Why Choose 89mm Louvres?

The key appeal of the 89mm louvre is its ability to open up a space visually. The wider slats create larger gaps between each louvre when open, allowing more natural light into the room and offering clearer views outside.

Benefits of 89mm louvres include:

• Increased light flow into the room
• Better visibility when louvres are open
• A bold, contemporary appearance
• Ideal proportions for tall windows and doors

If you have a feature window or a view you want to make the most of, the 89mm louvre can be a great option.

Ideal for Tall Windows and Doors

89mm louvre slats work particularly well on:

• Full-height shutters
• French doors and patio doors
• Tall windows with generous drops

On these larger openings, the wider slats look balanced and intentional, enhancing the overall scale of the shutter rather than overpowering it.

Things to Consider with 89mm Louvres

Because of their size, 89mm louvres require a slightly wider shutter frame to allow the slats to rotate correctly. In most situations this isn’t an issue, but it is something worth considering for certain window styles.

In particular, on bay windows, the deeper frame required for 89mm louvres can sometimes:

• Project further into the room
• Appear visually heavy
• Distort the proportions of the bay

For this reason, many homeowners choose a 63mm or 76mm louvre for bay windows, as these slimmer slats tend to sit more neatly within the angles of the bay.

89mm Louvres Compared to Smaller Slat Sizes

While smaller slats such as 63mm and 76mm offer a more subtle and compact look, 89mm louvres are designed to make a statement.

They are best chosen when:

• Window height allows the slats to look well-proportioned
• Maximising light and view is a priority
• A more contemporary or architectural style is desired

For smaller windows or bays, narrower louvres are often a more practical and visually balanced option.
