We’re back at another Loctite® 2nd Chance House with Tyler Grace of TRG Home Concepts where he’s demonstrating how to effectively air seal around windows and doors using two specialized products from Loctite®. Both TITE FOAM Window & Door and Pro Window & Door Foam are high-quality, low-pressure expansion foams that won’t bow frames. Tag along to see how Tyler ensures all voids are filled properly using a straw applicator and foam dispensing gun.
Here’s the Transcript
Welcome back to the Loctite® 2nd Chance House, where Habitat is bringing yet another home back to life. Today I’m going to be air sealing around the new front door as well as a soon-to-be kitchen window. For that, I’ll be using two Loctite® products — the TITE FOAM Window & Door, as well as the Pro Window & Door Foam.
For this window, I’m going to be using the Loctite® TITE FOAM Window & Door product. It’s very simple to use; you’re just going to give the can a good shake, pop the top off, install the applicator tip, and then remove the breakaway tab. Next, hold the can upside down, guide the straw into the gap, and then start releasing the product. Don’t be shy when dispensing this product — just use a continuous bead. Any additional foam can be cut back once it’s cured.
Apply with a Dispensing Gun
For the front door, I’m going to be switching to the Loctite® Pro Window & Door Foam, which utilizes a dispensing gun. What I really like about the dispensing gun is it gives you the ability to dial in the output of material to suit your application and your needs.
On the side of the door, we have a long, even gap running up the jamb, and just like with the straw version, I’m going to guide the tip into the gap and release a steady flow to completely seal between the frame and the rough opening.
Because this is a remodel, and Habitat is maintaining the original plaster walls, we have some damage and a wider space at the top. This will all be hidden by trim, but I still want to make sure I get as much foam in there as possible to fill all the voids. Again, don’t worry about applying too much product because squeeze-out is easily cut back after it cures and you’ll be ready for trim.
These two Loctite® products are specifically designed as low-pressure expansion foams, so you’re not going to have to worry about bowing your jambs. And with the Pro Window & Door Foam, we’ll easily be able to seal all the windows and doors on the first floor, and maybe even the entire house.
