The Material for the Future

Wood is an extremely valuable resource. This unique material plays an important role in the life of people. It is so important that life of mankind is hardly possible without it. People began to use it many, many years ago as fuel, shelter, weapons for protection from wild animals and to get food.

Wood is widely available and is relatively easy to handle and convert into products. Wood provides us with a large variety of products and demand for wood continues to increase.

Timber is a more "environmentally friendly" building material than all the other materials presently available. There are a number of reasons for this:

· It is a natural building material which our forests give to us. 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 results in the release of oxygen and purification of the atmosphere.

· Timber is a renewable resource. It exists in nature in unlimited quantities. It is capable to meet our needs now and in the future.

· Timber is reusable. It 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.

· Timber is biodegradable. It does not damage the environment. When it returns to the environment it enriches it with nutrients.

· It is energy-efficient. When we convert wood from raw material to a usable product we see that timber is very energy-efficient. It is the most efficient in its conversion process among any other comparable building material. One study revealed that the production of a ton of timber requires only 435 KW hours of electrical energy whereas that of steel needs 3780 KW hours and that of aluminum requires 20,169 KW hours.

· Timber is the best natural insulator for our buildings. It helps to keep them warmer in winter and cooler in summer. 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.

The community in general is 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. It is indeed the material for the future.
