How Do You Know If A Wall Cavity Is Full When Injecting Spray Foam?
If you’ve ever had to plug a charger into an outlet behind your dresser or apply sunscreen behind your own back, you know the struggle of not being able to see what you’re doing. So how do insulation installers do it? The beauty of spray foam is that you don’t need to tear down your drywall to install it, but you might want to know how these experts know when the wall cavity is filled. Foam Bear Tampa is about to let you in on our little secret so you know what’s going on when you hire us for premium spray foam installation near you!
Starting Things Strong With the Prep Work
To be able to fill a wall cavity with spray foam, some preparations need to be made for things to go smoothly. First, the wall needs to be clear of any obstructions, including old insulation. When there’s old insulation in the way, the cavity won’t fill up properly no matter how talented the installer is. If the obstruction can’t be removed, it’s possible for the installer to drill above and below it to surround it with foam instead.
You’ll also need the right type of foam for the cavity to be filled up all the way. Both spray foam and injection foam are capable of fulfilling this task, but you may want to know the differences between the two foams first since they have different consistencies (thus, different results). We highly recommend spray foam for its innovative use in forming around practically any obstacle.
As for the type of spray foam that’s best for filling wall cavities, both open-cell and closed-cell get the job done. However, closed-cell foam will provide better insulation with a higher R-value of 7.
The Hose Tells All! Listen Closely…
Insulation experts use industry techniques to install spray foam without removing drywall. They open up access to the wall’s cavity by strategically drilling holes into certain spots that will be used to guide a hose or nozzle through. As they let the cavity fill up, they listen closely to the wall and the hose. There will be audible signs giving away the progression of the foam, albeit subtle. Being able to pick up on these little indicators and acting accordingly is a talent that requires special training to pull off with accuracy.
The Cavity Is Filled. What Now?
After the wall cavity is filled, your installer will wrap things up by closing off any holes that were made in the process. The holes are plugged, the siding is put back in place, and the foam will harden and cure in a set amount of time. Once the curing cycle is complete, your new spray foam insulation will be officially ready to start doing its job in insulating and protecting your property!
