Wooden windows and exterior doors - Assembly techniques

A window – or an exterior door – is made up of an arrangement of frames (usually at least two in the case of sash(es) and at least one in the case of fixed frames).

Given the current state of the art, requirements in terms of mechanical strength and durability lead to the elimination of wood-based products that would be agglomerated and could therefore be molded.

Even if the development of wood-based particleboard were to make this solution possible, the extreme dimensional diversity of frames required by the market would make it economically unviable (production/investment ratio).

So, for the foreseeable future, the manufacture of wood-based windows and exterior doors will still involve machining linear profiles and assembling them.

The "Windows and exterior doors" section includes several articles:

• C 3 610 - Basic functions and terminology ;

• C 3 611 - Design of sash frame connection ;

• C 3 612 - Assembly techniques ;

• C 3 613 in which other aspects are covered (filling, waterproofing profiles, installation, thermal, wood, stability).
