Schlüter specification insight: minimising build-up in the manor

Schlüter-Systems used its specialist technical knowledge and a number of key product solutions to minimise floor build-up and guarantee complete waterproofing provision in the refurbishment of one of Ireland’s most magnificent country houses.

Gallery

Set in 840 acres of grounds, Adare Manor has been the subject of an 18-month-long renovation – its most extensive in 25 years. 40 new bedrooms have been added to this 19th-century Neo-Gothic masterpiece as well as a host of new facilities; including a swimming pool, boardroom, cinema, spa and 350-capacity ballroom.

Company involvement

Stone was extensively specified as part of the project. Schlüter-Systems was initially engaged to provide a waterproofing solution for Adare Manor but was eventually able to assist on a greater scale.

Insight

Area: bedrooms and bathrooms (floors)

Action: minimising height for uncoupling, underfloor heating and waterproofing.

Through the use of multi-functional products, Schlüter was able to put forward a single-source solution that reduced build-up from 10 layers to six and saved 19mm of height, as well as eliminating the need for a smoothing compound. The floor build-up was approved by lead architect, ReardonSmith, and main contractor, John Paul Construction.

Underfloor heating, uncoupling and waterproofing – four layers to one

Underfloor heating, uncoupling and waterproofing provision was simplified from four layers to one, using the electric underfloor heating system, Schlüter-DITRA-HEAT-E.

Schlüter-DITRA-HEAT matting is only 5.5mm thick and was laid onto a 1mm bed of flexible adhesive, giving build-up of just 6.5mm. As opposed to needing a layer of encapsulation above it, the system features studded matting and the cable clips securely within it, avoiding the need for tape or adhesive and enabling even spacing.

Acoustic matting – a slimline variant

Schlüter assisted by exchanging the proposed matting of 10mm thickness for Schlüter-DITRA-SOUND matting of only 3.5mm thickness, saving 65% of build-up for acoustic reduction measures. This matting offered the same dB rating and could be installed using a standard polymer modified adhesive.

Area: bathrooms/golf clubhouse, including the spa (walls)

Action: providing guaranteed waterproofing.

For areas of high moisture, waterproofing is an essential consideration, and it takes on an even greater significance when it comes to preserving historic buildings – Adare Manor has stood for 185 years, and the intent of the restoration is to see it through at least the same again.

A secure waterproofing system

Schlüter’s complete waterproofing system for these areas consisted of Schlüter-KERDI-200 waterproofing membrane, KERDI-KEBA sealing band and KERDI-COLL-L adhesive. These products work together to form a CE-Marked waterproof solution that will stand the test of time.

As well as the above solutions, Schlüter-Systems also provided its original uncoupling mat, Schlüter-DITRA 25, for use under the flooring of Adare Manor’s new ballroom and its golf clubhouse and spa. The company is proud to have been specified on such a scale for this prestigious project.

An artistic uncoupling of tile at Tate Britain

1300m² of Schlüter-DITRA 25 uncoupling membrane helped to ensure a crack-free finish for the tile within 2016 Turner Prize nominee Anthea Hamilton’s recent commission for the prestigious Duveen Galleries.

One British artist a year is invited to produce a new work for the signature space, which constitutes the heart of one of the UK’s most famous art galleries. Hamilton’s response, entitled ‘The Squash’, combined performance and sculpture in an immersive experience.

The installation involved tiling the length of the Duveen Galleries. Contacted by curator Linsey Young, Schlüter donated its market-leading uncoupling membrane for use beneath the white tiles laid above the galleries’ terrazzo floor. The Schlüter-DITRA 25 was installed and tiled over the days and weeks in the run-up to the exhibition opening on 22nd March. Creating a striking contrast with Tate Britain’s Neo-Classical architecture, the commissioned work remained in situ until 8th October, following a six-month run.

One performer per day took to the tiles from 10am to 6pm, clad in their choice of one of seven costumes designed by Jonathan Anderson, Creative Director of luxury clothing and accessory brand, Loewe. All were inspired by different types of squash and pumpkins, taking their lead from Hamilton’s initial source of inspiration for the commission: a 1960 photograph that she discovered several years ago, capturing a scene from a dance by American Choreographer, Erick Hawkins.

The project marked Schlüter-Systems’ second involvement with Tate Britain; in 2011, the company was engaged as part of a £45m renovation of the Grade II Listed Millbank building, led by architecture firm Caruso St John. The renovation involved the creation of new education and events rooms, including the art gallery’s Djanogly cafe and opened in November 2013.

DITRA 25 was again utilised, on this occasion for uncoupling provision beneath agglomerate stone or unglazed porcelain floor tiles, dependent on the rooms and areas in question. Cement-free tile backer board, Schlüter-KERDI-BOARD, can be found supporting wall tiling in the WCs and kitchens; Schlüter-DILEX movement joints, in a number of variants, can be seen within the floors and walls of these areas, helping to maintain crack-free coverings.

Whether supporting a renowned artist through sponsorship or providing solutions for permanent features, Schlüter-Systems is delighted to play a role in the endeavours of Tate Britain.

Product in focus: Schlüter-BEKOTEC-THERM

Schlüter-BEKOTEC-THERM is a lightweight, low-height wet underfloor heating system suitable for a wide variety of projects, including renovations.

The Schlüter-BEKOTEC-THERM can be specified with heights starting from as low as 20mm before floorcoverings. Other benefits of this innovative system include:

Material and weight savings

The BEKOTEC-THERM system is considerably lighter than conventional heated screeds. A reduction of 37mm in screed thickness saves 3.7m³ of screed mortar (equivalent to a 7.4 tonne saving over an area of 100m²).

The small screed mass and proximity of the heating pipes to the surface means that the system is quick to respond and, therefore, more energy-efficient.

Low tension screed construction and crack-free finish

The system is based on the Schlüter-BEKOTEC family of lightweight modular screed systems. The studded pattern of the panels prevents buckling of the screed; this, in turn, avoids the build-up of tension. As a result, no screed joints are required in a floor assembly using the BEKOTEC system. Paired with the Schlüter-DITRA 25 uncoupling membrane, the system prevents stresses from transferring to the covering. The overall result is a long-term crack-free finish.

Short construction periods

The four weeks that a traditional screed takes to dry and cure are reduced to just one to two days when using BEKOTEC. The DITRA 25 uncoupling membrane can be installed as soon as the screed is ready to bear weight, followed by the tile or stone covering. These factors result in quicker progression and less disruption to the project as a whole.

When it comes to putting the BEKOTEC-THERM system into operation, warm-up heating can be started at 25°C and increased by 5°C per day until the desired system temperature is reached.

Compatible with renewable energy sources

Reduced screed mass means that the system can run at lower temperatures of around 30°C (versus up to 50°C with systems that use traditional screeds). The lower supply temperatures mean that the system is a great match for renewable energy sources, such as ground and air source heat pumps.

Wet underfloor heating design service

Using existing floorplans and project heat calculations, Schlüter-Systems can provide a design for your project and make sure that the desired room temperatures can be achieved.
