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.
We are very proud to have supplied our solid timber floors to this amazing project which recently won a Wood Award, the Education and Public Sector 2018 category and was also shortlisted for the prestigious RIBA Stirling Prize 2018.
The Sultan Nazrin Shah Centre by Níall McLaughlin Architects is a graceful addition to the listed parkland at Worcester College, Oxford. The striking contemporary building houses new conference and events facilities. With a high-end finish throughout, the building houses a large lecture theatre and dance studio fitted with Junckers Oak Boulevard flooring. With a plank width of 185mm, Oak Boulevard is our widest dimension board, an elegant and durable option for a public building.
