How to Seal a Window: Tips From Lincoln Tech
This is Mark Urscheler. I'm a certified Master HVAC educator here at the Mahwah Campus of Lincoln Technical Institute. We're here today to show you some ways to weather-proof your home, make it feel more comfortable, and reduce energy loss from your house in the wintertime.
One of the greatest places that homes lose heat is from windows. That's what we're going to be talking about today. I'm going to show you some simple steps any homeowner can do. One of the simplest is any type of weather stripping designed for windows, that you can buy at any home center hardware store. Basically, it's all a matter of just replacing the weather stripping that has worn out or was possibly never on your windows (if they're old enough windows).
Any place the window meets the window frame, you're going to install thin, little pieces of weather stripping. They're typically adhesive-backed, so you just have to cut the length you need, and they will stick right to the frame. Now when the window comes down, it seals that space between the window and the window frame, and prevents any air from leaking in there.
When we come back, I'm going to show you a window installation kit which we will install on this window, which is another method of sealing up the whole window.
An Alternative Method of How to Seal a Window
Another way to seal the entire window, you've probably seen these type of window installation kits that you can also buy in any home center. You can see them online hardware stores. Really easy to do – the kit comes with everything you need.
It's a clear cellophane plastic. There is two-sided tape that you then run along the edge of the house. I've already installed them on the top and on the bottom. All you do then is stick the cellophane to that tape. Once it's all tightened up, you run the double-sided tape round all sides and run this. You take a hair dryer or a blow gun, you heat it up, it expands, tightens up, makes it nice and clear. You can't even see it, but it will prevent any wind from blowing in and make a nice, tight seal.
