How to book your virtual CPD seminar

UPDATE: In light of the Coronavirus pandemic our RIBA CPD is now available virtually via video conference.

Hanson Plywood is proud to form part of the Approved RIBA CPD Providers Network offering a unique and informative virtual CPD to support remote access across the practice team entitled:

‘Plywood: A Definitive Guide To Specification’

This virtual CPD forms part of the RIBA Core Curriculum programme and offers architects, specifiers and designers the opportunity to gain more in-depth knowledge relating to the manufacture and selection of plywood as a construction product in line with European Standards leading to more informed specification.

The seminar focuses on:

  • The key features and origination of plywood within a global context.
  • The legal and environmental framework that impacts on plywood specification.
  • The key aspects and variability of the plywood manufacturing process.
  • The origination of Marine Plywood and the disconnect with current European Plywood Standards.
  • The European Technical Standards that underpin robust plywood specification.
  • The key features of the different birch plywood face grades available.
  • Reaction to Fire European Standards applicable to plywood.

FAQ’s

  • This lunchtime seminar will last 50 minutes which includes time for Q&A’s.
  • Double CPD points are awarded to attendees.
  • Certificates of Attendance are issued upon completion of the seminar.

NBS Source

Backed by the RIBA, NBS Source is the new digital platform that integrates RIBA Product Selector.

We offer a range of high-quality plywood products listed within NBS Source that provides specifiers with all the tools and digital information needed to find, select and specify the correct product to meet project requirements.

     

Plywood – Specifications

This standard was originally in three parts, but was reissued in 2003 in a single part as follows:

The 2003 edition of EN 636 retains the designations -1, -2 and -3 from the previous three part standard to represent dry, humid or exterior conditions of use.

The environmental conditions for which each of these types of plywood are considered suitable are defined according to the parameters laid down for use classes in BS EN 335 durability of wood and wood-based products. Use classes: definitions applicable to solid wood and wood-based products.

Dry Conditions:
For interior applications with no risk of wetting, defined in Use Class 1, with a moisture content corresponding to environmental conditions of 20°C and 65% relative humidity.

Humid Conditions:
For use in protected exterior applications as defined in Use Class 2, with a moisture content corresponding to environmental conditions of 20°C and 85% relative humidity.

Exterior Conditions:
For use in unprotected external applications, as defined in Use Class 3, where the moisture content will frequently be above 20%.

EN 636 also introduces bending strength and modulus classes based on bending tests to EN 310. These give a designated strength (F) and modulus (E) parallel and perpendicular to the face grain. An example designation would therefore be F10/20, E30/40.

EN 636 gives minimum values for each of the classes and EN 12369-2 gives corresponding characteristic values for use with each of these classes.

Plywood for use in construction must demonstrate compliance with the Construction Products Directive (CPD). The most straightforward route to achieving this is by demonstrating compliance with EN 13986, and therefore must carry a CE mark.

Decision Making Guidance

Please see a list of considerations to take into account when specifying a product from our Plywood range:

 

  • Consider the performance required of the component and duration of service life.

 

  • Determine the Use Class of the situation in which the wood-component will be used and the biological agencies that threaten it.

 

  • Assess whether the durability of the plywood to be used is sufficient. If not, select for the component a more durable type of panel or choose another solution such as design or preservative protection.

 

  • The specification and application of plywood for Use Class 3 should take into account the importance of sealing the edges of panels in order to achieve optimum levels of performance. 

 

  • Where a project has specific requirements in terms of face grade, grain and colour please contact us directly to discuss details.
