Lonza Wood Protection has installed an incising test rig to show customers the results of incising home-grown timber species.
The rig at Lonza’s (formerly Arch Timber Protection) Castleford headquarters will also be used to complete an in-depth study to further develop the company’s knowledge and understanding of incising technology.
Incising in-ground contact posts before treatment is being highlighted by the Wood Protection Association (WPA) as one method of achieving a better penetration of timber preservatives during the treatment process, especially with spruce.
Lonza developed the test rig and new incising patterns in partnership with a leading US equipment supplier. It says preliminary testing in the US has indicated “excellent” results in terms of treatment quality and regular and consistent incisions, while also maintaining an acceptable surface appearance of the timber.??
The required use of incising for home-grown timber species for certain end uses, predominantly in the highways sector, is being considered by the WPA.
“We have been researching the use of incising technology for a considerable amount of time, as well as investigating other controlled pre-treatment timber conditioning methods, in order to allow our customers to reap the full benefits of Tanalith E wood preservative,” said Ed Webster, Lonza Wood Protection’s engineering and technical services manager.
He encouraged customers to come and see how incising could perform with their treated timbers.
