MATERIALS AND CONSTRUCTION SYSTEMS: RESEARCH, NATURE AND TECHNOLOGY

Aktivhaus’ highly energy efficient buildings are based on natural materials and a multi-layered system adaptable to any architectural solution, together with a combination of high technology and research into increasingly environmentally sustainable solutions.

AKTIVHAUS PANELS

The X-LAM panels used in Aktivhaus buildings are manufactured through a certified production process, thanks to compliance with ETA procedures; they have CE marking and are designed from studies and static calculations, as required by the technical regulations for buildings (Ministerial Decree 14.01.2008).

According to the specific design requirements, X-LAM panels may be used for the construction of walls and floors. Thanks to their excellent mechanical properties, they are ideal for earthquake-resistant buildings. Made almost exclusively with timber from sawmills certified by the PEFC (Programme for the Endorsement of Forest Certification), they are biocompatible and sustainable.

NATURAL MATERIALS

The construction materials and elements are natural and regenerate: for example, the X-LAM load-bearing timber structures are made with an adhesive that is totally free from formaldehyde and solvents, and 100% non-toxic.

All the insulation materials are carefully chosen for the best technical qualities in terms of biocompatibility: examples include cork, wood fibre, cotton and sheep’s wool, all of which are breathable.

Wherever possible, Aktivhaus gives preference to the use of locally produced raw materials, which promote respect for a balanced ecosystem and blend in with the environmental context.

MONOLITH SYSTEMS

Aktivhaus has studied and designed the MONOLITH systems with the aim of constructing buildings that combine excellent technical performance with unsurpassed living comfort. All the systems used are constantly evolving: new technologies and materials of the highest quality enable increasingly high performance to be achieved. Aktivhaus designs and creates buildings that are tailor-made for each situation: the MONOLITH systems can be customised and adapted to any building. For this reason, the examples in the preceding pages should be considered as merely for information purposes and not limiting in any way.
