Introduction

The upgraded CSV Circular Soffit Ventilator may be introduced into new soffits or existing soffits. It permits easy and quick upgrading of existing structures. The unique injection moulded ventilator has a deflecting louvred face, promoting positive air entry and insect screening. Unlike standard ventilators, the unique CSV may be rotated so that the louvres slope downwards towards the masonry face. In so doing, no visible apertures/grilles are apparent to the eye and the result is of a continuous unpenetrated soffit, when a CSV of a matching colour is fitted. This ventilator has a greater air throughput than most models, and fewer are required per metre run to satisfy requirements. Rectangular version also available with free airflow of 7500mm2.

Use

Circular Soffit Ventilators with louvres, for new and existing work. Ventilators promote the entry of air into the roof space.
