The three decks of the house are flat. A terrace in the front and two roof gardens above. To optimize the isolation decided to add insulation under the floors of all the covers, although under the garden is not essential, since the soil and plants are an excellent isolation.
With this extra insulation can optimize the performance of bioclimatic housing. But not serve us any material, and that to meet green building criteria, must be sustainable. This insulation must be prepared to support the weight of the mortar Mastro and slopes, which made us discard the hemp . We studied the possibility of using wool, but this material is not suitable for such use, because the weight is pressed flat and loses much of its insulating capacity. After much searching we found the best solution, the cork .
We used Forest-Kork of 30 mm, distributed by Isolana . Are sheets of 1 x 0.5 m of natural agglomerated cork bonded. It has great insulating properties, high compressive strength and low water absorption.
First install the cork boards, being easy to cut allows fit perfectly to the surface. Subsequently installed a geotextile above. Isolana technicians told us that the use of geotextile is not essential, but advisable. So, for safety, we decided to install the geotextile so that the mortar is not in direct contact with the cork. Finally, masons, put the mortar Mastro, on which to install the green roof (garden) in the upper terraces and tile flooring on the front terrace.
