My home turned into a freezer— and the culprit? ❄️😐 Hidden gaps, missing insulation, and a lazy install job 🛠 With zero skills but no patience for the cold, I ripped it apart… and what I found was a nightmare 😱🥲 The fix was messy, but now warmth wins 🔥 Read the details in the article below 👇
Plastic windows don’t always mean there won’t be any drafts. The window sill itself can get quite cold, often 10-12 degrees lower than the room temperature, making the whole space feel chilly.
At first, I hoped to solve the problem without spending extra money, but that didn’t work out. I ended up buying a silicone sealant and used it to cover all the joints and any visible gaps.
It helped a little, but the room was still cold. I had no choice but to take more serious action, even though I had no prior experience or skills in this area.
About a year ago, after the windows were installed, I noticed several gaps under the window sill and filled them with foam. I wasn’t sure what was happening on the outside, but I focused on what I could fix inside.
Luckily, removing the sill turned out to be easy. I simply unscrewed two self-tapping screws, lifted it up, and took it out.
To my surprise, there was barely any foam underneath, leaving a lot of empty space below the plastic frame.
That’s when I saw where the cold air was coming from. There was a gap of at least two centimeters between the inner and outer wall. It seemed like insulation should have been there, but it wasn’t. On the sill itself, I found only a single strip of foam, which looked more like part of the installation rather than proper insulation. It had to go.
I scrubbed the surface with a stiff brush and washed away any dirt to ensure better adhesion.
Using a broom, I cleared away loose cement and shook the debris into the gap. Then I vacuumed everything thoroughly.
After that, I bought some installation foam and started working. I filled all the empty spaces under the frame and sealed the gap between the walls, making sure to take care of the exterior as well.
Maybe I used more foam than necessary, but I was really happy with the outcome.
The sill fit back perfectly. The screws held everything in place, and while there was a bit of foam visible on the sides, it wasn’t a big deal.
Three days have passed since I finished, and now the window sill is no longer cold. Its temperature is almost the same as the rest of the room.
