Our variable window vents have been designed with flexibility in mind; allowing the option to partially close the vent enabling a comfortable flow of natural ventilation.
Suitable for use where a high level of equivalent area is required and to achieve the minimum room requirements under the latest Building Regulations (between 4000mm² EA and 10,000mm² EA depending on the room and type of dwelling).
Some models are able to be installed with the option of two equivalent areas (2000/2500mm² EA or 5000/5500mm² EA) meaning lower stock requirements.
Variable control allowing users to fully or partially close the internal vent to achieve the desired flow of natural ventilation.
Manufactured from tough and strong ASA plastic which is known for high impact wear and UV resistance - minimising the risk of discolouration and weathering.
Excellent air tightness performance, increasingly important with dwelling air pressure tests.
Aesthetically pleasing design – unobtrusive when installed.
Optional installation mechanism using the provided fixing clips or fixing screws.
Available in a range of colours (including special RAL colours via request).
