TL;DR: Aluminium venetian blinds suit kitchens, service yards and sun-baked windows because they shrug off moisture and stack slim.
PVC venetian blinds give a thicker, wood-look slat for bedrooms and living rooms, and both are safest with cordless or tensioned controls when young children live at home.
Choosing venetian blinds for an HDB flat usually comes down to two materials, aluminium and PVC, and the right answer depends far more on where the window sits than on the colour chart. A kitchen window above the sink, a bedroom that takes the afternoon sun and a living room facing the common corridor each ask something different of a blind. As a Singapore supplier of venetian blinds, roller blinds and zip blinds, we would rather you pick the right material once than replace a blind that was wrong for its room. Here is how the two compare on slat size, humidity and cord controls.

Which Is Better for an HDB Flat, Aluminium or PVC Venetian Blinds?
Aluminium is the better choice for wet, hot or tight spots, while PVC suits dry living spaces where you want a chunkier, warmer look. In practice, the HDB venetian blinds Singapore families order most often are aluminium for the kitchen and toilet, and PVC or timber-look for the bedrooms. Aluminium slats are thin, light and do not absorb water, so they handle steam from cooking and the splash zone around a sink without swelling. PVC slats are thicker and read like painted wood from across the room, which is why homeowners who love the timber look but worry about humidity often land on them.
| Feature | Aluminium venetian blinds | PVC venetian blinds |
|---|---|---|
| Typical slat width | Around 25mm (1 inch) on our standard aluminium range; mini and micro slats are narrower | Wider, wood-look slats, commonly around 50mm |
| Look | Slim, clean, modern | Chunky, painted-timber feel |
| Moisture | Does not absorb water | Resists moisture |
| Weight | Light, easy to lift | Heavier on wide windows |
| Stack when raised | Compact | Deeper, blocks more of the top glass |
| Best rooms | Kitchen, toilet, service yard, study | Bedroom, living room |
| Watch-outs | Slats can dent if knocked | Long slats can sag under strong heat over time |
Does Slat Size Matter in a Small HDB Window?
Yes, because slat width decides how much depth the blind needs, how big it stacks and how much view you keep. Narrow aluminium slats tilt within a shallow recess and fold into a small bundle at the top, which keeps more glass clear on the compact windows common in older flats. Wider PVC slats give fewer lines across the view when open, but each slat swings further when it tilts, so it can catch on a protruding casement handle or a window grille. Before we quote, we check the recess depth, the handle position and whether the blind will sit inside or outside the frame. Getting HDB venetian blinds Singapore installers can fit cleanly starts with that measurement, not with the brochure.
How Do Aluminium and PVC Venetian Blinds Handle Singapore Humidity?
Both cope with humidity far better than real timber, which is the main reason they dominate Singapore kitchens and bathrooms. The Meteorological Service Singapore puts the mean annual relative humidity at around 82%, and it frequently reaches 100% during prolonged rain. Aluminium venetian blinds simply do not absorb that moisture, so a quick wipe with a damp cloth keeps them looking new. PVC venetian blinds are equally happy in steam, though very long slats facing the afternoon sun through glass can soften and bow over the years, so we suggest narrower panels or aluminium for large west-facing windows. During the Northeast Monsoon from December to early March, close windows before a storm, because wind-driven rain makes any blind clatter and can bend slats.
What Are Mono Cord Venetian Blinds, and Are They Safe for Kids?
Mono cord venetian blinds use a single cord to both raise the blind and tilt the slats, so you twist to angle the light and pull to lift. That means one tidy cord at the side instead of a pull cord plus a tilt wand, which looks neater and is easier for elderly parents to use. It is still a cord, though, and that matters in a home with toddlers. The US Consumer Product Safety Commission recorded more than 200 strangulation incidents involving window covering cords among children up to eight years old from 2009 to 2021, and a child died in 48% of them.
“Young children can quickly and silently become strangled on pull cords, continuous loop cords, inner cords or any other accessible cords on window coverings. Cordless window blinds, shades, draperies and other window coverings are the safest option.” – Alex Hoehn-Saric, Chair, US Consumer Product Safety Commission
Which control should you choose?
For a nursery or a child’s room, go cordless or motorised. If you prefer mono cord venetian blinds elsewhere, fit a cord tensioner or cleat high on the wall so the cord never hangs loose. Our child-safe blinds guide covers the safeguards in more detail.
Venetian Blinds Pros and Cons: What Should You Know Before Ordering?
Weighing venetian blinds pros and cons honestly saves you from disappointment later. On the plus side, tilting slats give finer light control than almost any other blind, letting you block a low sun while keeping the room bright. They are slim, they suit every room in the flat in one material or another, and hard slats wipe clean without dismantling anything. On the minus side, slats collect dust and need a regular wipe in a busy kitchen, and even fully closed they never give total darkness, so a bedroom that must be pitch black needs a blackout blind or curtain layered behind. Aluminium can dent if a child swings on it, and PVC is heavier to lift on a wide window.

Frequently Asked Questions
Are aluminium venetian blinds good for HDB kitchens?
Yes. Aluminium does not absorb moisture or cooking steam, wipes clean quickly and stacks small above a sink window.
Are PVC venetian blinds waterproof?
They resist moisture well and suit bathrooms, but avoid long slats in strong direct afternoon heat, which can make them bow over time.
Do venetian blinds block out light completely?
No. Light passes between slats and around the edges even when closed. Pair them with a blackout layer if you need a dark bedroom.
Are mono cord venetian blinds child-safe?
Not on their own. Add a cord tensioner or cleat, or choose cordless or motorised control for children’s rooms.
Which slat size suits a small HDB window?
Narrower aluminium slats usually work best, as they need less depth to tilt and take up less glass when raised.
