Singapore has a mosquito problem. Year-round heat and humidity make it one of the most active dengue environments in Southeast Asia, and the June to October peak season pushes the risk higher. The standard response — closing your windows — trades one problem for another. Shut everything up and your flat turns stuffy within the hour.
An insect screen solves this. But the market is full of options at wildly different price points, and most homeowners buy the wrong one because nobody explains the differences clearly.
This guide covers everything: the types of insect screens available in Singapore, what each is suited for, what to look for before buying, and how to get one installed in your HDB flat without drilling a single hole.
What Is an Insect Screen?
An insect screen is a mesh barrier fitted over a window or door opening. It lets air pass through while blocking insects. That’s the whole job.
The key variables are the mesh material, the frame system that holds it, and how the screen is attached to your window. Getting those three things right determines whether your screen lasts two years or ten.
Types of Insect Screens Available in Singapore
Fixed Insect Screens
A fixed screen is permanently attached to the window frame. It does not move. Air passes through when the window is open, and insects cannot get in.
Fixed screens are the cheapest option. They are also the most visible. The mesh is always there — you see it whether the window is open or closed. In HDB flats where aesthetics matter and living spaces are compact, many homeowners find fixed screens visually intrusive over time.
Fixed screens also collect dust and are harder to clean because they cannot be removed easily.
Sliding Insect Screens
A sliding screen moves along a track, similar to a sliding door. You slide it across when the window is open and push it back when closed.
Sliding screens are common on balcony doors and large window openings. They require a track system installed along the top and bottom of the frame, which may not suit all window types. Unlike fixed screens, you can slide them out of the way, which helps with cleaning and aesthetics.
Magnetic Insect Screens
Magnetic screens use a magnetic frame to attach to the window without any tools or adhesive. They can be removed entirely in seconds. The magnets hold the screen in place during normal use, and the centre split allows easy passage if needed.
Magnetic screens work well for homeowners who want a removable solution and do not need the screen to be permanently fitted. The downside is that they are not custom-fitted — they come in standard sizes and may not seal perfectly against irregular window frames. Gaps at the edges let insects in.
Retractable Insect Screens
A retractable screen rolls into a slim housing unit mounted to the window frame. When you need it, you pull it across the opening. When you do not, it retracts and the window looks completely clear.
Retractable screens are the most practical option for Singapore HDB flats. There is no permanent visual obstruction. The housing unit sits flush against the frame. The screen deploys and retracts in one smooth motion.
DinoMesh’s retractable system is custom-fitted to your exact window dimensions — not an off-the-shelf size that leaves gaps. The mesh retracts into its housing without creasing or bunching, and the aluminium alloy frame holds its shape over years of daily use.
Insect Screen Mesh Materials: What’s the Difference?
The frame system matters, but the mesh material determines durability, visibility, and whether your screen survives contact with a cat.
Fiberglass Mesh
The cheapest option. Lightweight and easy to work with, which is why it is common in low-cost imported screens. The problem: fiberglass frays at the edges, stretches over time, and degrades under Singapore’s UV exposure. Most fiberglass screens need replacing within 18 months to 2 years. Not suitable for a quality retractable system.
Nano-Coated Polyester Mesh
Significantly more durable than fiberglass. DinoMesh’s polyester mesh is nano-coated — a protective treatment that makes it scratch-resistant and deformation-resistant. It holds its shape in a retractable system and does not fray or stretch with daily use.
Over 93% of airflow passes through the mesh when deployed, so your flat stays ventilated. And the weave is fine enough to keep out mosquitoes, flying termites, and the insects that peak during dengue season.
Best for: most HDB homeowners who want a durable, well-priced solution.
304 Stainless Steel Mesh
The strongest option available. The woven steel structure cannot be deformed by pet claws, does not rust in Singapore’s humidity, and maintains excellent outward visibility — the mesh becomes almost invisible from inside the flat.
The cost is higher than polyester. But for cat owners in particular, stainless steel is not a luxury — it is the only material that holds up reliably against cats that claw or push against the screen.
Best for: cat and pet owners, anyone who wants maximum longevity.
Why Singapore Homes Specifically Need Insect Screens
The Dengue Risk
Singapore’s National Environment Agency (NEA) tracks dengue cases year-round. The June to October period is peak season, but cases occur throughout the year. Aedes mosquitoes — the species that transmits dengue — are active during daylight hours, which is exactly when most people have their windows open.
An insect screen is one of the most direct barriers you can put between your home and the mosquitoes outside. Unlike repellents or sprays, it works passively, all day, without any ongoing effort.
HDB Flat Design
Most HDB flats in Singapore are designed for cross-ventilation. Windows on opposite sides of the flat allow airflow to move through naturally. This works well — but it also means that if any window is unprotected, mosquitoes and insects have a clear path in.
Open-corridor HDB blocks, in particular, have significant insect exposure on the corridor-facing windows. Ground floor and lower floor units face more insect activity from surrounding greenery and drains.
Singapore’s Humidity
A fixed or magnetic screen that does not seal tightly degrades faster in Singapore’s climate than in drier environments. Mesh materials that are not treated for humidity resistance will rust, fray, or lose structural integrity faster. This is one reason DinoMesh uses nano-coated polyester and rust-resistant 304 stainless steel rather than untreated materials.
What to Look for When Buying an Insect Screen in Singapore
Custom Fit vs Standard Sizes
Standard-size screens leave gaps. HDB windows are not uniform — frame depths, opening widths, and sill dimensions vary between blocks, flat types, and even between different windows in the same flat. A screen that does not fit precisely is a screen with gaps, and gaps let insects in.
A custom-fitted screen is measured on-site and built to the exact dimensions of each window. DinoMesh measures every window before fabrication — no guesswork, no gaps.
No-Drill Installation
HDB renovation rules restrict certain types of structural work, and many renters cannot make permanent modifications to their unit. Look for a screen system that installs without drilling.
DinoMesh’s installation uses tape and silicone adhesive only — zero holes in the wall, fully reversible, and suitable for both HDB owners and renters. The installation process is handled end-to-end by DinoMesh, including measurement, fabrication, and fitting.
Warranty
A one-year warranty on workmanship and product quality is standard for a quality installation. It covers defects in the mesh, frame, and retraction mechanism. DinoMesh includes this on every installation — if something fails within the first year, it is fixed at no cost.
Frame Colour Options
The frame should match your existing window frame as closely as possible. DinoMesh offers 10 powder-coated aluminium frame colours: Galaxy Black, Matte Black, Dark Gray, Light Silver, Gray, Turquoise, Coffee/Brown, Champagne, Metallic Gray, and White. Most HDB window frames in Singapore fall within this range.

Insect Screens for Specific Home Situations
HDB Renters
Renters cannot drill into walls or window frames without risking their deposit. DinoMesh’s tape-and-silicone installation leaves no permanent marks, making it one of the few screen systems renters can safely install. The system can be removed cleanly when moving out.
Cat Owners
Cats claw, lean against, and push through mesh screens. Polyester mesh holds up to light contact but will eventually deform under sustained pet pressure. The only reliable option for cat owners is 304 stainless steel mesh. DinoMesh’s stainless steel option is specifically recommended for households with cats or dogs.
Parents with Young Children
Children in higher-floor HDB flats create window safety concerns beyond insects. DinoMesh’s retractable system includes a durable aluminium alloy frame that stays firmly in place when deployed. The mesh itself is deformation-resistant and does not buckle under accidental pressure. For added peace of mind, the retractable design means the screen can be locked in the deployed position.
Ground Floor and Low-Floor Units
Ground floor and lower-floor units near greenery, drains, or corridors face higher insect exposure. A 20×20 mesh (smaller openings than the standard 18×16) provides a finer barrier against sandflies and midges in addition to mosquitoes — worth asking DinoMesh about if your unit is on a lower floor near vegetation.

Frequently Asked Questions
What is the best insect screen for HDB flats in Singapore?
A custom-fitted retractable insect screen with nano-coated polyester mesh is the best choice for most HDB homeowners. It blocks mosquitoes and insects, retains over 93% airflow, installs without drilling, and is durable enough for daily use over several years. If you have cats, choose the 304 stainless steel mesh option instead. DinoMesh offers both in a retractable system custom-fitted to your windows.
Do I need permission from HDB to install an insect screen?
DinoMesh’s installation uses tape and silicone only — no drilling, no structural modification. This type of installation does not require HDB approval. Always check with HDB directly if you are unsure about specific renovation requirements for your block.
How much does an insect screen cost in Singapore?
Prices vary depending on window size, mesh material, and the number of windows. Polyester mesh is more affordable; stainless steel costs more due to the material. DinoMesh provides an exact quote after measuring your windows — there are no hidden costs and no commitment required at the consultation stage. WhatsApp +65 9752 9911 to arrange a free visit.
How long does an insect screen last in Singapore?
A nano-coated polyester mesh in a retractable system typically lasts 3 to 5 years with normal use. 304 stainless steel mesh lasts significantly longer. Fiberglass mesh — the cheapest option on the market — usually needs replacing within 18 months to 2 years due to UV degradation and fraying. Proper cleaning (damp cloth or soft vacuum brush, no harsh chemicals) extends the lifespan of any mesh.
Can I install an insect screen if I am renting my HDB flat?
Yes. DinoMesh’s installation requires no drilling and leaves no permanent marks. The system can be removed cleanly when you move out. This makes it suitable for renters as well as owners.
Will the insect screen block my view or reduce airflow?
No. DinoMesh’s mesh systems retain over 93% natural airflow when deployed. The mesh is also engineered for maximum transparency — from inside the flat, it is nearly invisible and does not obstruct the view meaningfully.
How do I maintain an insect screen?
Wipe down the mesh with a damp cloth or vacuum gently with a soft brush attachment. Do not use harsh chemicals or high-pressure water. Monthly light cleaning is sufficient for most homes. The aluminium alloy frame requires no maintenance beyond an occasional wipe.
What is the lead time for DinoMesh installation?
3 to 4 weeks from the order confirmation date. Each screen is custom-fabricated to your window dimensions, which is why it is not an off-the-shelf product. A 50% deposit is required to confirm the order and begin fabrication.
Does DinoMesh install in condominiums and landed homes as well?
Yes. DinoMesh installs in HDB flats, condominiums, and landed properties across Singapore. The consultation, measurement, and installation process is the same regardless of property type.
