JNL wins J-frame case

Posted on Thursday 15th November 2018

Allegations that JNL’s J-Frame products had failed timber treatment Standards have not been upheld

After investigation into the claims under the Fair Trading Act, the Commerce Commission ruled

“there is insufficient evidence to substantiate the allegations made, or to show that there has been a

breach of the Act”.


J-Frame is a structural laminated veneer lumber (LVL) product manufactured by JNL and

independently certified to AS/NZS4357 (Structural LVL).


“We’re disappointed that J-Frame, an innovative product, with an unblemished track record, had

these claims made against it,” says JNL sales and marketing manager Gordon Wilmshurst.


“We have not had a single report of in-service failure of J-Frame in over 10 years in New Zealand.”


The Scion research trial confirmed that J-Frame showed no signs of decay after 12 months of

exposure to brown rot fungi in hot and humid conditions; and that the product resists decay as

effectively as boron-treated H1.2 solid wood”.


Mr Wilmshurst says importantly, the Scion research results were consistent with J-Frame’s

Codemark certification that specified building work be designed in accordance with NZS 3604:2011

or specifically engineered in accordance with NZS 3603:1993 and where hazard class H1.2 or less
