material is usually only good for a year
    or two. Once removed, wipe down the edges of the top and bottom window sash.
  • Purchase new weatherstripping, preferably one of a higher quality so it
    can provide you with better insulation for a longer period of time (three
    to five years). Measure the edges of each window sash, cut pieces accordingly,
    and apply them to the window.
  • If you want to take your savings to the next level, consider installing
    insulated film on your windows. This window film will help retain more
    of your home's heat while also reflecting heat and blocking harmful
    UV rays. Lean towards purchasing a higher quality window film that won't
    lessen the clarity and light of your windows.

Insulating your windows (inside and out) will help your home retain more
heat, saving you money each month when it comes time to pay the bills.
