Details
Klober Uni-Line Slate Vent - Natural & Man-Made Slates - 6,500mm² Free Vent Area is a slate roof vent designed to improve airflow through a pitched roof, helping reduce condensation and prevent moisture build-up in the loft or roof void.
It sits externally at roof level in line with the surrounding double-lap slates and uses an integral downpipe to ventilate directly into the roof space. It is intended for roof-space ventilation at high or low level rather than bathroom/kitchen extraction.
