Ventilation & Sun Louvers
Louver blades angle to let air through while blocking direct sun and driving rain — used on plant-room ventilation, service openings, and as a shading layer over glazing on a west-facing elevation. The blade angle is a trade between airflow, shade and privacy, and it has to be picked for the specific opening.
What matters about this product
- Cuts direct heat gain.
- Angled blades block direct sun while still letting air move — genuinely useful on a west or south-facing Lucknow elevation through summer.
- Fixed or operable.
- Fixed louvers for permanent ventilation openings (plant rooms, shafts); operable blades where the airflow needs to be adjusted or shut.
- Durable aluminium construction.
- Resists corrosion and holds its finish outdoors better than a painted MS louver over time.
- Reduces view through, by design.
- Louver blades restrict a clear line of sight — right for privacy and utility screening, not for an opening where an unobstructed view matters.
- Blade pitch trades airflow for weather protection.
- A tighter blade pitch keeps out more rain and gives more privacy but cuts airflow more too — this has to be matched to the opening's actual job.
- Custom sizes and shapes.
- Fabricated to the opening rather than off a fixed stock size, including door-height louvered panels for shaft access.

Questions people actually ask
Do louvers let rain in?
A well-pitched blade angle sheds most driving rain while still passing air, but louvers are not fully weatherproof the way a sealed window is — they're specified for ventilation openings, not habitable-room glazing.
Can I see through them?
Only partially, and that's usually the point — louver blades are angled to block a direct sightline while still passing air and light, which suits plant rooms, service shafts and privacy screening.
Fixed or operable — which do I need?
Fixed louvers suit permanent ventilation openings that never need to close, like a plant room vent. Operable louvers suit anywhere the airflow needs to be adjusted or shut off, such as sun shading over a window.
Can louvers be used as sun shading over an existing window?
Yes — a louvered screen mounted outside a glazed opening cuts direct heat gain on the glass, which is a common use on west-facing rooms.
