Assessing the Carbon-Related Impacts and Benefits of Timber in Construction

Assessing the Carbon-Related Impacts and Benefits of Timber in Construction
||, ,
This paper explains how to account for carbon in timber buildings and Environmental Product Declarations (EPDs) by rigorously applying the latest European Standards and the RICS Professional Statement on Whole Life Carbon Assessment in the built environment.

Assuring Quality
||
Where a flame retardant (FR) is added in the factory during the manufacturing process for MDF, OSB or plywood then that manufacturing process should be subject to factory production control (accredited by a notified body). The product should carry the CE mark and be accompanied by a valid Declaration of...

Combustibility

There are four recognised stages in the development of any fire: Ignition, Spread and Growth, Flash point into a fully developed fire and Eventual Decay. During the early stages, when a fire is still becoming established, the important factors are: Ignitability, Spread of Flame, Smoke Production and Flaming droplets.

Understanding Fire Protection Terms
||
It is vital that any flame retardant treatment incorporated into a building provides long-term, predictable performance backed by independent verification. Before specifying enhancement using a flame retardant, two specification fundamentals must be established: What reaction to fire performance is required? and What is the service environment?.

Fire Rated Wood-based Products
||
CE marking of construction products (those and only those covered by a harmonised European standard) is mandatory under the Construction Products Regulation (CPR). Harmonised standards include guidance on the minimum information that should be included with the CE mark.

External Timber Cladding
||
Building Regulations are intended to ensure that a reasonable standard of life safety is provided in the event of fire. The appropriate use of timber products can play a critical part in improving the performance of buildings in fire situations and in extending the time available to occupants to exit...

Understanding a Fire Test Classification
||
Wood and wood-based panels can perform well in fire if they have been enhanced using a factory controlled process to either impregnate them with flame retardant (FR) or apply an FR coating to the surface. Panel products can also be manufactured containing a flame retardant. In all cases, the products...

Understanding The Flame Retardant Treated Wood Supply Chain
||
Those who manufacture construction products for which a Harmonised European standard exists have an obligation to draw up a Declaration of Performance (DoP) and apply a CE mark when the product is first placed on the market. The key CPR definitions are explained in Guidance Note WPA FR 4.

Panel Guide Full Book
||
PanelGuide gives the panel user and specifier guidance and information on the use of wood-based panels in an authoritative and comprehensive manner. It covers all the main types of wood-based panel: • plywood (including blockboard and laminboard) • particleboard (chipboard, flaxboard, cement-bonded particleboard) • oriented strand board (OSB) • fibreboard...

The Builder’s Guide to Plywood
||
Plywood is a highly versatile building material which spans a wide range of applications from wall and floor sheathing to designer interiors and glider fuselages. There are many types of plywood available, including specialist tropical veneers such as marine plywood which, while having very good weather resistance and strength properties,...
