NADRA Atlanta Chapter Meeting

June 13, 2011 | Hello Everyone,
I hope everyone is doing well and that the spring season has breathed new life into your activity levels.
I’d like to remind you of our upcoming Atlanta NADRA Chapter meeting next Tuesday, June 21st at 5:30 at the Prado Taco Mac. It will be inside complete with AC and sound system.
David Elenbaum and Guardian will be sponsoring this event. Guardian has incorporated a policy that along with a couple of manufacturers is leading the decking industry in a direction that is long overdue. You will find what he has to say interesting and encouraging.
Lindsay Ranly and Stephanie Kane will be our guest speakers addressing “multi media”. This is a topic that all in attendance will find interesting and is “the” marketing avenue of today’s contractor. The more we learn and understand the better our businesses will prosper.
Hopefully our committees have had a chance to make some progress and I’ll ask that one person from the Recruitment and Deck Safety groups take a moment to update us on their activities and progress.

Please make an effort to attend and bring a guest.

Bobby Parks
Atlanta NADRA Chapter President

Ask NADRA: Deck Ventilation Requirements

April 30, 2011 | Ken from Orangeburg, SC asks:

“I am wondering is there a minimum height requirement for a
deck to allow for adequate ventilation under the deck. Is this
measured to the top or bottom of the decking timber?”

Glenn Mathewson, NADRA’s Technical Advisor, responds:

Hello Mr. Panitt.

Thank you for turning to NADRA with your questions about the Decking and Railing Industry. We are certainly happy to provide you guidance. The International Residential Code (IRC) and International Building Code (IBC) do not specifically regulate the ventilation of areas underneath exterior decks. IRC Section R408.1 describes the ventilation requirements for under floor spaces, including the minimum net free area, but it is in reference to areas under buildings that are enclosed by foundation walls. While it would certainly be good practice to maintain moisture control under decks that are very low to the ground, its not part of the minimum standard set forth by the IRC. However, in the case of manufactured decking or other products, the installation requirements of the manufacturer are essentially part of the code. This may be from a direct reference to, such as section R317.4.1 in the 09 IRC for wood/plastic composites or through approval as an “alternative”.
I know at least two prominent tongue-and-groove composite decking products that require a minimum height above grade to make up for the lack of air flow between the boards. In both cases the distance was 12 inches of vertical space beneath the bottom of the framing, though the percentage of perimeter where it was required varied. You must always adhere to manufacturer’s installation instructions, not only for good practice, but also for code compliance.
For spaced deck boards, the gaps would likely suffice for ventilation. They may be narrow, but they’re evenly dispersed. One thing to consider, however, is the size of the gaps and the material used. If swelling of wood, expansion of thermoplastics, proximity to heavy autumn leaf fall, long snow coverage or poor maintenance/cleaning is likely, the gaps may close. In that case, additional ventilation openings or greater clearance to grade would be a good plan.

I hope this information is of assistance to you and the visitors of the NADRA blog.

Ask NADRA: Is Fungus Destroying CCA Wood?

April 30, 2011 | Wallace from Midway, GA asks:

“[What do I] need to know about fungus destroying CCA lumber?”\

Huck DeVenzio of Arch Wood Protection Reponds:

From your question and e-mail address, I’d guess that you have heard reports from a guy (Sam Brooks) saying that there is a strange fungus destroying CCA-treated wood in coastal areas. He says his company has a solution.

I’m amazed that this non-story is getting as much attention as it has. From all we have been able to piece together, there is no strange and destructive fungus. The photos he shows involve an occasional condition called tracheid separation or salt-killed wood. It does not involve a fungus and it is not a failure of CCA preservative. It is caused by wicking of salt into some pieces of wood. A document (link provided below) published by experts at Mississippi State University is attached; it explains the phenomenon. This was written in March, largely to counteract the assertions appearing in the Charleston-Savannah area. I have another technical paper if you need more information.

This “salt kill” can cause problems for marine piling, but it tends to be scattered and it is not caused by fungi. I do not know anything about the solution offered by Mr. Brooks, but you have to be suspicious when he doesn’t even understand the cause of the problem.

Ask NADRA: Preserved Wood For Wet Climate

April 26, 2011 | A concerned homeowner in British Columbia asks:

I have a 3-foot crawlspace which has a damp concrete floor whenever we get heavy rain. Consequently, the exterior pony walls carrying the fiberglass insulation are beginning to decay. Can I replace the pony walls with preserved wood and not put a finish cladding on it? Is there a toxicity factor here if the wall is not properly sealed? Timing and budget are not big factors here as much as having the job done right. Thank you.

Huck DeVenzio of Arch Wood Protection Reponds:

If you purchase properly treated wood (we, of course, recommend the Wolmanized brand) intended for ground contact, you can be confident that the wood will resist fungal decay for many decades, and you don’t have to be concerned with sealing or cladding. Treated wood has been used for years in Permanent Wood Foundations (made of treated studs and treated plywood), framing for all homes in Hawaii (where termites necessitate this), and for the sill plate of nearly all homes in North America. In all of those applications, many left unfinished, there is not a single known adverse health or environmental incident from the preservative in the wood.

Because of the dampness and your past problem, I would try to get wood treated for ground contact, even if most of the lumber will be above ground. That gives you an extra measure of security.

You can probably find properly treated wood at a lumber dealer near you. I hope this helps.

NADRA Teams Up With LBM Journal

North American Deck & Rail Association Names LBM Journal as its Endorsed Publication for the Distribution Channel.

April 4, 2011 | The North American Deck & Rail Association (NADRA), the established leading resource of information and ideas for deck builders and other industry professionals involved in the outdoor living industry, has named LBM Journal as its endorsed publication for the industry’s distribution channel.

The organization has existing solid support and involvement from deck builders and decking manufacturers. To connect the two groups, NADRA’s Board of Directors voted on March 23rd to name LBM Journal as the association’s endorsed magazine for the distribution channel.

“Outdoor living has emerged as a true ‘break-out’ category for our subscribers—lumber/building material dealers,” said Rick Schumacher, LBM Journal editor and publisher. “LBM Journal identified this trend at our publication’s launch in 2003, and has established itself as the leading resource for members of the distribution channel. Working with NADRA is the natural next step in helping our readers—along with their suppliers and their customers—to grow their sales and their business. We appreciate the vote of confidence from NADRA’s board, and very much look forward to helping NADRA accomplish its mission and strengthen its position among our readers.”

“NADRA is committed to supporting and strengthening the entire deck and railing industry in North America—everyone from manufacturers and wholesale distributors to deck builders and homeowners. Lumberyards, the companies who subscribe to LBM Journal, are a critical link in this chain,” explains Michael Beaudry, executive vice president of NADRA. “By working with LBM Journal, we hope to boost the involvement of dealers and distributors—which will be good for the entire industry.”

SSG Marshall Diaz has been honorably serving his country for 13 years and is currently in Active Duty. During his last deployment to Afghanistan, he was wounded and medically evacuated back to the U.S. From May of 2008 until April of 2010, SSG Diaz was in the Warrior Transition Battalion located at Joint Base Lewis-McChord. SSG Marshall is honored by a Bronze Star and a Purple Heart, as well as many other prestigious awards during his career. SSG Diaz also takes time to serve his local community by volunteering with the local Boy Scout Troops and still sets time to volunteer at a local Veteran’s home.

On his application SSG Diaz noted “When I was given the option to get out of the Army, I chose the only option for me, and that is to continue to serve my country. Although my rehabilitation is an ongoing process, I hold my head up with pride for there is no other country in this world that I would rather live in, than the United States of America.”

Western Washington NADRA members are humbled and honored to break ground for the west coast and know the deck could not have gone to a more deserving family.
