The Complete Guide to Insect Screens for Garden Route Coastal Homes
Why standard insect screens fail in salt air and what actually works for Knysna, Plettenberg Bay, Wilderness and beyond. Protect your home from midges, flies and wildlife while keeping views, airflow and light.

Why Standard Insect Screens Fail on the Coast
The Garden Route triple challenge of salt laden air, high humidity, and persistent coastal breeze breaks down cheap screen materials fast. Add tiny midges and curious wildlife and generic screens simply do not last.
The real costs of poor screens
- Health and comfort: midge bites, poor sleep, closed windows
- Money drain: frequent replacements outcost quality solutions
- Property risks: wildlife intrusion and damage through weak fittings
Salt Air and Corrosion: What Is Actually Happening
Microscopic salt crystals settle on frames and meshes. With moisture they form a corrosive film that pits aluminium, weakens fasteners and stains fabrics. This process continues many kilometres inland during onshore winds.
| Material | Coastal lifespan | Corrosion resistance | Use |
|---|---|---|---|
| Standard aluminium | six to eighteen months | Poor | Avoid on coast |
| Powder coated aluminium | three to five years | Good | Budget option |
| 316 stainless mesh | eight to twelve years | Excellent | Premium choice |
| Advanced synthetic mesh | seven to ten years | Excellent | High performance |
Local insight
Installs near Knysna Lagoon and open ocean exposures keep frames in great condition for years when we specify marine grade fasteners, sealed corners and proper drainage in the sash.
The Midge Problem
Standard insect mesh openings at about one point two to one point six millimetres let midges through. For the Garden Route aim for zero point four to zero point six millimetres in a quality mesh that resists sagging.
Fine mesh advantages
- Blocks midges and filters dust
- Extra privacy with daytime light
- Better protection from wind splash
Trade offs
- Slightly lower airflow which is minimal with high quality mesh
- Collects more dust and needs light rinses
The sweet spot
High tension fine mesh at zero point four to zero point six millimetres with marine hardware gives the best comfort and durability on the coast.
Materials That Actually Work Here
Frames and hardware
- Marine grade aluminium with thick powder coat
- 316 stainless for hinges, corners and high wear points
- Sealed corners and drainage paths to shed water
- UV stable seals and gaskets
Mesh options
316 stainless steel mesh for maximum life and security. Advanced synthetics for excellent corrosion resistance and flexibility. Hybrid coated meshes combine both strengths.
Avoid common mistakes
Do not buy on price alone. A low cost screen that fails in six to twelve months costs more than a marine grade screen that lasts eight to twelve years.
How to Choose for Your Home
Assess your exposure
- Distance to ocean: within two kilometres use fully marine grade. Five to ten kilometres inland still benefits
- Elevation and wind: ridges and open aspects need reinforced fixing
- Water bodies: lagoons and lakes bring more midges which calls for finer mesh
Room by room strategy
| Area | Best screen | Notes |
|---|---|---|
| Kitchens | Retractable or sliding | High airflow and easy cleaning |
| Bedrooms | Fixed fine mesh | Midge control is the priority |
| Patios and stacker doors | Sliding or retractable plus zones with security mesh | Balance view and wildlife deterrent |
Coastal Care: Make Them Last
Monthly about five minutes
- Rinse mesh and frames with fresh water
- Clear drainage and weep paths
- Quick check on corners and fasteners
Quarterly about thirty minutes
- Mild soapy wash with a soft brush
- Rinse and air dry fully
- Lubricate moving parts if retractable
Local Tips by Area
Knysna and lagoon areas
High humidity and midges. Prioritise fine mesh, sealed corners and marine fasteners.
Plettenberg Bay
Open ocean exposure. Use maximum corrosion protection with view friendly options.
Wilderness and Sedgefield
Lakes and rivers. Focus on midge control and regular fresh water rinses after wind events.
George and inland areas
Lower salt with mixed insects. Choose balanced mesh with robust frames.
Frequently Asked Questions
Will fine mesh block my view or light
Quality fine mesh preserves brightness and keeps views usable while blocking midges.
Can I clean or replace the mesh
Yes. Modular panels lift out for easy rinsing and professional re meshing.
Do they fit wooden frames
Yes. Screens are custom made for timber, aluminium and uPVC profiles.
Do you cover the whole Garden Route
Yes. Knysna, Plettenberg Bay, Wilderness, George, Mossel Bay and surrounds.
