Walls define the interior space of the house and, together with the ceiling and floor,
constitute our “third skin” next to our clothes. It is very important how we treat this layer,
particularly if we live in a cooler part of the Earth where more than half of our life is spent in
the interior environment.
There are many factors applicable to wall assessment. The most important
information on walls includes the height, load-bearing capacity, or the interior and exterior
finish. Walls can be plain white, with rough wooden patterns, glossy, transparent, soft, or
sliding. This complex topic has been narrowed down in this tiny house construction guide to
cover primarily technical details one must know when intending to build a tiny house.
- Sheathing – acts as bracing for the entire structure and
protects the interior layers of the wall at the same time.
However, it is not mandatory.
- Battens – fixing the hydro insulation to the supports, and
creating ventilation space.
- Rainscreen – hydro insulation against exterior dampness; the layer should also be capable of letting through any moisture from the inside of the wall
- Exterior cladding – protects the building from exterior weather
influences and has an aesthetic function.
- Installations – this part of the structure accommodates the power, water, sewerage and other mechanical installations.
- Plate – part of the load-bearing frame
- Stud – part of the load-bearing frame
- Interior deck – aesthetic function; covers the installations behind it.
- Battens – holding the vapour barrier and creating space for installations
- Bracing – makes the structure more rigid and prevents undesired movements. The same function is served by the sheathing.
- Breathable membrane – prevents interior moisture from leaking into the
thermal insulation. Moisture is transported in the other direction.
- Thermal insulation
If the foundations and the board that forms the first upper storey floor are ready, the
time has come to start on the load-bearing structure of the walls which will support the floor of the second storey or the roof structure. The load-bearing wall structure is accompanied by other components depicted in the picture on the next page. This chapter will summarise the basic construction principles for various types of walls, with an emphasis on wooden houses. We will explore individual material and aesthetic solutions of the façade and interior. There are many types of walls so the most important types best suited for tiny house construction have been selected for this book.
