The advantages of single-leaf masonry
Thermal inertia – heat capacity
The special hole pattern, combined with high heat capacity, reduces heat losses and increases thermal inertia: the wall becomes an energy “store”. In winter, solar gains are used for many hours; in summer, the coolness of night ventilation is retained.
Thermal insulation
The increased insulating capacity reduces the need for additional insulation, meeting KENAK requirements in the best and most economical way. Thermal properties have been calculated and optimised with modern simulation methods.
Ideal microclimate
Thanks to the porosity of their mass, bricks act as humidity regulators: they release moisture when the air is dry and absorb it when it is humid.
Combined benefits
Better indoor climate, heat storage and thermal insulation, earthquake resistance and increased fire resistance – essential qualities for bioclimatic buildings and total-quality constructions.
Single-leaf masonry, i.e. masonry made of thick bricks with high thermal resistance, has significant advantages over any other form of construction: excellent earthquake and fire resistance, significant sound insulation and remarkable thermal insulation, which, combined with high heat capacity and relatively low cost, make it a unique building element for low-energy buildings. During an earthquake it performs much better than double masonry with a cavity.
