Developing an airy timber frame wall

An integral building concept is developed based on industrial produced, lightweight, load-bearing wall panels. The leading idea is to apply I-shaped studs combining structural solidity, thermal comfort, integrated piping and simple lightweight assembly. The I-shaped stud mainly consists of two fir laths 30x46 mm2 at intervals of 400 mm. Combined with hardboard and insulation makes a solid wall with impressive buckling loads (full-scale laboratory tests found an average axial load of 176 kN/m’ at buckling length 2.8 meter although the total dead weight is just 0.45 kN ~ 7.1 kg/m2). The composite load-bearing wall consists of approximately 3-5% solid substance and 95-97% stationary air and yet it seems to be suitable for a 3-story dwelling even when applying massive concrete floors. Since the composition of the wall panel is based on using durable materials and allows for full industrially manufacturing the integral building concept is meant to be preparatory for future house building.
