woodlock from Kahrs

Woodloc® the strongest joint

Kährs are the original developers of the breakthrough Woodloc® method of joining boards. Woodloc® ensures very tight timber joins which are almost seamless and protect the wood from warping and the joints from separating or gapping.

Wood expands contracts and reacts to moisture, which directly affects joints. The Woodloc® joint process is far superior to other joining methods, preventing gapping and damage to floor integrity.

Kährs Woodloc® has a unique record of timber flooring installation worldwide, with 25,000,000 m2 of Woodloc® flooring installed since introduction. 


laying a woodloc wooden floor

The easiest installation

The innovative Woodloc® joining method also makes installation much simpler and quicker. The strong joins and high tensile stress integrity of Woodloc® flooring allow timber floors to be accurately custom-fitted and laid onsite in any configuration. 


underfloor heating with wooden floor

Kährs and underfloor heating

Kährs 15mm multi-layer parquet floors or 7 mm Linnea floors can be safely laid over underfloor heating.

Technical issues to be considered with underfloor heating -

1.      The surface temperature of the floor must not exceed 27 Celsius. This thermal profile requirement also relates to floors installed with heating equipment and fittings, like radiator pipes and floor areas exposed to direct heating.

2.  Beech and hard maple naturally expand and contract more than other timbers. It is recommended to consult with your timber flooring specialists regarding any possible issues related to your heating system. 


wooden floor climate stability

The best climate stability

Wood, being a natural material, responds to climate conditions seasonally. The expansion and contraction of timber can cause the movement of boards. Kährs timber floors are designed to deliver the perfect balance to minimise floor movement.


the strength of wooden floors

The strongest surface and the best finish

The surface of a floor is subjected to considerable wear and tear. Kährs timber flooring is designed to maintain an excellent finished surface in combination with very high durability and long product life. A super-strong lacquer is used to maintain surface appearance and resist wear. 


wooden floors that retain colour

Your Kährs Floor Won't Turn Yellow or Discolour

Kährs' high tech UV-cured acrylic finish is designed to be highly resistant to common household stains for up to 24 hours and will not yellow or fade over time.


traditional solid wood cut

Traditional solid wood cut

The Kähr's method of woodcutting, known as plain sawn, is the same technique used for our wood floors. The result is a much finer, more traditional wood grain that completely eliminates the splitting associated with peeled veneers.


Kahrs wooden floor constuction

Kährs - The same as a solid

Kährs timbers incorporate a plain-sawn wear layer which can withstand the stresses and strains of daily use for decades. This wear layer is super-tough and is made to protect floor surfaces. It also makes cleaning easy and ensures that your timber floor is always looking great.

Wood Floor Designs


Create the look you really want

Wood Floor Designs


Create the look you really want

truly unique wooden flooring can be yours

Every floor has its own unique pattern. Wood flooring from Kährs is a superb natural product. We are working with something that nature has created – and nature is wonderfully diverse. The appearance of any wood floor depends on a number of factors such as the wood species, the grain, the knots etc. There is a variety of different colours and structures that every tree presents, allowing us to produce wood floors of different appearance depending on how we cut the wood.

The below designs and patterns are available within the Kährs wood flooring range:

 
Strip wooden floor

1-strip - gives an intense wood feel

The surface layer of every 1-strip board is sawn from a single piece of wood. The natural appearance of the wood, with knots and variations in the colour and grain, is truly reflected in 1-strip flooring. However, for some of our 1-strip floors, we have especially selected wood to achieve little variation in colour and a minimum of knots, so that you can find a floor which suits your style.
Kährs 1-strip flooring is available in several different lengths and widths. 1-strip floors usually suit perfectly in larger rooms.


two strip  wooden floor

2-strip – floors with different characters

The surface layer is two strips' wide. The strips are selected and arranged to give each 2-strip floor a unique and individual character.

Kährs 2-strip flooring is available in two versions: one with longer strips, and one with shorter. The version with longer strips is ideal for larger rooms, while the version with shorter strips is perfect for smaller areas.


three strip  wooden floor

3-strip – a range of interior design options

3-strip flooring has a surface layer where three strips of different lengths are placed widthwise and randomly. 3-strip flooring offers you a wide range of interior design options. At Kährs, we sort some of our 3-strip flooring in a way that enhances its lively expression, but we also have 3-strip floors which we sort to create a calmer and more harmonious feel.


Ship decking  wooden floor

SHIPS DECKING - Create a maritime feel 

A Kährs shipsdecking floor gives your room a maritime feel reminiscent of boats and the sea. Our shipsdecking floors have a characteristic decorative strip of another wood species than the major wood species used for the rest of the boards, and there are wood plugs at the ends of each board in order to render the floor a real shipsdeck look.

Our shipsdecking pattern is made at our factory along with other Kährs flooring, and just like other flooring it is delivered in whole boards.


Dutch Pattern  wooden floor

Dutch pattern – a classic board in a new way

Kährs Dutch pattern flooring is a classic floor that benefits from a modern construction. The surface layer features a repeating box pattern made up of three vertical strips, laid side by side, divided by one horizontal strip across the top. When the boards have been installed, they create a stunning “cable stitch pattern” with rhythm and symmetry

Laying a Kährs Floor


It really couldn't be easier

Laying a Kährs Floor


It really couldn't be easier

Laying Kährs and Linnea with Woodloc®

The Woodloc® laying system replaces the traditional method of joining boards by gluing the tongue and groove together. With the Woodloc® joint, the parquet boards are locked together with almost invisible joins.

The rows of boards align themselves automatically, so you avoid any gaps when laying. You don't use glue. Instead, Woodloc® joins together quickly, easily and firmly, giving perfect results that withstand tough use and last throughout the life of the floor.

Because Woodloc® floors are laid without glue, the boards can also be easily separated and re-laid elsewhere.

Laying a Kahrs wooden floor Step 1

5 Simple Steps

1. Begin in a corner and lay from the left.
A practical advantage: the gap between the long sides and the wall can be adjusted later, when three rows have been laid.


Laying a Kahrs wooden floor Step 2

2. Press the next board at an angle to the first and at the same time lay it onto the floor.
The rows align themselves automatically. 
Cut the last board in the first row to the correct length, and start the next row with the piece left over.


Laying a Kahrs wooden floor Step 3

3. Press the board at an angle to the board in front. 
Push the board forwards, simultaneously pressing it down gradually onto the floor.
