Fly Screens & Security Screens Knysna
Aluminium-framed insect screens, retractable fly screens, and Corner Star security screens for Knysna homes. Between the lagoon and the forest, Knysna has one of the most demanding screen environments on the Garden Route. Duncan is based here.
What fly screen and security screen options are available for Knysna homes?
- Custom Blinds supplies and installs aluminium-framed fly screens, retractable insect screens, fixed security screens, and Corner Star security barriers for Knysna properties. Duncan is based in Knysna.
- Knysna’s lagoon microclimate produces high mosquito and midge activity from October through April, concentrated around waterfront properties on Thesen Island, Leisure Isle, and the lagoon foreshore. Fine-mesh screening is the standard specification for these locations.
- Security screens use reinforced stainless steel or aluminium mesh rated for baboon resistance. Properties bordering the Knysna forest, Brenton-on-Sea, Belvidere, and elevated positions above the lagoon face baboon intrusion that standard fly screens cannot stop.
- Duncan assesses each Knysna property for its specific threat profile. Many homes need both: fine insect mesh on interior windows and security screens on openings accessible from the forest fringe.
- All frames are powder-coated aluminium rated for coastal corrosion. Corner Star is the security screen partner. Garden Route only.

“Knysna sits between forest and water, and both create real problems for homeowners. The lagoon brings mosquitoes every summer. The forest brings baboons year-round on properties near the Heads, Brenton, and Belvidere. One screen does not fit all openings. You need the right specification for each one.”

What fly screen options are available for Knysna’s lagoon-side properties?
Aluminium-framed fly screens fit windows, sliding doors, stacking doors, and hinged openings across Knysna’s range of property configurations. Fixed screens mount permanently for year-round insect protection. Retractable screens pull across when needed and disappear into a slim cassette housing when not, preserving lagoon and forest views.
Mesh grades range from standard fibreglass insect mesh to stainless steel micro-mesh that blocks the smallest midges common around the Knysna Lagoon at dusk. Mosquito activity peaks from October through April, concentrated around Thesen Island, Leisure Isle, and the lagoon foreshore. All frames are powder-coated aluminium rated for the salt air and humidity of Knysna’s coastal environment. Custom sizing fits the non-standard openings common in older Knysna properties.
Which Knysna properties need baboon-rated security screens?
Security screens use heavy-gauge stainless steel or aluminium mesh in reinforced frames engineered to resist forced entry and sustained baboon force. The Corner Star system uses a patented clamp mechanism that secures the screen without visible fixings, providing rated barrier performance while maintaining the clean lines that suit Knysna’s architectural styles from Thesen Island contemporary to traditional forest-edge homes.
Standard insect mesh fails within minutes under baboon attention. Security-grade mesh in reinforced frames withstands sustained attempts. Knysna properties most at risk include those in the forest fringe areas of Brenton-on-Sea, Belvidere, and upper Leisure Isle, homes near the Heads where baboon troops move through regularly, and any property with accessible ground-floor or first-floor openings facing dense vegetation. Duncan identifies which openings need security-grade mesh versus standard insect screening during the site assessment.
How does Duncan assess a Knysna property for screens?
Duncan is based in Knysna and assesses properties across Thesen Island, Leisure Isle, Brenton-on-Sea, Belvidere, the Heads, Phantom Pass, and all surrounding areas. Being based locally means same-week site visits in most cases. The assessment identifies insect pressure at each opening, checks mounting surfaces and window operation types, and determines which openings face baboon or monkey corridors.
Each screen is then custom manufactured to the exact opening dimensions, powder-coated to match existing joinery, and installed by the same team. Typical turnaround from site visit to installation is 2 to 3 weeks.
Screen questions answered for Knysna homeowners
Do you install screens across Knysna?
Yes. Duncan is based in Knysna and assesses properties across Thesen Island, Leisure Isle, Brenton-on-Sea, Belvidere, the Heads, and all surrounding areas. Same-week site visits are available in most cases. Every screen is custom measured and installed by the same team.
Are your screens baboon-proof?
Security-grade screens are rated for baboon resistance. Standard fly screens are not. Duncan assesses which openings at your property face baboon risk and specifies security-grade mesh and reinforced frames for those openings. Properties near the forest fringe, Brenton, Belvidere, and the Heads typically need security screens on ground-floor and accessible first-floor openings.
Will screens rust in Knysna’s salt air?
All frames are powder-coated aluminium specified for coastal environments. Mesh options include marine-grade stainless steel for the highest corrosion resistance. Standard steel mesh is not recommended for Knysna properties within the salt zone, particularly waterfront homes on the lagoon.
Can screens fit Knysna’s older properties with non-standard openings?
Yes. All screens are custom manufactured to the exact dimensions of each opening. Non-standard sizes, unusual frame profiles, and heritage window configurations are all accommodated. Duncan takes precision measurements on site before any screen is manufactured.
