Dry Facade vs. Wet (Mortar) Facade — A Real Site Perspective
Why are dry facades (dry ceramic, HPL, composite) replacing mortar-set cladding? A comparison of safety, weight, execution speed and total cost from a team that has executed both systems on real sites.
In a wet, mortar-set facade, the cladding material — stone, brick or ceramic — is bonded to the building with mortar. These systems have been common for decades, but they carry serious, well-documented risks: pieces of the cladding can detach and fall, the dead load transferred to the structure is heavy, and there is no ventilation behind the facade, so moisture stays trapped against the wall.
Dry facades connect the cladding mechanically — brackets, rails and clips — and deliberately leave an air cavity behind the panels. That single decision produces three fundamental advantages: far higher safety against falling material, a lighter dead load on the structure, and the ability to install thermal insulation that actually performs, because the ventilated cavity keeps the insulation dry and lets the wall breathe.
And the cost? If you calculate the total life-cycle cost — repairs, energy consumption and durability, not just the invoice — dry facades are more economical in the majority of large projects. Our site experience of executing hundreds of thousands of square meters of facade adds one more observation: quality control is easier to standardize in dry systems too. Every bracket, rail and clip can be inspected and signed off; a mortar bed hidden behind a stone slab cannot.
