At Jewson we ensure our plywood range is sourced from plantation grown hardwood and softwood timber. All of our hardwood plywood is grown from temperate hardwood species mainly Eucalyptus, Poplar, Beech and Birch. Our range of panel products come with either FSC ® or PEFC ™ chain of custody and are E1 or CARB2 compliant with respect to formaldehyde emissions.

We take the business of supplying certified, fit for purpose products very seriously. From transport and construction, packaging to furniture, whatever the end use we have the right product to meet the requirements the job demands.

Standards and grades guide

Plywood Durability EN636

EN636-2 – Plywood for use in humid conditions.

BS1088-1:2003 – “Marine” plywood should have outstanding resistance to bio-deterioration (durability) over time. Biological durability of marine plywood is expected to be greater than that of plywood of the same species that meets the requirements of BS EN 636-3.

GLUE BOND EN314-2

Plywood glue bond is divided into three classes dependent on moisture resistance.
Class 1 – For interior use (urea glue).
Class 2 – For humid conditions (melamine glue).
Class 3 – For exterior conditions (phenol glue).
