Fronts assembly technology

Assembly technology of wooden fronts: advantage of "Sihga"

AUSTRIAN SIHGA SYSTEM «SAWN TIMBER FILLED WITH INSULANT» BASED ON COMPOSITE AND ALUMINIUM VENTED FRONTS SYSTEMS

Best technology for wooden fronts!

System Installation starts after walls thermal insulation and audit completion.

Works performed in a manner of continuous cycle.

Clear process division by stages:

  • frame
  • lamella installation
  • Painting

The front is essentially dismountable!

Maintainable that makes the service easy.

The front board width is strictly limitable: 68, 72, 92 mm. These are the sizes of German standard which guarantee maximum stability.

Patented anchors layout for 15 and 90 creates a high sustaining capability (supports the load up to 120kg per 1 anchor) i.e. over 300kg per 1 sq.m.

Standard weight of 1 kg of front construction - 15 - 25kg!

FassadenClip fasteners provide profile lateral stability without creating a rigid profile jamming.

Easy frame adjustment at any stage.

Technology by which the roof is usually insulated. I.e. thermal insulation fills the space between the roof coatings and then protected with finishing material.

  • Installation of the guide bar (lag) on the wall, mineral wool insulation material between the timbers;
  • Installation of wind barrier and (or) waterproofing.
  • Rear rack mounting
  • Installation of front lamella

 

Wooden lamellas installed on the subsystem for aluminium or composite front systems.

 

DISADVANTAGES:

When installing the system above the third floor it is necessary to install fire prevention.

Time spent is three-fold more than when using Austrian technology – guiding rail is installed two times!

Irrational massive crossbeam is used. Cross-section, of course, must be greater than the thickness of insulation material (for example, 150mm at a thickness of slag wool of 100mm).

There is no possibility of subsystem adjustment and alignment during operation.

Wind barrier does not work properly since it is attached to the frame by mechanical means.

Counter batten does not provide sufficient rigidity.

There are gaps between the stages of works performance, during which the frame bending is possible.

Subsequent adjustments to frame geometry are not possible.

Labor intensity is also increased due to the necessity of sealing (foaming) of joints between the frame and wool. When attempting to adjust frames the sealing of joint is broken.

Undismountable design (use of rivets) using hidden fittings.

Weakening of wood body due to seats profiling for fittings.

Wood physics is not considered, namely: often wide wooden lamellas are used – up to 150 mm that always leads to their transverse deformation.

Lack of the possibility to adjust the frame in the course of work, only at the beginning of work.

No correction capabilities of the natural curvature of lamella or drawing of the front.

Complicated work on the board layout.

Undismountable design ( rivets used for aluminum)

Inability to compensate for lamella curvature. There is no possibility to adapt the frame to the wood pattern (cutting).

THERMAL PHYSICS:

Bezifix insulated anchors do not create the cold bridge through the insulating wall layer

Conventional anchors create cold bridges into the wall. There is heterogeneity and discontinuity of thermal circuit

Standard indicators for vented fronts

CONCLUSIONS:

Optimal and fast system for all types of walls with or without insulation.

Material-and labor-intensive "homemade" system used in low-budget construction sites.

Perhaps it is useful to apply during construction of frame houses, since the frame of the house itself serves as foundation for a wooden front.

Professional subsystem designed for stable materials with a constant geometry: stone, aluminium, composite materials.

Without taking into consideration the physical and mechanical characteristics of wood.

It is proposed usually by the companies that do not have experience in implementation of projects related to wood and professionals working with wood.
