INSULATION & SIDING
Recycled textile insulation is an environmentally friendly insulation material produced mainly from recycled textile. It consists of 90% recycled clothing and the clothing collection and sorting is done by people with a disadvantage in the labour market. It has approximately the same insulation value as our environmentally friendly sheep wool insulation.

Spruce is the wood most commonly used for exterior facades in all of Scandinavia. It is low in weight and has medium density. The strength properties are good. Its cellular structure makes it more resistant to moisture compared to pine for instance and it is very durable when painted or stained. It is also readily available making it a cost effective option.
ThermoWood outer siding
ThermoWood is Scandinavian pine wood that is heated in special ovens to 180 - 230°C for several days using only heat and steam - i.e. no toxics whatsoever. The addition of steam prevents cracking and the oxygen content in the air is kept low to prevent the wood from burning up. In the process, the chemical properties of the cell walls of the wood change, giving the wood a greater resistance and durability to both rain, sun and wind. In fact, the facade does not need to be painted for protection as necessary with untreated wood. The process of heating destroys the nutrients in the cells and it thus becomes completely uninteresting for both fungi and insects. Furthermore, ThermoWood contains and absorbs very little water, which means that the dimensional stability is increased by 50% leading to a more airtight gap and crack free construction. ThermoWood also has larger pores than untreated wood which increases the insulation capacity by up to 30%. Finally, ThermoWood is lighter than for instance the more commonly used untreated spruce, making it an excellent choice for your lightweight tiny house.
Shou sugi ban (Yakisugi) exterior siding
Shou sugi ban is an old, traditional Japanese method of wood preservation. Instead of heating the wood in a stove (as with ThermoWood, see above) using the traditional technique of Shou sugi ban, the wood surface is directly burned with fire. Just as with ThermoWood this results in a natural, totally non-toxic protection and a more durable facade. Amongst other things the facade acquires a natural resilience against moisture and insects, it is protected against rot and mold and gains an increased dimensional stability leading to fewer cracks and gaps. The big difference between ThermoWood and Shou sugi ban, is their appearance in regards to color and texture. While ThermoWood retains its smooth wooden texture and gains a golden-brown glow, a shou sugi ban facade has a beautiful rough, burned texture and coal dark colour.
Compare all three options:
Choose spruce outer or inner siding if you are looking for locally produced, well performing, cost effective wood used as facade material in all of Scandinavia for many centuries.
Choose ThermoWood outer siding if you are looking for locally produced, durable, beautiful wood that has the same outstanding performance as cedar but for a cheaper price.
Choose Shou sugi ban if you want the same excellent qualities as ThermoWood but with a beautiful rough coal-black surface.
