The following facts are from the UN-ECE (The United Nations Economic Commission for Europe).

The production of a tonne of any raw material before it is utilised in manufacture involves energy consumption. This energy is known as ‘embodied energy’.
uPVC consumes 45,000 KW/Hrs/tonne, Aluminium 25,000 KW/Hrs/tonne, and Wood 2000 KW/Hrs/tonne.

There are now more trees in northern Europe than there were 100 years ago, and the annual surplus of timber in Europe is 252million/m3, which is 30 times total UK consumption.

This substantiates the fact that wood is a renewable raw material which costs far less to produce than other alternatives. This should preclude any concerns regarding the destruction of the world’s forests. The annual surplus is all due to the reforestation programs that started thirty years ago.

Vrogum is only using wood from sustainable forestry, i.e. wood being replanted, and thus it stays a constant natural resource without putting a strain on the environment and future generations.
