Open utility ducts in apartment buildings and commercial properties frequently collect pigeon droppings, feathers, and nesting debris. This accumulation can cause unpleasant smells near ventilation windows and obstruct drainage pipes. Poorna Enterprises installs durable, UV-treated safety nets across building shafts throughout Chennai to restrict bird access while preserving airflow and natural light.

Poorna Enterprises provides customized duct area safety netting for residential apartment communities, commercial offices, and multi-story buildings across Chennai. Each installation is planned according to the shaft dimensions, ventilation needs, and structural fixing points.
Building utility shafts (lightwells) house wastewater pipes, electrical conduits, and air conditioner compressor lines. When left uncovered, these shafts present several practical challenges for residents and facility managers.
Pigeons naturally seek out narrow, wind-protected ledges. Over several months, accumulated nesting materials, twigs, and feathers can litter bottom collection areas and create maintenance difficulties.
Bathroom exhaust fans and kitchen windows often vent directly into the utility duct. When droppings accumulate in enclosed vertical shafts, unpleasant odors can drift back through open window louvers.
During heavy monsoon rains, feathers and loose debris at the bottom of the duct shaft can wash into drainage grating, contributing to waterlogging and localized seepage.
Outdoor AC condenser units placed on shaft ledges are exposed to bird droppings. The acidic content of droppings can corrode aluminum heat-exchange fins and deteriorate pipe insulation jackets over time.
Deep shafts with multiple stories are hazardous and expensive to clean manually. Installing a durable physical net creates a barrier that prevents continuous debris build-up.
Netting physically excludes birds from entering and roosting without using chemical repellents, sticky pastes, or harmful traps.
A safety net acts as a physical exclusion barrier drawn tautly across the open shaft aperture, either at the rooftop level, external vertical face, or both.
The installation involves securing a continuous stainless steel perimeter cable along the concrete structural beams using expansion anchors and heavy-duty turnbuckles. The net is then fastened uniformly to this perimeter framework using stainless steel rings.
Because the net is tensioned evenly, birds cannot squeeze through the edges or find stable landing perches on the mesh. At the same time, the 25mm to 30mm square mesh preserves open airflow, ensuring that bathroom exhaust, kitchen ventilation, and natural daylight pass through without restriction.
The choice of material depends on sun exposure, building height, coastal salinity, and specific property requirements.
Constructed with high-tenacity multifilament nylon treated with ultraviolet stabilizers. Offers high tensile strength, good elasticity under wind load, and a translucent appearance that blends into building elevations.
Monofilament plastic netting that does not absorb moisture and resists chemical breakdown. Well suited for industrial premises and commercial lightwells where water resistance is important.
A rigid wire barrier made from Grade 304 or 316 stainless steel. Ideal for specialized installations where both rodent and monkey exclusion or extra mechanical protection are needed.
Chennai’s coastal climate carries airborne humidity and salt, especially in areas like Adyar, Mylapore, Besant Nagar, and along the OMR corridor. Low-grade iron wires or zinc-coated screws can corrode over time. Poorna Enterprises uses stainless steel wire ropes, turnbuckles, and anchors to maintain structural stability.
How our team plans, rigs, and completes duct netting projects safely.
Our technicians inspect the shaft access, measure opening dimensions, check concrete anchor points, and identify external AC pipes or plumbing risers.
Anchor bolts are fixed into solid structural concrete at regular intervals. A stainless steel perimeter cable is routed and tensioned using turnbuckles.
The UV-treated net is positioned across the opening and securely clamped loop-by-loop to the perimeter wire rope with stainless steel fasteners.
Where AC compressors or plumbing joints require regular servicing, accessible zipper flaps or removable panels are incorporated for technicians.
Responsible installation requires balancing bird exclusion with building serviceability.
A safety net should never block required building ventilation. Standard 25mm to 30mm mesh allows air to circulate freely from bathroom exhaust fans and kitchen vents, preventing heat accumulation.
Air conditioning technicians need periodic access to service outdoor compressor units and refrigerant lines. Installing zippered access panels ensures technicians can work without cutting the net.
While UV-treated netting requires minimal day-to-day care, building associations should conduct periodic visual inspections after severe weather or major building exterior painting.
Because duct dimensions and site conditions vary considerably, quotes are provided after assessing the property.
In Chennai, basic netting rates typically start from ₹18 to ₹28 per square foot for standard residential installations, depending on material quality and fixing hardware. Key factors that determine final pricing include:
