Expert Guide to Fluid Applied Window Installation

Glad you have continued making videos about new products and techniques! Thank you!

hey matt! are vertical hairline cracks in newer construction for a home in the foundation walls normal?

where is the best place to buy the R-guard system?

How does this differ in a flangeless 'european' window install?

What is the failure mode for this fluid applied flashing. Have you seen a properly fluid appled sealed window fail?

Fluid applied. Cmon..

Looks like you folks mis-spelled the word “Applied” on the thumbnail image.

Seems like taping is faster and more full proof, no? Am I missing something? Seems like a solution to a problem that didn’t exist

I think the whole industry is wasting money. Why don't people just use air concrete instead of woid if they spend that much money on wood.

In 20 years when windows need to be replaced, how hard is it to tear it out?

I can see the 119 languages on the label it needs for all the illegals applying it. 😂😂😂

Disappointed, from the title I expected Matt to pour molten glass into the opening and make his own fluid applied window 🤣

Would you ever run a bead where the vinyl fin joints into the fiberglass window for air barrier purposes? Ha, 15 seconds after I wrote this you mentioned the sealant on the interior and exterior from the manufacturer. Ok, assume it's a window that doesn't have the factory applied inner and outer sealant.

I get using it on the floor band where it meets the basement wall but I prefer the tape because those windows are going to have to be replaced one day

Will this product adhere to pressure treated plywood?

The only issues is how firm it is if the header sags will it crack the glass?

not used to a sloppy process from Matt! Everything is usually 100%!

If roofing tar was pink, there would be no need for this pricey sausage stuff

The cost to value is definitely a numbers calculation every builder should do before committing to this product. We use it, will continue to use it. But it’s significantly more expensive than “Tape”. When the system is explained to an owner, you have to be able to justify the cost difference.

I wonder how well this product will stand up to time. When the house settles a bit will it flex or will it crack? Especially on the sides with direct sunlight.

Matt is the rough opening bottom sloped?

Nope. Let’s see how it performs over ten years. I don’t much care for tape either, although it has proven itself over time. I’m old school and I prefer metal flashing and an isometric caulk. I have been in the building trades for 40 years and I am wary about new products as they can be tested in the lab against wind and water. The one thing which cannot be simulated is the passage of time.

What's a pirates favorite fluid applied flashing system? Rrrrr guard

I think the tape isolates stresses between the house and window. Also seems easier. Probably equal performance. Just faster with tape.

How do you decide which window system to use? Your videos highlight Zip-based, Prasoco. How do I approach a prospective builder to learn what window flashing system to use? What about aluminum cap flashing?

I feel like tape will lose its grip after a few years. A flexible rubber material sounds like it will last longer. Is it cheaper to use OSB and this spray on coating vs Zip sheeting?

Seems must slower than peel and stick.

OSB interior walls???

Having to mist the surface before applying the sealant on a dry day is a clear point of failure in the future for many builds since there’ll be many many installers that skip that step. That absolutely sucks.

Matt
What kind of coverage can you expect with the Cat 5? I didn't see anything giving a range on the website. Just trying to get an idea of how much I'll need to see what kind of cost I'm looking at if I use it.

That sequence along the right side of the window flange really shows how easy it is to mess up with this stuff. The very experienced installer had to do it three times with Matt acting as quality control. I’ll take Zip tape over fluid applied every time. Still have to install it correctly, but there’s less opportunity to screw it up. Given that this is a SIP home (if I heard correctly), fluid applied probably made sense since the WRB is fluid applied—probably required for maintaining the warranty from Prosoco.
