The main differences between timber frame construction and steel frame construction
02 May 2019
Steel frame construction or timber frame construction?
A construction method that uses many load-bearing elements with a limited section is frame construction. This method is based on load-bearing frames that can be filled with insulating material. One of the most important things concerning working with frames is the possibility to automate and prefabricate the systems.
Just as a variety of materials can be used in traditional construction, many options exist for frame construction. The main differences between steel frame & timber frame can be found below.

Steel frame construction
Construction
- Frame constructed from steel profiles (C or U)
- sheet elements provided by structural sheeting (osb, Durelis, etc.) or wind bracing
- anchoring with foundation using standard or chemical anchors
Insulation
- In the frame:
- Rock wool or fibreglass wool (acoustic insulation)
- External frame: Insulating plating (thermal insulation)
Spans
- Large span & cantilever possible
- Use can be made of trusses or hot rolled steel
Comparative characteristics
- Corrosion, moisture and vermin resistant
- Shrink-free
- Light in weight/can be moved manually
- Architectural freedom

Timber frame construction
Construction
- Frame constructed from wooden framework
- sheet elements provided by structural plating (osb, Durelis, etc.)
- Anchoring of foundation by means of chemical anchoring
Insulation
- In the frame:
- Rock wool or other
- External frame: insulating plating
Spans
- Limited span & cantilever possible
- Using wooden I-profiles/beams
Comparative characteristics
- Sensitive to moisture & vermin
- Wood moves: shrinkage and creep damage
- Heavier than cold-formed steel profiles
- Sustainable
- Limited architectural freedom
