Weyerhaeuser TJI Joists with Flak Jacket have been found to be defective and they produce an unpleasant odor. There is also concern the materials used to manufacture the joists contain dangerous chemicals that can cause health complications.
Are TJI Joists Dangerous to Have in Your Home?
There is evidence that homes featuring TJI Joists in their construction are not safe for habitation. Homeowners living in homes containing these building materials have been asked to temporarily relocate while Weyerhaeuser remediates the problem. Many of the homes featuring these joists are new construction and not yet inhabited.
Following reports of an unpleasant odor in newly constructed homes, Weyerhaeuser found the Flak Jacket coating applied to its I-joists were off-gassing.
The coating on the joists contains a formaldehyde-based resin that is used to enhance the fire resistance of the product. It is only a problem in products manufactured after December 1, 2016, which were only used in certain markets. There are approximately 2200 homes in various stages of construction affected by the problem.
Homes are undergoing one of three mediation solutions, including:
Top Coat Solution (Secret Paint)
The application of the Top Coat Solution does not create a barrier to block formaldehyde, but instead creates a “scavenger” system that uses a chemical to capture and hopefully remove the formaldehyde. The company has not released information about the chemical in the paint, so it’s impossible to tell if the solution is effective.
Coating Removal Solution
This method of remediation utilizes dry ice, sanding scraping, and micro-planning, followed by an application of the secret Weyerhaeuser’s Top Coat Solution.
This method of remediation removes the TJI Joists from the home.
It is considered the most effective of the three remediation methods because it removes the formaldehyde-containing product from the home. However, this is the most expensive and time-consuming of the three options.
Home Builders and TJI Joists
New home builders have taken a more aggressive approach to dealing with the TJI Joists problem. Many of them are removing and replacing all joists homes that have been completed or are partially completed. Others are using a cryo-blasting method to remove the coating and then applying the Top Coat Solution.
Some builders that have received requests from consumers to buy back their homes featuring TJI Joists have agreed to do so. There are also instances of companies cancelling pending sales of these homes.
Weyerhaeuser TJI Joists Reduce Home Values
Homeowners are not only concerned about the safety of their homes, but also about what the TJI Joists will do to the value of their homes.
Even if your home undergoes remediation, it could have a lower market value than homes that never featured the joists. It’s possible that some markets could legally require homeowners to disclose that formaldehyde-containing products are or were present in the home, and give a detailed description of how the products were removed.
There are also concerns expressed by homeowners who did move into the affected homes that the off-gassing might have affected their belongings. There is an investigation underway to determine if the formaldehyde contained in the joists could have seeped into other items and made those items dangerous.
Weyerhaeuser is facing legal action filed by homeowners affected by the defective products. These homeowners have a wide variety of allegations against the company, including breach of contract, consumer fraud, and negligence.
They are concerned the use of the TJI Joists in their home could cause them to develop serious illnesses and they must undergo continued medical monitoring. Many of them have suffered emotional distress because of the actions of the company.
