Interior design trends change like a kaleidoscope, but some solutions stay with us for longer. One of these is wall slats – stylish, functional and incredibly versatile. These vertical or horizontal decorative elements give an ordinary space character and depth. It’s no wonder that wall slats are now found in living rooms, bedrooms, kitchens and offices, and their popularity extends beyond interiors – exterior slats also look just as striking on façades.

In this post, we’ll show you step by step how to transform your interior easily, where slats work best, and what the differences are between interior slats and exterior. 


Why are wall slats so fashionable?

Minimalism, elegance and cosiness – these are the qualities that have made wall slats a favourite with designers and homeowners. They suit interiors decorated in Scandinavian, loft and classic styles alike.

Wall slats:

  • break up the monotony of smooth surfaces,

  • add rhythm and depth to a space,

  • have acoustic properties – they can help soundproof a room,

  • are easy to install and available in a wide range of colours.

Types of slats – which should you choose for your project?

Interior slats are used as decoration in homes, offices and restaurants. They can be fitted across an entire wall, as a panel behind the television or as a partition to divide a space. They are most commonly made from MDF, veneer or composite materials.

Exterior slats are fitted to building façades, terraces and balconies. They serve not only an aesthetic purpose but a practical one too – protecting against the sun and increasing privacy. They are made from weather-resistant materials such as aluminium, steel or composite.

  • SLATS AND SMALL SLATS

In everyday speech, people often say small slats instead of slats. These are simply smaller, narrower elements that can be fitted in various arrangements – vertically, horizontally or even diagonally.

Wall slats step by step – how do you install them?

Preparing the wall

Before you start installing the slats, make sure the surface is flat and clean. Any imperfections should be filled and smoothed out.

Planning the layout

Decide whether the slats should cover the entire wall or just part of it – for example, behind the television or in a home office corner. It’s a good idea to make a simple sketch and mark out the distances between the slats.

Installing wall slats

  • Step 1: Mark the installation lines on the wall.

  • Step 2: Cut the slats to the required length.

  • Step 3: Fix them in place using mounting adhesive or special battens.

  • Step 4: Keep the gaps even – spacers are best.

  • Step 5: Finish off around the floor and ceiling.

Installing external slats

For external slats, installation is most often carried out on a special aluminium frame. This makes the elements stable and resistant to wind and rain.


 

Ideas for wall slats.

  • IN THE LIVING ROOM

Wall slats work brilliantly behind the television, in the relaxation area or as a feature on one wall. They create an elegant backdrop for furniture and accessories.

  • IN THE BEDROOM

Placed behind the bed, they replace the headboard and give the bedroom a luxurious feel.

  • IN THE KITCHEN AND DINING ROOM

Slats in the dining room can visually define the dining area, while in the kitchen they add warmth to modern designs.

Interior slats help define work areas while keeping the space open.

Benefits of using slats
