Hemp has a U-value of 0.40, which outperforms other insulating materials like wool and cotton. In double masonry, the hemp blocks are adapted to envelope the load-bearing masonry made of concrete, terracotta, aerated concrete or silico-calcareous materials. We will support you in your sustainable and efficient project, while guaranteeing a controlled budgetary envelope. This storage capacity allows the material to absorb excessive moisture and release it when the conditions allow. Simply lay the blocks in staggered rows on the floor and then add a layer of reinforced screed (minimum 6 cm thick). It is also suitable to support a screed such as cement, lime or clay. By applying to the exterior of the wall of a home, it can achieve a high insulation performance for the entire structure. What is the typical thickness of hempcrete for walls? Contact us to find out which solution would be most suitable for your building ! Thus, a coating of lime binder around the hemp hurds creates a resistance to the development of molds. It also acts as a natural insulator to keep the interior temperatures controlled no matter the season. It is also known as hemp lime. A floor insulation without any settling over time and with a real insulating adhesive / screed ! The moisture from the air gets accumulated on the large internal surface of the plant fiber and gets absorbed into its cellulose structure. Result? Laying insulation for an entire building in just a few hours. Whether the load-bearing structure in column-beam systems is made of wood, steel or concrete, hemp blocks can be used to create insulating and breathable single walls that do not require the use of any other insulating material. The use of hemp blocks on the ground allows the slabs to be insulated and is suitable as a support for a screed. Hempcrete acts as an incredible material when it comes to insulating the roof of buildings. You can opt for manufactured blocks because their application is quick and easy and the insulation prevents the roof from overheating during summers. The uniqueness of hempcrete among the plant-fiber insulation materials is its ability to maintain its standard in humid conditions. The construction of a sustainable and efficient building made of hempcrete blocks has never been so simple: with a single insulating material, build a custom-made project.
