FinnCopan

 

Wood-frame walls require significantly less wood than the walls from timber. Frame walls can have ideal heat and sound insulation characteristics. FinnKopan frame walls manufactured in our factories using pre-cut technology is completely ready for assembly. All parts have necessary dimensions, trimmings, holes, as well as all necessary fixture system.  Finnkopan walls can be assembled quickly and without much effort due to the simplicity in construction and there is no need to saw, plane or drill.

 

  1. Exterior panels, 28x180mm, pine
  2. Cross corner joints, imitation of the beam 202x180mm, pine
  3. Wind-resistant board, Runkoleijona 25mm
  4. Framework battens 45x145mm or  45x195mm
  5. Thermal insulation Ecowool (the thickness corresponds to the frame’s width)
  6. Air-proof paper Kraft VCL
  7. Interior siding panels 20x180mm

Supporting structure in such houses is a wooden frame. It consists of upper and lower studs, pillars, and other elements. Like all other wooden structures it is made of pine. For supporting structures it is important because pine is stronger than spruce in the same moisture conditions. Selection of the boards for the frame depends on thickness of the chosen insulation.

The boards 45x145mm (Battens) and 45x195mm (Diels) are mostly used.  For northern areas with long cold winters, we have developed FinnCopan Plus walls, which differ from the regular FinnCopan wall by an additional insulation layer of Ecowool.

 

Finnkopan walls can be made so that exteriorly they will not look different from log walls. This is achieved with the exterior and interior siding of the walls panels profiled identically to a log profile. Panel thickness can be varied. We recommend using the 28 x180mm panels for exterior siding and 20x180mm for interior siding. However, as a rule, the type and size of the siding material is chosen by the future owners of the house after they are consulted by our experts about the pros and cons of all possible materials. The exterior wall corners can imitate the corners of glued laminated timbers but can also be made into a ‘city’ style.

Wind resistance of the walls, thermal and sound insulations is achieved mostly due to the use of modern and environmentally friendly tested materials.

Runkoleijona brand windproof frame is installed between the exterior siding and the insulation layer.  This certified fiberboard meets modern ecological and fire safety requirements. It is tight enough and at the same time porous, it has excellent thermal conductivity (0,056 W/mK), protects the house perfectly from wind and at the same time, it allows the structures to ‘breathe’.

Natural insulation Ecowool is a blowing insulation filling all voids in the walls. This technology prevents insulation shrinkage.  Ecowool is a lightweight (density 35kg/m3) natural material that breathes, but does not require the traditional vapor seal and does not have operational service limitations.  The thickness of the wall may be different. The optimal thickness is 145mm and 195mm, but depending on the climate conditions and wish of the future owners, the thickness can vary.

A laminated paper ELT-KRAFT VCL is used as another wind barrier. It is a vapor barrier Kraft paper from two layers of paperboard. Between the layers of cardboard there is a PE-film which has vapor barrier properties and reinforcing mesh layer which gives an extra strength to the material.

Due to the wall structure which excludes the cracks and formation of the “cold bridges” as well as high thermal qualities of the natural cellulose insulation (0.032-0.041 W/mK), the houses built using the FinnKopan technology are ideal for year round living in any climate. The walls of the house as well as the walls of the usual wooden house ‘breathe’ and keeps temperature and moisture content balanced inside the house.
