The latest generation of KOFINAS masonry is the top choice in passive ECOenergy building and achieves a 75%-80% reduction in energy consumption compared to conventional masonry.

The leading company in the field further develops its construction and offers the most robust construction in the field of pre-construction, tested by the National Technical University of Athens!

  • the wood of which the frame is made is Swedish pine, planed and fired, class C24. It does not contain chemical loads and is one of the top choices worldwide!
  • The connection is made using screws (TORX), which are placed robotically, so we have zero loosening of the connection over time!
  • Each wall is closed on both sides with LP's Canadian OSB, increasing the mechanical strength of the wall. It also offers the highest impact resistance and allows us to hang loads on it without fear!

OSB of the LP factory is placed on the exterior of the exterior wall and roof construction  class 3- APA with enormous mechanical properties. This material statically reinforces the masonry and gives the possibility to fix any weight at any point of the wall, without special addition.

The basic heat-insulating material of masonry. The 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 the rocks amphibolite, dolomite, or limestone and bauxite. Mineral wool is produced in an electric oven. This method is advantageous, over the blast furnace method applied until now, because dimensional uniformity is achieved in the produced fibers through the constantly controlled temperature of the melt and it yields a zero burden on the environment in contrast to that of the blast furnace.

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

With these metal corners, the construction is ABSOLUTELY connected to the reinforced concrete base. In this way, we have a "bonded" construction with INCREASED MECHANICAL STRENGTHS and IMPROVED ANTI-SEAMIC BEHAVIOR.

It provides insulation to the construction and protects against moisture, without allowing the appearance of water vapor that could gradually cause damage to the construction.

Masonry timber, which is:

  • Swedish: which means it is very compact.
  • Pine: which means greater resistance to moisture.
  • Dryer: which means that the wood is cured for weeks and disinfected naturally and not chemically (like green wood), while the humidity reaches the ideal, for residential construction, level of 15-16%.
  • Ecological: which means that the wood does not contain chemical loads and that the policy of the Swedish Wood Industry contributes to the absorption of carbon dioxide.
  • Planned: which means that it has perfectly flat surfaces, which, in combination with the factory connections, achieve absolute assembly and zero joints in all the construction parts of the house.
  • FSC CoC: Which means that this wood comes from controlled forests in which for every tree that is cut down, 3 more are planted in its place. 
  • Class C24: which means that it has very high mechanical strengths showing up to 80% a higher load-bearing capacity than ordinary construction timber.

The KOFINAS company makes special orders for the masonry base from Sweden.  

The waterproofing of the base of the wall is carried out using a impregnated beam, type NP5. The wood maintenance class A and AB (Class A and Class B) of the wood we supply implies the treatment carried out in accordance with the penetration class NP5 which is configured according to the SS-EN 351-1 standard. In this way, the base of the masonry is protected from damage that could be caused by possible moisture in the base from the concrete, improving the durability of the house over time.
