Timber – Environmentally A Wise Choice
Wood is an extremely valuable resource. This unique material has played an important role throughout history. It is impossible to imagine that early mankind could have survived without wood for fuel, shelter, and for weapons for protection and hunting food.
People have always been dependent on wood because it is so widely available, is relatively easy to handle and convert into products, and can be used in many different ways. Today, wood is just as important to society. Wood provides us with a large variety of products and the demand for wood continues to increase. To maintain and improve the value of wood to the community it is essential that the practices involved in managing forests, converting wood to products and using wood products are continually reviewed and researched.
Timber is considered as being a more ‘environmentally friendly' building material than all the other materials presently available.
There are a number of reasons for this:
-
Naturally-Occurring
Timber is a natural building material produced in our forests. Trees absorb solar energy from the sun and with the use of water, carbon dioxide and chlorophyll as a catalyst, convert it to cellulose (wood). This conversion process, known as photosynthesis, results in the release of oxygen and purification of the atmosphere.
-
Renewable
Timber is a renewable resource. It does not exist in limited quantities; rather it is constantly forming and growing. If managed sustainably, it is capable of continuing to meet our needs, now and in the future.
-
Reusable
Timber is reusable. Timber is easy to work with and does not involve the use of a lot of energy in comparison to other materials. This means that over its ‘lifetime' a piece of timber can have many uses.
-
Biodegradable
Timber is biodegradable. After it has served its use/s, timber can be disposed of without damaging the environment. In fact, when it returns to the environment, it often enriches it with nutrients formed from the breakdown of cellulose.
-
Energy-Efficient
When converting wood from raw material to a useable product, timber is very energy-efficient. In fact, it is more efficient in its conversion process than any other comparable building material. One study revealed that the production of a tonne of timber requires only 435 KW hours of electrical energy, whereas a tonne of steel needs 3780 KW hours and a tonne of aluminium requires 20,169 KW hours!
-
Natural Insulator
Timber is the best natural insulator for our buildings, helping to keep them warm in winter and cool in summer. It is used as a standard building material all over the world, in both arctic and tropical countries. Its superb insulating properties mean that less non-renewable fuel is needed for heating and cooling.
-
Timber Reduces the Greenhouse Effect
Forests help to reduce the level of greenhouse gases in our atmosphere, because they use and store carbon to make woody tissue and leaves. This helps to purify our air.
Additionally, when different sources of building materials are being manufactured, large amounts of energy are required and fossil fuels burnt, resulting in carbon dioxide being released into the atmosphere. By managing forests for timber production and using that timber for building materials, we can help to protect our climate.
The community in general is becoming increasingly conscious of our natural environment and the need to use it wisely for the benefit of all. Timber provides society with a variety of uses and environmental advantages. Timber is indeed the material for the future!
