Here at Gembuild we use three different types of wood cladding or external cover; larch, cedar and thermowood.
What effect does each have on the final building? Where do they come from and how long do they last without needing to do any maintenance work?
We are surrounded by it, we have walked under it, we have known about it for as long as we can remember. We have sat on it, slept on it, burnt it and eaten from it. We have walked on it, put things in it and we have touched it. It is wood, it is lovely, it smells nice, it lasts, we love it.
No doubt we take wood for granted growing as it does whenever there is a clear patch of earth but what does the wood in your garden office have to say? What is the hidden story behind the bark?
Gembuild’s designs use larch, cedar and thermowood for the external cladding, which can be dyed in different colours.
Wood knots, grain and textures are generic, and vary with their climate and habitat but each unique giving the offices a natural and individual appeal.
Take the Siberian larch which having grown in arboreal forests with wintering temperatures of -50 ‘C has endured conditions that can be variable and uncertain. Yet, during summer, close to the Arctic circle, there is midnight sun on the tree tops but underneath, wild boar, red deer, bears and tigers endure harsh conditions.
This wood, once felled and treated, survives the Western European climate for up to fifty years or longer.
Or take the Canadian western red cedar, still sent down the Fraser river to the Strait of Georgia and the Vancouver harbour, floating under Lions Gate bridge, where lumberjacks for centuries felled the statuesque tree for its beauty and utility.
It has qualities that make it a practical option for the outer walls of your garden office, as well as a certain quality that means for the owner, less upkeep.
Our third type of cladding is thermowood. Although wood is good to go thermowood is especially chic at the moment.
It was no surprise that without courting controversy people wanted to further improve wood’s insulation properties using modern techniques while keeping it’s natural qualities. No need to debate the natural credentials if you only treat it with water and steam.
So the increasingly popular thermowood, became part of a growing area of timber framed houses in the UK. The scale of their use shows it is now an acceptable building material
Thermowood is Scandinavian, infact it is manufactured in Finland. You can identify it because having been treated under tightly controlled conditions as it has a registered trademark, from The International ThermoWood Association.
If you have this conditioned thermowood you can expect a better and more durable insulator, with a thermal conductivity reduced by at least 20% so stopping heat escaping that much better.
This much you can know you don’t take too many risks when you choose wood cladding and each plank has a story to tell with a whole world behind it.
