COMPARATIVE TESTING

In comparative testing, CertainTeed’s MemBrain outperforms traditional vapour retarders by dynamically adjusting its permeability based on humidity levels. Unlike conventional barriers that remain fixed, MemBrain allows moisture to escape during high humidity, preventing condensation and reducing mould risk. Testing also shows MemBrain maintains a tight seal in low humidity, effectively blocking moisture entry. Its advanced moisture management capabilities make it a superior choice for enhancing energy efficiency and protecting building envelopes in diverse climates.
