Sewn Structure



In the Andean countries there is a millennial construction tradition called Quincha. This technique consists of interweaving canes into a vertical frame and then applying a mixture of earth and straw. This system is still used today, not only in Peru but throughout the world (there are many people who are rebuilding with ancestral techniques). I propose MetsaWood to offer to the market strips of plywood because it can normalize this constructive system. Strips are not nailed or glued, they are kept in the position that one leaves them by the tension to which they are submitted. They must have a separation between them so that the mixture of earth and straw cross from side to side. The application of the mixture is very easy. It is made by hand. It should be allowed to dry sufficiently until all the natural drying cracks occur. Then proceed to apply a plaster with finer texture. Another option of this sewn structure system is to leave the strips in sight, as an aesthetic option. If you want a wider strip, we will have to opt for a plwood thin enough to allow interlacing (this is also an aesthetic option).
