Affordable, largely energy self-sufficient buildings!
Timber frame construction has been common building practice for many years, especially in the one- or two-family house sector. The advantage is obvious: high prefabrication therefore little time on the construction site. Especially in the
serial construction, it is no longer possible to imagine the building landscape without this construction technique. In Würselen, there is a start-up company that has taken a closer look at this construction technology together with RTWH Aachen and developed it further.
The founder of the company had the idea to quickly and efficiently build good housing in emergency or disaster areas for people who have lost their homes. After all, tents are only a makeshift and not suitable for long-term accommodation. The reasons are many and well-known.
Exceed KfW40 standard
This gave rise to the idea of improving timber frame construction as a proven building technique with a high degree of prefabrication. And this is done with the help of special textiles and a specially developed PU foam. It is as ingenious as it is simple: the wooden frames are covered on both sides with the 3D textile sheets. In these, two textile layers are connected with numerous threads. This creates a stable cavity, which is filled with the PU foam. After the reaction time, this creates a stable and heat-insulating structure. With a wall thickness of 22 centimeters, the insulation values required by the KfW40 standard are already exceeded.
Further advantages of the resulting walls are: Resistance to water, low weight and, above all, the almost infinite availability of raw materials. The so-called “gray energy” used to manufacture the floor, wall and roof elements is far lower than that of all conventional insulation and construction methods. The low weight further saves “gray energy” during transport.
Wide range of possibilities
The interior finishing with reinforced plasterboard and the facade design also provides the necessary fire and sound protection. The result is a sustainable and, above all, affordable building. The possibilities for use are enormous: from the detached single-family house to the semi-detached house, terraced house to the multi-storey apartment building, everything is possible. Freely and individually planned and created. This construction technology is also exciting for municipalities. Whether daycare centers, schools, offices or housing for refugees, any application is possible.
Exciting and interesting especially because of the construction price: The PMFHouse is due to the low cost of the building materials used with significantly less than 1000 euros per square meter of building area from the floor slab including. Standard windows and doors and a finished roof very inexpensive.
Preventing heat loss MIG, the second company in this network, comes from Salzkotten and has been known for innovations in concrete construction and building protection for over 20 years. The DHMb double hybrid membrane coating developed by this company increases the insulation values of the buildings by simply preventing heat loss through absorption of the wall elements. Thus, the heat remains in the room and is optimized by the back radiation of UV and infrared. The system
is simply rolled onto the wall and begins to act immediately after drying. It also actively prevents the formation of mold or moisture on the walls.
One of the biggest cost factors in residential construction is technical building equipment (TGA). The network solves this problem with the help of the Network for Building Services (NFG). It connects companies in the heating and plumbing industry and provides a ready-made prefabricated bathroom system in different variants. In addition, renewable energy generation and storage is also combined and offered from this network into a very well matched complete system configured to each type of house.
PMFHousing will deliberately avoid water-borne heating systems. This reduces costs both during construction and later during operation. The required heating is provided by modern and innovative infrared systems. Due to the high U-values of the house, the energy required can be reduced to a minimum. Infrared is a heating technology modeled on nature, which, properly planned and used, provides a perfect home feeling.
This also includes intelligent ventilation systems from VALLOX GmbH. VALLOX designs and supplies the ventilation systems that work extremely efficiently with heat recovery.
Hot water is preheated by solar panels and brought to the required temperature by instantaneous water heaters from CLAGE in Lüneburg. The process significantly reduces energy demand, but ensures the availability of hot water at all times.
The perfect interaction of all project participants right from the initial planning phase results in a system building that can be tailored to any need and taste in terms of architecture, yet is highly prefabricated in series.
A new product, the PMFCube, is currently in preparation. Pre-defined dimensions will allow this type to produce small outdoor offices for construction sites and other applications, up to accommodation for refugees. The individual Cubes are prepared so that they can be joined together like containers, stacked or individually freestanding.
