Urban Construction with SWISS KRONO MAGNUMBOARD® OSB

31. August 2018 | The ideal massive timber construction system for mastering the challenges of urban building

Climbing rents, the need to spend months to find a new home and crowds at open house viewings: these are some of the symptoms of the shortage of high-quality, affordable living space in cities. A study by the German Economic Institute in Cologne found that it will be necessary to build around 350,000 new flats a year until 2020 to meet demand. There is therefore an urgent need for action, especially to overcome the shortfall in relatively low-rent housing. The discussion revolves around urban infill with building of new houses and upwards extension of existing structures.

Modular construction with timber and engineered wood products is capable of creating living space fast. SWISS KRONO OSB in particular is ideal for fast, energy-efficient construction to meet the challenges that cities face today.

Licensees use large-format, solid SWISS KRONO MAGNUMBOARD® OSB made from SWISS KRONO OSB/4 to sculpt bespoke wall, ceiling and roof modules. SWISS KRONO MAGNUMBOARD® OSB is an officially approved timber construction system with enormous potential for building more efficiently and cost-effectively than is possible with conventional approaches. Modules measuring up to 18 x 2.4 metres with a thickness between 75 and 250 mm are then very quickly assembled into lastingly airtight buildings with a minimum of joints.

Adaptable Timber Construction System with a High Level of Prefabrication

The system is highly versatile. SWISS KRONO MAGNUMBOARD® OSB is suitable for both new buildings and the addition of storeys. The modules also enable constructions with large loadbearing surfaces, making them ideal for vertical and horizontal extensions and refurbishing projects. Existing structures aren’t damaged or compromised in any way, as it is a dry construction system (as opposed to masonry and concrete).

As SWISS KRONO MAGNUMBOARD® OSB can be very flexibly prefabricated without the need to follow a prescribed grid or layout, it is straightforward to adapt new structures and annexes to pre-existing architectures, building exteriors and proportions. The system excels both as a complete construction solution in its own right and in combination with other building methods.

SWISS KRONO MAGNUMBOARD® OSB modules can also be used without problem to erect taller and subterranean buildings with larger units (building classes 4 and 5 in Germany). And because they are so homogeneous, it is easy to calculate the burn rate according to DIN EN 1995-1-2. What’s more, there are tested constructions that resist exposure to fire for 30 and 90 minutes to serve as models.

Fast & Easy Assembly on Small Building Sites in City Centres

The extensive prefabrication and large-format modules greatly speed on-site assembly. A storey or even an entire house can be put together and sealed against the weather in just a few days. This delivers clear advantages for everyone who is directly or indirectly involved or affected. Time-consuming setup of large building sites with storage areas for materials such as bricks, concrete and small parts is largely eliminated, as the modules only need to be transported and immediately assembled.

This means no more weeklong blockages of roads and pavements, fewer traffic jams as a result of labyrinthine traffic diversions and less noise and contamination inflicted on neighbours. New dwellings can be occupied almost immediately to start generating rental income. And as the walls are thinner than with masonry and concrete construction, there is more indoor living space.

Housing construction is additionally speeded up by the fact that many kinds of plaster, tiles, wallpaper and paint can be directly applied to SWISS KRONO MAGNUMBOARD® OSB interiors without the need to first attach plasterboard and then apply, trowel and sand filler. This not only saves time but also slashes costs for materials and labour.

High-Tech Engineered Wood Materials to Benefit the Environment and Achieve Healthier Living

Today owners and tenants are also attaching ever greater importance to energy efficiency, sustainability and healthy living conditions. As timber and engineered wood products are outstanding in these respects, in addition to their excellent thermal and acoustic insulating properties, they have long since emerged from the shadows cast by other building materials. Wood has a good natural storage capacity, which makes it ideal for energy-efficient construction. SWISS KRONO MAGNUMBOARD® OSB in particular, due to its high density, ensures a pleasant indoor climate in winter and summer alike.

Along with the natural Rotkalk plaster system from KNAUF, SWISS KRONO MAGNUMBOARD® OSB was rewarded a certificate for good indoor air quality by the Institute of Quality Management and Environmental Hygiene, which had carried out measurements in a pavilion in Wald-Michelbach in Germany’s Odenwald region where the two products had been used together. KNAUF Rotkalk regulates humidity and absorbs odours, resulting in an optimal indoor climate when used in combination with SWISS KRONO MAGNUMBOARD® OSB.

Wood is also a renewable material that offsets climate change by sequestering carbon dioxide, thus lastingly extracting this greenhouse gas from the earth’s atmosphere.

Eco-friendly and food safe with a minimal tendency to shrink or swell: the list of the benefits of SWISS KRONO MAGNUMBOARD® OSB is long. Modern engineered wood products are high-tech and excellently meet expectations for building and living in metropolitan areas. SWISS KRONO MAGNUMBOARD® OSB lends itself for creating attractive, sustainable and affordable living and working space in city centres, thus ensuring greater quality of life.
