THE door industry journal summer 2025 94 Doorsets, Fire Doors, Safety & Security Also online at: www.dijonline.co.uk Balancing Air Movement and Fire Safety: The Important Role of Fire Block Louvre Systems Allegion UK, a leading name in fire safety hardware with a trusted reputation for keeping people safe where they live, learn, work, and connect, discusses the importance of adequate ventilation and combining air movement with fire protection when both are needed. Supplier of the Zero L-700-RX Louvre and the FBLS Fire Block Louvre System, Allegion UK offers an extensive range of innovative fire door hardware designed to improve the effectiveness of fire doors in containing the spread of fire, smoke and heat. Healthy Ventilation It’s estimated we now spend ninety per cent of our time indoors, so it’s never been more important to consider the quality of our indoor air. Essential for good health and productivity, breathing in good quality air matters. Poor air quality, typically characterised by high levels of pollutants or inadequate ventilation, can lead to unwanted health issues, such as respiratory problems, allergies, and headaches. Poor air quality can also have a negative impact on concentration levels and productivity, making it a real concern for workplaces and educational settings. From the Volatile Organic Compounds (VOCs) found in many commercial and household products to a build-up of carbon dioxide, indoor air can be of significantly poorer quality than outside air if buildings are not adequately ventilated. Louvres offer an excellent ventilation solution, yet they also allow smoke and fire to pass through along with air. Iain Banks, Product Marketing Manager at Allegion UK, commented: “When improved ventilation and general airflow are needed around a building, fitting a door louvre will help to eliminate excess moisture, disperse indoor pollutants and control temperatures. By using the natural forces of wind and temperature differences, passive airflow can be created through intentional openings in doors. Metal louvres are ideal for doors in offices, classrooms, or in doors to plant rooms, stores, computer rooms, changing facilities, and manufacturing areas where air circulation is required. However, where air can pass, so can smoke and fire. If your door demands ventilation and fire protection, you need a Fire Block Louvre System.” The Benefits of Natural Ventilation • Improved air quality & energy efficiency • Reduced pollutants in the air • Reduced excess moisture, decreasing the risk of mildew & mould growth • Removal of harmful VOCs & the build-up of carbon dioxide • Reduced potential health issues • Improved concentration, focus & productivity • Improved comfort & sleep quality • Reduced number of sick days taken • Reduced spread of respiratory infections Iain continues: “Suitable for factory fitting or retrofitting in doors ranging from 29mm to any thickness and with a 50% free area (the amount of space available for the air to pass through), the Zero FBLS Fire Block Louvre System is designed to provide ventilation while also offering fire protection. Featuring an intumescent fire block that expands under high temperatures to seal the door space and block airflow, the system offers protection against fire and cold smoke, making it the ideal solution for fire-rated doors to rooms that require ventilation.” To learn more about the Zero L-700-RX Louvre and the FBLS Fire Block Louvre System, visit zeroplus.co.uk or contact their knowledgeable team at 01785 282 910. www.allegion.com Sources: https://www.verywellhealth.com/air-pollution-headache-7566891 | https://www.buildinggreen.com/blog/we-spend-90-our-time-indoors-says-who
