naturally.absorbs.moisture.from.the.surrounding.environment..This.can.cause.the.product.to.alter.
dimensionally..Sealing.the.product.with.a.good.quality.paint.or.stain.system.dramatically.reduces.the.
incidence.of.dimensional.change.and.increases.longevity.
Recommended.procedure:
1.. Fill.nail.holes.with.an.exterior.grade.woodfi.ller.
2.. Sand.back.until.surface.is.smooth.and.completely.free.from.dirt.and.dust.

PRODUCER STATEMENT
Tasman Consulting Engineers Ltd have been engaged by Prowood to prepare span tables and charts for the PROLAM® lintels,
beams and posts as presented in the PROLAM® Post and Beam Manual.
The design has been carried out using sound and widely accepted engineering principles to the requirements of AS/NZS1170:2002,
NZS3603:1993 and NZS3604:2011 using the timber properties for GL8, GL12 and GL16 glue laminated timber.

Fixing
Fixing of the decking panels is achieved by either nailing or
screwing. Coach screwing or bolting may be used on the
thicker decking where the heads would be recessed. Loose
tongues in decking 115mm and over are fitted on site and only
elastomeric glues should be used if the tongue is to be glued.

1.1
Span governed by deflection 1/400, or strength.
*These limits on spans have been set to reduce floor
liveliness. Floor dynamics is a complex consideration
and experience shows that floor spans based on
strength and static load deflection limits alone can be
unacceptably lively.
