– Rytons External Weather Louvres –

Made-to-measure from galvanised steel and available with or without mesh screening, Rytons A1® Fire-rated External Weather Louvres allow air to flow efficiently into or out of a building or HVAC system.

With an A1 fire rating, these heavy duty air intake and exhaust grilles are suitable for use in high-rise buildings and any other building requiring screened ventilation – we know of applications in plant rooms, bin stores and even a cow shed! 47mm deep and fitted with 45° fixed open louvre blades, both Rytons plain and mesh options allow valuable ventilation with protection against water ingress.

Made to order, Rytons External Weather Louvres are available in all sizes, large or small – previous commissions have ranged from 195mm x 195mm to 1585mm x 1430mm and many in between. Finished in a custom Class A2-s1, d0 powder coating, choose any colour from the RAL Classic colour chart or a signature architectural finish to ensure the grille blends with the exterior for a clean, aesthetic appearance.

  • 45° angled louvre blades allow effective airflow and weather protection.
