Navy Blue Ventilation Window

Product Overview

This navy blue ventilation window is a side-wall air exchange unit for poultry houses, shown fitted in the photo as a long rectangular window with two clear zones: a screened grille in the middle and a solid curved hood below. The screen zone keeps insects, birds and leaves out while letting air pass, and the lower hood shapes the air path so drafts are spread gently rather than blown straight into the birds. The label on the drawing reads specification: ventilation window, confirming its role as a general side-wall ventilation unit.

The whole unit is moulded in navy blue engineering plastic and fixed to the wall with bolted side flanges. There are no visible motors or blades, so it works as a passive window balanced with exhaust fans or as an exhaust-side opening on naturally ventilated barns. Its long, low shape suits the high side walls typical of poultry sheds, where a wide but shallow opening moves air without taking away wall height.

Key Features and Benefits

• Insect mesh screen - the centre grille area keeps flies, moths and leaves out while air still flows through.
• Curved rain hood - the lower solid hood shields the opening from driving rain and shapes the outgoing or incoming air path.
• Long low profile - the wide rectangular window suits high poultry-house walls and spreads air over a long wall section.
• Bolted side flanges - the flanges at both ends fix the window firmly to timber, steel or concrete walls.
• All-plastic navy body - no metal parts to rust, and the dark colour stays neat on an outside wall for years.
• Passive operation - works with natural cross ventilation or balanced with exhaust fans, with nothing to power or service.

Materials and Quality

The window frame and hood are moulded from navy plastic chosen for outdoor wall exposure, where it faces sun, rain and frost without cracking or fading badly. The mesh screen is fixed inside the frame so it cannot be pushed out by birds or poked by cleaning tools, and the hood lip is thick enough to hold its curve in strong wind. Because the unit has no bearings, seals or blades, the quality check focuses on frame strength, screen fixing and flange flatness before cartons are sealed for export. The navy colour hides dust streaks better than white plastic, so the outside wall still looks tidy after a dusty dry season, and the hood lip channels rain down and away instead of back toward the opening.

How to Use and Maintain

Fix the window onto the prepared side-wall opening with bolts through the end flanges, and seal the edges if your wall type needs it. For naturally ventilated houses, leave the window open as the main air exchange point; for fan houses, balance it against the exhaust fan rate. Between flocks, brush dust and cobwebs off the mesh from the outside, and hose the hood clean. If the mesh gets torn, replace the screen section rather than the whole window. In dusty regions, brush the mesh more often than once a year: a clogged screen reduces air flow far more than farmers notice, because the house slowly relies on fan power instead of balanced openings. A quick visual check of the mesh once a month avoids this slow drift.

Applications

This ventilation window is installed on the side walls of meat-chicken houses, layer barns and breeder sheds that need a wide, insect-proof air exchange point. In warmer regions it often works as the main opening in a cross-ventilated house, while in colder regions it is paired with exhaust fans and used only in part-opening modes. The insect mesh is valuable wherever flies are a problem, because screened walls cut fly entry without stopping airflow.

It also suits farm outbuildings, hatchery corridors and equipment rooms that need simple wall ventilation, as well as livestock barns converted from poultry sheds. Distributors can offer it as the passive window option in a ventilation range that also includes power fans, cooling pads and adjustable air inlets, covering every house style their customers run.

Frequently Asked Questions

Q1: Does this window come with an exhaust fan?

No. This is a passive side-wall window. It works either on naturally cross-ventilated walls or balanced with your existing exhaust fans; we can quote fans separately if needed.

Q2: Does the mesh stop flies from entering the house?

The mesh screen covers the centre air area, which greatly cuts insect entry compared with an open window. Keep the mesh clean so air flow is not blocked by dust build-up.

Q3: Can it be installed on a steel-structured wall?

Yes. The bolted end flanges fix to timber, steel framing or block walls with suitable fasteners. Tell us your wall type and we will suggest the fixing method.

Q4: How is the window packed for export?

The plastic windows are packed flat in strong export cartons to avoid scratching the navy surface, and cartons are stacked for container loading. Mixed loads with fans and inlets can be arranged.
