Introduction to timber - Wood Campus.jpg

Wood is commonly recognised as sustainable by virtue of it being a renewable resource. In addition to the provision of timber, forests represent some of the richest biological areas on Earth, providing food and livelihoods for millions of people and habitats for wildlife.

 

Through the work of organisations such as the Programme for the Endorsement of Forest Certification PEFC and The Forest Stewardship Council FSC, modern forestry standards ensure wood is harvested and procured in a responsible, sustainable way, with new trees being planted to replenish stock. 

As they grow, trees absorb CO2. By building with timber, carbon from the atmosphere is being stored in the built environment. So it follows that using wood stimulates the expansion of managed forests and reduces the levels of global warming gas. Why wouldn’t we encourage the use of wood?

The environmental impact of building decisions, including material selection, is of increasing interest to both specifiers and builders alike. Compared with alternative building materials of similar durability, such as concrete or steel, the cost and energy input of pre-treated wood production is relatively low.

 

But what about the 'chemical' aspect of treatment? Our lives are full of materials which have ‘chemical additives’ if we were to eliminate their use altogether, our lives would be very different – and not necessarily for the better. The industry continues to introduce products which are better targeted towards the organisms we wish to control and are less hazardous to the wider environment. This trend will continue. By assessing the benefits gained against the negative impacts then the justification for timber treatments can be appreciated.

Wood Campus have many on-line resources covering amongst other topics, timber sourcing, procurement and the benefits of building with wood.

The Passive House Movement

Becoming increasingly popular, the principles of this movement are concerned with efficient design and construction techniques. Passive buildings manage their interior climate with less or no energy, resulting in reduced carbon footprints, using as much as 90 percent less energy than typical buildings. Wood can help realise such passive design principles because of its natural thermal insulating properties, water resistance and structural integrity. See passivhaustrust.org.uk

We spend a lot of time indoors so the impact our buildings have on how we feel, work, learn and relax is an increasingly researched subject. Wood has a natural warmth whilst reminding us of the great outdoors. Wood is a healthy building material and preservative treated timber has been proven to have insignificant effects on indoor air quality.

Biophillic Design 

The premise behind biophilic design is the idea that incorporating natural elements in the built environment, such as wood, water, sunlight or plants, can actually improve overall health.

In healthcare, care home and office environments, designers are embracing biophilic design, rediscovering the aesthetics of wood to improve patient experiences and staff performance. BRE group are carrying out extensive research - read more here www.bregroup.com

WPA Waste Guidance Note 2019-1.jpg

Preservative pre-treatment extends the service life of wood for many years. At the end of its service life treated wood can be re-used or recycled for approved applications or disposed of in a way that minimises any potential for environmental damage.

 

Trackwork who are WPA Members, run a dedicated treated wood disposal service. Energy from their Waste plant is audited, monitored and licenced by the Environment Agency and burns hazardous waste wood to generate electricity. This goes on to power their Doncaster site and exports surplus energy to the National Grid.

 

The WPA publishes a Guidance Note about the re-use, recycling and recovery of treated wood related waste streams and, where this is not possible, its disposal.

Most modified woods can be handled as any other untreated wood waste. They do not contain any toxins or heavy metals that can harm the environment and can be disposed of at the end of their service life by either burning or placing into the normal waste system or be re-used or recycled for approved applications. See the wood modification section which has direct links to product manufacturers for more information.

 
 

Wood has long been used as a structural and finishing material in construction, just look at the iconic buildings still around today. The appeal for wood across building segments comes from its unique aesthetic qualities, natural durability, flexibility, installation efficiency and ease of use. Coupled with timber protection technologies and advanced engineering practices, wood can add to environmental cost savings, building performance and speed to market.
