I want to build a house in the standard RT2012 Monomur terracotta. What do you think?
The regulation takes into account 3 criteria:
- The thermal resistance, that is to say the capacity of a wall to avoid thermal losses - The inertia or the capacity of a material to store the heat and benefit from the free solar contributions - The watertightness to the to prevent parasitic air leakage
Many airtightness measures have been made in Monomur terracotta houses and the results are excellent, well below regulatory requirements (0.6m³ / h / m²).
Moreover, because of its weight and nature, the Monomur is a material that offers great inertia and plays an important role in the reversible thermal comfort summer / winter. The Monomur reduces temperature variations, it plays in fact the role of natural air conditioner.
Finally, the thermal resistance of the Monomur (R), which varies from 3 to nearly 4, obviously makes it possible to build homes in accordance with the RT 2012, in other words the BBC criteria. The Monomur is used to efficiently treat thermal bridges between the facade and the intermediate floor.
Attention: the implementation of the Monomur requires care (laying of the 1st rank, implementation of blocks in a joined way, use of accessories); make sure that your mason knows his specificities and the requirements of thin-joint installation.
