DEKS Flat Roof Vents are cleverly engineered to remove trapped moisture and vapour from flat and low-slope roofing systems, promoting continuous airflow between the concrete slab and roofing membrane to prevent condensation, dampness, and structural damage. Designed for modern construction environments, these flat roof aerators help to prevent trapped moisture, reduce condensation, and extend the life of the waterproofing system.
Its enlarged base design accommodates both Ideal H160 and H400 models, allowing connection to ventilation ducts with external diameters of up to 125mm - offering flexibility for a wide range of roof configurations. For optimum results, it is recommended to install three to four aerators per 100sqm. The DEKS Flat Roof Vent can also function effectively as a ventilation duct, particularly when used alongside the Estraer double trumpet cover for enhanced air movement.
Constructed from high-grade, weather-resistant materials, the DEKS Flat Roof Vent provides exceptional durability and chemical resistance, even in extreme temperatures. Its robust mechanical properties remain stable over time for reliable performance in harsh UK conditions. The ribbed flange base ensures a secure fit, while the quick-locking cover system provides a safe, airtight installation. Together, these features make DEKS aerators the ideal solution for continuous vapour discharge and long-term roof protection.
