Klober's 20K Slate Vent KG9795-0429 in Slate Grey provides high-level ventilation with 20,000mm² of ventilation space. Preventing mould growth and structural damage caused by damp, poorly ventilated roofs.
The Universal 20k Slate Vent suits larger man-made fibre cement and natural double lap slate tiles (600mm x 300mm / 24” x 12” and 500mm x 250mm / 20” x 10” tiles) with a minimum pitch of 22.5°. The Universal 20k Slate Vent is available in slate grey or dark slate to blend in with the roof tiles. KG9795-0429.
Installing a 20K Slate Vent
To accommodate the downpipe, cut a hole in the roofing underlay and place the Slate Vent. Use Klober underlay seal to maintain the underlay's integrity. Nail the rigid base on each side of the batten. Cut the profile of the vent body into the two slates immediately above the Slate Vent to ensure a proper fit.
Notice: When using 500mm x 250mm (20" x 10") slates we advise to detach the front section of the Slate Vent base by following the guidelines on the underside. Cut the adjacent slates on the same course and the slate directly behind the Slate Vent to fit. Clip the Slate Vent base with a slate rivet.
