Environmental Policy

At James Donaldson Timber, we are committed to assessing the environmental impact of our methods of manufacture and materials used for all of our business activities. We look to use certified timber in all of our products and reduce the environmental impact of construction wherever possible.

We aim to show that our goods are produced in an environmentally responsible manner. To do this and respond to our customers' needs and expectations, we keep sight of the wide range of raw materials; production processes and countries of operation in producing our goods.

quality control

JDT has achieved registration to continued chain of custody. This system ensures that timber is guaranteed to meet environmental guidelines from the forest floor to the shop floor.

We recognise that timber, as a building material, is a truly renewable resource when properly managed, so fully endorse the requirements of our PEFC and FSC chain of custody scheme, to ensure that where possible our timber is legally and sustainably sourced.

JDT was the first Donaldson site to achieve certification to FSC in May 2002. They later added PEFC certification in May 2004.


James Donaldson Timber Limited is continually striving to improve our processes and products to give you the best, in the safest and most sustainable way.

To ensure the quality of our products we are certified to ISO 9001 standards and operate an on-going, in-house quality programme; throughout the life cycle of the manufacture of our products they are regularly checked for quality control.

CE Information

For many years, wood and wood products used in the construction industry in the UK have been covered by a range of British Standards and more recently, European Standards. These provide designers, specifiers, buyers and users with assurance of fitness for purpose and performance.

In an effort to reduce the technical differences between the different European countries, the Construction Products Directive (CPD) and CE marking were introduced.

What is CE Marking?
CE marking is a mandatory conformity marking for products sold in Europe. The CE marking is the manufacturer's declaration that the product meets the requirements of the applicable EC directives.

When does CE Marking come into effect?
From July 2013 all construction products, including roof trusses and Posi Joist products are required to have a CE Mark.

Can DTE offer CE Marked products?
Yes we can. Please Click Here for our CE Certificate, our Declaration of Conformity, and our technical information sheets for each manufacturing site for trusses and posi joists. Our other products i.e. I Joists, Chipboard Flooring will have the primary manufacturers CE Mark detailed on the product.
