Cembrit CemVent 600mm x 300mm Slate Vent (Grey / Green)Please note, this CemVent does not come with slate included. CemVent is probably one of the most versatile Natural Slate Ventilators available on the market today. CemVent will match perfectly with any slate simply by using a piece of the same slate, cut on site and fitted into the bottom section. No unsightly plastic mushrooms to spoil the roof, just a discreet grill, coloured to blend into the finished roof. CemVent can be used for the termination of soil vents or extractor fans (with optional flexi pipe) or to simply ventilate the roof void. Developed by one of Europe's foremost producers of roof ventilation products, CemVent is manufactured from UV stabilised material, using design technology developed proven and tested during more than 30 years of experience in this specialised field.
