The design of the dome house was developed with great care and attention to detail. It takes into account not only environmental concerns, but, above all, is a kind of combination of a return to nature and modern technology.
The outer structure of the building is formed from prefabricated modules, which are made at a specialized plant. The assembly of individual modules into the form of a dome is carried out directly on the construction site.
The prefabrication technology adopted is a guarantee of accuracy and short construction time. An additional advantage is that a dome house in our technology can be erected practically at any time of the year.
The construction of individual modules consists of spatial wooden trusses, the elements of which are joined together using both traditional carpentry joints and modern methods. The modules are connected by special locks. The filling of the wooden structure of the modules is wood wool or hempcrete.
STEICOflex 036 resilient mats are used to fill voids in roof, wall and ceiling structures. Produced from fresh softwood without harmful additives, they are neutral to human skin.
Best protection against heat loss in winter, acoustic insulation. STEICOflex 036 has the lowest thermal conductivity coefficient – λD 0.036 [W / (m * K)], among all known natural thermal insulation materials. It is characterized by a particularly high volumetric density, making it an effective protection against noise.
Healthy indoor microclimate, diffusion openness
STEICOflex 036 is produced exclusively from fresh wood sourced from local, responsibly managed forests, is a vapor-permeable material, i.e. it allows moisture to escape safely. In simplified terms, the term “breathable construction” is often used. If moisture enters the structure, it can dry quickly and the building structure will remain permanently protected from the damaging effects of moisture.
The best protection against summer heat.
Wood fiber materials are distinguished by the highest heat accumulation of all commonly used thermal insulation materials.
Hempcrete is a lime and hemp composite, consisting of cut pieces of industrial hemp stalk (hemp shive) mixed with a lime-based binder. It is a natural, healthy, sustainable, local building material with low embedded energy.
Hempcrete is a good thermal insulator, is non-flammable and resistant to fungal and mold growth, and hardens over time. By binding CO2 from the atmosphere, it becomes calcium carbonate, or limestone rock.
It has sound insulation properties and incredible heat capacity. It is a material containing cellulose – its ability to accumulate heat is far greater than in materials such as mineral wool.
It provides thermal stability – we have warm walls from the inside, and heat loss is limited because heat penetrates the walls more slowly, and we save on energy costs.
Reducing energy costs
Hemp concrete has very good thermal properties, so it is no longer necessary to use additional thermal insulation. This creates excellent thermal insulation properties of this building material and ensures thermal comfort inside the building.
The lime contained in hemp concrete is an antiseptic material. Lime has a high pH and is inherently antibacterial and antifungal, and the lime coating around each piece of hemp in the mix, creates a surface that resists mold growth, even when moisture and temperature conditions would cause mold on other insulation materials. It is free of chemical contaminants.
Natural air conditioning
The high vapor-permeability of this building material allows the walls to breathe, which protects against damp rooms. Hemp concrete regulates the temperature and humidity in the house providing an optimal microclimate.
Very durable building
Hemp concrete interacts with the wooden structure, so to speak, in symbiosis. The wooden structure provides concrete with support, and hemp concrete protects the wood: it allows it to breathe – which ensures the long life of wooden elements The combination of hemp shavings with alkaline lime prevents the development of mold, fungi and possible colonization by insects and rodents. Hemp concrete is subject to carbonization turning gradually into calcium carbonate(lime rock)
Hemp concrete is non-flammable, protecting the wooden structure from fire. When subjected to continuous fire, it shows little change in overburning and has been classified as a fireproof material.
Hemp concrete is a natural, environmentally friendly material is fully recyclable after use. Compared to other building materials, we need much less energy to produce hemp concrete, so it is a low recycled material.
As a plaster for the interior of the dome, we recommend clay plaster because of the numerous pro-health properties of clay as well as the diffusivity that harmonizes with hemp concrete. We can paint such walls with natural diffusion paints obtaining any color from the color palette. Another proposed solution is the use of lime plaster or interior wood board.
