Slat Size and Light Control

Different slat sizes impact the amount of light entering a room. Standard slats allow filtered light to gently illuminate the space, while wider slats excel in providing better light-blocking capabilities. Knowing your desired level of brightness and ambience is crucial when selecting slat sizes for prime light control.

Slat Size and Privacy

The connection between slat sizes and privacy is essential. Wider slats, when closed, minimise gaps, offering increased privacy. Consider your privacy needs in different rooms to choose slat sizes that provide the desired level of seclusion.

Benefits of Wide Slat Sizes - 50mm

Wider slat sizes, such as the 50mm variant, present a different set of advantages. Their broader surface area not only contributes to a bold design statement but also grants greater control over incoming light. Choosing wider slats can be a deliberate move toward creating a more impactful aesthetic while enjoying enhanced light control.

Visual impact is inherent in slat sizes, affecting the overall aesthetic of your interior décor. Harmonising these sizes with the room's dimensions, furnishings, and design theme is essential. Opt for slat sizes that complement the existing elements to create a seamless and appealing space.

Maintenance and Cleaning

Maintaining wooden Venetian blinds involves customised care based on slat size. Smaller slats might demand more intricate cleaning due to their size, whereas wider slats can be easier to maintain. Regular cleaning routines ensure the longevity and functionality of the blinds.
