What is the Right Time to insulate your Windows?


Normally, you should insulate your windows before the arrival of the cold weather.

The majority of these window insulating steps are cheaper.

7 Ways to insulate the Windows from your Apartment


Even as the insulation cannot convert a bad window into a better performance window, it can make so much difference to help you through one or two seasons. Modern, high-quality windows may only need insulating draperies, but possibly not the insulating steps are given below.


Things you’ll need



  • Paint scraper
  • Paint stirrer
  • Caulk gun
  • Sewing machine Needle and thread or (optional)
  • Screwdriver (optional)
  • Putty knife
  • Thermal curtains
  • The draft stopper or draft snake


  • Window film insulation kit
  • Caulk
  • Weatherstripping
  • Spray foam
  • Filler for draft stopper (optional)
  • Socks or fabric (optional)


1. Apply window insulation film


Window film forms an insulating blockade between the inside of your apartment as well as your windows. Kits often include plastic shrink film that you paste on the indoor frame of the window with the use of double-sided adhesive tape. Acting a lot like the krypton gas or argon that accommodates the space between double-glazed window panes, the old air space formed between the film and the window blocks air as well as thermal infiltration. Just heat the film using a hairdryer to shrink it and get rid of wrinkles.


Tip: Window film insulation is not the same as reflective window film. The reflective film adheres straight to the glass while window film insulation needs to stay far from the glass.


2. Set up removable magnetic window insulation


If you want to sometimes open your windows in the winter, your ideal solution is to install removable magnetic window insulation. Magnets can accommodate the insulating vinyl in position so you keep the insulation in position during the cold and leave it off when there is no cold. See how it works here:  

  • Apply many coats of magnetic paint to the trim of the window
  • Measure and cut the vinyl to the size of your window
  • Fix magnetic tape to the vinyl
  • The magnetic tape will keep the vinyl held to the magnetic paint and still be easily removed.


3. Caulk around cracks and gaps


Pick the deal caulk for the internal and external parts of your windows for top insulation. Avoid caulking on the tiny round or rectangular weep holes on the exterior that are working as drainage. You will likely apply about half of a cartridge of caulk for a side of a double-hung window. Remove all old and cracked caulk using a putty knife or screwdriver. Ensure the area is perfectly dry before caulking.


At angle 450, cut off the caulk tube from the tip, dip the tube inside the caulk gun, and pull the trigger to paste the material into the crack. Avoid caulking in starts and stops, but in one motion; this forms a neat, continuous ring of insulation. If you noticed that the caulk is spilling out of the crack, push it back in with a putty knife. Let the caulk cure for 24 hours.


Tip: If this is your first time with caulking, repeat the method on a paper towel before you insulate your windows. This will help you create the pulling motion required to apply the caulk into the crack as it leaves the tube.


4. Use bubble wrap to cover your windows


It may appear unattractive, but bubble wrap is a perfect way to insulate the windows in your apartment. Just spray a mist of water on your clean window’s interior, and hold the bubble surface of the bubble wrap to the misted window. Sealing boundaries with tape may also help keep the heat in but can affect paint when removed.


5. Use thermal curtains on your windows


Thermal curtains contain a special lining that keeps warm air inside in winter and prevents heat during the summer. Thermal curtains also keep light and noise away. Ensure your curtains completely cover your windows so they insulate your apartment windows effectively for winter.


6. Rubber weather sealing


Visit the local store and purchase self-sticky weather sealing strips and then cut them to the same size as your windows. Then, seal off the strips towards the inner corners of the frame. It is a cheap and fast option to insulate your home’s window. Remember that it is essential to replace the strips regularly. You may notice a colored residue when you try to remove old strips. This won’t be a problem if you have it in a plan to apply new ones immediately. Else, you may need to paint the spot.


7. Windows insulation panels


The use of insulation panels is one of the brilliant options. It will be sufficient to install the aluminum frame to the internal side of the windows you currently have in your home. These frames come with a type of weather-stripping at the boundary that is capable of sealing the windows. You can complete the whole job by yourself since instructions and the entire important components for insulation are contained in a panel kit.
