What effect does lack of air space have regarding wall claddings?

Lack of air space behind wall claddings primarily leads to water accumulation and moisture issues. When there is insufficient air space, moisture that may enter the cladding system has limited ability to evaporate. This trapped moisture can lead to a variety of problems, including mold growth, deterioration of materials, and even structural damage.

Adequate air space is crucial in allowing for ventilation, which helps to dry out any moisture that may seep in. Without this ventilation, moisture can accumulate, leading to an environment conducive to rot and other moisture-related issues. Therefore, considering wall cladding installations, ensuring an appropriate air gap is essential to maintaining the integrity and longevity of the wall system.
