In modern times, most of the people are fascinated with 3D printed houses, but if you have fondness for wooden homes, then French startup Catharhome has something interesting for you. The company has come up with Brikawood, Lego-inspired wooden bricks that interlock over each other with spacers, and require no nails or glue while building a house or structure.
This innovative idea is the brainchild of engineer Alain Romero who researched for three years to develop it with the help of Patricia Dutreux. Made of sustainably-sourced Douglas fir, it works similar to traditional toy Lincoln logs consisting of miniature logs used by children to make tiny forts.
This Lego-inspired wooden brick comprises four wooden elements – two lateral flanges and two transversal spacers with dovetail joints, assembled by interlocking over each other, thus giving a mechanical rigidity to the structure. A rubber hammer is used to mount bricks in dedicated slots and a drill is used to secure the sill plate on the slab. You’ll also need a wall cap to close the walls after complete insulation.
The Brikawood brick is designed to be used alone, without any cladding and membranes. It just needs to be equipped with an anti-return valve specific to Brikawood to ensure the tightness of the construction that helps minimize heat loss for the same level of comfort in summers and winters. The hollow parts between wooden bricks are filled with wood shavings or cellulose wadding (paper recycling) for thermal insulation.
Brikawood can withstand earthquakes measuring 8.5 on the Richter scale. Even if you are completely new to the building industry, this innovative Lego-like material eases the task of building your own house. With its help, you can build a modular, energy-efficient house easily.
Brikawood passive house
Brikawood passive houses are a mixture of reinforced insulation, glazed windows, heat recovery ventilation system, air-tightness, solar system, and low energy appliances. They consume 90% less energy than most existing buildings, and 50% less than new homes according to the most current thermal regulation standards. It also employs a double-flow controlled mechanical ventilation (CMV) system to minimize heat losses due to ventilation. Meaning, it helps minimize energy bills by maintaining pleasant temperature without conventional heating in winters and air conditioning in summers.
The roof of Brickawood passive house is also made in wood using an innovative system of small traditional latches, on which a tile cover or an insulated steel casing can be layered for better performance. The ceiling also uses wood paneling fastened under the latches, with a 30 to 40 cm thick layer of the wood fiber. These wooden bricks maintain a constant temperature between 19 to 21-degree.
The bioclimatic design creates an effective envelope in summer as in winter, excellent airtightness with a target value lesser to n50 and equal to 0.6 h, the standards required for a passive house certification.
While building a house with these interlocking bricks, you need to construct on stilts so as to eliminate the risk of moisture from the ground as hollow spaces between bricks are filled with filtered wood chips, blown wool or cellulose wool for better insulation. For the base, you can choose between Techno Pieux and concrete foundations.
Brikawood is available in two types – Brick 250 and Brick 160, which can be used to construct different types of houses. Simple and faster construction along with additional benefits of tightness and high thermal performance are highlighting features of a passive house made from Brickawood. The price range for Brickawood passive houses lies between $74,678 to $149,984, depending on the model you choose.
