Contemporary looking anthracite grey foiled windows in REHAU TOTAL70 PVC-U profile helped the beachfront Harbour Green development in Portobello, Edinburgh make it into the final in the Apartment Development of the Year category at this year’s Scottish Home Award. More than 300 windows and 100 doors in the 55 apartments were fabricated and installed by Motherwell based commercial specialists Walker Profiles for MNM Developments. Floor to ceiling windows and french doors were chosen for many of the one, two and three-bedroom apartments, maximising the light in the open plan interiors and giving views for residents.

One of the first replacement projects of this kind, the original steel pipework at two social housing developments in the city has been replaced with REHAU’s RAUVITHERM specialist pre-insulated polymer pipework. The Sheffield project involved the replacement of pipework in two separate networks feeding nearly 170 properties in total. On one of the projects, all of the distribution pipework from the plant room into the individual properties has been replaced, using a variety of pipe sizes from the extensive RAUVITHERM range. The installers were RJ Utility Services and the main contractors on the project were Denton and Nickels

REHAU Polytec 50 uses a conventional transom/mullion construction with box steel stick sections faced internally with PVC profile and externally with aluminium, was specified by Cooley Architects. Alongside the curtain walling, SEH also installed more than 130 windows in the 34 apartments in the Greenlaw Court block fabricated in the flush fitting REHAU TOTAL70R fully reversible window system. These replaced the original steel windows from the 1960s, replicating the overall appearance and opening options but offering the block’s residents improved thermal performance, better acoustics and greater security. The feedback from the Residents Association has been nothing but positive

REHAU Heritage vertical sliders manufactured by specialist fabricator Roseview Windows were installed in a block of 12 flats overlooking Eastbourne’s seafront as a result of a successful planning appeal by the property’s owner. “While the conservation officer refused our original application in 2013, the material we provided during the appeal helped to convince him that the REHAU Heritage vertical sliders were a suitable choice and, now that they are installed, the windows look truly stunning.”

The REHAU AWADUKT Thermo ground – air heat exchanger & GENEO® windows and doors have been installed in only the third office in the UK to be fully certified to Passivhaus standard. 27 windows and four doors from the GENEO® system were installed in the £1.5m, 680m² Passivhaus office, the majority were across its south facing aspect to increase solar gain in winter and minimise the requirement to generate additional heat. The 86mm REHAU GENEO® window is manufactured using 100% recyclable RAU-FIPRO® fibre composite material. This material enables the six chambered REHAU GENEO® system to perform without requirement for steel.

The Thermally Activated Building Structure (TABS) is at the heart of newly opened extension to Tate Modern. The new building with its distinctive perforated brick lattice façade was designed by architects Herzog & de Meuron The TABS concrete core tempering solution effectively transforms the slabs into huge thermal stores for cooling the gallery space. Groundwater is being used to circulate through the pipework to optimise the sustainability of the installation. Scoring a BREEAM ‘Very Good’ rating, the new building is predicted to use 50% less energy than a typical gallery. Generating 44% less carbon than current building regulations demand.

One of Huddersfield’s most iconic cotton spinning mills has been transformed with the installation of replacement windows fabricated in the REHAU TOTAL70c 70mm system. 110 windows replaced singled glazed timber windows across one façade of the 105 year old building. The original timber windows had become rotten and draughty and there was a danger that they could fall into the car park below. REHAU TOTAL70c windows were recommended as the ideal replacement for the timber windows because of their proven quality and durability and self cleaning glass was also specified to minimise the ongoing maintenance of the windows

Building Type: Residential development Client & Installer: Be Green Systems REHAU Product: Chilled ceiling, underfloor heating, pre-insulated pipe, plumbing Garry Woods, Managing Director of Be Green, said: “This project not only showcased our expertise but it also showcased the potential of using what we believe are now mainstream heating and cooling solutions in a domestic setting. Our aim was to show just what can be achieved using sustainable energy giving home owners low energy bills and a low carbon footprint. I’m delighted that the response from visitors has so far been hugely positive.”

Consultant: Couch Perry & Wilkes Main Contractor: Willmott Dixon Architects: Associated Architects M & E Contractors: NG Bailey Installers: Anders Heating REHAU Products: TABS, Ground-air heat exchanger, Underfloor heating Key to this performance, and to the comfort levels being experienced by staff and students, is a REHAU TABS solution which has embedded 7km of REHAU PE-Xa cooling pipes within both post tensioned ground and first floor slabs with exposed soffits. This works by circulating chilled water through the pipes to provide effective cooling in summer, countering the solar gain from the windows which are distributed evenly across the façade.

REHAU’s RAUFERNO fire rated PVC-U system won a screen replacement contract for Whitefriars Housing Association in Coventry, part of WM Housing Group. The HA’s property services department wanted to replace single glazed timber screens in 13 blocks of maisonettes with a low maintenance, thermally efficient PVC-U alternative, but decided to increase the specification to include fire resistance, in order to maximise the safety of the residents. The REHAU RAUFERNO solution was the only fire-rated PVC-U product which met this specification.
