Our New Era Ultraslim System can be laid with a build-up of only 60mm from the base to the finished floor level. This is achieved with a specially designed low-level cradle and 22mm thick battens. The new system is ideal for replacement floors and refurbishment projects where the subfloor may be uneven and the floor finish height is restricted.
For uneven subfloors, a height range from 60mm to 72mm is achievable. Our New Era Ultraslim system provides a “sprung” floor when used in combination with Junckers 22mm solid hardwood floor boards. It’s been fully tested and certified to EN 14904 category A4 for area elastic multi purpose sports floors.
The new cradle is called the “S Zero”. System data:
For 411mm Batten Centres:
– Batten size: 22mm x 45mm x 2400mm; Junckers Laminated spruce battens, 2.7m of batten required per sqm of flooring. – Cradle centres: 300mm, which equates to 10No cradles per sqm of flooring – Maximum thickness of packing in cradle; 12mm – Uses standard range of New Era plastic packing pieces for levelling; 1.5mm, 3mmm, 6mm and 12mm sizes.
In his series of articles highlighting technical issues to do with wood flooring and woodcare, our Technical Manager Richard Aylen explains how wood dyes and colouring processes work
One of the many reasons why beautiful timber floors have been around for so long is that they blend perfectly with many styles of interior. In common with other natural materials, timber may be used next to a wide variety of other colours and textures. The colours that nature provides are very familiar to most of us, but we can create even more choices by using stains, textures and colouring processes.
What options are there if you’re looking for a floor with a coloured finish? It might be a new floor or refurbishment of an old one – there are a few popular choices, each with its own pros and cons.
For refurbishments, a decision must be made if the products to be used will be from one manufacturer that are guaranteed to work together. Alternatively, there is the option to “mix and match” using wood dye from one supplier and lacquer from another. If the latter method is chosen, the flooring contractor needs to guarantee that the products offered are compatible. If in doubt, always do a test area and be aware of the risk that manufacturers sometimes alter formulations… so what works today may not necessarily work tomorrow. The timber species may also affect the result. Some water-based finishes may not perform well on naturally oily tropical hardwoods, but will be perfectly fine on traditional species such as oak and ash.
Let’s look at some of the choices that are available for customers who want to add colour their floors.
These will usually be water-based and used instead of a clear primer. As well as providing the desired colour, the primer will reduce the “gluing effect” that can occur with water-based finishes. A good, and very popular, example is Junckers Prelak White.
Primers provide an even, transparent “wash” effect and work well on wood that may have a patchy finish if a conventional wood dye is used e.g. maple or beech. Skill and care are needed during application to avoid overlaps, especially on darker, parquet style floors. The primer needs to be over-coated with clear lacquer and it is safest to use a lacquer recommended by the primer manufacturer.
Not strictly a coloured finish; “Invisible” primers and lacquers are fairly new to the UK market. They are used where the final colour of the floor needs to be as close as possible to bare sanded wood. Their “invisibility” works in two ways; one, that they have a very “flat” matt surface which gives the impression that the wood has no coating. Secondly, they change the colour of the wood very little. That said, these are often normal properties of many water-based primers whether marketed as “invisible or not. Best results are achieved on light coloured timbers as some colour change will be seen when applied to very dark woods.
These are low-solids, fast drying products, not to be confused with coloured varnishes or “wood stains”. They must be protected with lacquer. The “rule of thumb” is that if the wood dye is organic solvent-based, a water-based lacquer is most likely to be suitable for overcoating, and vice versa. This must not be fully relied upon though, and a test area should always be done prior to treating the whole floor. Often, the lacquer used to over-coat the dye will be from a different manufacturer.
Dyes are easy to apply using a cloth or pad and it is fairly easy to avoid overlap marks etc. They are fast drying, so the first coat of lacquer or primer can be applied soon after. Bear in mind that stained floors may be difficult to patch repair – especially if the colour has faded over time and may appear patchy on certain types of wood eg maple, beech.
Oils often produce a uniform colour on beech, maple etc. compared with wood dyes. They tend not to be prone to application issues such as roller stop marks and work well on herringbone and parquet floors. Oil can be used on its own or may be used as a primer and then over-coated with lacquer. Check that the oil is compatible with lacquer – some are not. Junckers Rustic Oils may be used either as a full treatment or over-coated with HP Commercial lacquer. Oils tend to have a longer drying time than a primer or wood dye.
The Effect of Sheen
Many customers will prefer matt finishes on textured and
coloured boards as this tends to look more natural, although this is largely a
matter of current taste.
Vacuum coloured floor boards
For a very consistent and permanent coloured finish, some types of timber lend themselves well to vacuum staining. Here, the colour of the wood itself is altered by using a chemical or staining process. This affects the board through the majority, if not all its thickness. So when the floor is sanded there is no need to re-apply the colour treatment. Fumed oak, or Black Oak, is perhaps one of the better-known examples of this. Junckers has also used this process on beech to make its Sylvaket boards, and has extended the process further by vacuum staining with water-based wood dyes.
The ever-increasing choice of finishes has led to an increased demand for ‘the perfect shade’, a perfect match to another design element of the interior. It’s always important to assess the use of the floor, estimated foot traffic and maintenance issues before recommending one choice or another – that’s where the expertise of a professional flooring contractor comes in. Our network of Approved Flooring Contractors and Approved Maintenance Contractors might be able to help!
This really isn’t something you see every day – a wooden floor installed in a circular pattern, a concentric dodecagon (yes, we had to look it up too!) to be precise. The famous Spanish City in Whitley Bay has undergone major refurbishment works, which includes new solid wood flooring from yours truly. Architects, ADP, brought the seaside pleasure building back to its former glory by carefully restoring the original decorative features in the Grade II listed building.
The works included revealing the magnificent dome in the rotunda by removing a mezzanine floor, restoring the triple height ceiling to create a large, circular space. The grand room required a complimentary floor and the choice fell on our Black Oak, fitted in the aforementioned pattern. Installed by Junckers’ Approved Contractor Stenhouse Flooring, the project features mitred joints which require a high level of skill and experience.
This is an extraordinary project with a very complicated flooring installation. The lines of the concentric dodecagon pattern on the balcony continues in the floor in the circle below (see images). On the balcony, the mitred boards run from column to column and downstairs from columns on the outer circle, where there is a step down, towards a centre point in the middle fitted with a small section of paler oak (just visible underneath the grand piano in the main image). There are 12 identical sections that form the circle, each segment overhung, angles adjusted to fit perfectly with the previous piece, mirrored in all sections. Every mitre was hand cut and hand routered, grooved with false tongue so the whole floor is connected. Over 2000 cuts in total.
The work to approximately nine weeks and required two highly skilled floor layers. The floor is finished with Junckers Oil to allow for spot repairs without much downtime and minimal disruption.
Junckers’ solid wood flooring was also installed in several other areas in the building, which now includes bars, shops, restaurants and a suite of rooms for events, conferences and weddings.
Our thanks to our Approved Contractor Stenhouse Flooring for the detailed information, and a for job well done!
Last week we showed off our Hexparket flooring alongside a whole host of Danish design brands at London Design Fair. The Danish Country Pavilion was initiated by the Embassy of Denmark in London, who curated a real-life Danish Living Room full of furniture, lighting, homeware and sound, with our Hexparket floor forming the backdrop.
A celebration of Denmark’s strong tradition of design and craftsmanship, the large stand brought together well-known iconic brands and promising new talent. Thousands of visitors from the global design community came along to discover the room and learn more about the individual companies represented. Styled by the talented women who run Arttiles, Trine Galschiøt and Anette Nørmark, the overall design presented as a cohesive look with elements from many different sources, just like in a real home.
Throughout the room, the emphasis was placed on exquisitely crafted pieces, using quality materials. Made in solid wood, the hexagonal design of the Hexparket floor showcases Junckers’ own long-standing tradition for quality and craftsmanship with a contemporary take on the classic parquet floor. The geometric shapes of the large hexagonal staves combined with the structural grain patterns of the timber contrast beautifully.
Danish design brands represented in the Danish Living Room included:
Arttiles – handmade tiles
BoConcept – furniture
Dottir Nordic Design – ceramics
Danish Fuel – bar cabinets made from fuel cans
Eberhart – furniture
Libratone – sound
LOP – furniture
Made by Toft – furniture & home accessories

Spekva – furniture
Tom Rossau – lighting
Warm Nordic – furniture
Hexparket by CarpEnter Cph & Hartmann. Hexagonal staves made in solid oak are laid to form an intricate design mimicking nature’s own geometric pattern based on equilateral triangles. The staves measure 370mm on all sides by 20.5mm thick, with an untreated surface to be finished on site. The natural grain structure of the timber adds texture and interest resulting in a lively, elegant floor.
Traditionally, timber floor finishes and heating systems are specified separately and supplied and installed by different companies. Junckers Leveldek offers a versatile levelling system, underfloor heating and a solid hardwood floor finish from a single point of supply.
We have teamed up with one of the main heating component manufacturers to offer a combined solid hardwood floor and heating system which achieves the best fit in terms of ease of installation and efficiency.
The Junckers Leveldek system is a fully integrated solid hardwood floor and heating system. Any of the 22mm or 20.5mm thick floor boards from our full range of finishes may be used, so there is a floor to suit any taste and style of interior.
Junckers hardwood floors have for many years been recognised as the only solid hardwood floors which are so stable that they are guaranteed for use with underfloor heating. This is something that architects, the flooring and heating industries have known for the last 30 years or so. It is fair to say that almost any type of underfloor heating may be used with Junckers floors. However, heating designs vary enormously with different ways of supporting the pipes and insulating the floor, and careful planning is needed when coordinating heating and flooring trades on site. There can also be some significant efficiency and running cost differences between one system and another.
Energy Efficiency and Fast Warm Up
A Junckers Leveldek floor system is able to achieve the greatest energy efficiency and fastest warm-up time because of the unique way the heating pipes are supported directly beneath the floor boards. The heating panels are insulated and reinforced, and have aluminium heat diffusion plates. They are pushed upwards against the underside of the floor boards by the support saddles and this close contact gives the best heat output possible. This also means that the Leveldek heating pipes cannot sag or move, so the heating will give the same reliable efficiency for its whole life. The design of the Leveldek system means that the response time and heat output can be calculated accurately, so the heating engineer can be sure that the predicted performance will be what the client will actually get.
The heating panels and battens are supported above the subfloor, therefore it is very easy to include other services beneath the floor prior to installation of the hardwood floor boards. Junckers Leveldek works perfectly when a sprung floor is needed because the heating panels will flex along with the whole floor system.
Leveldek – Many Solutions in One
There are many ways the Junckers Leveldek system can be used. It is based upon one of Junckers’ established levelling systems, so the subfloor can be a screed, concrete slab, block and beam or other type of base; flat or not. This makes it perfect for residential and non-residential new build as well as refurbishment projects. When used with solid SylvaSport beech flooring, the system provides a sprung floor to EN 14904, which means that it is suitable for sports, dance and activity halls and meets the requirements or Sport England and Sport Scotland.
Environment and Sustainability Considered
As well as providing an energy efficient heating system the materials which are used for Junckers floors are from sustainable certified sources, are fully recyclable and manufactured to the highest environmental standards. Even the energy which is used to power the flooring factory is produced from waste wood from flooring manufacture.
Our long experience and unique reputation means we are able to offer a full guarantee for the system under the Junckers Lifetime Warranty Scheme with a 25-year guarantee for the flooring and installation, 10 years for the heating pipes and insulated panels and 2 years for all electronic components.
Hexparket by CarpEnter CPH & Hartmann is a new parquet floor from Junckers. Hexagonal staves made in solid oak are laid to form an intricate design mimicking nature’s own geometric pattern based on equilateral triangles. Made in 100% solid hardwood oak, the staves measure 370mm on all sides by 20.5mm thick. The staves have a groove on each side and an accompanying loose tongue is used in the installation process.
Hexparket is delivered with an untreated surface to be finished on site with either a lacquer or oil. Made in Junckers’ most popular timber grade, Harmony, the floor has a natural appearance, few knots and some colour and structural graining variation between the individual tiles. Oak is a hardwood species characterised by being hardwearing and is therefore very suitable for flooring. The wood has a warm and golden glow, an interesting grain structure and over time the natural ageing gives the wood an authentic appearance. The graphic look and clean, sharp lines of the new Hexparket is perfectly counter balanced by natural beauty and texture of the timber, resulting in a lively, elegant floor.
Danish design house Republic of Fritz Hansen has chosen Junckers Oak Boulevard for its HQ showroom. The company’s classic designs are now displayed against a backdrop of Junckers’ widest dimension floorboard, measuring 185mm wide made in solid oak.
The many world famous classic pieces and contemporary designs made in collaboration with leading international designers sit perfectly on Junckers’ signature long-length planks, which add a further architectural dimension to the space. Finished with our newly reformulated UltraMatt Lacquer, the floor has a completely natural, matt appearance which looks just like an oiled finish. Developed in response to the growing trend for natural, ‘unfinished’ looking floors, Junckers UltraMatt Lacquer protects the solid wood floor, making it durable, hardwearing and easy to care for. Even though it looks just like an oiled finish with no surface sheen, the new lacquer gives the floor superior protection against spills and scuffs. The natural, matt appearance combined with a highly durable, easy to clean surface has made UltraMatt Lacquer Junckers’ best selling finishing product – over 80% of all pre-finished floors are sealed with it.
All Junckers pre-finished floorboards are now available with UltraMatt Lacquer, ready for immediate use once installed. The new formula enhances the natural beauty of the various timbers Junckers offers, including oak, ash, black oak and beech. Junckers specialises in long-length planks – the true mark of a high quality floor, and its floors are suitable for use over under floor heating. UltraMatt Lacquer can also be bought as a finishing treatment for all types of timber.
Over 6500m2 of our Oak Boulevard has been installed in the impressive Aeroville shopping centre near Charles de Gaulle airport outside Paris, France. The €350 million project is a mixed-use retail and entertainment hub with over 200 stores, five cinemas and multiple restaurants.
With an expected footfall over up to 12 million people a year, a hard-wearing, extremely durable floor was a non-negotiable requirement. Our Oak Boulevard, a premium, solid hardwood floor with a stave width of 185mm, was laid in alternating patterns originally inspired by an African design, as an over-sized parquet floor. We think you’ll agree the effect is just stunning. Glued down on concrete, sanded and finished on site with a UV resistant lacquer, the floor adds warmth and elegance to the expansive atrium-style walkways at the same time as offering the required durability.
