A Letter from our C.E.O.

By | Uncategorized

To our valued customers:

I want to offer perspective on the unprecedented circumstances currently affecting the lumber and plywood markets nationwide, as we move into the heart of the season.

-When COVID first impacted the U.S., the lumber/plywood mills severely curtailed operations. This eliminated 50% of the production for 3 months. As demand picked back up, COVID restrictions further impacted the ability of the mills to ramp back up to normal levels.

-2020 demand not only picked back up, but increased due to stimulus monies, etc., so overall aggregate demand was greater than normal. Our projection is that 2021 demand levels will continue to rise.

-Housing starts are increasing, approaching pre “great recession” levels further impacting demand.

-Western lumber species SPF, Hem Fir, and Doug Fir have been severely impacted by Canadian provincial government restrictions on logging, resulting in billions less BFT being imported to the U.S. from Canada.

-Plywood and OSB shortages persist due to production problems that started last year, and have been exacerbated by shortages of plywood out of Brazil, which is a major supplier to the U.S. market.

-Freight has more than doubled in 2021. Trucking shortages are the reality in the lumber and building industry.

Global markets have entered a phase of commodity price increases for just about everything – some calling it a commodity super cycle. Lumber/plywood & many other commodities have seen huge price increases. Shortages of natural resources have developed across the world. Lumber is not exempt from this cycle. It is demanded worldwide and is increasingly competed for by other countries.

Flameproof Company is fortunate to have established relationships for both domestic and imported lumber/plywood. This has helped us to procure and produce consistently. While the prices continue to increase weekly, we are doing our best to offer both availability as well as pricing that lags current replacement costs for at least some period of time. We will continue to do everything in our power to ship product as quickly as possible. We suggest that precaution be taken to allow for added lead times, given the overall state of the market.

Flameproof Companies strongly encourage all of our customers to maintain contact with our offices and your sales representative in order to rid of issues regarding supply. We remain dedicated to doing our best to fill every order as promptly as possible and to communicate pricing in a transparent manner.

We thank each of you for your valued business and look forward to assisting you in any way possible.

Best regards,
Vince Mancini, C.E.O.

Trending In Design (and Durability): ipe Wood

By | Uncategorized

Ipe is a hardwood from Brazil that’s very hard. It’s strength has been compared to that of steel, and most often it needs to be pre-drilled before pieces are connected.

Similar in appearance to rich, warm mahogany, ipe is popular for its beauty and durability. Ipe is FSC certified, making it a smart environmental choice for your outdoor living environment.

Other attributes of ipe wood include:

  • It can last more than 25 years outdoors.
  • Eco-friendly; 100 percent natural wood
  • Mold, fire, weather, and pest-resistant
  • Resists surface scratches
  • Three times harder than cedar
  • One of the densest hardwoods, it sinks in water.
  • It has the same fire rating as steel and concrete, making it a more fire-resistant choice than softwoods.
  • It has high concentrations of tannic acid, which makes it resistant to rot, insects, and fungi. Because of this, stainless fasteners are recommended.

Chicago Flameproof recently worked on a Chicago Riverwalk project that utilized ipe:

Tim Cole has served as Chicago Flameproof’s Inside Sales Manager since March 2018. For more than a decade, Tim worked as a journeyman carpenter for a major general contractor in Chicago, and then in sales for a construction materials vendor, and it was during this time that he first became familiar with The Flameproof Companies. And while it was his past that Tim credits for his introduction to Chicago Flameproof, Tim will be the first to tell you that his reason for joining the company full time in 2018 was all about the future.

“What’s most exciting to me about the company is the future, the R&D side of the business,” says Tim. “Other companies seem to be good with the status quo. We’re not necessarily into changing things, but we are into finding ways to make them better, that will lower costs for customers, and solve challenges that they’re facing in the field through our product innovation.”

As Inside Sales Manager, Tim manages the Chicago area sales team, generating new business and fostering ongoing client relationships and projects. As a manufacturer of fire retardant and preservative treated lumber, as well as a supplier of building materials, Chicago Flameproof’s client base ranges from large distributors to individual local contractors.

“Chicago Flameproof is like a diamond: lots of different facets,” says Tim. “We manufacture fire retardant lumber, preservative treated lumber, we sell to big distributors, and we’re a supplier of building materials for all of our local contractors. Because we manufacture it, we’re able to give customers the best products, fast, and at a better price because we’ve cut out the middleman.”

He continues, “Some local suppliers have delivery hours from 7 am to 3 pm. At Chicago Flameproof, we ask, ‘What time do you want it there?’ We’ll deliver at 2, 3, 4 in the morning if that’s what the contractor needs. Our guys work hard, our guys believe in customer service, and they’ll do anything to make the customer happy.”

Fire Resistant Building: The Cost

By | Uncategorized

With the rise of wild fires impacting towns, cities and major metropolitan areas across the country, the Insurance Industry is finally getting involved to examine building codes as it pertains to fire resistant building materials & construction methods. They’re probably tired of paying out claims for homes wrecked by fires year after year, so apparently someone with some G2 decided to look more closely at the codes, what is being required, and how much those requirements or building codes cost to comply with, and would you believe it, it’s not so bad after all.

I hear the rumbling and grumbling from builders all the time about the building codes and how it’s so expensive to build to meet the new criteria, particularly, fire resistant or fire safe construction. According to a recent article, it actually costs 2% less than traditional construction to build a single-family homes to meet the wildfire codes like that of California. You’re probably wondering how it costs less to do more, right?

It’s all about the assembly.

Let’s consider the exterior wall of your home. That is an important wall. Pretty much, that wall is designed to do a few things: (1) support your house, and (2) protect you from whatever is on the other side of the wall, fire included. Hopefully that wall was built to withstand that fire long enough for you to get to safety. So how can this wall be built to achieve an overall safer home? If your house is like most homes in America, including apartment buildings, condos, townhouses, etc., chances are the frame is wood. Wood is combustible – it will burn when subjected to fire. So in order to protect your wood-framed home, it will require some handy “components” to beef up the assembly.

Fire Retardant Treated Wood = Non-Combustible?

Did you know Fire Retardant Treated Wood (FRTW) can be used in some applications, such as fire-rated exterior bearing walls, that require non-combustible materials? True Story. This does not mean FRTW will not burn, it simply means that the fire treated wood has a delayed ignition time, flame spread and smoke development when compared to raw or untreated framing lumber, and can therefore be used in select applications where typically you’d see something besides wood. More technically, FRTW can often be used in place of noncombustible materials, for instance, exterior walls of Type I, II, III and IV buildings, and in roof structures of Type II and low-rise buildings of Types I construction.

Assembly. Tell me more.

ASSEMBLY = EXTERIOR WALL = drywall, wood studs, insulation, sheathing, exterior facade

As of right now, codes don’t typically require FRTW for single-family homes, but we do have FlameTech Fire Rated Wall Assemblies that can be used in your next job, and we can show you how our system will help you save money too! Now in your bigger Type-III jobs (multi-family housing), FRTW is absolutely used in interior & exterior wall framing. In single-family homes (most commonly Type-V construction) passive fire protection is commonly achieved by using gypsum wallboard of a certain thickness and an exterior facade of a certain type to help withstand fire and protect the combustible wood frame. Yes, sprinklers are an option too. Insulation type is also critical since insulation…. INSULATES. This insulating attribute we so enjoy during the hot summer or cold winter months helps keep wood members from absorbing all that energy from a fire in addition to the more obvious benefits.

Passive Fire Protection = FRTW. It does not require water or electricity to do its job, and can act on it own when subjected to fire.

What happens next?

For the moment, fire treated wood is not often seen in single-family homes. But you’d better believe that those days are coming. The insurance industry will soon begin making a lot of noise that the cost to build the right way with more resistant materials is much more economically viable for our country than to continue building as we are; it’s already begun. We have technology on our side, plenty of history with fire, and folks like us are constantly innovating to bring new fire resistant products to the market to better protect our homes and communities from the danger of fire.

“Insurers, safety advocates and disaster policy experts have urged state and local governments to toughen building codes — a move that’s often opposed by home builders over concerns it will increase housing costs, putting them out of reach of more potential buyers.” Source Article.


Fire Retardant Treated Wood – Know your stuff!

By | Uncategorized

This post features a few different topics of which cause a variety of head-shaking by me on a regular basis. The goal of this post is to provide insight and clarity into some of the key topics associated with Treated Wood, Fire Retardant Treated Wood, Preservative Treated Wood, and all the other important SEO keywords I could use to appear in your broad search results.

We’ll start simple and increase our level of difficulty as we dive deeper.

So ultimately, what is the purpose of fire retardant treated wood?

FIRE RETARDANT TREATED WOOD (FRTW) is designed to resist to flame spread & smoke development caused by fire and/or fire propagation. That is more or less what the building code calls for, but let’s get real folks, it behooves each and everyone of us to learn how to evaluate products for ourselves. As it pertains to FRTW, you certainly don’t have to be the expert, we can help guide you!

BUYERS/CONSUMERS/SPECIFIERS/ – the next time you evaluate any product for use that claims or references any flame spread or hourly fire resistance ratings, be sure to ask for their test results:

Flame Spread classification: ask to see valid ASTM E84 or UL 723 results.

*the IBC requires 0-25 on flame spread index and 0-450 on smoke development.

**the IBC also requires an extended 20 minutes of testing on top of the initial 20 minute E84 test, so make sure the test results reflect that extended test duration.

Hourly Fire-Resistance rating: ask to see valid ASTM E119 or UL 263 results.

*it is critical that you understand HOW to specify/build a tested & certified rated wall assembly to be compliant by code. If the assembly is not built in accordance with the test documents and assembly design, it’s a building code violation.

**Insulation types (density & thickness) along with drywall (type & thickness) are key ingredients (components) in a fire-rated wall assembly. Use the wrong components, and the assembly won’t work.

Fire treated material are used in critical structural applications, such as fire-rated exterior bearing wall assemblies, to allow sufficient time for occupants to escape and first responders to arrive and begin emergency operations. Therefore, we have “fire-rated wall assemblies” that have been tested for some period of time (1, 2, 3, 4-hours) that were designed to resist fire – versus materials that have a certain flame spread rating (Class-A, B, C).


During fire development in a compartment: a room, wall cavity, attic… surface treatment technology plays an important role in fire development, prior to flashover, which include the components of ignition, flame spread, and the release of heat, smoke and gas. ASTM E84 or UL 723 tests the effectiveness of a treated product during these pre-flashover conditions, or more formally, the test is known as the Standard Test Method for Surface Burning Characteristics of Building Materials.

The fire resistance characteristics of treated materials come into play after flashover has occurred, (above 600C) and the fire has entered the fully developed phase. This is where fire endurance is key, and why products/assemblies are tested for hourly fire resistance in accordance with ASTM E119 or UL 263, which is formally known as the Standard Test Methods for Fire Tests of Building Construction and Materials.’

Also, know this… ALL FRTW is required to be Class-A in accordance with (IAW) section 2303.2 of the IBC, but not ALL FRTW has hourly fire resistance ratings ~ fire-rated assemblies.

If you need an FRTW product with a true 1-hr and 2-hr fire resistance rating, you have slim pickings, unless of course your designer rocks out to REM while working the Component Additive Method (CAM)* for determining fire resistance in an assembly. To quickly determine if an FRTW product has been tested for fire resistance IAW ASTM E119 or UL 263, refer to the product’s third-party evaluation report or the Assembly Design documents. Checkout the FlameTech Fire-Rated Wall Assemblies by clicking HERE.

(*CAM embraces the Ten Rules of Fire Endurance Rating by Tibor Harmathy, and you can learn all about that here if you’d like.)

And speaking of third-party research reports….


“I want a Coke.”

“Kid, do you actually want a coke, or do you want a soda?

Funny way to start this section but you’ll understand why shortly… Often, people ask to see an “ESR” when they want to review a new product, or maybe they say to me, “Well, I went on your site and I couldn’t find your ESR so I stopped there…” To be clear – “ESR” stands for Engineering Services Report. It’s a product name for a specific document, just like FlameTech is my FRTW product’s name. We gave it a name because we want consumers to associate our products with our awesome brand. ICC’s Engineering Services did the exact same thing when they turned an internal process, creating evaluation reports, into a profit center.

If an ESR is not required, can I use another type of third-party research report?

Yes. THE REQUIREMENT, as mandated by the International Code Council, is to have a valid third-party research report and coinciding data from a laboratory or inspection service accredited by the International Accreditation Service (IAS).

Prove it.

To make this easier, the ICC provides a website that allows you to go and check out if some lab or test agency has the proper creds and if they can do the kind of testing and inspections that are required by the code. Click this link RIGHT HERE to check out your product’s credibility.


  1. Visit the website:
  2. Navigate to the third box down from the top “Accreditation #” and enter: “AA-647”
  3. Once the results are returned, select the “View Certificate AA-647” link on the left.
  4. View Intertek Testing Services NA, Inc. Scope of Accreditation which includes wall assemblies and fire retardant treated lumber and plywood.

For what it’s worth, evaluation reports are created based on submittal data captured during product testing to demonstrate compliance with certain aspects of the building code. Regardless of which service created the report, they usually begin with a “SCOPE OF EVALUATION” so that you, the knowledge-seeking reader, can understand what was tested and if/how that pertains to the code. The “common properties” listed below are what SHOULD BE evaluated as it pertains to FRTW products:

  1. Surface burning characteristics
  2. Strength reduction.
  3. Hygroscopicity
  4. Corrosion
  5. Fire Resistance

How does the evaluation report process work? Simple. Submit your product’s testing data to the engineering folks to evaluate your treated product for compliance with the applicable codes and standards, pay some $, and if your ducks are in a row, you’ll get a report.

Here’s a dialed-in Third-Party Evaluation Report

Do we need to continue beating this drum? Just know that there is more than one approved method of getting to a desired end state, you have options… that does seem to be the theme of this post. You deserve better, your business deserves better, and so do your customers.


With the continued increase in seasonal wildfires year after year, the building codes are becoming more stringent thereby requiring increased fire protection. Different cities and jurisdictions have even gone so far as to make their own engineering judgments as to what they deem appropriate levels of fire protection in wood-framed buildings. Furthermore, many jurisdictions are open to the use of alternative materials so this should be music to your ears, it is to ours. Honestly, get used to the idea of fire treatments (yes – that is plural) and get cozy with the building codes so you can best assist your outside-the-box thinking customer while also keeping the conmen at bay. I’m not sure about the rest of the Industry, but we’re busy innovating and have much in store for you! Thanks for reading.

“It needs to be PT & FRTW.”

By | Uncategorized

One of the purposes of this blog is to help increase reader’s knowledge and understanding of what we do in the Wood Treatment Industry and how that impacts you and your customer(s) so you can make the best and most informed decisions as it pertains to fire retardant and preservative treated wood products.

What exactly are you looking for?

Lately I’ve been seeing a lot of quotes where customers tell me they’re looking for treated wood that must be “PT & FRTW”. The use of acronyms and deciphering people’s handwritten notes based of their limited understanding of my job is and always will be challenging, but that’s what we have Q&A for, right?

When this situation happens —

I ask something along the lines of, “Are you looking for a combo system or are you asking for code compliant fire retardant treated lumber or plywood?”

The customer usually responds saying, “I’m not sure, I just know the material needs to be PT & FRTW.”

My intent in sharing this with you is to help clarify what the acronyms PT and FRTW represent (where applicable), and to bring some common understanding to these two terms.

Code Speak & Definitions.

What does PT & FRTW mean? For starters, PT could mean a lot of things. Pressure-treatment, preservative treatment, or physical training. Considering my job and probably yours since you’re reading this, we’ll focus on pressure treatment and preservative treatment as possible correct choices.

As for FRTW, it’s crystal clear to me what is being asked for – Fire Retardant Treated Wood (FRTW). Let’s define FRTW per section 2303.2 of the International Building Code (IBC) so we’re all on the same page.

Fire-retardant-treated wood is any wood product that, when impregnated with chemicals by a pressure process or other means during manufacture, shall have, when tested in accordance with ASTM E84 or UL 723, a listed flame spread index of 25 or less and show no evidence of significant progressive combustion when the test is continued for an additional 20-minute period. Additionally, the flame front shall not progress more than 10-1/2 feet (3200 nm) beyond the centerline of the burners at any time during the test.”

With the customer asking for Fire Retardant Treated Wood, this singles out a specific product that has been treated via pressure process to perform in such a manner as detailed by the code. In the world of wood treatment, there are a variety of (a) processes and/or methods involved in wood treatment that deliver a set of (b) benefits enabling treated materials to be used in specified and/or code required application(s).

Briefly, it’s important to note that the AWPA C20 & C27 specification standards of yesteryear have been replaced by the AWPA UCS (Use Category System). Fire Retardants fall under Commodity Specification H. The precise Use Category for Interior Fire Retardant is UCFA and exterior FRTW is UCFB (exterior FRTW). The UCS further defines compliant fire retardant treatment process by “protectants” based off their ingredients providing the designations of: FR-1 (P-49) and FR-2 (P-50) respectively. So with a little knowledge of the product being evaluated for use, or in determining what solution(s) best work for your customer, a little knowledge of the code and applicable standards go a long way!

Arriving at a compliant solution.

After a few short questions with my beloved customer looking for “PT & FRTW”, it was determined that they simply wanted FRTW lumber & plywood. It is important to note that there are products available that are both preservative & fire retardant treated [the BENEFIT] which by code is done by pressure impregnation [the PROCESS].

We’ll dive into combination fire retardant & preservative systems in another post coming soon.

You want an ALTERNATIVE?

By | Uncategorized

 Alternative Materials & Methods and the Emergence of Spray-Applied Fire Retardants.

With the emergence of spray-applied fire retardants and other topically applied systems, I feel that it’s only pertinent to discuss how these products, which represent a viable alternative to traditional Fire Retardant Treated Wood, can be approved for use in specified and/or code required applications.

Alternative Materials, Design and Methods of Construction and Equipment is outlined in Section 104.11 of the IBC, and provides an alternative method for meeting building code requirements via an alternative material, in accordance with the alternative means and methods provision of the code, provided the product meets the same performance requirements as whatever you’re replacing. It’s also crucial that the alternative material/product is not lesser in quality, strength, effectiveness, fire resistance, durability and safety.

The Scenario.

For my example, I have a customer that wants to use fire treated plywood featuring a fire-retardant coating system instead of the traditional “pressure impregnated” FRTW or FRT plywood. In other words, this alternative product would not be FRTW (not pressure impregnated) but could serve as a code compliant alternative to FRTW if we can provide the required supporting documentation.

If you’re confused, don’t be. This process is simple once you understand: (a) what the code is asking for and (b) how to provide the answers/documentation to your local AHJ so they can make their determination.

At the end of the day, while this provision in the code exists, it’s up to the Code Official (AHJ) to approve or deny the alternative material/method for use based on the supporting data provided (e.g. Research Reports, Testing Data). If you want your materials to get approved for use, then you’d better do your homework and have your ducks in a row.

What the code says.

Let’s get into action and first understand what our requirements are by referencing Section 2303.2 of the IBC: Fire Retardant Treated Wood.

Fire-retardant-treated wood is any wood product, that when impregnated with chemicals by pressure process or other means during manufacture, shall have, when tested IAW ASTM E84 or UL 723, a listed flame spread index of 25 or less and show no evidence of significant combustion when the test is continued for an additional 20-minute period. Additionally, the flame front shall not progress more than 10-1/2” feet beyond the centerline of the burners at any time during the test.

The IBC defines FRTW as material that has been treated by a pressure process. The materials we want to use as an alternative to FRTW weren’t treated by a pressure process, therefore, we cannot label them “FRTW”. Fine, let’s call that product POTATOES. By the way, we have great POTATOES!!!

In order to meet the performance requirements of the 2303.2, our POTATOES must:

  • pass the 10-minute ASTM E84 Test, plus the additional 20-minute period, as defined.
  • In addition to demonstrating equivalence in performance, our alternative materials must also be evaluated for:
    • strength degradation
    • corrosion (fasteners)
    • hygroscopicity

*Since the FIRE testing component of this is the key to success here, we’ll focus on fire.

Teting Mumbo-Jumbo.

ASTM E84 is the Standard Test Method for Surface Burning Characteristics of Building Materials. This test lasts for a period of 10-minutes and provides two data points: Flame-Spread & Smoke Developed. The IBC requires an additional, or extended, 20-minutes of testing after the initial 10-minutes, making this test a “Modified E84 Test in accordance with IBC 2303.2”.

The Flame-spread Index, or FSI, details the tested material’s propensity to burn rapidly and how quickly flame spreads on the surface of the material. The Smoke-Developed Index is a measure of the concentration of smoke a material emits as it burns.

The most widely-accepted flame-spread classification system appears in NFPA Life Safety Code 101 – grouping flame-spread & smoke development by Class A, B or C, and this is where the IBC derives the baseline performance requirements for FRTW, and/or their alternatives from.

Class-A is what the IBC requires for FRTW materials (or their alternatives) and that is “Flame-Spread of 0-25, Smoked Developed 0-450”.

Summing it up.

Now that your product has been all tested and certified, the “presentation” portion of your facts for approval should be rather straight forward. First, provide your research report along with your “modified” ASTM E84 test results that demonstrate equivalence in performance to what was prescribed by the code, and make sure you have your strength, corrosion and hygroscopicity data are on point. This information is more often than not found within the research report IF that data point was in fact captured in the scope of the evaluation.

Gaining approval for an alternative product isn’t always a walk in the park. Some jurisdictions simply won’t allow certain products or methods for use, while other jurisdictions are much more open to outside-the-box thinkers and our creative solutions. As mentioned before, gaining acceptance begins with your product’s valid and supporting research reports from approved sources backed-up by test results from an approved agency. Last but certainly not least: know your product, know your audience, and prepare for your competition to try to shut you down. I say — bring it on!
