The great advantage of Siberian larch and Canadian cedar cladding is their high resistance to decay and high durability from natural preservatives. We use both types of cladding for our garden buildings and all our cladding is FSC or PEFC certified timber from well-managed forests.
Siberian larch has long been used for cladding in Russia and Europe and is very slow grown and consequently much denser, straighter grained and less knotty.
Western red cedar has become one of the most popular species of timber cladding, both internally and externally. The majority of red cedar is imported from North America, particularly Canada. It is also straight grained and largely free of knots.
Our cladding has a fifty year plus life without any need for treatment. The natural oils and resins within the boards keep them free from fungal and insect attack.
As well as a long maintenance free life, you’ll also get pleasure from seeing your garden office changing colour to a beautiful silvery grey.
We have had a cedar panel on test at our offices for over 7 years now (see below). This has gone through several stages of greying but has now settled into the lovely silver colour you see on old churches.
You must not confuse the natural and healthy weathering of your building with fungal attack. The progress of greying is influenced by rainfall and the orientation of the building, and eventually the whole unit will settle in to a uniform silver colour and will remain that way for the many years of life you can expect from a Gembuild garden building.
It may well go through 50 shades of grey before it reaches its final colour but I hope you will agree it was well worth waiting for!
