Ventilated Flexyhome Masonry

Tested by the National Technical University of Athens, surprising specialists and scientists, the construction system of KOFINAS company is externally covered with CanExel, creating the flexyhome, a construction that lives up to all your needs!

 

The thermal permeability coefficient of KOFINAS masonry is:

U=0.30 W/m²K

MAXIMUM ALLOWED THERMAL CONDUCTIVITY VALUE (U) PER CLIMATE ZONE

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

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.

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.

Certified material (certification EN13163) with high thermal insulation capacity. It is self-extinguishing and waterproof. It also functions as a water vapor barrier. In addition, it has sound insulation properties.

Wooden joists of Swedish timber (dryer-baked, class C24) with particular resistance to distortion. As a result, the ceramic roof is highly resistant to time and severe weather conditions.

The CanExel siding carries all the advantages of wood, like the ease of installation and the insulating properties, without suffering from distortion, humidity absorption and edge wear.
It is provided at the factory with a durable coating finish, which is factory-colored according to your choice from a wide variety of colors, that requires no further treatment.

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.

The ceramic roof membrane is 3 layers, vapor permeable (breathable), but completely waterproof. Protects roofs from condensation, rain, snow, dust and all weather conditions. Due to its high vapor permeability, it simultaneously allows the ventilation of houses from the inside.

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.

Sliding joints which allow for a quick, easy and highly durable connection of the masonry parts. They are pre-installed and pre-adjusted.

Waterproofing of the base of the wall using an impregnated beam, USE-Class 3 type. They protect the logs from damage that could have possible moisture in the base from the concrete, improving the durability of the house.
