![]() The first reason is that they can last for very long periods of time. If the window is maintained well, it can last for a remarkably long time as can be seen across London, which has wooden windows that are over 150 years old and still in every day use. This means that once the window has been made and fitted there should be no need for replacement if reasonable maintenance is upheld; hence no need to cut down more trees. Another reason why wooden windows are Eco-friendly would be with regards to the energy used in making a wooden window. There is little energy that goes into making a wooden window as compared to other materials such as aluminium. Apart from the energy used in making the window, the energy used in repairing it is far much less for a wooden window that it is for one made of aluminium. Energy conservation is one of the most important elements of environmental friendliness. Persons or companies who manufacture wooden windows should, if they have ethics, get their timber from well-managed forests. Some of these forests are entirely man-made and owe their entire existence to the timber industry as a whole. The fact there is demand for wooden windows and timber as a building material means that those in the trade have to ensure that they conserve the trees and forests where the timber comes from. If we did not do this, we would have run out of timber many years ago. Of course, no single business person would like to run out of business. The timber dealers are therefore forced to plant more trees as they cut down others. This is for the sake of their businesses, even if not out of love from the environment. The disposal of waste from wood used to make such a window is also very Eco-friendly. The waste can be used by the manufacturer for heating purposes within the wood manufacturing plant. The heat this produces can for example be used to run machines and so on. There is therefore very little wastage when it comes to using wood. This compared to the waste material from a window made of PVC. Such waste is usually disposed off by being burnt especially in less developed countries as recycling costs are quite high. The burning of PVC waste is very harmful. It leads to the production of poisonous gases, which are released into the environment, thus causing air pollution. These waste products are a major environmental hazard. Many of the paints used in the wooden window industry are now water based and biodegradable. This means that they are also Eco-friendly. The same case applies to the stains used on other timber products like fencing and furniture. This may not be true for paints and stains used in a window made of other materials. Biodegradable paints and stains are of no harm to the environment. This is also another reason why a wooden window is more Eco-friendly. Last but not least, it is also no secret in the scientific community that as trees grow older; their ability to absorb carbon dioxide form the atmosphere is greatly reduced. It therefore actually helps to cut down such trees and replace them with younger ones, which can absorb carbon better and faster. Since these trees are cut down in order to make wooden windows, it would be correct to conclude that timber windows are good for the environment for this reason as well. |
