Blockbau Rahmenbau and Tafelbau as alternatives

In wooden houses, a variety of construction methods can be distinguished, each with their own advantages and disadvantages. Where panel construction, frame construction and block construction have their strengths, you can read in detail in this post.

block design

The block construction is the oldest of the known timber constructions. The Swiss call them stain construction when the wood is square-edged ("spotted"). In some areas the term knitting is still known.

method of construction

When building houses made of wood, the block construction is the most massive design. On a foundation of so-called foot trees - alternatively on a stone or concrete foundation - the individual sawed logs are stacked.
At the corners of the house, so-called intermeshings are applied so that the timbers are firmly interlocked with each other. These intermixings are also called "rooms" in technical jargon. There are several possibilities in the construction:

  • toothed inner walls, which are also solid
  • Cutting and galvanizing the protruding corners to facilitate cladding
  • firm joining of the woods to each other (tongue and groove, pegging, nailing)
  • Subsequent sealing or the wood does not finish flush with each other

Advantages and disadvantages

For a long time, the log house was considered obsolete because it is flammable and, unlike more modern construction methods, rather less durable. However, fire-resistant construction methods are used in modern timber construction, and durability has also improved.
Today, log houses are mainly offered as prefabricated houses, with prefabricated walls. An interesting building material is polar pine wood, which has a natural temperature-compensating effect.
Main advantages are:

  • high thermal insulation capacity (the requirements of the EnEV are achieved even with single-shell walls, energy efficiency house is possible with little insulation)
  • comfortable room climate (dust-free, wood scent)
  • natural climate compensation in the house

frame construction

There are different names for this type of construction: timber frame construction and timber frame construction are generally synonyms for the frame construction method. However, in the case of the stand construction, the wood studs reach below the roof and form the main supporting structure of the building.
The construction can be done in different ways:

  • Balloon framing with continuous wall posts from the ground floor to under the roof (largely corresponds to the stand construction method)
  • Platform framing, which is built on a floor-to-floor basis (corresponds to the rough-wall construction used in the Middle Ages)
  • Light Gauge Steel Framing (construction with lightweight steel frame, but similar to the platform framing built, wood materials are only used more for planking)

truss

A special form of frame construction is the framework construction. The space formed by uprights and cross connections is filled with various wall materials, but the support function is taken over by the truss alone.

Advantages of the frame construction

  • lower wood consumption than in solid construction (block construction)
  • no special training required for the construction (fewer skilled workers)
  • standardized building material, thus faster progress, overall less labor needed
  • less transport weight (lighter construction materials)

panel construction

The panel construction is mainly found in the farmer industry. Here prefabricated "panels" - whole walls and ceilings - are used for building a house.
Houses in panel construction can be set up in 1 - 4 days due to the high rationalization of the assembly. Therein lies their main advantage. Further advantages are:

  • good heat storage capacity through prefabricated elements
  • ecologically harmless construction materials possible as a system kit
  • better statics for special constructions

However, the disadvantage is probably the low customizability and a small loss of space due to thicker walls compared to the solid construction.
