Why Use Cedar?
The best material to use for your greenhouse is a heavily debated topic – here’s our take on it
We’re in the business of making traditional greenhouses and traditionally they are made from timber. You get a warmth and solid feel from timber that you don’t get from metals and plastics and it insulates better. Some timbers, however, are susceptible to decay over extended periods outdoors and can twist and move when exposed to moisture and different temperatures. Cedar is different. It contains natural extractives that are toxic to many fungi and bacteria that usually attack other timbers. Unpainted cedar will last for years outdoors but eventually rain and sunlight remove oils from its surface and it becomes tired and damaged turning grey and pitted. Painting it locks in the extractives and further protects the outer surface.
As a building material it’s carbon negative:
Cedar is dimensionally very stable which means its size and shape alters very little as it absorbs and releases water vapour from the air around it. This makes it ideal for use in greenhouses where the environment can change regularly.
As a building material it’s carbon negative: the carbon absorbed from the atmosphere as a tree grows is locked away when it’s cut down. When a new tree is planted, more carbon is locked away. It also uses far less energy to convert a tree into a useful material. By comparison, it takes about 20 times more energy to produce a kilogram of aluminium than it does to produce a kilogram of timber.
By using cedar we get a truly traditional greenhouse that will last for many years without the typical problems associated with other timbers and all whilst having a positive effect on the environment.
