FAQ

Does solid wood parquet look better than semi solid parquet?

You cannot tell the difference between solid oak parquet and lamella parquet: the top-layer in lamella parquet is made of exactly the same material as solid oak parquet and once laid, you will not be able to tell the difference.

What thickness is the top-layer?

The top-layer of semi solid parquet can vary from 1 mm up to 5 mm. High-quality semi solid parquet can last a life time. This compares to a solid wood floor with the tongue and groove 3-7 mm below the surface of the floor. Our semi solid parquet has top layers varying from 2 to 5 mm.

 

What is the length of the floor boards?

The length of the floor boards varies from 50 cm up to 250 cm where 250 cm is the standard size. Shorter pieces may be used to finish or start a row. We advise you to stagger the planks, maintaining an average of 40 cm between seems. The width of the planks varies from 16 up to 26 cm.

What is a bevel?

A bevel is a sloping 45° edge on the long side of a plank. The bevel accentuates the planks, recreating the look of slid wood parquet. FloorTeq B.V. has a standard bevel of 0,8 mm, though it is also possible to provide floor with no bevel. Floors without a bevel are completely level.

Can semi solid parquet be renovated?

Renovation of semi-solid parquet depends on the thickness of the top layer. However, 90% of parquet floors are never sanded or renovated. If a parquet floor is sanded by a professional, about 0,6 and 0,7 mm of the top layer is sanded away. The top layer may never be thinner that 1 mm, which means that semi solid parquet with a top layer of 2,5 mm can be professionally sanded or renovated twice.

Can semi solid parquet be placed on concrete?

Yes, concrete is ideal for placing semi solid parquet. It is vital the moisture content of the concrete is measured before placing the floor; this must be below 2%. If the semi solid parquet is installed floating, be sure to place an under floor which acts as a moisture barrier to prevent ground moist from getting in your floor.

Can (semi solid) parquet be placed on stairs?

Yes, (semi solid) parquet can also be placed on your staircase. This is a nice way of continuing the same floor throughout the house. Placing solid oak strips on the front will make it look beautiful and a rubber milled edge will prevent you from slipping. We advise to have your parquet staircase installed by an experienced and accurate carpenter and to make a mould of every step to ensure the oak fits perfectly onto each individual step. Paint the back and sides of the staircase white to obtain a beautiful result.

What does it mean for semi-solid parquet / Engineered wood flooring to be stable?

When wood is stable it does not warp. Solid wood is unstable, which means it’s easily affected by moisture, and may warp as a result, going crooked, bowed, kinked or twisted. Wood warping is a derivation from flatness as a result of stresses from the uneven drying or moistening of the wood. Semi solid parquet is made up of several layers which are placed crosswise, minimising the effects of moisture and consequently minimising the possibility of warping; the floor stays flat and only minimally expands in width. This feature makes semi solid parquet a qualitatively better choice, especially when placing the floor on under-floor heating. Solid wood parquet cannot be placed on top of under-floor heating.

What are knots?

A knot in the wood is where a branch used to grown from the trunk. Branches have a different direction from the trunk of the tree and the new wood from the branch oppresses the older wood of the trunk. A knot makes the wood less strong and harder to work with. Knots come in different shapes, and can be either grown into the wood or lay loose. Loose knots can fall out of the timber whilst sawing. Loose knots are therefore considered a deficiency in the wood. Knots can be treated in several ways: they can be either taken out and the holes filled with a stopper, or it is left in the timber because of the special patterns it creates.

What is the difference between brown or black filling for knots?

There is no difference except in colour. Black filling makes the knots stand out more, and can be very pretty in combination with white washed floors boards.

 

What is sapwood?

Sapwood is the newly formed outer wood located just inside the vascular cambium of a tree trunk and active in the conduction of water. It has the same structure as heartwood, but a different chemical composition: it lacks the protective chemicals of the heartwood, and sapwood is usually lighter in colour than heartwood. Sapwood is sensitive to mould and is therefore not used (when untreated) when durability is required.

What is wood grain?

Wood grain is the internal direction of the wood. The direction of the wood grain can be seen on a piece of wood which is cut along the axel of the tree trunk. In most cases the wood grain run parallel to the tree’s axel. This wood is called straight grain. Other types of wood grain are:

Spiral grain is wood grain which spirals around the axis of the tree. Spiral grain often causes planks to go twisted.

Interlocked grain is wood grain which also spirals around the axis of a tree, but regularly reverses its direction, alternating directions and thus interlocking the wood grain. This makes the wood difficult to plane in some directions. However, quarter-sawn wood with an interlocked wood grain gives a very beautiful effect after sanding and lacquering the planks. Interlocked grain is especially found in tropical wood species such as sapeli, azobé and bangkirai.

Curly grain occurs when the longitudinal cells grow in waves. If you split this wood through the heart of the trunk it will look like a washing board. When sawn into planks and planed, the waves can still be seen. Because of the way the waves reflect the light, the grain creates a transversal stripe effect. This shape is often seen on musical instruments, such as the back of a violin. Curly grain is commonly found in maple, birch, ash, jarrah, walnut and makoré.

Bird’s eye wood grain is capricious and irregular; its distinctive pattern resembles small eyes disrupting the smooth lines of the wood grain. It is difficult to cleave this type of wood. When finishing bird’s eye planks with a walnut veneer, this rare and beautiful pattern is accentuated.

When fabricating floors it is important to keep the type of grain in mind. Depending on the use of the floor some types of grain may be more or less suited.

What is heartwood?

Heartwood is the non-living, older wood of a tree, generally darker and harder than sapwood. Its main function is the support of the tree and unlike sapwood, it no longer conducts water. Heartwood contains chemicals which make it resistant to negative influences such as bacteria and mould.

Is it possible to install the floor yourself?

Absolutely. Using the instructions found on our website you can install the floor without the help of a professional. The instructions describe all the steps and facets of placing a floor.

Which is the preferred method for installing the floor?

Both floating and glued instalment are good and can be done on both smaller and larger surfaces. A floating floor will feel like a real solid wood floor, whereas a glued floor will make a stronger sound when walked on. Floating floors are placed in apartments for its noise-reducing effect.

Can semi solid parquet be placed on top of under-floor heating?

Yes, semi-solid parquet can be placed on top of under-floor heating, as long as the following criteria are met:

  • The pipes of the under-floor heating should not be too far apart from each other, or they should be placed deep into the concrete, this to ensure an equal spreading of the heat.
  • The entire floor must be heated; there may not be any cold areas.
  • It must be possible to regulate and control surface temperature.
  • The surface temperature of the under laying concrete may never exceed 27°C.
  • A moist barrier must be placed between the concrete and the parquet.
  • Air can dry out the wood. Make sure the space between the concrete and the parquet is airtight.
  • When placing the semi-solid parquet, the under-floor heating must be on at a temperature between 18°C and 22°C.
  • Air humidity must be between 45% and 60% before, during and after installing the floor.
Should I use an expansion joint when installing semi solid parquet?

Yes, as is the case with all wooden and laminated floors (such as semi solid parquet), the floor needs enough room to warp. This is necessary everywhere where the floor meets a set object such as a wall, doorposts, pipes etc. As a rule of thumb, 3mm expansion should be kept for every meter in width and 1,5mm should be kept for every meter in length. When a floor is more than 20 x 8 meters, an expansion joint is necessary every 8 meters in width and 20 meters in length.

What is the best direction to place a parquet floor?

Technically, there is no preferential direction in which to install the parquet. Directionality is completely open to personal taste and aesthetics. The parquet will look best when placed in the direction of the main source of light and in the direction of the main entrance to the room. If a room has two windows on adjoining walls, the floor is best placed following the long side of the floor.

Can semi-solid parquet be placed in bathrooms or humid rooms?

Bathrooms and other humid rooms are not adequate for semi solid/ solid parquet. It may be placed in kitchens or toilets as long as spilled water is dried immediately.

Can I place a carpet on top of semi solid parquet?

Yes, a carpet can be placed on semi solid parquet. However, it is important to place a special underlay under your carpet before placing it on the semi solid parquet to enable the wood to breathe. Also, wood naturally changes colour when exposed to UV (sun) light. To make sure the floor does not show discolouration in certain areas, we advise you to move or remove the carpet from time to time, giving the wood under your carpet the possibility to gain the same colour as the rest of the floor.
