You can choose to see the details of the construction materials below:

The latest generation of Kofinas masonry  is the top choice in energy-efficient passive building system ECOenergy and can reduce the house energy consumption by 75%-80% compare to conventional masonry.

The leading company of the field improves even further the construction, offering the sturdiest prefabricated solution, tested by the National Technological University of Athens!!

  • The timber used for the frame is Swedish pine, planned and furnaced , C24 class. It dows not contain chemical loas and it is one of the top choises worldwide.
  • For the conncections, we use TORX screws which are robotically installed, thus having zero loosening margin through time.
  • Each wall is sealed on each side with Canadian OSB from LP factory, which offers exceptional mechanical strenght. It also offers high impact strenght and allows us to load weights without fear.

(the smaller U value of your climate zone (area) is, the better insulation is needed)

The basic thermal insulation material of masonry. Natural mineral wool offers excellent thermal insulation, sound insulation and fire resistance (category A1-non-combustible materials). Raw materials for the production of mineral wool fiber are amphibolite, dolomite, or limestone and bauxite rocks. The production of mineral wool is done in an electric oven. This method has an advantage over the blast furnace method used so far, because it achieves dimensional uniformity in the fibers produced through the constantly controlled melt temperature and gives a negligible burden on the environment in contrast to that of the blast furnace.

Connection of individual masonry sections using certified TORX studs (ETA-11/0030), which offer a better fit, as they allow better control of the applied torque during screwing.

The wood of the masonry, which is:

  • Swedish: which means that it is really compact.
  • Pine: which means better moisture resistance.
  • Dried: which means that the timber is furniced for weeks, undergoing a natural deworming process, and also reaches the ideal, for house construction, level of humidity which is 15-16%.
  • Ecological: which means that the timber does not contain chemical loads and that the policy of the Swedish Timber Industry aids with the absorption of carbon dioxide.
  • Planned: which means that it has perfectly flat surfaces which, in conjunction with the factory connection methods, we can achieve a perfect assembly with no margins at the joints for all the construction parts of the house.
  • FSC CoC: Which means that this timber comes from controlled forests in which for each tree that is cut they are planted in place of 3 more.
  • C24 class: which means that it has great mechanical strength, showing up to 80% more carrying capacity when compared to conventional timber.

Sealing the base of the wall using impregnated beam, type USE- Class 3. They protect the logs from damage that could have potential moisture on the concrete base, improving the durability of the house.
