These days we all like to do our best for the environment, but what is the greenest option for your new garden shed? We take a look at three materials: timber, concrete and TPR.
The vast majority of garden sheds are made from timber, largely because it is cheap. Softwood is most commonly used, which is faster growing and better for the environment than hardwood and usually comes from responsibly managed forests.
However it degrades quickly and is treated with strong chemicals to lengthen its life. These harmful substances will leach into the soil over time, and when the wood rots, the shed will need to be replaced.
Replacing a shed makes a significant carbon footprint, which will include the wood being harvested and processed, the shed being manufactured, transportation at every stage and even disposal of the old shed.
A concrete shed may seem a better option, since it is unlikely to be replaced for many years. However, concrete is one of the world’s primary sources of carbon dioxide, a major contributor to global warming. In fact, the cement industry as a whole is responsible for 5% of the total global output of CO2.
TPR presents a more sustainable alternative. TPR uses waste plastic that cannot normally be recycled to make panels stronger than concrete, and is manufactured in the UK by a cold process supported by The Carbon Trust. Brodco’s DaylightSecure TPR sheds are guaranteed to last 50 years, and at the end of their lives are recyclable.
In addition, The Association of Chief Police Officers estimate that crime accounts for 2% of the UK’s total carbon output – and the DaylightSecure is the only shed they recommend to reduce crime.
