If you're choosing between timber and PVC venetian blinds, the short answer is this: timber gives you a warmer, more natural look and works best in dry, low-moisture rooms, while PVC resists moisture and fading and is the safer choice for bathrooms, kitchens and north-facing windows that get direct sun. At CAS Blinds both ranges are priced the same, so this isn't really a budget decision — it comes down to where the blind is going and how much upkeep you want to do.

Here's everything you need to know before you order.

Structure and Material: What You're Actually Buying

Both blind types use the same horizontal slat mechanism, tilting to control light and privacy, and both are available in our standard 50mm slat width, which is the most popular size for Sydney homes because it lets in more light per slat than the older 25mm profile while still giving a clean, contemporary look.

Timber venetian blinds are milled from basswood or a similar lightweight hardwood, then finished with a stain or paint coating. The grain and weight are real — you're getting an actual timber product, not a printed finish. This is what gives timber blinds their depth of colour and the slightly warmer feel against natural light.

PVC venetian blinds are extruded plastic slats, usually with a wood-grain embossed finish or a smooth painted finish. Modern PVC has come a long way from the flat, glossy plastic look of older blinds — the better wood-grain finishes are genuinely difficult to tell apart from timber at a glance, especially once they're hung and tilted.

The practical difference shows up in three places: how they handle moisture, how much they weigh, and how they age over time.

Price Comparison

At CAS Blinds, both ranges start from the same price — $89 for a 50mm slat blind — so unlike many suppliers who charge a premium for real timber, this isn't a budget decision. Landlords fitting out multiple rental properties, or anyone doing a whole-house job in wet-prone rooms, will still lean PVC for durability rather than cost.

Moisture and Fade Resistance

This is the single biggest factor in choosing between the two.

Timber absorbs moisture. In a bathroom, laundry, or any window that gets direct steam or splashback, timber slats can warp, swell, or develop mould over time — even with a protective coating. Manufacturers generally don't recommend timber venetians in wet areas for this reason.

PVC is fully moisture-resistant. It won't warp, swell, or grow mould, which makes it the standard choice for bathrooms, kitchens near sinks, and laundries — see our full breakdown of moisture-resistant PVC blinds for bathrooms and kitchens. It also handles Sydney's humidity swings — particularly through summer — without any risk of the slats sticking or the mechanism seizing.

If you're set on the timber look but your home runs humid, read our notes on timber venetian blinds in high-humidity areas before you order.

On fading, the pattern reverses slightly. Good quality timber holds its colour reasonably well if it's not in constant direct sun, but PVC with a UV-stabilised finish tends to outperform timber on windows that get harsh afternoon light for years on end, since the colour is baked into the material rather than sitting as a surface stain.

Rule of thumb: if the window is in a bathroom, kitchen, laundry, or gets strong direct sun for most of the day, go PVC. If it's a living room, bedroom, or study with moderate light, timber is the better-looking option and moisture isn't a concern.

Maintenance and Cleaning

Both are low-maintenance compared to fabric window coverings, but they're not identical.

• PVC: wipe down with a damp cloth, no special product needed. It won't stain and doesn't need refinishing. This is as close to "set and forget" as blinds get.
• Timber: dust regularly with a dry or slightly damp cloth — avoid soaking the slats, since standing moisture is what causes warping over time. Depending on the finish, timber may benefit from an occasional wood-safe polish to keep the coating looking fresh.

For households with kids or pets, PVC's wipe-clean surface is generally the more forgiving option day-to-day.

Insulation and Acoustic Performance

Timber has a natural edge here. Being a denser, heavier material, timber slats provide marginally better thermal insulation and sound dampening than PVC — noticeable mostly in larger windows or rooms where you're trying to reduce heat transfer or street noise. The difference isn't dramatic, but if insulation is a priority alongside light control, timber is the stronger pick.

PVC is lighter, which has its own advantage: less strain on the tilt and lift mechanism over the life of the blind, particularly on wider windows where a full timber set can be noticeably heavier to operate.

Which One Suits Your Sydney Home?

Sydney's climate — humid summers, strong UV, and plenty of coastal and harbourside homes with high moisture exposure — makes the choice fairly practical rather than purely aesthetic:

• Bathrooms, kitchens, laundries → PVC, every time. Moisture resistance isn't optional in these rooms.
• North and west-facing rooms with strong direct sun → PVC for fade resistance, unless you're prepared for some natural colour change on timber over the years.
• Living rooms, bedrooms, studies, home offices → Timber, for the warmer finish and slightly better insulation — moisture isn't a factor here.
• Rental properties or investment homes → PVC, for durability across multiple units — no premium over timber at CAS Blinds, so it's the lower-risk pick for tenanted properties.
• Coastal or harbourside homes with high humidity year-round → PVC, to avoid warping regardless of which room it's in.

A Note on Child Safety

Both timber and PVC venetian blinds are corded products by default, which means they fall under Australia's mandatory corded blind safety standards. If you have young children or grandchildren visiting, it's worth understanding the requirements around cord length, cleat height and looped cord risk before you order — see our guide on keeping kids safe with the right blinds and our overview of cordless window treatments for child safety. Cordless and motorised options remove this risk entirely and are available on both timber and PVC ranges.

FAQs

Is PVC venetian blind cheaper than timber? Not at CAS Blinds — our timber and PVC 50mm venetians are both priced from $89, so the choice comes down to where the blind is going and how it will be used, not budget.

Can I use timber venetian blinds in a bathroom? It's not recommended. Timber absorbs moisture and can warp or develop mould in high-humidity rooms over time, even with a protective finish. PVC is the standard choice for bathrooms and other wet areas.

Do PVC venetian blinds look cheap? Modern PVC blinds with a wood-grain embossed finish are difficult to distinguish from real timber once installed, particularly in the 50mm profile. Flat, glossy PVC finishes are the ones that tend to look less premium — ask to see a sample of the specific finish before ordering.

Which lasts longer, timber or PVC? Well-maintained PVC generally lasts as long as or longer than timber, since it doesn't warp, fade as readily, or require the same care around moisture. Timber can last just as long in the right room (dry, moderate light) but is more vulnerable to environmental wear.

Are timber and PVC venetian blinds both available in 50mm slats? Yes, both ranges are available in the popular 50mm slat width, which is our most requested size for Sydney homes.

Can I mix timber and PVC blinds in the same house? Absolutely — many customers use PVC in bathrooms and kitchens and timber in living areas and bedrooms within the same home. It's a common and practical combination.

Do both options come with a free measure and quote? Yes. Our free in-home measure and quote service covers all product ranges, including both timber and PVC venetians, across Greater Sydney.

Are venetian blinds safe for kids? Corded venetian blinds — timber or PVC — must meet Australia's mandatory child safety standards around cord length and cleat placement. Cordless and motorised versions remove the cord risk entirely. See keeping kids safe with the right blinds for the specific requirements.
