The thermal benefits of the ROCKWOOL solution reduces heat loss and helps the hospital optimise costs by operating in a more energy efficient way. To fulfil the highest fire safety requirements for exterior cladding, Rockpanel A2 façade board was deployed to create a unique identity and authentic appearance to future-proof the building. “When it came to selecting the cladding for the project, it was a truly group-based decision,” says Richard Rhodes-Heaton. “Property Tectonics put together six different designs, and the Trust as well as the staff picked the option they preferred.

The sprawling facility spreads install an intricate roof system. over 13,000 m2, with learning taking place in workshops, training and seminar rooms. The bulk of the centre’s Thermal properties expansion took place during the 1980s. Acoustic capabilities The challenge With a goal to improve energy efficiency, most of the facility was renovated during 2017/2018. Responsibility Fire resilience for the roof areas fell to the local craftsmen from Kühne GmbH, and to master roofer, Dirk Flörke.
The solution The diversity of different roof shapes and structures meant that ROCKWOOL Meisterdach – a flexible and high-performing stone wool insulation system – was the perfect choice for the project. Not only would the roof insulation help minimise heat loss and reduce heating bills for the Centre, the stone wool would also secure fire and sound protection – both important benefits for a school environment. Viewed from above, it’s easy to see how the roofs varied throughout the facility. Kühne GmbH renovated Roof insulation a total roof area of around 5,500 m2. A sure way to increase the energy efficiency of residential and commercial properties is by “The Federal Education Centre has been expanded installing effective roof insulation. again and again.

And to add to the complexity of the project, the Get an overview of the various refurbishment needed to take place during term time types of roof insulation when school was running. The first step involved installing a ROCKWOOL vapour barrier followed by non-combustible and pressure- resistant stone wool boards. As these boards came with a factory-applied water tight membrane on the outer surface, they provided almost instant weather protection – which resulted in being very useful as the weather was particularly wet during the renovation period! When it came to insulation, the team at Kühne GmbH from Kassel laid non-combustible and pressure-resistant stone wool panels from ROCKWOOL. The insulation on top of the rafters was the perfect solution for us. The use of non-combustible insulating materials was part of the fire protection concept.” Helmhard Neuenhagen, Managing Director and Head of the Federal Education Centre
The team installed counter battens on top of the insulation layer, followed by Eternit panels. The entire roof structure was safely anchored with 300 mm long- Why do we need roof insulation? thrust screws, screwed in at an angle of 90°, and 320 70% mm long-suction screws at a 60° angle. Kühne GmbH relied on expertise from ROCKWOOL’s technical service to make the complex static calculation for the screws. Effective insulation in homes and commercial properties can reduce heating requirements by up to 70 percent1! And those that are not insulated properly can lose approximately a quarter of the heat through the roof. As well as warm air escaping, there’s the chance that cold air can also enter through a poorly insulated roof. In hot climates the opposite can occur, where keeping a building cool is essential. 35-60% Managing Director and Head of the Federal Education Center, Helmhard Neuenhagen (right) and Head of Special Projects Dr. Holger Schopbach (left) are looking forward to lower energy costs after upgrading the building envelope and, of course, a better indoor environment for the students.

19 Caerula Mar Club Resort – Renovating to make dreams come true At a glance: When builder Bryan Baeumler stumbled Stone wool proved to be a useful, sustainable building material when upon a decaying and abandoned resort it came to revitalising a derelict on the tropical island of St. Andros in the Caribbean resort. Bahamas, he was compelled to quit his cosy life in Canada and try to transform the ruin into a luxury escape. Circularity Robustness Acoustic capabilities
It was in 2017 that Bryan Baeumler discovered the former ‘Emerald Beach Club’, while on vacation with his wife. Located idyllically on the beach-front of the largest and least commercial of the Bahamas islands, St. Andros, Baeumler could see incredible potential in the space. Although it had been closed and derelict for eight years, he was completely captivated by the ruined resort – to the point that he decided to invest everything he had into revitalising the neglected buildings with a goal of transforming them into the ultimate luxury resort. Sounds like the plot of a spell-binding television show? That’s exactly what it became. Not only is Baeumler a talented builder himself, he is also the face of all things DIY and construction-related on Canadian T.V. The cult series follows Baeumler and his family, leaving their home and all things familiar to relocate to the Bahamas, chasing a dream of creating and running a luxury boutique resort in paradise. The challenge Guests escaping to a luxury island retreat such as Stone wool – A truly Caerula Mar want to feel at one with nature – while circular material enjoying every modern convenience of home and more.

The water alone used to quench the fire could fill six stand- ard car trailers! By the time the fire was extinguished, the roof and interior were completely destroyed. The investigation carried out by the fire department in the aftermath showed that the trigger occurred during work on the historical facade when a painter tried to remove acrylic resin paint using a Bunsen burner. The existing roof insulation ignited as a result. For Dewies, fire safety became a top priority when considering the resulting renovation of the historic roof and creation of a new roof structure. The solution A ROCKWOOL weatherproof vapour barrier was Carsten Schade and his team were hired to take care installed to ensure the roof was initially protected, fol- of the renovation and rebuild project, and they were in lowed by the ROCKWOOL fire-safe insulation solution for a surprise when they removed the damaged parts for pitched roofs. of the old roof structure – there were actually two roof trusses!

The EnEV poses energy requirements for new buildings, taking the structural heat insulation of the building as well as the energy efficiency of the systems used – heating, ventilation, “You rarely find a beam construction like this,” explains cooling, light – into account. Schade. “An external beam structure with a roof over- hang covered the historic beams where they connected with the outer wall. This was to protect them from mois- ture. In principle, it was a good idea. But in the event of a fire, the fire and smoke could initially go unnoticed in the cavity between the two roof trusses.” Stone wool – naturally fire resistant Insulating a roof is an effective way to minimise heat loss and reduce heating bills and is important to con- sider as a major aspect of any roof renovation project. Non-combustible stone wool was the obvious insu- lation choice for Dewies. Supported by Schade and his team, they decided on a ROCKWOOL insulation solution for pitched roofs that offered heat, noise and – most importantly – fire protection. The geometry of the roof was a challenge when it came to installing the modern insulation, as the large dormer windows at the front and back created many ridges and throats. This made a lot of detailed work necessary, After the renovation, the Hirsch pharmacy reopened for requiring insulation and foils to be carefully cut and business, continuing to serve the community as it had worked on.

The involvement of a large supplier for this small-scale project is really special to experience.” Collaborating for success A floating cement floor was placed on the wooden floor to acoustically insulate the homes. Using the Rockzero building system, based on ROCKWOOL’s stone wool, the apartments achieved exceptionally high insulation values – almost at passive level with an RC value of 6 for the façade and an RC value of 7 for the roof. The building system ensured an optimally insulated and fireproof construction, with no cold bridges. The building plan included the installation of approximately 240 solar panels on the flat roof, to sup- ply tap water, warmed by nature, in each of the homes. Based on the Rockzero building system, the apartments have high insulation values, almost at passive level. It wasn’t the first time that RTR Vastgoed collaborated with Adema Architects.
