Limestone and sandstone facades are permeable, porous and matt: what more could you ask for in an external cladding.
Both types of stone possess a series of physical-mechanical characteristics that gives them highly-valued properties in construction for the cladding of ventilated or bonded facades: their low thermal conductivity allows them to act as insulators in extreme weather conditions, while their high bending resistance allows thicknesses to be reduced, making structures lighter.
Limestone and sandstone panels are used in external walls of family houses, blocks of flats and hotels, as well as in shopping centres and office buildings. The uniformity of the stone makes it an alternative that is aesthetically much sought-after.
-
Building facades with an identity of their own
-
Subtle integration into urban architecture
Major avant-garde architectural projects for public works such as auditoriums, theatres and conference centres have been clad in this stone, especially in its lighter hues. However, the ochre and yellow hues of sandstone are also highly esteemed among constructors.
