uPVC Windows with Mosquito Mesh: How They Work, Types and How to Choose

Mosquitoes and insects make it hard to keep windows open, especially in warm, humid weather. Closing the window keeps insects out, but it also cuts off fresh air.

uPVC windows with mosquito mesh (also called fly mesh, insect screens or mosquito net windows) solve this by covering the opening with a screen that lets air through while helping keep mosquitoes and other insects outside. How well it works depends on the mesh material, the fit, and whether the screen suits your window style.

Quick Answer

The uPVC window is the frame and the mesh is the insect barrier, so the two must be compatible. Choose the mesh type by window style:

Sliding windows: a sliding mesh shutter on its own track
Casement and tilt & turn windows: usually a fixed or removable screen, planned together with the sash
Wide openings: pleated or roller screens, where the system supports them

Mesh helps with insects. It does not stop fine dust, replace security hardware, or prevent falls.

How Do uPVC Windows with Mosquito Mesh Work?

The profile and hardware carry the glass and operate the window. The mesh, stretched in its own frame or housing, covers the opening so air can pass through while insects are blocked.

The result depends on:

Mesh material and weave: affects airflow, visibility and durability
Fit: gaps at the edges let insects in
Window design: the screen must not interfere with the sash, handle or track
Installation: an inaccurate screen frame is the most common cause of gaps

Types of Mosquito Mesh: Quick Comparison

Type	Best for	Needs space	Maintenance
Fixed	Windows rarely accessed from outside	Minimal	Removable for cleaning
Sliding	Compatible sliding windows	Extra track	Keep track clear of debris
Pleated	Wider, suitable openings	Room for folded mesh	Check the mechanism
Roller	Compatible windows with housing room	Housing and side guides	Check roller and guides

Fixed Mesh

A screen that stays in place. It is the simplest option, with no moving parts. Ask how it can be removed for cleaning and window maintenance.

Sliding Mesh

A framed screen that moves on a track beside the glass panels. It suits compatible sliding windows. Check track compatibility and clearance, since dust and debris collect in tracks.

Pleated Mesh

It folds like an accordion and extends across the opening when needed. Confirm the space needed for the folded mesh and the maintenance of the mechanism.

Roller Mesh

It retracts into a housing and is pulled across when needed. Check the quality of the roller, guides and closing action.

Mosquito Mesh for Casement and Tilt & Turn Windows

Casement windows are among the most popular styles in Indian homes, and they need more planning than sliding windows. When the sash opens outward or inward, the screen has to sit on the opposite side without blocking the handle, hinges or opening angle.

Outward-opening casements: the screen usually sits inside the room. Check that it doesn’t obstruct the handle or curtains.
Inward-opening casements and tilt & turn: the screen usually sits on the outside or in a removable frame. Check outside access for cleaning.
Tilt position: if you ventilate in tilt mode, confirm the screen still covers the opening.

Decide this before ordering the windows. Retrofitting a screen onto a window that wasn’t planned for one is often harder.

Which Mesh Material Should You Choose?

Common mesh materials include fibreglass, aluminium and stainless steel. Each has different strengths, and you should confirm exact specifications with your supplier.

Material	Typical strengths	Things to consider
Fibreglass	Flexible, lightweight, widely used	Can tear or stretch with rough handling
Aluminium	More rigid, holds its shape	Can dent or crease
Stainless steel	Strong and durable	Heavier, usually costs more

Also compare:

Weave density: a finer weave blocks smaller insects but can reduce airflow and visibility
Durability: pets, children and frequent cleaning wear mesh faster
Coastal conditions: ask about corrosion resistance if you live near the sea
Cleaning: how easily the mesh can be removed, brushed and washed

Durakraft Extrusions: A Secure Approach to Mesh Fitting

At Durakraft Extrusions, we offer uPVC window system options designed to accommodate mosquito mesh, including 2.5-track and 3-track configurations with rail profile, depending on the selected system.

One important feature of the Durakraft window system is its dedicated mesh-locking arrangement. This system locks the mesh into the sash, helping it stay firmly in place and reducing unwanted looseness. As a result, the mesh can fit properly within the sash when the compatible components are correctly installed.

In some other window systems, gaskets are used to secure the mosquito mesh inside the sash. Durakraft offers a different approach with a dedicated locking system designed to hold the mesh securely in position rather than relying solely on a gasket-based fitting method.

A properly secured mesh helps maintain a neat fit and reduces the chances of the screen becoming loose during everyday use. The final result depends on the selected window profile, compatible mesh components and correct fabrication and installation.

When choosing uPVC windows with mosquito mesh, ask your fabricator about the available 2.5-track and 3-track options, rail profile compatibility and mesh-locking mechanism.

Benefits of Mosquito Mesh on uPVC Windows

1. Ventilate Without Leaving the Opening Exposed

A well-fitted screen lets you open windows in the evening without letting insects in.

2. Airflow and Visibility

Mesh passes air and keeps the view mostly clear. Actual airflow depends on the weave and screen area.

3. Options for Different Windows

Fixed, sliding, pleated and roller systems let you match the screen to your window.

4. Easy Cleaning

Mesh can usually be brushed or vacuumed, and many frames are removable for washing.

What Mosquito Mesh Does Not Do

It does not stop fine dust or pollution. Mesh openings are far larger than dust particles. If dust is your concern, see our guide on whether uPVC windows reduce dust and pollution.
It is not a security barrier. Security comes from locking hardware, reinforcement and glass. See our window security features guide.
It is not a fall-prevention device. Standard insect screens do not support a person’s weight. For homes with children, ask separately about opening restrictors or safety solutions.

How to Choose the Right Mosquito Mesh

Window type: sliding, casement, tilt & turn or fixed
Measurements: the screen should fit the opening with minimal gaps
Material and weave: compare airflow, visibility and durability
Space: pleated and roller systems need room for the mechanism
Compatibility: it should not interfere with the sash, handle or track
Existing windows: have a professional check whether a screen can be added

Avoid common buying mistakes such as ordering on price alone or skipping a site measurement. See our 10 mistakes to avoid when choosing uPVC windows and doors.

Why the uPVC Profile Matters

The profile determines how the window is assembled and how hardware, glass and seals fit. For mesh, it also affects whether there’s a track or mounting space for the screen.

At Durakraft Extrusions, window profiles are developed as systems. Sliding systems in the Premia Series (DK 50, DK 80 and DK 90) are used for sliding and casement applications, and our 2026 window designs guide notes mesh compatibility in applicable systems. Profile manufacturers, fabricators and mesh suppliers may be different parties. Ask your fabricator whether the screen fits the chosen frame, what extra tracks or space it needs, and how it is maintained.

Frequently Asked Questions

Do uPVC windows come with mosquito mesh?

Not automatically. Some systems can be fitted with mesh, but it isn’t included with every window. Check the specification with your supplier.

Which mosquito mesh is best for uPVC windows?

It depends on your window. Sliding mesh suits compatible sliding windows, while casements and tilt & turn windows usually need fixed or removable screens. Fixed, pleated and roller systems suit different opening designs.
