REHAU’s RAUTITAN offers royal solution for luxury Edinburgh apartments

REHAU’s RAUTITAN universal pipework offered the ideal solution for a difficult project. The pipework has been installed in 13 luxury apartments, located on Edinburgh’s Royal Mile.

The 123 High Street development being delivered by Unicorn Properties is a four-storey building being built above three traditional stone buildings, in the last gap site on the Royal Mile in Edinburgh. The development
will create 13 two-bedroom premium apartments, boasting quality fittings and finishes throughout and a
prime city centre location close to Edinburgh Castle and the city’s other major attractions.

The building has been constructed on top of a concrete deck which sits above the High Street’s listed properties and much of the structure is made of timber. The extensive use of wood was a problem when it came to the specification of plumbing pipework for the apartments, as it ruled out the use of traditional copper piping.

the 123 High Street project was that the new pipework needed to be run through wooden joists.” Consequently, polymer piping offered the ideal solution as it was easier to install, due to its inherent flexibility, and required no hot work near the joists.

RSP specified REHAU’s RAUTITAN universal pipe solution for the 123 High Street job. RAUTITAN can be used for radiator connections or installations through floors, skirting boards and walls, but is also fully certified as hygienic for drinking water and has a smooth inner surface to prevent deposits from forming in the pipe. Furthermore, when used with REHAU’s joint system, it offers cavity-free impermeable joints which eliminate the risk of microbial contamination and the possible growth of legionella bacteria.

Main contractor, Colorado Group was keen to ensure that the pipework was reliable. David McGinigal, Director at the Colorado Group comments: “I have been really impressed with REHAU pipework and the joint system on previous projects so when we were choosing the specification for the 123 High Street project and we needed a polymer pipe alternative, I knew that the combination of RAUTITAN pipework and compression sleeve joints would be a great solution and would also guarantee no leaks – which was something we had discussed at length with David at Colorado.”

Lengths of RAUTITAN pipework are joined together using the compression sleeve jointing system,
which produces a permanently sealed joint without O-rings. Using the specialist RAUTOOL device,
installers simply expand the pipe end, insert the fitting and apply the compression sleeve. 

Andrew Cooper, Director at Fusion Mechanical, said: “We have used other REHAU products in the past
on commercial contracts so we were familiar with the compression sleeve jointing, although this was the
first time we had used it with the RAUTITAN pipework.”

REHAU ensured the job was as easy as possible by offering product demos with two RAUTOOLs and organising a RAUTITAN supplier, meaning teams could be working on two different apartments at the same time and ultimately reducing installation time.

The installation offered full peace of mind with zero leaks reported for over 750 million fittings of the joints. Also, as it is made from high-grade PE-Xa RAUTITAN it promises durability for up to 50 years.

RAUTITAN is available in fully flexible and rigid options, with pre-insulation if required for pipes between
16 and 25mm in the Flex range and 16-63mm in the Stabil pipes, offering installers a solution for
virtually every application.
