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.
Cottrell + Vermeulen Architecture has designed new, bright and airy postgraduate accommodation for Churchill College, Cambridge with interiors featuring Junckers’ solid maple flooring. Cottrell + Vermeulen won a competition to design the new buildings, 16 years after the studio completed a housing scheme on a neighbouring site.
The 35 new units of accommodation comprise five studio flats and 30 en suite rooms with spacious communal areas on each floor, spread across three buildings. The design builds on the original architectural scheme, designed as an extension to CVA’s previous work on the site. The architects sought to recreate the warmth and brightness of the original college rooms from the 1960s and found our maple flooring a good match.
The choice of two-strip boards, where two staves of wood make up one floorboard, was also a reference to the narrow boards used in the original rooms. The naturally pale tone of the maple floor is matched by joinery in birch faced plywood to form a comfortable and welcoming space, ready for students to move into at the start of the new academic year. The floor was installed by our Approved Contractor VA Hutchison Flooring.
Quiet floors in multiple occupancy buildings
An important consideration for student accommodation is how impact sound travels through floors
from one dwelling into another. Building regulations set out minimum standards for impact and
airborne sound through floors which apply to residential buildings and buildings converted to new
uses, including hotels and care homes.
The floor finish will usually act in combination with other elements of the building to achieve the
target levels of sound insulation. The design of the subfloor and ceiling beneath play an important
role, as does the way the floor finish may need to be isolated from the walls that surround it, but
there is no question that the right acoustic floor will control the transmission of impact sound.
We have a range of acoustics systems available which comply with building regulations. The newly updated New Era acoustic system is a height adjustable system for use on structural concrete slabs, block and beam floors and almost any other type of sound, dry load-bearing base.
The New Era system uses acoustic cradles with 10mm thick recycled rubber pads, factory-fitted to
the underside. The cradles are height adjustable using purpose-made packers, supporting laminated
timber battens. 50mm thick mineral wool insulation is placed between the battens and Junckers
20.5mm or 22mm thick solid wood floorboards are fixed to the battens to complete the installation.
The use of 36mm thick battens achieves an impact sound reduction of 27dB; and a 48mm thick
batten achieves an impact sound reduction of 28dB, thus complying with building regulations.
For Junckers 14mm thick sold wood flooring installed with Junckers’ Clip System, an impact sound
reduction of 19dB can be achieved with Junckers’ 5mm thick CA2 Acoustic Underlay, loose laid with
the floorboards installed on top as a floating layer, no fixings required.
All our floor system specifications are available on NBS Plus and draft NBS clauses are available on request. We also provide BIM Objects for all systems. Junckers solid hardwood floor systems are guaranteed for 25 years when installed by a Junckers Approved Contractor. Junckers Approved Maintenance Contractors offer a care scheme where the client’s floor is periodically inspected and maintained so as to keep the floor in good condition and to maximise its life.
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!
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
Mobel og Rum – homewares
Morso – wood burning stoves
Noorstad – furniture

Republic of Fritz Hansen – furniture
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 found in castles and stately homes, solid wood floors laid in geometric patterns evoke a sense of a timeless elegance and style. In the last decade, parquet floors have seen a sharp rise in popularity and today a herringbone (or chevron, basket weave or ladder pattern) floor is almost de rigueur, the floor of choice for hotels, bars, restaurants, retail and office spaces as well as private homes.
Herringbone, which is the most popular parquet floor, is made up of rectangular wood blocks, or staves, arranged in a pattern resembling fish bones. Junckers’ new Twin Herringbone wooden floor is an updated version of this much-loved classic. With Junckers’ trademark commitment to quality and craftsmanship, Twin Herringbone is a solid hardwood floor – as durable and long-lasting as a traditional parquet floor.
Made from Junckers’ classic two-stave flooring, each board consists of two rows of staves; one full-length and one with two half-length staves. This gives Twin Herringbone an authentic pattern and elegant look but at a very good price point. Delivered with a hardwearing factory-finished surface ready to walk on as soon as it is installed, Twin Herringbone has the advantage of saving on costly and time-consuming installation work as the floor does not have to be sanded, filled and treated after being fitted. A pre-finished floor is far superior in terms of durability with optimal wear resistance and a uniform appearance. It also has a significantly shorter installation time compared to an unfinished floor, with minimal inconvenience.
Available in solid Ash, Beech, Oak and Black Oak in a choice of matt or silkmatt lacquer or oil, as well as a large selection of colours. Each stave measures 129mm wide x 516.6mm long x 14 or 22mm thick. Ideal for use in all rooms of the house except bathrooms and can be used with all major underfloor heating systems. Twin Herringbone feels warm and solid underfoot, free from gaps or crevices.

Next month, we’re working with The Danish Embassy in the UK and the Trade Council of Denmark to celebrate Denmark’s strong design heritage at London Design Fair.
From 20-23 September, our hexagonal parquet floor Hexparket by CarpEnter Cph & Hartmann will form the backdrop to the ‘Danish Living Room’, a curated showcase of iconic brands and promising new talent from Denmark.
A few years ago, our professional lacquer was used to restore the floor at the Danish Embassy in London to its former glory. The existing solid wood floor in the expansive apartments was sanded back then refinished with four coats of our water-based lacquer, adding an elegant, subtle sheen to the wood as well as hard-wearing, long-lasting protection. A rare peak into this beautiful home in London.
A white solid oak floor with wide board, long-length planks adds a bright, space-enhancing backdrop to an interior, making the most of natural light by reflecting it back into the room. At 185mm wide, Oak Boulevard is our widest floor board, made in solid oak, through and through.
Rustic White is an oil which allows the naturally occurring grain pattern of the timber to show through, leaving a natural look. The oil has a completely matt finish and it can be over-coated with Junckers’ Ultramatt lacquer for an even more durable surface, to protect against scuffs and spills.
700m2 Rustic White Oak Boulevard was recently installed in three of the luxurious apartments at The Silo, a prestigious development in Nordhavn, Copenhagen. We think the images speak for themselves, don’t you?
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.
A prestigious residential development in the fashionable Clapham Old Town area of London features over 700m2 of Junckers’ Black Oak flooring. Designed by Assael Architecture, the development combines converted 19th century warehouse buildings with contemporary architecture.
The high quality, modern interiors combine a palette of rich, natural materials where Junckers’ solid hardwood floors add warmth and texture to the inviting spaces with the matt, oiled surface the perfect backdrop to the stylish decorating schemes. Black Oak Oiled has the appearance of an aged floor, with a rich patina and surface texture, highly sought after in the design industry.
Junckers wide board floors come in long-length planks, a true mark of a high quality solid hardwood floor. In addition, our floors are ideal for use over underfloor heating. Thanks to a unique drying process developed over many years, Junckers floors are very stable and have a low moisture content. Tried, tested and approved by all major underfloor heating manufacturers, Junckers’ solid wood floors have been successfully used together with underfloor heating for decades.
