Another successful client passing NFPA 285! Great work Team!
Ok Manfred Kehrer let’s see what kind of monster you can find out of these! Another successful client passing NFPA 285 which correlated nicely to our small scale testing that Built Environments team previously did our lab. When you have an idea of what to expect prior to testing it makes the day so much less stressful! #firetesting #nfpa285 #science

Jarrett Davis is at his happy place this week! Big NFPA 285 and ASTM E119 fire testing going on at the ICC NTA, LLC
Back into the frying pan and heat with another client this week. Doing an interesting #NFPA285 and #ASTME119 floor assembly for another client. Always better to combine and coordinate testing whenever possible. Built Environments

Fact or fiction? Coatings cured for 90 days have greater water penetration resistance than those cured for 7 days. Coatings typically have both an evaporative phase and a curing phase. The former involves evaporation of the carrier solvent such as water. This is the phase installers are most concerned with as it generally determines a tack-free surface and the progression of work. In contrast, curing involves various chemical processes that impart characteristics such as hardness, adhesion, and potentially water absorption. Some coating manufacturers claim vastly improved resistance to water penetration when coatings are cured for extended periods, specifically 30 to 90 days. I was suspicious, but it offered an interesting hypothesis for rogue testing. Here, I show water content of gypsum panels coated with three different acrylic-based WRB coatings. The coated panels were aged for 7 or 90 days and then exposed to water ponding for five hours. When using this method, we see that water resistance doesn’t change appreciably over time. If the coating absorbs water, it does so equally well after suitable dry times as it does with extended cure times. While factors such as hardness and adhesion are likely improved, water absorption isn’t.

The discussions is going on! Ask your questions and make your remarks to M. Steven Doggett, Ph.D. and we might just feature your comments in our future discussion videos!
Does a 1.5 mm gap drain as well as a 10 mm gap? The short answer is yes. Gap size actually matters less than other factors such as water application rate, water absorption, drainage patterns, drainage distance, and gap continuity. This is especially true when assessing drainage efficiencies in accordance with ASTM E2273. The brainchild of the EIFS industry, this standard demonstrates how a lot of water poured down an orifice results in a lot of water being released at the base of the wall. In other words, this approach measures displacement more than it does free drainage under real in-service conditions. A truer measure is gained by assessing drainage at lower application rates. This graph shows drainage efficiencies of 10 mm and 1.5 mm gaps under standard flow, low flow, and high flow conditions. We tested two full-scale walls for each flow and gap condition. The 10 mm gap was achieved with HDPE furring strips, installed vertically. The 1.5 mm gap employed a commonly used drainage wrap. Under all three flow scenarios, the 1.5 mm gaps achieve the minimum criterion of 90% efficiency. Higher flows result in higher efficiencies, lower flows result in lower efficiencies. So, less water - not more - is the greater rigor.

I can feel the flames from here! See the NFPA 285 test in action.
Ever wanted to see what an NFPA 285 test looks like? It is definitely one to remember and something that few get to see in person. This test is used to simulate a multi-story building with an exterior wall that has window opening placed into it. The fire is initially started within the room and then an additional burner is placed at the window header to accelerate the initial flame spread for the test at a controlled. The photo below was taken during a burn test ICC NTA, LLC in Bryan, TX a few months back for a client with my friend Joseph Briski at the fire lab. If you want to see the full video, please check out the initial comment below this post (welcome to algorithms) and while you are there please like and subscribe to the Built Environments channel for more video updates. But we plan to do additional videos and follow up, especially on fire. So what questions about NFPA 285 that weren't answered and you still have? Leave them in the comments below.
